2012 Grand Cherokee off-road tires recommendation

Hello folks,

I just bought a 2012 Grand Cherokee with all-season tires, I'm planning to go off road and planning to buy all terrain tires (maybe mud terrain), but I'm not sure what tires and especially what size is better.

The current tires are R20. I see a lot of people sell stock Wrangler tires that are also compatible with Grand Cherokee, I like this option because it's relatively cheap, but most of stock Wrangler the tires that people sell are R17-18.

I have the following questions:
- Which off-road tires do you have/recommend for Grand Cherokee (year) and it's size?
- Are R17-18 too low for off road driving on Grand Cherokee? Comparing to R20 the car clearance will be 1-1.5 inch lower with R17-18 and that seems like a big deal for off road.

Thanks!

you are confusing the rim diameter with the tire diameter. few people that off road run 20" rims. Most common are 17" today on the newer jeeps. from there its tires and size. I would stay away from 20s to much rim and very little side wall unless you run 40" tires. Example i only run a 15" rim but the tire is 35" you can have a 20" rim and a 35" what one is taller? they are the same. But off road you air down a 20" rim on a 35" it will be riding the rim. where that 15 and a 35 can go down to 8psi and will about float over rough roads. so there are many ways to do this.

no idea what fits that jeep. If you intend to use them off road getting expensive rims is kinda like lip stick on a pig since they get so beat up in the end.

Got it, yes I was confused with the tire size understanding, but now I understand. Thanks for the clarification!

Will you be in mud quite a bit? If so, you need a MT. Most AT tires will gum up in a flash and then you're stranded. On the other hand, if you'll never see mud, I would avoid MT tires because they're heavier, noisy, and will eat up your fuel economy and handling characteristics in foul on-highway weather.

There are a new breed of tires on the market that some people call "hybrid" tires that are a mix of a MT and AT. That might be a good option for you. Falken A/T3W, Goodforayear Duratrac, Nitto Ridge Grappler, etc. are some examples of these.

@WXman I don't have plans to go specifically to mud, however it may be present somewhere. The options about 'hybrid' tires looks interesting to me, I take a deeper look. Thanks !

I just installed a new sets of BFG KO2 in the size 275/55R20 on my 2011 GrandCherokeeOverland. They are perfect and they look sick!
Initially, I debated on three different manufacturers: BFG KO2, CooperZeonLTZ, and Nitto GrapplerG2. They are all terrain tires, on and as well as a little off road type tires. And I do think I made the best choice!

Off road if you are airing down a lot as we do in sand, sticking with a 70 series aspect ratio tire is best if it fits because you have more sidewall to work with. On my 07 WK-1 Hemi I up sized from 245/65-17 to 245/70-17 which gives me more sidewall because on the beach you have to really air down (ie 12-10 lbs).
For the o.p. I would advise getting 17" rims with all terrain tires in the 245/70-17 size if you can. The larger diameter rims really limit you in off road applications.

^^Well it all depends on how extreme of off-roading you will be doing. Going Jeep Jamboree off-roading type course, I can see the benefit of the smaller diameter wheels/taller sidewalls tires.
