Help with Tire Selection
I have a 2005 XKR that appears to have come with 18" wheels if the sticker on the door is correct. Someone changed them for 20" and installed 285/30 on the rears and 255/30 or 35 (I think) on the front.
I took a long trip last weekend and don't like the ride (too rough) so I'm thinking about getting tires with larger sidewalls but I don't know what would fit.
I know it can/will change the speedometer too but that's less of a concern than the ride.
I could always go back to 18" wheels but would prefer to not have that added expense if a 20" higher profile tire would fit on it.
Any thoughts/ideas would be welcome.

The stock tire/wheel sizes are listed under the armrest for reference. Going out of what is specified will likely not get you where you want to be. You will likely want to change your wheels to something smaller (and fitting your brakes!), and get the corresponding new tires. Assuming the wheels/tires you have are stock and in decent shape, you should be able to sell them for the cost of these smaller wheels. Then the net expense is just your new tires for the smaller wheels.
Have you checked and adjusted your tire pressure? Unlikely to be a huge change, but every bit helps...

I would replace those wheels just on principle. Those are just not right for that car.
Here is a good deal ($650) on a set of 18" Double Fives from an 02 XKR with new-ish Conti Extreme Contact tires.

Would look a lot like this

Exactly, these are wheels that came out for the earlier XKR without the Brembo brakes.
There is a TSB, but it is not definitive:03 XK specs.pdf

Yes your wheels are f-ing great, brakes are normal, nothing to justify.
The 305 mm discs at my 97er are humble, and then the 17" Revolvers........
I love it!

I was wondering about that. When you look at the photo it kind of looks like there might be ones at least on the front. There is a different colored area where the wheel meets the rotor. The rotor is obviously rust colored.
