hey,
les schwab has a machine that alows you to see your car, your color, and with many rim options. the best way to find out what size is to ask someone at the store you are going to buy from. they usualy have access to the most recent info. they will also give you options on tires. choose wisly, it is a big up grade and spendy as well. another place is at
www.tirerack.com
they might not have your car but it is worth a try.
like to see what you buy , good luck.
