Duratracs 285/70/17 vs 265/70/17

I have 2012 jk rubicon with new set of aev pintlers, trying to decide on size, load c rating vs d rating, and if 285s Duratracs will fit with no rubbing issues with stock suspension, and will spare tire work with stock tire carrier.

I think this has been covered pretty extensively here. The short answer is yes 285's will rub with any kind of offroad flexing and when at full turn on the steering wheel. The spare will also require new bump stops. This is the reason why I am going with the 265s when I get my DTs because I am never getting a lift on mine for various reasons but mostly because my wife can barely get into it as it is with the baby.

32.8" but most brands are right around 32" once mounted.

The only question I believe that does not yet have a response is regarding the stock tire carrier. A 285 will fit there no problem. Because the backspacing of your new pintlers, your tires will sit out further from the rear gate and stock bump stops. No need to worry about the rear hinges with that size/weight tire.

No.

You cannot run a 295 on a 17" wheel.

If your staying with 17" wheels and want a 33" tire then your choices are 285/70/17 32.8" or 305/70/17 34". I would not recommend moving up in wheel size. What looks best is completely up to you, I can help with everything else.

I love my 285 70 17 give it a mean enough stand for a mall crawler. Only lost about a mile to the gallon. Mine are 32" on the nose.

I do have after market wheels with 4.5 backspacing. Something rubs if I turn the wheel all the way to the right and back up? Think it might be catching the air dam.

Great tires great look

I don't understand what you mean. People run 305s on 17s all the time, so why couldn't you do the smaller 295s?

Sorry about the confusion, my go to site did not show any available options for 295 on a 17" wheel however it looks like you can in fact do that. I learn something every day.

Gotcha'

Yeah there are not many 295 options. It's sort of an odd size.

I've reviewed about six different AT and MT sets in a C load range and now run 305/70/16 Duratracs which are a load range E. If your concerned about the load ranges this may help. I think they ride just as comfortably and I've not experienced any roughness at all sometimes associated with heavier load ranges.

A little stiffer and rougher. I can feel more of the road. But not bad. I love it.
I did not have rubicon Had stock 255 75 17.

The Duratracs are a fairly soft rubber, which gives them a nice quiet ride for such an aggressive tire. They also wear faster, and you'll want to rotate them at least every oil change. I've gone through 4 sets on 3 different vehicles. My last set on the work truck lasted 1.5 years and about 25,000 miles. Yup...

The ride is influenced greatly by how much air pressure you run in your tires, so you can't really stay they'll be stiffer than his OEM tires if he ran his OEMs at 40psi and runs the DuraTracs at 30psi.

So the 285/70/17 (Duratracs) are not too heavy for the stock carrier and hinges ??!!
I read here somewhere that they were.

I have been studying up on my tire knowledge and have covered alot of ground in last month or two but what are the ratings all about? Such as "c" or "d"?

Those are the sidewall stiffness rating which is determined by the number of plys in the tire
C=6ply
D=8ply
E=10ply

You'd put E range on a heavy pickup, so they are pretty stiff on a jeep(but many ppl still run them and love them). I run C and love them, but ill get D for my next set

Went with 265/70R17 Duratracs on my 2013 Crush JKUR.

From what I can tell, the only real upside to 285s (apart from looks) is 1/2" of ground clearance, which is not that great.

The downside is potential rubbing (leading to spacers, flat fenders or a lift kit), decreased fuel mileage, higher center of gravity, increased unsprung weight etc. Also worried about total height if I want a roof cargo rack -- need to fit in the garage.

The 265s look great and ride well. Fuel mileage (and everything else) is better than the stock KMs. So for me the 265s were a hassle-free option.

I went with 265 as well. You forgot to mention the 285 are also higher load range so rougher ride. The only thing I'm.not happy with yet is the straight line tracking. I'm playing with toe in but don't have it where in happy yet. However the tires stick incredibly well wet and dry and look awesome.in my opinion
