Hello Everyone! I have a 1997 GMC Suburban K1500 4x4 with a 4.5 inch lift and 2 inch wheel spacers. It has stock 16 inch wheels. What is the largest size tire (height and width) that I could fit under my truck and on the 16 inch wheels without rubbing, meaning without having to do any trimming on the frame or fenders, etc. ?? Thank you very much!
You’ll get more answers on a 4x4 forum.

I would call around to a few different 4wd shops that specialize in lifted trucks and custom wheels and tires and ask them, you may find a better selection of tires even going with a 17" wheel, they might also has some pull offs that they could test fit your vehicle…
Just keep a close eye out on your ball joints and bearings, that is a lot of weight being moved outwards… It cost to look cool…
I have a question.
Why?

Stock wheels are 16x8, you won’t get very large tires on those. Maybe 265/75 x 16. Stock is 245/75x16.
A guy has 315/75 on 16x8’s on a Tacoma on another forum I am on… Looks good…
I have installed 285/75 on 16x8’s… You can run a 295/50 on a 15x8 with no issues…
Well, one can put all kinds of tires on it. Biggest I can find on tables of ‘max’ sizes is 275. So 285, ok. 315? I wouldn’t want to try cornering with them.
The 315’s are probable LT 10ply load range E tires, but yeah, 315’s are pushing it a little bit… lol
