New Shoes

[Muskoka Minute]

Well I finally got new Shoes...
BFG KO2's 315/70R17 load range "C"
American Racing Baja 17x9 -12 offset
Without the new tires I'm 628lb over factory spec.
EDIT: With new tires I'm 715lb over factory spec.
Currently set at 34psi

Only have approx 6 miles on them but what a difference.
Still have todo a chalk test to dial them in but WOW what a difference.

It seams to be well planted and very stable.
I'm assuming this is because of the offset and the tire width.

It also seams to ride smoother and take the road bumps better.
Not sure if it's my imagination or not. lol
I'm thinking its the tall side wall and airing down a tad.

What psi is everyone running on road?

That thing would look so much cooler with the original white grill.

Anyways, if it seems smooth to you now, I’m sure whatever psi you’re at is fine. I usually like between 32-35 psi for load range C tires.

Why so angry?

I set my cold PSI 32-34. Seems to make a good on road ride.

35 PSI cold. I'm on a load range E tire.

I was running 36 all the way around on the same tire you have, dropped them back to 32 for around town use and rides much better. Will add a few pounds for road trips to get a little better mileage on the highway.

I bet if you swapped back to the stock grill, you'd be under weight. That thing has to weight at least 200-300#.

I run 25PSI cold... to answer the question.

Did you do a chalk test or just by the feel and the way you like it

I have 285/70/17 Mickey Thompson BAJA ATZ P3's with 36 psi at the moment.

For starters, congratulations on a beautiful rig!

Captain Obvious here, but maybe worth noting that pressure varies with temperature. When temperture increases, so does the pressure. If you chaulk test and find a pressure that works, you'll need to adjust to the environmental changes up and down as necessary. So for example, if you chaulk test in Jan. at 20 degrees and decide that 35 psi works for you, and now May rolls around and its 60 degrees, you'll have to air down to 35 psi because of the ambient temperture having inccressd the pressure in your tires.

Also, uniform wear is all about side wall characteristics of the tire vs the vehicle weight as well as the vehicle weight distribution (front vs back). How you drive the vehicle also plays into wear regardless of pressure.

I run the new Duratrac RT (3 ply with Kevlar sidewall) with an E rating, and I target 22 psi cold on all four for my 2 door and I adjust pressure with the season. I run an E rated tire for durability and would be relucltant to run anything less based on my experience..

There's no best answer to your question but the one that works for you. Try different pressures and watch your wear patterns. Chaulk testing is a good point of reference. Otherwise rotate tires frequently, monitor wear and most importantly smile, cause you're driivin a Jeep!

Will keep an eye on those points.
yes the pressure even changes as you drive due to heat build up on any given day.
Thanks for the input and advice.
Cheers

I ran 31-32psi cold with my 35's on Mopar 17x8.5 wheels before switching to 37's and they were wearing very evenly and rode and handled great. Run 30psi cold on the 37 D's...

715 pounds!?!? How much does that grill weigh???
