Biggest tires for stock 2014 Silverado 1500 Z71 with 18" rims

September 9, 2014

First I apologize, as I'm sure this has been asked many times.

As title says I'm looking for the biggest tire that will fit on my truck without rubbing or requiring any kind of a lift. Truck has 18" wheels, and I'm looking at a set of 275/70/18's. Anyone know if this will fit the bill?

Thanks

I have a 2" levelling kit and I'm wondering if those same tires will fit, I don't think they'll fit with out a levelling kit…

Daly, I have the same setup, 100% stock but want to upsize on my new tires curious what I can go with

2" r.c. level with 275 70 18 bfgt all terrains. no rubbing and I did not have to trim anything.

No levelling kit required to run 275/70R18 no trimming either

Yeah, I think 275/70/18 would fit no problem. Mine has a 2.5" level and there is tons of room.

Appreciate the replies guys. Just wanted to report that I just had 275/70/18's installed on my '14 Silverado 1500 LTZ Z71 today and I will be needing a 2" leveling kit as the Cooper's ATP have minimal rubbing.

I'm still happy with the size and the little extra ground clearance is welcomed.

Thanks again guys!

I really like your truck. I've been trying to figure out what to do to mine that I just bought. Thinking I'm going to do the same setup as you. Do you still like this setup or have you changed it up?

no I have not changed anything since that picture (except taking the chrome side moldings off and put an A/T grille on it). It rides great and looks "right" in my opinion. I only plan on adding a few more things in the next few months hopefully and that is some black 18" wheels, 15 tow mirrors and some bags in the bag for towing. i have towed a couple of vehicles with the level and it was not sagging that bad but if i was driving at night it would have been blinding other drivers esp now that i have HID's.

kinda went on a rant, moral of the story is as far as the suspension goes nothing is changing and I love this setup / truck!
