Tire size question
 

I've got 285/75/16's on my truck right now. I want a wider tire. I don't really get the measurements. I know 16 is the rim but I want to know what number to change to still keep them 33" but wider. They don't have to be exactly 33" and how wide can I go on my stock Chevy rim

what year truck is it goin on? i assume a 99-06 z71?

98 Chevy Z71

Is it leveled or anything?

Its got a 2" block on the back and a 3" leveling kit and 1/4" wheel spacers to keep the tires from rubbing

You could damn near run a 35 on a that truck with a levelin kit. Widest I'd go is a 305/xx/16. Basically a 12.5 wide tire

I've thought about that. I might go with something about 34". I found some tires in 305/70/16 General Grabber AT2's. It says there 12" wide and a little bigger then my tires. Has anyone had these tires and are they any good

I've heard the red letter general grabbers are awesome, but haven't heard much bout the AT2s
