Replacement Trailer Tires

Friday, May 4, 2012 by Hunter Leffel

Recently, we added the Power King Towmax STR to our trailer tire line-up that also includes the Goodyear Marathon Radial. By adding the Towmax STR tire, we now have more sizes and load ratings available for customers looking for Trailer Service tires.
 

Both tires are similar in their exterior features. A rounded shoulder with an internal polyester cord body provides a smooth and stable ride. Circumferential grooves provide ample water evacuation. Constant and consistent contact with the road is achieved through the solid center rib and symmetric tread design.

Both the Goodyear Marathon Radial and Power King Towmax STR are radial construction. We don't offer bias ply lines. Additionally, Tire Rack only offers modern tire sizing in the form "ST205/75R15."  If you have an older tire with a classic size such as 6.50-15, you'll need to convert to a modern size first. To make the conversion simple, take a look at this table.

Special purpose trailer tires aren't intended to be used on cars or light trucks and are not UTQG rated. Your trailer will be more stable and pull better on tires designed specifically for trailer use. Since Special Trailer tires are constructed with heavier duty materials, they are tougher than typical passenger vehicle tires. This is a plus because trailer suspension systems are generally stiffer and less sophisticated than automotive suspension systems. For more information on a trailer tire's design, read "Trailer Tires vs. Passenger Vehicle Tires."

I'm having trouble finding a replacement trailer tire. Printed on one tire is 145R13 and the other 155R13. I can't find these specific tires. Is there an equivilant?

Chris,
155R13 is the same as 155/80R13. We do have a couple car tire options in that size at tirerack.com

I have a 5th wheel toy hauler and there are times when I will be hauling off pavement..never the really rough stuff but 20 miles on gravel roads is not unheard of.
I want the best tire possible...changing tires has a very very low fun factor.

Hi Gage,
The trailer tires covered in this blog are the only options we have for dedicated trailer service. Youcould possibly explore LT tires, but that may dependent on the size you need.

I have a trailer with tires that I believe will not be capable of towing the load that I need. Printed on the sidewall of the trailer tires is 4.80 - 8.00 and B Load Range at 590 lbs per tire. My load will roughly be 1500lbs (It's a two wheel trailer btw).

Hi Scott,
We are having trouble finding any reference to that tire size. If you could email a picture to me at hunter@tirerack.com I will try move forward with a suggestion.
