Trailer Tire Recommendation to Replace 155/80-13

Question

Question:

I asked earlier about P155/80R13 replacement tires. Could the wear on the inner edge be caused from being a car tire and not a trailer tire?

The tire size you have is not designed for use on a trailer as it's a passenger vehicle tire size. That's actually what the "P" in the tire size references. You want a tire size that starts with ST which means it's for a trailer application. The closest trailer tire size is the size ST185/80-13 which for that I recommend the Westlake part # LHWL101 which is a radial tire with a higher speed rating and a warranty that includes roadside assistance and tire replacement. This tire also has a great tread design that will give you great traction in wet and dry conditions.

The ST tires have sidewalls that are reinforced for vertical loads like what trailers often encounter.

When the inside tread on your front tires is wearing faster than the center or the outside edge, the problem is likely a "camber" problem or that the trailer is overloaded which is causing the axle to flex out. That said, since you were using a vehicle tire on your trailer that could partially contribute to the problem as well. It's probably a good idea to verify you aren't exceeding the weight capacity of your trailer and also have the alignment of the trailer checked as well.

A 5.30 X 12C tire is going to be your best replacement. If you need the 4 on 4 inch bolt pattern #AM30780 is a good option, or #AM30820 for the 5 on 4-1/2 inch bolt pattern. These both have the wheel and tire included, which you'll need, since…

If you go up to 175/80-13 sized tires, like # they will be about 1-1/2 inches larger in diameter and about 1/2 inch wider. You want at least 3 inches between the tread and fender and an inch between the sidewall to the inside of the wheel well. If…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

As long as you have the needed wheel well and trailer frame clearance, there is no reason that you couldn't go to a larger tire size from your existing 5.30-12 tires. The next size up from what you have is going to be with an ST175/80-13 size…
