The stock 20's are 235 X 55. Personally I wouldn't exceed that size at the risk of handling geometry changes. inside fender well rub, etc, etc. The problem is you wouldn't know if there are any problems until you had purchased, mounted and driven the oversize tires. It could be an expensive experiment.

The Michelin 235's are plenty beefy and give a great ride.

Way up there! N of Barrie. I'm across the ditch in WNY.........just a tad too far and a border to deal with. Too bad, I could be very interested in the rims. GL to you!

Rosco, I recall a guy on ebay selling the 20" OEM wheels and rims when he went to a 21" custom wheel. He had them mounted and all wiht 255/50/20 tires and they worked great. I did a quick check on Tirerack.com's size chart at the time, (great tool for comparing tire fit/sizes) and they were within very close specs and obviously seemed able to fit. So go with it!
