Just bought a 07 AWD Edge SEL. Ive done my research and by the looks of it nobody really goes for the off road look on the edge which is why Im making this post. I drive on dirt trails and in deep snow during the winter and was wondering what would be the biggest tire size I can put on a 17 inch rim without having rubbing issues on stock height suspension? I know the stock tire size for the 17s is 235/65 but was wondering if I can run a 245/70? Thanks!
