Tire size question

I have a 09 Unlimited X 4x4. I have been told that the 285/75/16 will fit with proper backspacing under 4.5. I just had the idea to go to a 15" wheel with 33/12.5/15 Duratracs. The only thing that changed was the width of the tire + 1.3 inches. I think this will work and it will save money.

My question to everyone on this forum (which all have more experience and knowledge than I do about this) is--- Will this setup work with no problems?

Thanks, Mike

Is there any kind of lift on your Jeep? I ask because both tires are 33's...with the potential for rubbing if you go offroad and stuff your tires into the wheel wells.

As far as the pudge factor, you can adjust your backspace accordingly to make sure the 33/15's don't rub your swaybar links. Instead of 4.5" bs, look for something around 4" or less (not MUCH less, though, or your wheels will stick out too far and put extra stress on your bearings.)

If you decide to go with the 15" rims, make sure they'll fit over your brake calipers. Most alloy 15's will; many steel 15's won't. Contact DTD (forum vendor) via PM or phone...they can tell you what'll work and what won't.

Also, with the new backspacing (whatever it is) your spare will stick out from your tire carrier more than the stocker. You'll need to buy a set of Daystar Bump Stops ($10, I think), to replace the factory bump stops. Make sure you measure em a little bit long before you cut em, so the tire will snug up against em real tight. But don't go too tight, or they might dimple your tailgate.

I really do not plan on doing any offroading other than going through an occassional pasture or two. I figured the 285 and the 33's are the same. The only reason I am thinking about going to a 15" is the cost of the tires.
