The closest tire size to your 165SR13 is the Karrier ST175/80R13 Radial Trailer Tire # AM10210. The new tires will be approximately 5/8" taller and 1/2" wider than you current tires when new. You will want to ensure that you can fit the new tires without clearance issues. I generally recommend 1" side wall clearance and 3" vertical clearance for suspension travel.

The next smaller size is the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30790. This would require you to change to a 12" wheel and the one mounted on this particular combination has a 4 on 4" lug pattern. This tire is 1-1/2" shorter and 7/8" narrower than your current 165SR13. It has a weight rating of 1,045lbs per tire.

Great question, William! The Karrier ST225/75R15 #KE63KV is a KR35 while the Karrier ST225/75R15 #AM10303 is a KR03 according to Kenda. There is a slight variation in the tread pattern and from what Kenda says about them it looks like the KR03 is…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

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…

Karrier and Loadstar are two different brand names used by Kenda. There's no difference in quality or function between the two brand names. For a ST175/80-13 Radial trailer tire in load range D, I'd recommend part #AM10210 if you're…

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

Answer 11

Do you by any chance mean 235/80-16 and 235/85-16? Because there isn't a 275 trailer tire size that I have seen. If so then the widths are the same between the two 235 sizes. The difference is overall diameter. The 235/80-16 is 30.9 inches in…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…
