37's on 18's?

So ive searched through the multiple pages of wheel and tire setups, but couldnt find if anyone has ever ran 37'' tires on 18'' rims with a 6.5'' lift..................I have my lift kit here waiting along with my wheels for my 2021 Sierra 1500 ........................ HELP PLEASE

If you have Instagram check out ltwmotorsports page, they have done several 1500 Silverado's with 17 inch rims with 37inch tires on probably a 3.5 to 4 inch lift. They have to do some modifications to the wheel liner and mudflap to make it fit. They may also be adjusting the crash rail.

 

I have 35s on a 2.5inch lift and they fit without issue. I did a mudflap delete though. I still have about 1inch of clearance to the liner at full lock. It is all contingent on your backspacing for the wheel though.

 

Anything is possible depending on how much you are willing to modify the truck. I have seen guys running 40s with a 3 inch King set up.
