KO2 Tires - 305 or 285

Is 285 the biggest you can go on a unlimited? It looks like the 305s are 33.8 inches.

I was told that 33 was the biggest you could go without rubbing.

Any thoughts on this would be very much appreciated.

from what I have read on this forum, even 33's have the possibility of rubbing at full lock or when stuffed depending on stock rims and no lift.

If you're not running at least a 3" suspension and 1" body lift the 33" tires will rub. Also, you'll want, ideally, an 8" wheel with 3.75" - 4.25" backspace. Without these things, a 31" tire is the biggest you can run on a stock TJ/LJ.

Keep in mind that BFGs tend to run short. I doubt they are a true 33.8".

Don't get me wrong, they are good tires. I would likely just go with the 285s due to rubbing and width.

With "after market" wheels and that backspace, you'll be fine, it's exactly what I plan on doing.

I ended up going with 17x9 with 4.5"bs also, with out a lift the 32-33" should be OK, I started out with the 33" KO2, but with a 2.5" lift they did not look right

I have 285 Duratracs. Lock to Lock I got minor front swaybar and rear control arm. This was just street driving, no trails.



This is before the spacers to where the rear tire would just come off the ground




Threw spacers on it, instead of rubbing on the suspension it would rub on the fenders (with other discussions I have seen the pics). Anytime you move the outside edge of the tire outward, you run the better chance of hitting the fenders. Flat fenders of course would take care of that, but I'm not a fan of them.
