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! ---

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… ---

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… ![Screenshot 2024-11-20 183942](https://global.discourse-cdn.com/cartalk/original/3X/f/c/fc2c7339d325afd17244ac501c4b277165b32b2a.jpeg) ---

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 ---

Thank you very much! You are going to be limited by the width of the wheel. Check your door for the size of the wheel (and tire). My best guess is the largest tire will be LT265/75R16 ---

It seems like you want to fill the open space in your wheel wells created by your suspension modifications. The short answer is that you can’t do it with the 16” rims. The maximum aspect ratio is 75% and your tire side walls are already that tall. I suggest that you find a shop that specializes in this and buy the tire/rim combination from them. One big advantage is that they will stand behind their selection as long as you go along with it. ---

> [@jtsanders](#): > > The maximum aspect ratio is 75% and your tire side walls are already that tall You can buy a few different 255/85/16’s, in AT and MT tires, and that is what lifted truck guys want, is aggressive treads for off roading and or mall shopping… lol And a 255/85 is still taller and narrower than a 285/75, fills the fender gap up without the extra wideness of the 285… > **[| Tires | Discount Tire](https://www.discounttire.com/fitmentresult/tires/size/255-85-16)** > > Discount Tire BTW Lifted trucks with big aggressive tires are not meant to corner, most of the guys into the off roading drive slower than Chris does… Not the pretty never see even grass from own yard, but off roading guys and gals… ---

It’s best to stay OE. The engineers at GM - or Ford or Honda -knew what they were doing when they designed the thing. ---

And while you may be trying to “upgrade”, or “enhance” performance, and/or be able to brag to your buddies…all you know for sure is the money has been spent. So that you can have a vehicle that probably drives worse in day to day driving, and drinks more gasoline. I see more and more “Carolina Squat” 4x4 trucks in my part of the world. No idea how young men drive those trucks at that awkward angle. My grandmother would have called them “cool fools”. ---

> [@ledhed75](#): > > [bigger tires so] that you can have a vehicle that probably drives worse in day to day driving, and drinks more gasoline. There’s some functional improvements possible w/big tires too. Some 4x4 owners like the big tires b/c they yield more ground clearance. For example my 4x4’s 9 inch rear differential with standard size tires sits pretty close to the ground. ---

> [@ChrisTheTireWhisperer](#): > > or out of mud. You clearly have not been 4 wheeling… Even Ford Chevy and Toyota etc etc puts bigger tires on some/most of the real off road trucks… I for one owned a Power Wagon, and it did better in mud and off roading with bigger AT tires… And it handled great in the curves, Just as good as my car did back in the day… Lifts, bigger (taller) tires give you more ground clearance when going over downed trees and big rocks… ---

I had 265/70R17 tires on a 2 wheel drive Dodge Ram for 12 years, not a huge tire, turns corners as it should. I would think you could use a larger tire on a 4-wheel drive, at least a 33" or 35" tire. The manufacture’s label on the driver’s door reads 225/75R16. I’m considering replacing the door. ---

A friend of mine put a lift on his CRV with 31’s on it, no rub and drove great, he does a lot of fishing and camping and gets around in the off road terrain much better now… [Next page](https://community.cartalk.com/t/largest-possible-tire/198092.md?page=2)
