I have a leveling lift 2.5 in.. on my 1500 extended cab silverado 4x4.. right now I have factory tires, 265 -r70- 17 .... what's the biggest size of tires I can get , before it starts to rub , or damage the suspension.....on 17 inch rims .... some one SAID 32x12.50.. I don't know about that?? Cause the 265s have a only 2.5 - 3 of inches of space between the front and back fenders....... need advice from the real experts.. thanks ... rik

285/70R17, easiest to fit
295/70R17, nice trade off between width and height
305/70R17, close to a 34" tire for stuffed look. Depending on tire design, may rub passenger bolt coming out of the frame (can trim with no ill effects)

this is 305/70/17

Highly recommend a 285/70/17. If you had a 1.5 inch body lift a 305 would work but most experience rubbing issues when flexing. The pics below are from when my truck had a 2 inch front lift and 2 inch rear lift with 285 tires and 9 inch wheels.

On my 3/4 ton suburban, I put on 305/65r17 BFG's (a more rare, unique size).

I'd upload but my files are too large. :(
