Should I Follow the Specs for Tire Pressure in Owners Manual of My Trailer or On the Actual Tires

Question

Question:

We’ll be going on a cross country trip and my concern is: the manufacturer Aliner recommended the cold psi be @ 50, but the tire spec label recommends max cold psi @ 65. Tires are loadstar karrier kr35 st185/80r13 load range d. The camper loaded is about 1800 lbs +\- 20lbs. Therefore I have two questions , what should the psi be and will the tires safely carry that load? Thank you!

You'll always want to follow the specs that are listed directly on the tires themselves. It sounds like you've got the Loadstar ST185/80D13 Bias Trailer Tire - Load Range D # AM1ST79, which are designed to be run at 65psi and have a capacity of 1710-lbs per tire; these tires are well rated for a camper that has a GVWR of almost 2000-lbs, so you've got nothing to worry about.

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…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

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 inch whereas the 225/75-15 fits widths that are 5 inch to 6-1/2 inch. The 205 is 27.1 inches tall and the 225 is 28.4…
