Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.


Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

I was very impressed with my experience ordering from etrailer. I needed new tires for my utility trailer, the website had helpful videos and information to ensure that I was purchasing the right product. My order was processed and delivered free of charge and I had my new tires within the week 715157

Tires were ordered on Good Friday and showed before noon on Tuesday. Great service as expected. The tires are very nice and there was no shipping damage. I think they will work great on my camper for this years long distance tow. Only little complaint is that the rims don't look like a lot of finish work went into them. They are rough, almost look like they were spray painted rather than galvanized. Surface has drips and runs. But otherwise is well covered and I don't anticipate them rusting like my old white painted rims did. They may look better with a bit of hand polish work. But they are trailer tires not mag rims on a GTO so I can live with it. 183877

Tires and wheels both look good, the galvanized is a nice change from just painted. If you want even better looking, you'll have to get the aluminum wheels. Customer service was excellent. UPS broke the box and lost one tire, etrailer folks worked with me and them and got a replacement wheel/tire out to me. When UPS found the missing tire, they dropped it at my house and I contacted etrailers to buy it as well to use as a spare. I loved that they stayed in email contact with me on an almost daily basis as we tracked down what happened. Only took a week to sort it all out, and two days of that was because I let the initial box sit without opening it up. Tire wheel price combo seemed higher than some, but I got free shipping, which more than made up for the difference and made these guys the best deal. I would definitely buy from them again 172789

Bought three of these tires and selected the galvanized option for use on my boat trailer. Another reviewer commented on the quality of the galvanizing. My rims looked as if it was sprayed on vs. dipped as well. However, for my application looks less important than function. The three tires individually balanced with weights ranging from minimal to heavy. one required weights on both sides of the rims. I've had them out for a hundred mile round trip and they performed well. So far very satisfied with ease of ordering, prompt shipping, customer follow up and price. If tires hold up well will upgrade rating. As an aside... very impressed with the wealth of information this site makes available to the consumer. 195301

A year ago I promised to upgrade my rating if he tires held up well. They did and I will. Five Stars! Put about 2000 highway miles and numerous dunks in various lakes. The tirres hardly look used and track true. The galvanizing has done its job as well. No issues with rust. Im satisfied with the tires and rims. will consider again when time.

Tire and rim look very good. I will be used as a spare on my boat trailer. Shipping was very fast. Havn't had time to mount it yet. 426465

I ordered this tire wheel combination because its simpler to order combination than just buy tires and not that much more expensive. I also wanted to change to galvanized wheels so combo was the way to go. I also wanted load range D and hopefully a better quality tire than readily available locally , which I hope this turns out be. I have had extensive experience with large and small trailers including jet ski pontoon and ski boat, equiptment trailers, goosenecks, 4 wheeler / lawnmower trailers and john boat fishing boat trailers which this purchase was for. Essentially all the 13 inch and under down to 8 inch trailer tires I have ever had failed from sidewall cracking aging . Hope the rubber in this tire is more like normal car tire formulation. Only time will tell. The tires arrived in 3 days as indicated when ordered and order was correct. The condition of the tires was as expected with no observed defects they were also pre inflated . The one thing that prevented me from giving this a five star was the quality of the galvanization on the wheels. In some areas there was excess small sheets of the galvanized coating hanging off wheel near tire bead edge and between the spokes. This excess pulls off easily but makes me think it will leave a small crease of unprotected metal. Only time will tell. I do believe the wheels will look better 3 years for now than the painted ones I had and am using as spares. The website was fairly easy to use but the choices could have been further filtered to galvanized etc wheel and especially load range and Bias vs Radial tires . It took a while to go through the 25 or so choices then I placed possibles in cart then went to cart to review those and remove all the ones I did not order. Overall very good experience with shopping and ordering and I have ordered from here several times. 607207


Comments
There are a few things you can do to maximize the longevity of your tires. 1 Observe the weight rating. Exceeding the weight rating will cause a high heat build-up, which decreases tire life. 2 Observe the tires speed rating, for the same reason as above. 3 Maintain the tire at the full pressure listed on the tire sidewall. If the tire is underinflated, its load bearing capability will be reduced. Trailer tires are meant to be operated fully inflated unlike passenger vehicle tires which can have an acceptable inflation range. 4 Protect the tires from UV rays if the trailer is stored outside. UV rays from sunlight cause the rubber compounds in tires to break down prematurely. Trailer tires should be replaced around the 6 year mark, regardless of tread condition. At 6 years, dry rot will start to be a problem.

