Not another tire size thread... or is it? JKU 35" w/ Teraflex 3"

Before the LMGTFY responses pile up, I have been reading up on everyone's opinions on tires, lifts, and geometry... It has been helpful. This is specific to the configuration I am setting up and the use case for my Jeep.

After next weekend, I will be riding on a 3" Teraflex lift with Bilstein 5100's. This is the lift with replacement front lower and rear upper control arms to improve geometry. Needless to day, I am excited to see it on there!

I've been hoping to keep the wheels I have (18"x7.5"). They are a matte black painted Sahara (Altitude) from 2012 and I like the look.

I drove this lift with 35's on a friend's JKU and I like the ride, so that is the direction I am leaning.

Given these constraints, does anyone have any specific experience with 35's on 18x7.5's? I'd like to stay at $240 or less per tire (need 5). I am partial to Discount Tire as the local shop has taken very good care of my wife and I for years including the one time we didn't buy tires from them. Any experience with their private label brands?

My usage: On a scale of Rubicon trail to Tillamook, I am more Tillamook. I've decided to go down the overlanding route with my build out as my wife and I like to explore more than crawl (though I wouldn't shy away from an adventure every once in a while)

Thanks in advance for your opinions and sharing your experience!

We ran 35s and factory 17s on my wife's last Jeep. Same width wheel and backspace. Some tire shops (discount included) have been known to not mount a 35" on that narrow of a wheel. It's a little narrower than the tire manufacturers suggest. I got our Duratracs from the Goodyear store and they mounted them.

The duratracs were a great tire for us. We put Cooper STT Pros on her new one and really like them too. Both are an MT but ride great IMO.

I think you may want to up your budget since you're staying with an 18" wheel. Personally I would drop down to 17" for several reasons, price being one of them. For instance a 35/12.5/18 Duratrac is $328 on DT's website, where a 17" is $296.

Keep a few things in mind:
  • You'll have to decrease your backspace with a wheel spacer, the factory 6.25" BS won't work with a 35". Shoot for 4.5" BS for a 12.5" wide tire
  • Remove the rotor retaining clips when you add the spacer, most are not designed to work with them.
  • You'll likely have to trim the front plastic air dam if you're still running a stock bumper.
  • You'll most likely exceed the weight spec for the tailgate and will need a aftermarket bumper or hinge to hold your spare.

Good luck!!

Here’s 295/70r18 st pro on stock sahara wheels, about 1/4” shorter than 35s but you cannot tell the difference when parked side by side. Great on and off road. Actually the website is acting wonky so pics but still a great tire and specd for a 7.5” wide rim

Thank you for sharing your experience! The STT's are 'good' for road noise? Good being a relative term. I'm hoping to avoid a hum that wakes the dead and puts me to sleep.

If the manufacturer specifies that a tire is designed for a 7.5" wide wheel, is that really what the tire shops are looking at, or is it percentage over factory?

Good checklist. I am putting a 3" lift on and have some good spacers lined up. Also, I installed Teraflex's hinged carrier upgrade (BEEFY) along with the spare tire relocation bracket. I seated the wheel lugs in the 35" set of holes to gain the required bumper clearance. I have a new bumper installed up front so no more plastic air dam!

Lastly, good tip on the retainer brackets. I was watching a lesson on YouTube University and they guy showed how the retaining clips get in the way of wheel spacers. Good Call!

The Cooper's have been on my radar.

What do you all think of the Discoverer ST Maxx for overland/highway usage?

Then there's the Atturo and Pathfinders which are Discount's house brands.

Thoughts on those? I guess one other thing I would like to hear about are any opinions that people may have regarding air-down if needed on any of these choices.

The Cooper's are a solid choice. I'd rank them second behind Toyo/Nitto at this time in terms of overall quality. As for the Atturo's, I wouldn't even consider them as they are very low quality. Remember, tires are one of those things that you usually get what you pay for. Buy once, cry once.

We've put 14k on the wife's STT Pro, and love them so far. To me they are the perfect amount of hum, let you know it's there but not too loud. On my Jeep I'm replacing the Toyo MTs with the STT Pro in a few weeks. I've put 80k on them and they've been good, but they are heavy and I want a lighter option this time around.

Most of our Jeeping is overland but we do the rocks a few times a year too. In our experience there is no instance another drivers AT has performed better than my MTs.

Here's a couple of pics from last week in the Ouachita National Forest, her STT Pro next to my bald Toyos Both in the 37" flavor.







EDIT:

And here's her last Jeep with 35s (315/70/17) Duratracs on the factory 17" wheel.

Nice looking rigs!

Did you need spacers on the 35's on stock wheels? If so, what size?

Thanks! We used 1.75" spidertrax spacers to get us to 4.5" backspace.
