I have an low milage 02 XK8 convertible, just as a summer toy. Two tyres are due for replacement, two wheels are slightly deformed (passed MOT OK) All the wheels would benefit from a cosmetic refurb, the rest of the car is very tidy Due to the poor ride on 20" wheels, rather that spend money on them, I am considering buying a replacement set of 18 or 19" wheels and tyres - selling the old wheels to help with the cost. Questions, For ride quality / comfort would you recommend the 18s or 19s ? Are there any wheels / wheel suppliers that you would recommend - or avoid? Do not need to be OE.