Compared to the previous wheels and tires I had on my trailer these are great. The others would loose a ton of air over time compared to these. Other than topping off the tires during some cold weather the air is always right where I left it. I havent had any issues with bubbles in the sidewall like my other tires. Maybe that is the extra weight rating actually doing something or maybe its all in my head but it makes me feel better. The price was awesome too - new rim and tire for less than my old tires. Yours might need to be balanced. I took mine to get balanced before I ever put them on and they both got a weight. All around extremely happy with these tires 1 year in. 756607

Fast shipment and tires with rims were as described. Galvanized coating on the rims is a little rough but acceptable considering the overall price. They worked great on the hwy at 70 mph. Tires and rims are well balanced. Have purchased multiple times from etrailer and plan to continue to do so in the future. They excel with the online sales process, website product info, and customer service. 733172

Ask the Experts about this Kenda Tires and Wheels

  • Is it Necessary to Fully Balance Trailer Tires
    First, thank you for your many purchases from us here at etrailer, including the Kenda Karrier tires # AM31994. Trailer tires that we sell come from the distributor already mounted to the rims. These do NOT get a full dynamic balance the way new vehicles tires do but they don't actually need this. When the tires are mounted to the rims the light spot on the tire is matched to the heavy spot on the wheel. This provides a degree of balancing that is sufficient for trailer tires. You...

  • Do Trailer Tires Come Already Balanced
    The pre-mounted trailer wheel/trailer tire products we sell, such as # AM31994, are not dynamically balanced the way vehicle wheels/tires are. Trailer tires do not really need to be fully balanced the way vehicle tires do but you could have them balanced if you wanted. These items are mounted together so that the wheel's heavy spot mates up to the tire's light spot; this is not the same as a full dynamic balance but it is fine for trailer use.

The 195 -75r 14 size you mentioned is a passenger vehicle tire size and definitely should not be used on a trailer.

This combo have a load range D which is 1,610 lbs at 65 psi and has a max speed rating of 81 mph. The galvanized finish on the wheel is perfect for marine applications. It is a bit of a rougher finish and helps to keep the steel wheel from rusting and corroding. If you would rather stick with...

  • Will 175/80-13 Tires Fit in Place of 185/80-13 Tires on a Cox Tilting Boat Trailer
    First, if your current tires have a P in front of the size that indicates they are likely passenger vehicle tires which should not be used on trailer due to the differences in construction. If they are trailer tires, they should have ST in front of the size. A 185/80-13 is a trailer tire size. Check the trailer tongue for a plate that lists the capacities and should also list the tire size the manufacturer uses for the trailer. That is the size you would ideally want to stay with. Both...

  • Choosing Between Galvanized Trailer Wheels and Aluminum Trailer Wheels for a Boat Trailer
    In the galvanizing process, depending on how the manufacturer dries the wheels some of it can pool on one side due to the dipping processed used. That is an issue you are going to run into with many wheel manufacturers. It is an ongoing issue. What I recommend is to go with an aluminum wheel and tire combo like # AM31998, # AM32001HWTB, or # AM31245. You pay a little more but you still get excellent corrosion resistance, style, and none of the issues associated with galvanized wheels.

    It sounds like you may have measured incorrectly, though you were on the right track. There are actually a couple of ways for you to find your bolt pattern.

The other method would be to use the distance between the center of one bolt hole to the center of the bolt hole adjacent to it.

