Track wheels finally here!
E30Dom:
I was thinking of getting the 225/40 R18 R888's but worried about rubbing, is the profile anymore more bolbous than normal 225/45 R17 tyres?

I don't know about the 18" R888's, but the 17" ones still rub very slightly under maximum compression. I'm now having some custom adjustable top mounts made to dial in a few degrees of negative camber and have the arches rolled for good measure :happy2:
The static radius of the 18" R888's is slightly higher than the 17's (about 4mm). More importantly...like you asked...the wheels are slightly more bulbous than normal tyres, so you'd certainly be risking rubbing with the lowerage you currently have :happy2:

Cheers, That was what I was afraid of...

were did 24.1kg come from?
i just weighed my pascara wheel and brand new michelin ps2 tyre together they were 20kg bang on. thats only 70g heavier than those 17s
so using that calculation 2.8kg, which is the equivalent of taking around 14kg out of the sprung weight of the car.

The 24.1 kg came from my Pescara's with Conti's on.
Can I borrow your scales for my tdpr's please :laugh:
On your calculations and based on someone on here who weighed the Pescara's without tyres your 18" tyres only weigh 8kg, which is pretty damn light if it is spot on.
The R888's may weigh a little more than stock tyres, but certainly not 3kg more!
