Just mounted and balanced. 35x12.5r17 -12 offset. New to the whole Jeep world with a 2018 JKU Sahara. Putting these on before the lift in a few weeks will be strictly on road till then. Jks Jspec 3.5” will be going on. Just wondering what a suitable psi is to run on road till then. Thanks for the help in advance.
It depends on the weight of your vehicle, the width of the wheel, and the width of the tire....along with the sidewall load rating. Ballpark would be under 35 and over 28.
I agree with the other posts. You'll want to test it yourself at different psi. Too many factors,ie, weight, suspension, tire tread, etc. I run my 315x70x17 at between 30 and 32. Also perform the chalk test to keep your tread wear even.
Yes, there are many variables, I used to run MT mud claws and they liked around 22psi on bitumen. Any more and I couldn't steer it, it would just float along in any given direction. The tyre ppl were very unhappy with that pressure but the wear was even (with 110,000 km on them)!
Now I put black bear muddies on and they like around 32 ish..
I run light with two door Rubicon. Just drive it, look at the contact with the road from behind and you'll get the sweet spot
Thats too much lift for that tire but its your jeep and you are new so live and learn from your mistakes. Your first mistake was buying that tire which is E rated for heavy duty trucks. Many new jeep owners make the same mistake. I would expect anywhere from 22-28 psi. Make sure you rotate them about every 3000 miles.

I think the problem is there are not that many C rated 35's to pick from at least in 17's. I have run C, D and E and all have been about equal. I actually like E rated but I know everyone is different and some hate them. for the places that I personally wheel they have not been a hindrance at all, even when I had them on my 2 door. Not sure how much actual lift you get with JKS but AEV recommends 33-35" with their 2.5" and 35's with their 3.5 lifts and 37's with their 4.5 lifts.
You are correct that there is not a great selection of 35's but you can find them and in the 35" range you likely have the greatest selection in a 17" wheel. You can fit 40's on 4" of lift and flat fenders.
So that’s where I’m at right now. 29 psi seems to be working for me. As for the lift, I ordered a Metalcloak GC. 2.5. I think 35s with the jks 3.5 would have been fine. Don’t plan on cutting or changing my flares anytime soon.
If you intend on going more 'extreme' off-road than gravel roads with some bumps and you're still set on not cutting flares then ensure that your bumpstops are set properly to avoid contact with your flares.
