They drive nicely, seem acceptable comfortable and quiet for street use, while very grippy & predictable. With big brakes and 420HP at the rollers, I don't have traction issues at either end. Like 'em just fine and will probably buy another set when they wear out.
The rear size would be in spec (8.5-10"J), but the front would be a bit stretched (7-8.5J is the spec). But that's not extreme at all.
245/45/17 & 275/40/17 would seem to be a better match for 9s & 10s in a widebody, but for an N/A car you seem a tad over-tired and should maybe be careful with profile/section etc to reduce the torque loss and rolling resistance. Especially as Rufs aren't light wheels.
IME, most extreme hi-perf summer tires don't wear out so much as age/get hard; coming up on the end of the 3rd fall season, may still have legal tread - but will push, tramline and squirm around on wet roads round 40F where they didn't the year before... So hey-ho for the wheels shod with WinterContacts, and a new set of summer rubber in the Spring.
If you don't have seasons or only ran them in warmer temps, they would probably be just fine until they wore out.

Yep, where I live, we are warm(ish) most of the year. Car is currently only n/a but soon to be turboed... Trying to get my head around different tyres and how they sit on a rim. I've seen some 255/40 on a 10inch rim and they look ok... but then other 255/40 look way stretched on a 10inch rim (the lip of the rim sticking out!)
Trying to find pics of the actual RUF 10inch rims with a 255 section tyre.
Whilst the 245/40 and 275/35 sizes might be good for the 9in and 10in rims, I will get access to other brands if I can run the 225 and 255 sections ...
