I tell people this all the time and I know a lot of people think I’m talking out my ass, but:
After having 37s for a while, including: driving from coast to coast 5 times; 40,000 miles on the tires; 7,800 lbs fully loaded; Nitro 5.29s; driving the truck hard on road, and on rutted fire roads, and on actual off road trails….
I can conclude that 37s have not been as hard on the truck as people think they’ll be, I guess? If I’m not breaking things (as a direct or indirect result of the 37s), with my heavy ass truck and “rough” driving style, I think most people will be fine if they’re willing to cut fenders and do a cab mount relocate.
I’m not saying the people who warn against it are making things up. I’m just saying I either have a super truck, or 37s are not a huge deal, lol.
