First set of new tires soon….

While I have actually been a bit impressed with the wear and function of the fleet Goodyear Territory MT’s that came with the truck, I need a bit more aggressive tire since the truck is used on our farm. I’d like to run a bit wider tire but don’t know what I can run on the stock 18” wheels w/o rubbing. Anyone running 33 12.50’s? Thinking of something like the Toyo MT. Thoughts?

Is this for a 2500? Some people have been able to fit 37s on them: https://www.chevyzr2.com/threads/hd-zr2-tire-size.1761/

No, 1500. Thanks

Ah, this ended up in the HD section by mistake.

I haven’t heard of anyone running 33x12.5s specifically but AXE has a good thread about fitting 295/70s https://www.chevyzr2.com/threads/method-305-nv-toyo-oc-rt-trail.623/#post-10728
And some guys are able to fit 285/75s with some trimming. Having stock wheels will help keep the tire in and away from the bumper and fender.

Several people running 285s. They shouldn't need trimming, but every tire is different.

33 x 12.50 seems to be the go to for every trail boss in the area. Which would actually be a larger tire overall with the standard loadout for those trucks.

A 33x12.50 is more like a 32.5” so you would lose a significant amount of height. (ZR2’s have 33.2’s)

The more I’ve dug around the more I enjoy the 305/65 option. Fits. No cutting. Spare still works for the one time you will need it. Works out to about .4” taller (33.6) and much wider. (12”) Tire “proportions” are more ideal to my eye as 70 profiles are a tad “tractor” tire looking IMO.

285/70 is another option at 33.7 but you still have the proportional ratio I’m not crazy about.

Just food for thought.
