If you look in the Wheel Encyclopedia thread the OEM 18" wheel is:
18 x 7.5 with a 44.45 offset. I have a set in a shed and that's what's stamped on them. They are or an 07 Wrangler. You can use this info on the calculator on RimsNTires or similar site for figment info.
Thanks - after much searching I did finally find the offset. I still had a concern about fitting the HD brakes without touching and it appears it should fit.
I went ahead and bought the five I found on CL - it was a great deal IMHO at $265 for all 5. They are brand new, owner took tires off at 140 miles to put on other rims.
Ok - so I fit them on the WK2 and they fit with barely enough space for the brakes (see pics). Any concerns? Seems really tight but there is no contact.
Next decision is which tire and size. I will probably go with the 265/65/18 because I'm concerned about rubbing on the nut above the wheel and possibly the inside of the wheel wells at full turn with anything bigger. However, these wheels, having a 44.45 offset vs 56.4 should stick out further and not be so close to the suspension components (there is less backspace on the 18s (6") than on the 20s (6.7) - both with 265s). Am I understanding this correctly?
If I went with a 275/65 I'd have more selection in tire but the overall width would go from 10.4" (for 265 tire) to 10.8" (for 275 tire). I'm concerned about rubbing. I read through the tire threads and it looks like some people are fine and others have rubbing.
Anyone with 18x7.5" Wrangler wheels able to comment? I have a '12 Overland V8 with QL so would like to know if there is any rubbing in aero and park mods.
Also looking for recommendations on tires. Leaning towards Goodyear SilentArmors if I go with 265. If I go up to 275 it opens up the field by quite a bit. Any recommendations on tire (mild offroad like fire roads, beach and snow in the winter)?
