need better tires

Hi I have a 2013 JGC overland summit and it is a one month old, amazing vehicle. But it came with 20 inch wheels and GY Fortura tires and they just aren't cutting it where I live. We have a mile of rocky, gravel, dirt road to get home and while the jeep does much better on these roads due to the awesome tracking and suspension, I want better traction - the tires are the issue, and some of the big rocks/ruts make me nervous with the low profile sidewall of those tires.

I want to put on 18 wheels and more aggressive tires for rocks/gravel/dirt. And we get lotsa mud in rain. Is there anyone who has done this before? Need some advice I guess. Jeep says 265/60/R18, but my jeep service thought 275/65/R18 ought to fit?

Thanks,

Pat

Sounds to me like you need a commercial traction tire such as the Cooper Discoverer ST MAXX. Something with bite, but also cut resistant tread compound. Although, I don't know what's available in those wheel sizes.

Personally I'd do 265/70s on some 17" wheels if it was me.

Would a 16" wheel fit? I think that a 16" wheel and R16 tire would be better, if a 16" wheel will clear your brakes. Look for a load C tire. There are a few load C tires in R16 sizes. If you can't fit a 16" wheel, then a 17" wheel.

For tire, I recommend Cooper AT3. I use them every week in conditions similar to what you describe. They are doing great on steep rocky roads, steep muddy roads, muddy creek bed, and are excellent on highway.

Cooper AT3 is aggressive enough for mild to moderate off road, and mild enough to be excellent on highway.

I think the problem is the size of the brakes and calipers, 18 " is the smallest rim you can put on that overland. I do like the cooper and I saw a BFG fairly aggressive tread in costco the other day but there does not seem to be a large choice, so still looking. Thanks for the advice btw.
