Default Larger sidewalls

The first pothole I hit in '99 with my 2000 Jaguar S-Type dented two rims and blew one tire. I had slightly taller tires installed which made the ride a litle smoother and no more dented rims. My 2013 A7 Prestige with 20" Sports Package comes with summer tires. What is the tallest tire (largest size tire) that I can have installed on these same rims? Thanks

You can't change the profile without changing the rims

To do so would affect the overall diamater of the wheel/tire and affect your speedometer. Not to mention what it might do to your safety/traction systems if the overall diamater gets too far off the original

If you want larger sidewall, you will need smaller rims

Also, a taller sidewall may not fit under the wheel wells without rubbing, especially with the lower sport package suspension.

I love the look of the 20 wheels that came on my A7, but the ride is a little harsh and I've curbed/repaired those suckers more than once. My winter wheels are 19 x 8.5 and the tires on those are 255/40R 19. The ride is more comfortable and the taller sidewall means fewer curb encounters. When I order custom summer wheels, they'll probably be 19s not 20s for those reasons.

Agreed. Love the look of the 20's, however I chose the 19" for comfort and all-season tires.
