Can I fit 22's on stock suspension?
 

I got an 05 mc LT

2" lift

you can with rubberband 245/30/22 anything bigger u will need a lift.

Or you can go smaller I got 235/30/22 on mine and they slid on with out a problem. But if you go 235 keep some extra cash laying around because it's a real rubberband tire

the 22's I had where way to wide 265/35/22

gonna go with some 245/35/20's on some different rims
