Looking to upgrade the tires on my JKU

My 2010 JKU Sahara is completely stock. I'm looking at upgrading from my stock 255/70/18 tires to an aggressive looking 33-34" tire. I do about 95% on-road and about 5% light off-road driving. I have done a lot of researching but it has only made me more confused.

Right now it looks like it's between it's between the 275/70/18 BFG T/A KOs and the Wrangler Duratracs. Supposedly that size measures out to 33.2".

There is also a 285/70/17 for both tires, but online it says they only measure 32.8" and are actually a little more expensive.

I will be adding a lift or leveling kit and spacers if necessary.

So my question is should I get 17" rims or stick to the 18"? I might get new rims anyway, just wondering if I should get a different size. And does anyone have any pictures with these tires? Which tire is better for my situation? What do y'all recommend?

I was in a similar situation to you and went with the BFG AT in size 285/70/17. My wheels are AEV Savegre. Pricey, but I love them.

I'm exceedingly pleased with this setup so far. The tires have great highway manners in terms of handling and noise in a variety of weather. My 'wheeling' has been limited to some dirt and gravel road kinda stuff so far, but they've seemed nice and grippy no matter the conditions.

I have no lift or spacers at this time. When I wear out this set out, I may jump to the same tires in the 315 size, in which case I'll look at a leveling kit. (I may actually go the leveling route regardless at some point.)

Same Questions I had last year, I have a Sahara.

I ended up with 285/70/17 km2's - no lift required, I put a 3/4" puck in the front for the heck of it but not needed.

I ended up putting 1.5" rock krawler springs on and love the set up but now I can not wait for the tires to wear out so I can buy bigger tires.

Lucky for me the km2's are wearing out FAST.

I like them but they really are wearing out to fast for the price. I ride mostly roads but do off-road and they are great on both.

I am now dividing between 295/70/17 and 35's..... The new decision now needs to be decided.

I's stick to smaller rim sizes... tires are cheaper and the chunkier sidewalls look better on a Jeep in my opinion. If winter conditions are a factor to you the duratracs are a much better tire than the BFG's BUT the BFG's will last longer, Duratracs also clean out better in muddy conditions.

I don't know which BFG's you're referring to but my BFG M/T's didn't last at ALL. I'm changing them out at 25k and I rotated them often... I admit I did a four tire rotation but they shouldn't have worn down that fast.

The 17's are about 6 pounds lighter than the 18 inch tires you specified. I know, that seems counter intuitive but part of it is the 18's are load range E and the 17's are D's. The 17 inch wheels will be lighter to. If money is not a problem, find a light 17 inch wheel and put on the 285's. You won't miss the 3/8 of an inch in height.

Or put on 15 inch wheels, save $500 bucks over the cost of the 17's and get an even lighter combo, lighter than your stock set up.

I'm not sure with the Sahara wheels but going to a bigger tire might cause rubbing so spacers or new wheels might be in order anyway.

Either brand is good. BFG AT's are a bit better on the street and the Duratracs a bit better off road. Both are great tires, however.
