Question:
Our trailer is fitted with two new Tires. One is the Loadstar ST 175/D 13 and the other is a Carlisle ST 175/80013 Sport Tread Replaces B78-13ST. Are these two Tires compatible? I need to buy a third Tire as a spare ....which is the better Tire, the Loadstar or the Carlisle?

Expert Reply:
All other things being equal, it is always preferable to have matching tires on your trailer. Different tire brands may have different tread depths and may wear at different rates due to variances in the formula used in their rubber compound. However, you can use the two different tires if you wish.
As we do not offer the Carlisle tires, I suggest you use a second Kenda Loadstar ST175/80D13, part # AM31233, and keep the Carlisle as your spare.

Hi, Chris. Thanks for the reply above. The tires that I currently have are a 1,300 pound load range. I like the idea of a radial tire. Radials seem more durable for highway towing. The highways in the mountains here in Colorado are pretty unforgiving. Can you recommend a radial to replace my current tires, with the same 13 wheel setup?

Hello. I have a single axle camping trailer. I am thinking of putting some heavier duty tires on it. I currently have ST175/80 D13 tires on it. I understand what the D means Bias Ply. Does the D13 mean that it is a 13 inch wheel? I measured the wheel and its exactly 14 inches in diameter. So how am I finding a discrepancy between the D13 and my actual measurement?
