GMC K-3500 Tires — Fitment by Year

I've got a lot of '88 to 2000 K-3500s rolling through here, and the OE fitment is either LT245/75-16 or LT265/75-16 depending on your year and package. Both are load-rated for what that truck's designed to carry, and I keep those sizes on the rack most of the time. Your bolt pattern is 8x165.1, hub bore sits at 116.70mm, and you're looking at a 16-inch rim as the baseline — that's the spec I confirm on every one that comes in.

When you're upgrading or replacing, you've got options. I can match the OE size straight across, or if you want a little more sidewall for rough terrain or a smoother ride on the highway, I'll walk you through what works with your load rating and rim diameter. A lot of K-3500 owners come in wanting something tougher than stock, and I've got all-terrain and heavy-duty options that'll bolt right on. The truck's built for work, so I make sure whatever we mount respects that.

Here's what I do on every install: I run road-force balance on the tires, verify your hub bore and bolt pattern match, torque the lugs to spec, and scan your TPMS while I'm at it. We're bilingual here, walk-ins are welcome, and I've been in Marietta fifteen years doing this work in-house with my crew — no outsourcing, no guessing. You'll talk to the same person who mounted your tires if you've got a question later.

We mount these for folks across Marietta, East Cobb, and Kennesaw. If you need financing, I've got Synchrony for six months on $199 and up, or Acima lease-to-own starting at ten bucks. Walk in at 1585 Roswell Road, call (678) 400-6467, or book online below.
