I can assure our OP that 18" wheels with 50 profile tyres give a much better ride than the thin "rubber bands" that now seem so popular. In fact I swapped out the 20" that came with the car when I bought it as the ride was SO harsh. OK for a track day, but I don't go to them too often, if ever.

Actually, I'm familiar with the "rap" on the larger diameter wheels concerning "ride" and damage issues. However, down here in Florida the roads are all smooth and in excellent condition. (Straight, flat and boring too.

Thanks for the info JagMaster. Actually I'm running the OEM Jaguar 20 inch "Sepang" style wheels with 255/35/20 size tires. I wanted to compare the 20 inch tire I'm running to the original 18 inch on the tire size calculator to confirm that I have the correct size. It turns out that they're perfect. Well, as close to perfect as one can get.
Less than 1% (.85) which translates into 1/2 MPH speedo error at 60 MPH.

) Potholes? Never seen one down here. I'm actually very happy with the ride, handling, smoothness and quietness of the 20 inchers. At least thus far.
