tire size
 

I have a 2011 silverado crew cab with Z71 and a 2" leveling kit.

I am trying to find some tires with a little more aggressive tread to them. But, the stock 265-65R18 tire size is pretty difficult to find a decent tread tire. What size tires can I use with keeping the factory rims to get into a more aggressive tread.

I am thinking something like cooper STT for reference.

Thanks,
Chris

bump.

The leveling kit should have a max. tire size recommendation. But it's probably 285's.
