New Tires advice Class D vs E

Fixn to order new TT tires. 225/75R15 class C came on the TT. TT's GVWR is 8819. At least looking at going with GYM Class D's. Few bucks more I can go with class E's. I know there are opinions out there...

IMHO I feel that anything to do with trailers or tow vehicles you should be trying to get the HIGHEST load rating you can from a tire to fit your wheel.

Needless to say I'd vote for spending the little bit extra now to possibly prevent a blow or and needing to replace a blow tire, or worse wreck truck or trailer!

No sense skimping when you are already buying them...

If you go up to E-range tires, make sure your wheels can go up to 80psi.

60 psi.... Looks like class D's would be the ones, without changing rims too.

During my research on tires, I read a good article about st and lt tires. The interesting part is what the guy called reserve. The e rated tires would just have more reserve than the d rated tire. I'd go with the e if money wasn't an issue.

Go with the E's and run them at 60 psi?

Yea, or if you took it to a scale after you have it geared and know the weight, there are charts on the Internet which would tell you the correct air pressure, which should be at or below 60 psi.

Switched my trail express LR C tires out for Maxxis LR E tires and run them at 70psi cold. I have aluminum rims supplied to forest river by lionshead, I called them about the higher psi, they said just make sure you change the valve stems, I went with the stainless steel.

That's interesting, that's the rims I have and their web site says 60 psi for the load on 15 inch rims...

You wouldn't happen to have a link to that website would you. I couldn't find one.
