I'll preface this by saying I don't know anything about wheel and tire sizing because I've never owned a pickup before and never swapped rims and tires before for larger ones.

Bought a new 2022 silverado 1500 LT, looking to see what the largest rim size and largest tire size is I can run on stock suspension without modifications. Buddy has a set of 20x10 8x6.5 fuel rims for sale and was wondering if they would fit my truck and what size tire I could put on them ? Thanks !

 

Those will not fit your truck. 1500s are 6 lug not 8. I’m running 22x10s with 285/45/22s and I only scrub in reverse when turning sharp. Installing a leveling kit this weekend to eliminate that. Pics attached below & good luck!

Rubs in reverse at 3/4 turn

22x10s wrapped in 285/45s (equates to roughly 32x11)
