2006 Jeep Wrangler Unlimited 4x4 Tire/Wheel Question

Ok I need your help with this fitment. My customer has a 2006 Jeep Wrangler Unlimted 4x4 with a soft top. The OE tires are 30x9.50R15 tires. His son wants wider and taller tires but the Dad wants an HT type tread because he rides it on the highway and doesn't want the noise.

The 30x9.50R15 basically coverts size wise into a 275/70R15 in a metric tire. So to make it look bigger and wider. I think we'll go with a 255/55R18 and that should do it with no lift kit.

Wheels can be a 18x9.5 around a +30 offset 5 - 114 bolt pattern.

Any thoughts?

Thanks....

Jim

18's on a Jeep???!?!?!? If the father doesn't want the noise I would stick with the 15" wheel and just get an All-Terrain Tire or a All-Season Tire. Probably a 31x10.5R15 For example:

BF Goodrich All-Terrain T/A KO
BF Goodrich Rugged Trail
Bridgestone Dueler A/T Revo
Firestone Destination A/T
There are many more available just pick one your customer likes.

All of these are available in that size. That's what I would do if suspension/body lifts were an option.

30x9.50R15 converts to 245/75R15.... (29.5 x 9.5)

275/70R15 is roughly a 31x10.50 ( a bit wider.)

255/55R18 would be roughly 29x10 - it will visually look smaller (and it is...)

If they really want 18s (ugh in such a small tire) try 265/60R18 which will give you the same size as a 31x10.50.
I'd suggest 16 or 17 inch rims max though or it will be a laughing stock except at the mall...

Big wheels with small tires on a Jeep will make the road ride harder.

I'd stick with the proven 31" tire size look on a stock Jeep. 10.5 x 15.
Unless the customer is after the "pimp your ride look". Fugly

As others mentioned, get a good AT in 31x10.50 for the stock rims.

Ditto on 31x10.5x15's

I have an SE 06' and I put on 31x10.5x15 AT/KO from BFGoodrich. The tires ride hard when aired up at 50 psi and soft when aired down to 36 psi. The tires will last you a long time as well.

Why would anyone with a Wrangler inflate these tires up to 50 psi, even 36 psi is too much.

Hey Marty

What psi do you run your tires on? How much offroad/city driving do you do?

In the beginning, before I knew any better, I did pump up the tires to 50 psi, but I hated the ride. So, now I ride at 36 psi and it rides better in the city. Offroad I go with 28 psi.

With those tires, I'd try about 32-34 regular driving, probably no more than 34, and go down to 15ish for offroad.

I run mine at 28 - 30 on road, 15 - 20 off

I would use about 30 psi on road and 25-20 psi off road with these tires. With my Mt tires, which are bigger, I always use less than 29 psi on road, off road between 25 and 18 psi.
Have fun!
