Off roading isn't really the issue, unless they are poorly made with loose tolerances or with low quality (weak) materials. Otherwise, off-roading tend to be done at much lower speed (lower impact forces) than normal driving, really doesn't add more stress or wear on other components like wheel bearings. Over time extreme spacers will accelerate wheel bearing wear.what spacers did you get? Ive heard some horror stories about them, especially if you go off road
Good information, thanks.
Will the offset created by the 1" spacers damage the axels, bearings, tranamission, etc.?
"When properly installed, high quality wheel spacers that bolt on to your axle and then your wheel bolts on to it will behave no differently than would a wheel with less back spacing. I have used wheel spacers on ALL my Jeeps at one point and time over the last 20 years and have NEVER had a problem with any of them. The key is "proper" installation and a routine check of them just like anything." (http://toasterjeep.com/index.php?threads/renegade-budget-boost.318/)most probably it will.... :-ç
I'm looking at doing a 2 inch thick 5x110 to 5x110 spacer for the stock tires (Source: http://www.performancewheeladapters.com/lugmanusa-life-time-adapter-build-your-own-5x110mm/).
Other than installing them correctly, should I be worried about anything else?
2" is a lot. A thing to note when spacing the wheels further out, it changes the clearance you have when turning the wheel to full lock. The contact points change on the front and back of the tire.
I used BFG 215/75/R15 Mud tires which come out to the same size as the Trailhawk's wheel/tire combo. When I spaced these out by 1", I'm getting slight contact at the back of the wheel against the plastic fender well trim when I'm at fully turning the steering wheel. The front of the tire still have plenty of room.
When I used a wider and larger diameter tire, Kenda 235/75/R15, I get a lot of contact in the rear. Not only the plastic fender well trim, but also the end of the side skirt. I also have contact in the front of the tire against the plastic fender well trim.
So stock tires with a 1" spacer gave me slight contact already. 2" will give you similar if not more contact than my setup with the Kenda 235 with a 1" spacer. You might actually be hitting the outside edge of the fender on the back side of the tire at full wheel turning lock.
With the BFG 215 I was test fitting. Once I saw I could get more room under there, I skipped the 225 because it was already proven to fit and tried a size larger with the Kenda 235. A thing I notice with the 215 (or stock Trailhawk) tires is that they are very thin. In stock form they suit the Renegade well. Spaced out 1" the Renegade's stance looks like it's standing on toothpicks. The size of the car and the gap between the tire or the gap between the inside of the tire to the inside of the fender doesn't look right to me. So I filled in with a thicker tire. A skinny 215 tire at 2" out wouldn't look right to me. Use the outside edge of the fender as a reference point and figure the ratio of tire you want on both sides of that reference point. About 25% of the tire past the fender and 75% of the tire tucked inside of the fender is what does it for me.
Only time will tell. The 9 speed is still too new to find its limitations. Check the cheerokee forums since they have been using this transmission longer.Great answers on the bearings but what about the 9 speed transmissions.
With all the problems people are having they seem really sensitive and I wonder if they will turn to mush under the stress of larger or offset tires and void your warranty?
