Question Whose running the Duratrac, I have a question

I am 90% sure that I am going with the Duratrac but, I never just wana dive into something thats gonna cost me if I screw it up... I want to go to 33'' on the OE wheels (until I can buy new ones) I'm looking at LT285/70R17 which to the to best of my knowledge will fit. I have a few concerns. First my jeep is currently stock, will there be any rubbing at all with the larger tire, I've heard 33'' will fit w/no lift but I can't shake the feeling the stock bumper is going to get in the way. And Second I do a lot of high way driving, Goodyear claims they are meant as more of an all terrain tire but has anyone experienced any whining while driving at speeds on tarmac? Cause I know it will get annoying, and I'll get a big I told you so from my dad (who will try to make this his point of attack on keeping MY Jeep stock)

As a third thought will there be any problems with the third brake light, visibility or the need to be completely removed?

Thanks for the help!

there will probably be a little rub on your air dam (plastic trim under the front bumper) at full left lock and full right lock. otherwise you should be okay. duratracs are pretty quiet all things considered... they have a little hum to them, but nothing like a mud tire or some of the more aggresive ATs. personally, i love the sound of tires humming on the road. better than music, it's jeep therapy.

one piece of advice though... for the price of 17" duratracs, you could probably buy a set of 4 16" wheels and duratracs. or pretty close. look at the price drop between the two sizes... or even more so with the 15s. which will fit on a JK by the way...

if i may...

are you considering a lift in the future? I run the 315 duratrac, and its barely big enough. I cannot imagine it being smaller.

if your thinking about a lift, get a good 2.5 and the 34.4 duratrac. you will be happy.

if you buy 33s and decide your not satisfied with the look, you have to buy new tires when you buy the lift.

No future lift? duratracs are great 33 in tires.

My plan is to go with the RR 17x9 rims and a Tarflex 2.5 budget boost to maintain as much original ride quality as possible (haven't quite decided but def going 2.5 inches of lift), not sure if I'll need spacers with the RR rims but I will the OE wheels. Something is now telling me I'm gonna need a different set of tire when I change wheels?

Also I just realized the jeeps rim is 75R17 not 70R17 like tire rack was leading me to believe, I don't see the duratrac available in 75R17 except in 245 am I right in this thinking?

285/70-17 is the tire size you mentioned. The stock rim is 7.5" wide.

The 70 and 75 have nothing to do with the rim, it is the aspect ratio, 285 is the section width in mm . The 70 or 75 is the height as a % of the width. (70% of 285 bead to tread top) multiply that by 2 and add wheel size and you have your tire height.

May rub at plastic air dam - I'm not sure - but not the bumper. You could run wheels spacers or a simple leveling kit. I've had 285s, and now 315s. They are very quiet and great on the highway. More wind noise than anything else at speed. They have less buzz than the Rubicon BFG KM stock tires. The 285s are small "33s" and barely bigger than Rubicon OEMs. My 315s measure only 33.6 on the vehicle with 30psi. No problem with 285s on stock carrier. Here's a pic with 285s:

Then here you go! I ran RR rims with Teraflex leveling kit (1.5-2.0 in lift), 285 Duratracs. No need for spacers with RR wheels due to offset:

Hello Ghost....

I have Duratracs LT285/70R17 on stock rims with a 2.5" Teraflex lift. The ride is great on the highway with no problems at all. At full flex I do not have any rub at all. 33" inch tires keep the center of gravity down and my jeep is a daily driver (60 miles round trip to work a day).......

Duratracs are outstanding in the snow.....

Check this thread for 33s on stock: Just ordered 5 x Cooper Discoverer A/T3s

285/70/17 will likely rub, but not definitely. A lift will likely help, but not definitely. Spacers or other wheels will definitely eliminate the rub. Of course, at that point, you might want to go even bigger.

Another must read thread (at least the first post): Largest tire on stock JK? Here's your answer!

The rear tire will put a large amount of pressure on the rear brake light stalk with OEM wheels.

I was going to go with the 2.5'' Teraflex budget boost with the shocks, like yours, doing my research on Quadratec it says that spacers are required with the OE rims. Is that just a recommendation or did you find a way around this problem?

If you're running stock wheels, you'll need spacers to clear the TF lift's sway bar links, I believe.

if I get 33x12.5x15 with an aftermarket wheel with 4.5" and under bs, will I be able to put that on the stock spare tire mount and still have the middle brake light clear the 33 and the mount safely hold the weight of the new tire/wheel?

Yes, your stock tire carrier will support it. I have 285/75R17 's with M/T Side Bitter wheels and have taken it over some very rough rock krawling trails here in Colorado. never had a problem with it.

Duratrac's Love em. Just change them out 3 months ago from Terra Grapplers. I went to a 305/70/16, They're a bit wider than the 285/70/17 Nittos. DT's on the Highway don't like them as much. Dropped my highway mileage down 1 more mpg and just about did away with overdrive, but they're still pretty quiet for an aggressive A/T.
On the trail love em, around town, still love em. Just had my Duratracs in the woods for the first time since I bought them and they SMOKE the old Grapplers in offroad performance.
Can't go wrong with 285/70/17 for a non lifted Jeep. If you're doing alot of highway look into a lighter less aggressive all terrain tire.

For the price, I would recommend you get some nice 15" wheels (like level 8 trackers) with 33x12.50s on there. From discount tire, with all the rebates, you should come in at about $1400 or so. They will also come mounted and balanced, which saves an extra $100 or so. The wheels will stick further out, giving you a more planted ride, slightly improved handling, and no rubbing issues. The weight savings is great as well, weighing in about the same overall as OEM rubicon wheel/tire combo.
