On the driver door pillar, the mfg tire sizez are P205/55R16 for summer and P225/55R16 for winter. What's the widest size tire I can fit on these wheels? Does anyone know the width of the stock wheels? Also, I'm considering aftermarket wheels, but I'd like to move up to 17"maybe 18". What's the offset and bolt pattern I should look for? Thanks for your help!![/align]
