15 inch rims, what's the verdict?

Hey everyone, I have an 08 Rubi Unlimited rolling the stock Rubi 17" rims with some worn, rock rash, 285/70/17 KM2. I want to downgrade to some black 15 rims and slap on some 35" KM2. I'll feel better about thrashing a $200 tire than a $300 tire. Also I would be ditching my Spidertracks(which have been trouble free for about 20,000 miles). Any thoughts? Are the 15" rims problematic? I know I'll be losing my pressure sensor, but how's handling? My jeep has a 2.5" BB from teraflex. Can I see some pictures? And why does a 17" tire cost more than a 15" tire when you are getting more rubber on the 15 incher??

Do it.

You might have to grind a little bit its not that big of a deal.

I run 15x8 cragar soft 8s with 4" of backspacing. I didn't have to grind but the wheels did a little scrubbing on the calipers.

Its a Jeep...its gonna handle like a Jeep no matter what size the wheel IMO.

35/15 Km2s are in stock.

Let me know if I can help with your purchase.

Cool, what I mean about handling is I read on another forum that a member could not run a higher air pressure than 25psi cause it made his jeep handle weird. I forgot the exact terminology he used but it made me wonder. I don't mind grinding at all either.

I am running 15" soft 8's with 35" km2's. I love it! Not squirly at all! No clearance issues either but I'm also running spydertracs.

I run mine at 30-32psi, rotate every 3k and have a perect wear pattern. (or lack of pattern I guess)

I say rock that shit and never look back!!

ive read that with 15 inch rims you just need to make sure the style of rim will clear the breaks some are a little thicker on the inside (best way i can think to put it) like the guy above said it scrubbed his calipers ... also if your going to do a tie rod upgrade some will not fit with a 15inch rim .... I wanted to do the same thing but read about some complications running 15's on the rubi ... so just went with 16's and 35's ... rock krawler tie rod clears everything great and no grinding ... can air down to 8 psi and do just fine wiht 16x8 and 4.25 backspacing wouldnt go much more than that unless your going to a 37 or 40

Pro comps 15x8 w/ 3 3/4" back spacing clear the calipers but you gotta be careful where they put the wheel weights. I run 27psi and the tire wear is good and it rides pretty good too.

I run 15" wheels and it works very well. One issue is if you want to step up to 37's then the tire companies have you very limited. My cost with this rim choice saves money on every tire replacement. It really adds up over time. Check out my trail pics in my signature to see performance off road.

I was going this way, but having second thoughts over a couple issues I just read about.

Rocks have the potential to get stuck in the brakes easier due tight clearance

If you are planning on upgrading to beefier suspension like drag links and tie rods you have the potential of running into problems as well.

If anybody has any thoughts on mays to mitigate these issues I want to hear them.

^^^^^ He pretty much nailed it. For example, the extremely beefy Currie tie-rod will not fit with a 15" rim.

I have no idea why 15" are so much less than larger sizes. Many people run the 15"s so, it can be done. You just have to be aware it may affect other mods.

I have pro comp 1069 with 3.75" BS and I have the Rock krawler tire rod. No problems. no grinding. All is good.

But you all have me worried that my steelies in storage won't clear my new tire rod! I better check that before my next run! They have 4" BS.

Oh, and either way make sure you are careful with wheel weight placement if you use stick ons. Again, I did this with good results.
