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 received 5 on 5 wheels instead of 5 on 4.5 wheels, and getting them replaced has been very difficult.

Paul, I have good news! The replacements are on their way to you!

Great selection and great prices. Got them in less than a week and put them on within an hour. So much better looking on my 5th wheel RV and now peace of mind. I went from a size ST205/75R15 to a ST225/75R15. They fit great! Pictures are before and after.

Great tire and wheel combination. Excellent value! I replaced the brakes and slipped on the new tire and wheel to complete the job. Trailer will be in great shape for many years.

High quality tire and wheel! It was a perfect fit and now my trailer pulls smooth as butter down the road! I highly recommended this tire/wheel combo and this company!!!!

I bought this for a spare, since my livestock trailer did not come with one. It was a great value and now I don’t have to worry about not having a spare.

Outstanding retailer. Products always arrive in a timely fasion. Everything I've ever purchased has been quality products.

I would just like to say that both the ease of using your website and the incredibly efficient way in which my order was processed and shipped blew me away. I shopped on Sunday and had my wheels/tires mounted on my trailer on Wednesday. I wish every etailer was this efficient.

Review from a similar Karrier Steel in Trailer Tires and Wheels

I ordered these to place on my boat trailer. I used them on my 2012 Trailstar trailer which carries my Tracker bass boat. It had load range C tires. I wanted to upgrade my tires and this item was exactly what I wanted. These fit perfectly. The tires were “fresh”....meaning that they were made only a months ago. The finish on the rims was much better than I was expecting. The welds on the back side of the rims looks to me to be quality work.

It’s been a year and I have absolutely no complaints. I would definitely purchase these again.

Review from a similar Karrier Steel in Trailer Tires and Wheels

The tire and wheel assemblies look good. I haven’t pulled the trailer yet so this isn’t an in-use review. I couldn’t give them 5 stars because one of the assemblies needed 4 1/2 ounces of wheel weights to balance. To those of you that would argue they don’t require balancing I say this...if it rotates, if it spins it needs to be balanced! Great prices, excellent shipping services. You can’t go wrong.

Have 6000 miles on these tires now and they are wearing and riding well. I tow at 70 MPH so I balanced the tire and wheel assemblies when new.

Review from a similar Karrier Steel in Trailer Tires and Wheels

Have only put a few hundred miles on them so far, but they seem like quality tires and rims. Order fulfillment and shipping was super quick -- faster than what was estimated when I ordered. I appreciated the quick delivery so I could put them on before a trip.

Its been a year, and theyre in great condition. Was surprised this spring that after sitting in storage all winter, the tire pressure was still right on. Must have a darn good seal.

Review from a similar Karrier Steel in Trailer Tires and Wheels

I received the order on time. The tires were not damaged. I took the tires to get them balanced and things balanced out well. The tires were as described. My first impression was that the tread wasn’t very deep. The old tires I removed had deeper tread. The old tires were light truck tires and the new tires were trailer tires so that may explain why there is a difference. The trailer has been on a couple trips and we haven’t had any problems yet. I put them on my fifth wheel and it is around 12k dry and loaded around 14k. From what I can tell, these are an affordable replacement if you have old tires and rims and need a replacement.

Everything is still working out great! No troubles to speak of...

Review from a similar Karrier Steel in Trailer Tires and Wheels

I purchased Loadstar 5.30 12 Bias Trailer Tire 5 on 4 1/2 Load Range C . I failed to notice that it was a Bias Ply which only has a Load Range C at 65 mph. I got back with etrailer for a refund and replace them with a 175 13 Radial that has a Load Range D at 81 mph . It was a hassle free Exchange. Of course they deducted shipping on my refund. Make sure that's the item you want it will save you on shipping cost on your return. Overall I'm very happy with the Tires and rims and they fit perfectly. Very good customer service. I received them in three days. I would recommend this company. 5

Review from a similar Karrier Steel in Trailer Tires and Wheels

Great products and very good prices on quality tire. Quick shipment and boxed very nicely. Fit on trailer hub perfectly. Videos really helped me measure hub lugs and explain ply difference and load range differences. I have a better product which will haul more. I will be buying a hitch and wiring for another car and the videos show me how easy it is to install. Companies around here want up to $400.00 to install. Thanks for the service will be back

The tires are perfect on my trailer. Hardly ever lose air and so trilled to have good rubber when I go across town. Really easy process on buying tires with a rim. No waiting at store installer and helped me learn to change my own tire. I tell people even lately about this business and how wonderful the experience has been. I used to have a raggedy $150.00 yard trailer someone built and neighbors would borrow until last neighbor called and told me he arrived with only the hitch clasp. Bought me a good trailer later and updated the wheels and tires and don’t worry about accidents so much when pulling a load. Thanks for helping me improve my responsibilities towards others on the road

I needed a spare tire for my yacht club trailer, it was an odd size and you guys had it right in line as I browsed down the wheel sizes on your site, including shipping I got it cheaper than going to the local Marine dealer. Now I need summer to get here.

Needed a spare since purchase of boat, many different tire a d rim sizes on trailers, found the correct one on your site, hole pattern and dimensions were right on.

I'm happy with the Radial Tire and Galvanized Wheel package etrailer helped me with. Between the pictures and video of the product on the website, multiple questions submitted and answers received (even though I interfaced with multiple agents on the phone and email, they're all up to speed on customer information), packaging, product quality, price, ease of purchase, and follow up after receiving the delivery(which was prompt), It's been an excellent experience! I will use etrailer again for future purchases and recommend as first choice!

Review from a similar Karrier Steel in Trailer Tires and Wheels

Tires & rims arrived the next day after placing the order the night before. I was actually caught off guard as I did not expect them to arrive till Monday. Installed them on the trailer later that day. No surprises and they fit perfectly. Old tires were cracked and the rims were in bad shape. New wheels look great !! Very pleased.

No issues, tires and rims working out very well

Review from a similar Karrier Steel in Trailer Tires and Wheels

The tires are a great upgrade to the standard "Carry On" trailer tire. Made a few modifications to the fender well and the results were what I was looking for. We've have taken my homemade square-drop camper out a few times now and rides really well.

  • Should Larger Tires and Wheels be Used to Go Camping on the Beach with a Trailer
    Ultimately you want the most surface area on sand so if you have the means to upgrade your tire/wheel size then go for it! What you need to do prior to purchasing new tires/wheels is to go out and check on your current set to see what kind of clearances you have. You want to have at least 4" of clearance above your tires (for suspension travel) and then at least 2" of clearance between the sidewall of your tires and your trailer frame. With all of that being said, the largest tire you'd...

  • Radial vs Bias Tire for a Boat Trailer
    The difference between Radial and Bias tires is that Radials will run cooler than Bias (making them last longer for highway applications) and they have more flexibility for better ground contact, traction, stability, and tread wear. Bias tires have a stiffer sidewall which makes them ideal for off-road use like on a farm. Since most people transport their boats on the highway I recommend going with a Radial tire. The other thing you will want to pay attention to is the type of wheel...

This combo measures 28.4 Diameter x 8.9" Wide. If you have room for this larger size there would be no downside of this and more upsides than just added height such as a higher speed rating, greater weight capacity, and better tire selection.

Trailer tires are designed with a thicker sidewall that can accommodate higher air pressures and the weight of the trailer load. Trailer tires should also be inflated to their maximum pressure that is stamped on the sidewall. The trailer tires that we carry are not intended to be used at speeds over 65 miles per hour, unless...
