Ideal tires for RUF Speedlines on my '88 Carrera

To Bill & other tire "gurus",

What are ideal tires to put on my narrow body '88 Carrera with 8 x 17 et 30.4 front & 9 x 17 et 17.7 rear RUF Speedlines?

I am currently using 215/45/17 front & 235/45/17 rear Michelin Pilot Super Sports.

Tried 225's fronts but they rub on the inside fender when turning. Can I clear oil lines if I go 245's for the rears?

I prefer function over form & prefer not to use spacers. Car is lowered slightly below euro. Rarely driven on track these days. 6-8k miles/year.

Thanks in advance.

Though the wheel widths are normal for an SC/Carrera the ETs are on the 'in' edge of the fitment range

normal front is 8ET25-30 w/ 225/45 x17 ET30 moves the wheel/tire assembly to the inner edge of what works, which is why the 215/45 is ok but the 225/45 hits on the inside. One option is a ~3mm spacer +225/45 tire.

same sort of thing is the back normal would be 9ET12-17 your ET 17 puts the wheel/tire assembly to the inside of what fits, 245/40 would be a better rear than 235/45, the 245/40 is ~.7" shorter the car will feel slightly livelier(+~3lb-ft) you could also use a 2-3mm spacer here too.

here's my choice in a MSS 215/45 & 245/40 or if you added the thin spacers 225/45 & 245/40

or since ss doesn't seem to offer a 255/40 maybe PS2 225/45 & 255/40 this will impose a few lb-ft of energy cost but not too bad, The extra grip may or may not be worth it too you, you'll have to decide that.

Lots of other sticky 225/45 & 255/40 choices too, I use Direzza * spec and RE71 on mine

The Michelin PilotSport 4S is the replacement for the MPSS, and came out in 17" sizes literally yesterday. Supposed to be an amazing tire. They've made some technological leaps with tires in the last 2-3 years.

Thank you Bill. I will consider the options that you have outlined.

Driven- thanks for the news re availability of the 4S in 17's. Spoke to my supplier two weeks ago & he told me they only could get 4S's for 18" & above.

It's not often you get to provide 24 hour old information on a web forum about 30+ year old cars.
