At 336,000 miles I've decided it's time to replace my beloved 2001 Touring. Looking at 2015/6 w/Advance package. I do a lot of back road driving and a fair bit of dirt road/Forest Service road driving and am wondering how suitable the 2" lower profile 245/55 19s are for that sort of thing. The 235/65/17's on my 2001 are the same height as the 245/55/19's, would I be crazy to use the smaller rims? Would there be any fit issues? What sort of performance issues, mileage, cornering? Have any of you run the smaller rim/higher profile tire on a 3rd gen MDX?
