wheel and tire fitment question

jkgts1 · 09-17-2010, 09:57 AM

I know there are a lot of these questions, becuase I have been searching. With all the different combos possible, I have not found a answer that I am comfortable with yet. I have a 09, CC, 2wd, Rough Country 3" level/lift kit, wheels I am going to put on are 18x10 with 0-0ffset (5" BS). I really want to run 325/60/18, but im not sure if it will contact the UCA or any frame/ suspension parts. I know I will need to massage the body a little. Anyone have a setup close to mine? Any input on what is needed to make these tires fit would be great.

Thanks

If the are 18x10's they are really 11" wide, and so with a 0mm offset, their backspacing is 5.5", so a 325 could very well rub on the RC UCA.

Wheel manufactures don't count the lips in the width, so their advertised widths are about 1" wider. A 18x9 rim with 0mm offset has 5" of backspacing, becaused measured it is 10" wide.

A 325/60R18 on 18x10 w/0mm will also rub at the pinch weld about the same as a 18x9 with -12mm offset ... 4.5" backspacing, because both will stick out the same.

You will need the pinch weld mod if leveled. See the link in my sig.

Cool thanks for the help. My mistake the wheels are 18x9, 0- offset, been a while since I looked at them.
