Maximum Wheel & Tire size for GMT400 trucks


Recommended Posts

Guys,

 

I recently acquired a set of 2016 Silverado 18" wheels from a friend...and would like to have these on my 1997 K1500.

 

The stock size for the wheels is 265/65R18 which I know will fit under my truck...but I am wondering what the maximum tires size would be for an 18" wheel on the GMT400s just in case I decided to get larger A/T tires.

I also got a set of 2016 Silverado 18" rims and put LT275/65R18 tires on them and I have had 0 issues.  You might get away with 285 width, but that's questionable.  The guy at the tire shop told me the LT275/70R18 would not fit.
