thanks Colin for your help, my mheels are 17 and 235/65-17 this are the best choice in the comfort way , but I think this car brig from factory shocks heavier than the standar ,I would like put some 18" or 20" wheels but here where I live the roads are very bad and the feeling will be worse. I think is possible get a differnent shokcs type to improve the quality ride.