  • Replacement Tire Recommendation for Trailer with ST175/80R13 Tires that are Failing
    You always want to have your trailer tires inflated to their max PSI rating. There is no exception for this for tandem axle trailers. Typically trailer tires fail due to excessive heat created by overloading, exceeding the speed rating (typically 65 mph), or under-inflation. The most likely situation is that you are exceeding the speed rating and that is causing the failure since you are above the weight rating for 4 Load Range C tires.

  • Which Trailer Tire Size Replaces B78-13B Tires
    B78-13 is an old tire size designation that isn't used much anymore. The modern trailer tire equivalent size is ST175/80-13. All of the tires on the trailer should be the same size, load range, and construction type (radial or bias ply). Having one that is a different size can cause uneven tire wear, tracking problems (how the trailer follows the tow vehicle), potential suspension issues, and unspecified weight carrying capacity. The 175/70-13 isn't a trailer tire size. If the tires...

  • Do the Trailer Rim and Tire Combinations Come Balanced
    The trailer tire and wheel combination is received from the supplier already with the tire mounted on the wheel. The supplier does not balance the combination, but when the tire is installed to the wheel they will line the high (heavy) spot on the tire with the low (light) spot on the wheel. This does not completely balance the tire and wheel combination but it does eliminate any excessive out of balance condition. I would recommend to balance the tire and wheel combination at a local...

  • Can ST175/80R13 Radial Trailer Tire Replace 165/80-13 Size Tire on Boat Trailer
    Your current 165/80-13 size tire has a section width of about 6.5" and an overall diameter of about 23.4".

  • Solution for 14 Inch Tires Rubbing Against the Fender
    We do not recommend using spacers because it can cause otherwise avoidable issues with your tires and hubs. There are not smaller 14 inch tires and because you do not want to remove the fenders the best option is going to be replace both your wheels and tires with a smaller capacity. The most important thing to know before doing this is what your hub's bolt pattern is. The most common is 5 on 4-1/2" although if you are unsure you will need to take some measurements to find out and I...

  • Bolt Pattern and Recommended Wheel and Tire for Salt Water Boat Trailer with ST175/80r13 Tires
    It would be odd for the 4-1/4 inch measurement to be accurate. I've attached an article on measuring bolt pattern for you to confirm your bolt pattern before ordering. You also may choose to use the Redline Bolt Pattern Template # BC-TEMP to confirm. If you do end up with the same measurements, you may want to consider changing out your hubs as that isn't a standard size. Based on your wheel size, I believe you will have a 5 on 4-1/2 inch bolt pattern and recommend the Provider ST175/80R13...

  • Are Kenda Karrier Trailer Wheel/Tire Combos Factory Balanced
    The wheel and tire combos we sell are not balanced at the factory. When the tire is mounted to the wheel, the high (heavy) spot on the wheel is matched to the low (light) spot on the tire, which leaves the wheel and tire somewhat balanced. You may have the wheel/tire professionally balanced if you wish, but having perfectly balanced tires is not as important with trailer tires as it is with a passenger vehicle. I have linked you to our Tire and Wheel help article that contains more...

  • Does Karrier ST175/80R13 Radial Trailer Tire Come Balanced
    The tire and wheel combos we carry like the part # AM31994 are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you wanted to. What our tire manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing but not like how car tires are balanced (with weights on a balancing machine).

  • Wheel and Tire Recommendation to Give Additional Ground Clearance Over a 175/80R13 Tire
    The old tire size B78-13 is actually very close in size to the 175/80-13 that you currently have so I would not recommend going to that size to gain ground clearance. The only bigger 13 inch tire that we carry than the 175/80-13 is the 185/80-13 which only gains you about .3 of an inch so it probably wouldn't be a worthwhile upgrade. The best possible upgrade I could recommend for you would be to go with a 14 inch rim and a slightly larger tire, assuming you have the clearance for...
