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"

Kenda Karrier ST145/R12 Radial Trailer Tire with 12" Black Mod Wheel - 5 on 4-1/2 - LR D - AM35354

Average Customer Rating:  4.8 out of 5 stars   (3577 Customer Reviews)

Radial tire has a ply rating of 8 and a 1,220-lb maximum load at 65 psi. The 12" diameter x 4" wide steel trailer wheel has a 5 on 4-1/2 bolt pattern and a corrosion resistant, black powder coat finish.


If you're on the fence, just buy them! I got these to replace the bias 4.80-12 tires that came with the trailer. These are light years better. They have a modern automotive style tread, plus they are M speed (81MPH) rated! The gloss black wheels look cool too. They have a much wider and flatter contact pattern with the ground, and while slightly larger diameter, they fit the stock 12" wheel fender perfectly. I've got a lot more peace of mind towing my utility trailer at highway speeds now.

One year later, and these are still great tires. Super smooth and straight at high speeds on the highway. No complaints!

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.
Ed f - 01/13/2021


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.


Great looking rim and definitely a better tire than what comes stock on my trailer. My trailer is brand new but came with Bias tires which I don't trust at all. Radial tires track much better, have a flatter tread which tracks better and are overall a stronger tire in my mind. The trailer came without a spare so I used one of the original Wheel as a spare .


Awesome service. Placed order for galvanized tires on Sat, heard back same day that they were on backorder and if i wanted to switch to the cheaper black ones. These radial tires are a great replacement for my 12 in bias-ply tires — needed to change them out for a longer NE to South FL tour. Definitely would buy again.


Called etrailer to see if these wheels would work to upgrade from 8” wheels to 12” on my trailer. They agreed that these would work. Wheels arrived two days later, and fit perfectly. Top notch customer service experience.


Super fast shipping. Wheels and tires look amazing, huge upgrade over what I had on there. Piece of mind now on the interstate. Going to buy another for a spare. Thanks etrailer!


great service ,good pricing speedy delivery will be a forever customer .
I have purchased 20 rims and tires in the last 5 weeks for a custom trailer.


Arrived on time and replaced my old bias ply tires perfectly. The black wheels have a great finish.


Great Job etrailer !!!!!!! you have a customer for life. Love my purchase and thanks for the great customer support from Troy H. If anyone wants to jump from the 4.80x12 or the 5.30x12 wheels and Bias tires to Radial tires ST145/R12 on Black or White Mod wheels then this will be a perfect choice and fits perfectly. Thanks again.

Wheelstires combo are awesome so glad I made the purchase and jumped up in tire size and it fits with no complaints. Thanks again Etrailer
William - 02/16/2019


Bought for a matching spare for my trailer. Competitive price, quick delivery. Also, ordered hub caps in picture. Improves the look.


Replaced 12" Bias Tires with these. Have only done a short test run with the trailer, but all seems well. These tires are slightly larger in height and width, but I don't think that will be a problem.
Trailer is a Carry-On 6' x 8' mesh floor landscape trailer. We tow dirt and road bikes with it.

After a year everything is still fine with the new tires. Much better tread wear than the Bias tires that came on the trailer.
Dave - 07/23/2018


Excellent product and the service was great too. A little larger then the original tires on my trailer which worked out great.


Very nice tires and finish on the wheels. Higher payload yet slightly smaller than my old tires so they fit under the fenders better. Shipped and delivered on time so all in all I am pleased with my purchase.


Very nice looking wheel and tire! So far I had these on my kayak trailer and they ride well.


Very happy with the two tires on pontoon trailer. I must have hit a heck of a pot hole as I bent the crap out of wheel. Caused a slow leak. Ordered a new one and delivered as promised. Tire guy worked on old wheel and bent back in shape so I use it for spare


Great wheel and tire package! Looks great and alot better tire than the stock bias tire. Went from a 4.80x12 to st145r12. Its perfect for my application.


Tires and wheels have held up well to interstate travel. More than please with this purchase


Nice upgrade to the stock skinny white factory wheels on the Seadoo trailer.


