2000 XK8 with 18x9 double five wheels on all four paws(sorry, feline humor).
 

I like the look of factory rims with a more aggressive tire. I put the 18x9 wheels with the 255/45s on the front fully expecting them to rub. they fit well and looked good with no rubbing. I then purchased two more 18x9 rims and fitted them with 285/40s(same revs per mile as the 255s) and then added 20mm spacers to help fill out the rear wheel wells better. I do not use spacers on the front because it changes the factory wheel pivot point when you turn the steering wheel. With the extra girth I thought the car started to mark its territory but alas it was the convertible top hydraulic fluid leaking on the driveway.

Hows the comfort with those nt555?

It had three different brands before I replaced them all so hard to compare but they handle great and are grippy in the corners.
