I recently purchased a 2012 Veloster NAV. It has the 18" wheels. I was going to change from the stock 215/40R18 to 225/40R18 to improve the ride and need some advice on tire selection. Does anyone have either the Continental Purecontact LS or the Yokohama Avid Ascend GT on the Veloster? What do you like and dislike about them. I live in Colorado and would like an all season tire.