I am so pleased. Service was excellent and they look great. Thank you so much

[Thumbs up]


Installed 2 tire/wheels on 04/07/16 have towed 100 miles to break-in tires
Pulling resistance seems to be lower trailer tracks very stable The only thing that
maybe an issue is needing to balance tires for a less bumpy ride I am going to
try to find a tire store that can balance 12" tires Also this tire looks like a real
tire unlike Bias Ply tires and the tread depth is 6/32" which should do well in
the rain possibly less hydroplaning the bias ply Other than that tire/wheel
is very well made product They should balance where tire/wheel is mounted
before offering for retail sale

Thank You

Tires wear like iron
EDGAR K - 04/11/2017


First time buyer, etrailer made this so easy from research via the reviews(Q&A) to easy purchase, and shipping. The tires arrived quickly in great shape. Had them mounted within the hour.
Very satisfied and will update after a long trip. Thank you etrailer!


Great looking tire with a high load range (D), Made in the USA Wheels with heavy duty Brass Shaft Valve Stems, these will hopefully give me many trouble free miles compared to the load range B tires that kept de-laminating on me.

Customer Service was responsive and the order shipped promptly.

Still going strong, tires have help up remarkably well under the load of my heavy boat over many a hot summer mile.
Charlie R - 07/14/2016


Great people to work with. Fast delivery and just what I was hoping they would be. Price was very fair. They are so far doing a great job. Thanks


Trailer seems to pull better thanks to the new addition of these radial tires and rims.

  • Recommended Black Wheels and Larger Tires to Replace 4.80x12 Tires
    Jumping from 12 inch wheels to 14 inch wheels is a large jump. You'd me moving from a diameter of 20.5 inches to about 26.3 inches. If you have the room, that will work but you do need to have about 4 inches above your tire for proper suspension movement (deflection). My recommendation is to stay with your 12 inch wheels and use the Kenda Karrier ST145/R12 Radial Trailer Tire with 12" Black Mod Wheel - 5 on 4-1/2 - LR D # AM35354. This does give you a slightly higher load rating, but...

  • Does Bigger Trailer Mean Faster Speed
    Trailer tires are only rated to go 65 miles per hour unless indicated. Trailer tires are built with a thicker sidewall, to handle vertical loads, that get hot enough to fail when you exceed 65 miles per hour.

  • Looking for 12 Inch Wheel/Tire Combo With High Speed Rating Suited to Hot Temperatures
    For a 12 inch wheel/tire combo, I'd recommend the Kenda Karrier ST145/R12 tire on a 12 inch powder coated steel wheel, part # AM35354. This is a radial tire that will run cooler than a bias ply at highway speeds, however the tire is rated for a maximum speed of 65 mph.

  • Replacement 145/12 Trailer Tires and Wheel for Rockwood Freedom Pop Up
    Wheel diameter is not measured using the overall diameter. It is actually the diameter inside where the tire sits. You have 12 inch wheels; the tire size also indicates this. Tire and wheel combo # AM35354 will fit but you will want the tire construction type and load range to be the same for all of the tires on the trailer. If you are replacing all of them then it isn't an issue provided all of the news ones are the same type and load range. But if you are just replacing 1 tire then it...

    The most common 5-bolt trailer wheel lug pattern is 5-on-4-1/2, but since there are actually four different 5-lug patterns in use you will want to refer to the linked article for help determining which you have. You will also want to verify the size and load range rating of the tires you have installed on the trailer to ensure you select a match.

  • Does Pilot Diameter of Replacement Wheel Need to Match Original Wheel
    The answer to your question will depend on whether your wheels are hub centric or lug centric. Hub centric wheels center on the hub using the hub bore and lug centric wheels center on the hub using lug nuts. Hub-centric wheels typically use wheel bolts rather than lug nuts to attach to the hub. Hub centric wheels are more commonly found on import vehicles and are not too common for use on trailers. If your wheels are hub centric, you would want new wheels with the same pilot hole diameter...

