18" BBS LM advice fitment

[Rajvosa]

Hi guys bought some 18" BBS LM's off a friend who had it on his E36 M3. As im going through an engine swap im unable to take the car for a drive to see if its rubbing anywhere etc...

wheel specs are:
18 x 8.5 ET30 (all 4)

tyre specs are:
215-40-18 fronts
225-40-18 rear

tyres will need changing anyways so my questions are:

1) can i widen the front to a 225-35 or keep at 215-40. i dont want any rubbing especially on inner guard plastics when turning

2) whats the best tyre set up for this wheel spec ?

ive mounted the fronts without any spacers and rears have a 15mm spacer (225 tyre is sitting close to the guard, hasnt been rolled)

thanks for any advice

current 225-40 rear tyre


old 235-45 tyre

well from looking at online tyre size calculators seems that putting a 225-35-18 ends with a smaller diameter than a 215-40-18... so im guessing i should change front to that..
am i correct?

I that a mk4 r32 in the background? I had one, what a great car!

Sorry. Can't help on tire sizes, but I hope you can go with AT LEAST 225s.
