I'm not sure of the question? Are you wanting that combo as an orderable option? Or are you going to upgrade to 20" wheels from 18" or 17"?

To the first question - you can't order 20" wheels with 3.31 gears - tried. 3.55's are as tall as you can go with 20" wheels.

The second question - you can put any size wheel on there you want. What matters is the tire diameter. If you have anything other than the stock tire diameter the speedometer and odometer have to be calibrated to the new size - different diameter tires turn different revolutions/mile (change in circumfrence) = slop in the speed and mileage readings, the bigger the tire change the bigger the difference.

I know about the order thing, I tried also. I'm looking to replace my 18's with new 20's.

Thanks,

Shane

Sure, you can do it. Steve outlined the only real concerns.

Tire size can be reset by IDS to provide accurate speed readings. When AutoEnginuity releases the 2011 update next summer, their software will allow owners to do this themselves.
