Question for the experienced Jeep people; I’m eyeballing these wheels as a possible replacement for my OEM 18” wheels. The -12 offset concerns me though. Will these wheels have huge poke, even with 255/70/18 tires?

Thanks in advance!

Is you Jeep lifted now? Is a lift in its future? Certain lifts require certain amounts of backspace, which becomes more important with the narrower axles of non Rubicons.

Also, it's worth mentioning that a 17" wheel will open up more tire choices that are also generally at a lower cost for a given diameter and width.

Tiresize.com has a great calculator that allows you to enter what you have and what you're interested in, than provides an overlaid image and clearance numbers that directly compare the changes.

Go into Wheel Offset Calculator from the homepage. The factory offset is 44.45mm.

Thanks for the responses! I did some digging and checked out the thread you shared. Probably too aggressive for my taste.

Take a look at 17 X 8.5 wheels with 0 offset. Those sit within the fender. They have a 4.75 backspacing.

These might be closer to your taste.


As @Headbarcode has said. If you are going to use a lift, check with the manufacturer to see what wheel offset they recommend with their product.
