i recently ordered 33x10.50 km2's along with the 15inx8 rock crawler series street lock wheel.it did not dawn on me until shortly after i ordered them that my callipers might be an issue.my first question is what is that smallest size you are able to go without having an issue with the callipers.also with the 33x10.50 tire size i could not find many wheels that would mount on them.if you could suggest some wheels for me to check out that would be friendly to this set up i would be grateful.if it helps this tire selection is more important being i am running stock suspension for a while. i searched for other rim and tire threads but they could not directly answer my question. also forgive me for my iggnorance im new to the jeep world but proud to be a part of it. thanks.

 

what i meant to say was there is not many tire brands that hold these dimensions on a wheel bigger than 15 inches. please steer me in a direction for a nice mud terrain tire that will get decent life expectancy.i believe the km2 in 33x10.50 can only go on a 15 in wheel

 

There are people who run 15's on here, some are fine, some arent. I have 16s, and some people have problems with them also and some dont, mine are fine. You may be able to grind the caliper for clearence if its close.

BFGs are an all around good long lasting tire, but there are many opinions on this.

 

depends on the offset of the wheels. If the offset is wrong they won't work, but some here have reported 1.5 inch wheel spacers take care of offset issues.

Do a search, and get your backspacing to compare. 33 inch KMIIs is small for that tire. Why not go bigger on 16 inch rims? Stock, your JK came with nothing smaller than 16 inch, so you should have done some research before making such a major purchase.