  • Does Kenda Karrier ST145/R12 Trailer Tire & 12 Inch Black Mod Wheel AM35354 Come Balanced
    The Kenda Karrier ST145/R12 Radial Trailer Tire with 12" Black Mod Wheel # AM35354 does not come balanced, nor does any trailer tire and wheel. While you can have them balanced if you'd like to, it really isn't necessary for performance so long as your tow vehicle tires are balanced. The reason for that is the trailer is simply tracking as opposed to being responsible for steering/turning. The tires and suspension on the trailer won't be affected at all by not being perfectly balanced,...

  • Is There Advantage to Larger Trailer Wheel and Tire Size ST145R12 over 8 inch Wheel Size
    The ST145R12 like # AM35354 is a 3 inch taller wheel and tire that what you have which typically means a smoother ride quality and often means a higher speed rating on the tire as well. Also the larger the wheel and tire size the higher the weight capacity as well. Normally people want to go with a larger wheel size whenever possible and not typically do they want to go smaller. If the trailer works well with the 12 inch wheel size I would not recommend going with a smaller size for any reason.

  • Recommended 12 Inch Wheels and Tires for 2007 Stinger Motorcycle Trailer
    The first thing you will need to do is find the bolt pattern on your trailer wheels. From what I have found, you have a 5 on 4-1/2 bolt pattern on your current wheels, but you will want to confirm this. The other thing you are going to need to do is check your clearance. It looks like this trailer has fenders that will need to be removed if you add a 12" tire because of the height difference. You will also want to make sure that you have at least 2" of clearance between the tire and frame...

  • Will Kenda Karrier ST145/R12 Trailer Tire & Wheel Replace 155/80R12 Tires
    Yes, if you'd like to replace your 155/80R12 tires - which seem to be a passenger tire size - you can do so with the Kenda Karrier ST145/R12 Radial Trailer Tire with 12" Black Mod Wheel - 5 on 4-1/2 - LR D # AM35354. It shouldn't be just a spare though, as you'd need to replace both tires and wheels at the same time as you can't use two different sized trailer tires. They will work good as replacements when needed though as the sizes are almost exactly the same, with the # AM35354 being...

The # AM35354 has a ST145/R12 tire on it so while it would be a great choice for a trailer tire, it would not be exactly what you said you wanted. For a wheel and tire that has a 5.30-12 you would want the # AM30859 instead. Now the # AM35354 that you referenced is a very similar size and is a radial tire so it would be a better setup for you.

  • Will a 145/80-12 Trailer Tire Fit in Place of a 4.80-12 Trailer Tire
    All of the 4.80-12 trailer tires are going to be bias ply tires but I have good news for you. A 145/80-12 trailer tire will fit the same size wheel width as the 4.80-12. But the 145 will be approximately 0.8 inches wider and 0.8 inches taller than the 4.80-12 tires. So you need to make sure that there is enough space between the existing tires and the trailer all around the tire to use the slightly larger size. For a radial 145/80-12 you can use # AM10130. It is rated for 1,220 pounds...

    The tire size 145/80-12 does fit on the same rim size as what your 4.80-12 fits on. For that we have the # AM10140 which is a radial trailer tire size. This would basically be just .8 inches taller overall so it would fit and work well.

  • Is 12 inch Trailer Wheel and Tire Decent Option for Trailer
    So the current size you have isn't a standard trailer tire size which is why you are having a hard time finding replacements for it. 12 inch wheel and tires on trailers are solid options and I wouldn't hesitate to go that route. The closest trailer tire size to what you have now is the size 145/80-12 like with the part # AM35354 for a wheel and tire or part # AM10130 for just a tire.

    The difference in section width between a 5.30-12 and a 145/12 is just 0.1 inches. Only half of that is applied towards the trailer. On wheel and tire combo # AM35354 the wheel is a black mod wheel with a zero offset meaning that the mounting surface of the wheel is in the dead center equal distance from either sidewall. Both tire sizes fit the same wheel size so if you just wanted to go to radial tires then you could use # AM10130 for a load range D rated for 1,220 pounds at 65 psi. Or...

You want at least 3 inches between the tread and fender and an inch between the sidewall to the inside of the wheel well.
