upgrading tires and Wheels

im upgrading my tires to either 33 or 35 X12.5 on 15 R , but my issue is that the 15'' rims wont fit on there due to the obvious , i currently have 16'' wheels what is the process to go to 15'' wheels or whats the best way to go about it?

with proper backspacing 15" alloy (and some steel) wheels will fit fine. if the wheels don't have adequate backspacing, just get some spacers.

as far as a process, just go out and by them. if you're not sure. talk to a rep at discount tire and ask them if the setup you're thinking about running would have any issues on a JK.

good luck.

I have 15" wheels--Black Rock 909 alloys. Nothing was required other than buying the wheels and putting them on. Most 15" alloys fit. Most 15" steels fit so long as they're (I believe) 3.75" of backspacing or less.

Not sure what you mean by "weak points" . . . .

For an 8" wide wheel, anything from 4.5" down to about 3" is considered "normal" for aftermarket wheels. If 15" wheels are what you want, then most alloys anywhere in that range should work, steels will have to be down in the 3.75" range and down.

That's just a fancy way of saying leverage increases the wider out you go. It's technically true, but I wouldn't spend much time worrying about it.

Send a PM to Discount Tire, a forum vendor who you see all over this thread. They offer a number of 15" wheels that are guaranteed to fit.
