I am in the same situation right now trying to find a wheel combo that I like and that fits. I really like the Tenzo concept 9's but aren't offered in a 10" width or in a 20" height.

I am now onto the TSW Max's and the manufacturer is saying that the rear 20"X10" with 40mm offset will rub on the outer fender.

I used the wheel/tire fitment tool in the sticky and I am showing different than what TSW is saying. I am showing that with the 20"X10" with 40 mm offset i would also need a 5mm spacer since ideally the offset should be 35mm.

I posted the links below with what I have found for stock vs. the TSW wheels that I would like to use. I would appreciate someone pointing where I am not adding this up correctly. I am taking the stock wheel width (9") and subtracting the backspace to get what could be called frontspace of 79mm. I am trying to keep the same outside diameter and add the extra width of rim (compared to factory) in towards the shock and spring. I don't know if this is the right way or not, just seemd like common sense to me. What I don't know is what clearance I have from the inside of the stock wheel to the closest part of the shock or spring of the xfire suspension..... The more the + offset the more tucked in uder the fenders the wheel will be right?

Will this wheel/tire combo work?

TSW Max 19"X8.5" 43mm offset front and 20"X10" 40 mm offset rear
