How wide of tire can I run?

[CJ Dietrich]

Got a question for y'all. I have a 95 Sierra short bed step side and I want to know what size tire I should run. I don't like the look of the 235/75r15's I am using. I want to keep the rally 15's but I want to smaller side wall and a wider tire for a more aggressive look. I also plan lowering the truck 5 inches all around. If somebody could give some input that would be great!

Mine’s got 315/20s out back and 285/20s up front. No rubbing or anything like that but mine is also only leveled in the back, not lowered up front

275/60-15's on a 4/6 drop.

I've run 275-60-15 on all my trucks, stock height though.

I ran 275/60/15s slightly lowered, then had 275/55/17s on 9.5” rim out back. 255/55s up front, 8” rim.

I’ve ran as high as a 32x11.5x15 and 275-60-15 using stock wheels.

for what you want a 275/60/15 or 295/50/15 although 295s will be really too wide for the stock 15x7 wheel.
I wouldn’t know what to run on a 5 inch lowering maybe a 255//60/15 ? Those are wide tires also so wheel offset/backspace will make a difference.
I’m would go with a 15x8 rally wheel as the 255 and 275 will stretch out better on a 8 inch wide wheel if you’re gonna stick close to stock on height.
