Tires (the weakest link)

Method makes some higher rated rims in LT tire sizes. 245/70r19.5 will fit the GM, but you may need tie back the fender liner up front or use a leveling kit to prevent rub at full lock. My Vision rims worked well, but I did not have a GM. American Force also makes high weight rated 19.5" rims - they have many patterns but a price that rivals or exceeds Rickson.

I would be fine with modifying the fender, but I'd rather not mess with the suspension/steering geometry (if I can help it). I wonder how often rub at full lock will actually be an issue anyway. I suppose it'd just be annoying when I forget and try a K turn. I am only seeing wheels on Method's site not tires. I looked at American Force, but they only seem to have 19.5x7.5 and looks like they have the same offset as Visions, so they might rub. I could likely trim the fender and get rid of the rub, but I'd almost certainly save some $$ and go with the visions if I am ready to trim.

I pointed to Method to get higher rated rims in 16-20" to go with some of the LT tires rated over 4000 lbs. The GM OEM rim ratings are typically less, so going to tires that exceed the rim capacity may help with ride, but will not give you more capacity than the lowest rated component.

In my case, I was running a SRW with 8000 lbs or rear axle weight which is why I went the 4500 lb rated Vision rims but then I went 245 H-rated tires that were over 5000 lbs to get the handling and tire strength I wanted.

You do not need to trim the metal fenders on the GM to fit 245/70r19.5 tires, but the plastic fender liner may interfere unless worked back a little.
