I have a 2013 Ram 2500 Leveling kit running General Grabber MT3 35"x12.5x17R. I'm VERY interested in the Nitto Ridge Grappler due to all the reviews and what I will be using my truck for. My issue is this. The tires recommended for my truck have an 80psi max. The Ridge Grapplers have a 65psi max. Now here's the thing the Ridge grapplers are still a load rating E tire with 3195lbs rating which is the same Grabbers 'm running now. I will be towing a 35' toy hauler with a Harley in the back. When I get to where I'm going it's going to be a lot of driving on wet rainy pavement and some times in a muddy environment. The tire shops say Nitto won't warranty the tire if I use them due to psi issue. I was told that I need a 121Q load index rated tire. I really don't care about the warranty to be honest.
Does psi of tire really matter if it has an E rating and load capability of 3195lbs when my Grabbers have the same performed fine? Also, does anyone know a hybrid or mud tire that is f rated load index or has an 80 psi max inflation? I'm not trying to buy 20" rims to get a 35" tire with an f rated load index and 80 psi.
Do any of you run 35x 12.5x17 ridge grapplers on a 2500 or up and do any type of towing? Thanks in advance. Oh ya one shop mentioned something about the TPS having to do with it. If that just means that light stays on I can deal with that. It's been on since I bought the truck last year.
