Anyone with any experience or knowledge about fitting 215/40/R18 tyres to R109 alloy wheels? i currently have 205/40/R18 runflats on them and fancy a change.
There doesn't seem to be a lot of these tyres but sourcing 215's seems to be a lot easier (and cheaper? ).
I'm hoping that i can and that it won't rub against anything??
found this link on another thread here. According to the calculator, switching over to 215/40/R18 is well within the operating parameters they specify. I also rang up BMW MiNI and spoke with one of their technicians.. says there shouldn't be a problem at all
We've got 225/35 R18 Toyo T1 R's fitted on 7" wide rims. Work really well, no rubbing issues at all. Loads more grip and feed back than the terrible Bridgestone 205/40 R18 runflats that the car came fitted with!!!
