Jim27 Posted August 23, 2016 Report Share Posted August 23, 2016 (edited) Can I pick the zone's collective grey matter, please? I've got 19s on my 330ci. Rears are 19x8.5 ET43 and the car is on standard sport shocks with Eibach lowering springs. I want as much sidewall on the tyre as possible to give it some squish to absorb road impacts (and hopefully avoid ANOTHER cracked rear wheel). 235/35r19s were too shallow and ended up with the wheels cracking. 255/40r19 give a tonne of sidewall but unfortunately scrape like a b*****d on the wheelarch/liner. I know this because having just spent nigh-on £200 on these tyres and fitting I almost started sobbing when I heard them scrape from the moment I pulled off the drive. So what tyre size would you recommend? Edited August 23, 2016 by Jim27 Quote Link to comment Share on other sites More sharing options...
momo Posted August 23, 2016 Report Share Posted August 23, 2016 Go in between? 245/40/19.. Although if you want sidewall - it'd be better to switch to 17's.. 18's at the very least! Quote Link to comment Share on other sites More sharing options...
Daz 330 Cs Posted August 24, 2016 Report Share Posted August 24, 2016 You'll need to switch to 18s if you want huge sidewalls. I ran 9.5J 245/35/19 for years with zero issues. Yours are only 8.5J though so you can't go wider. You may get away with 255/35. Need to get the calculator out to work out the percentages but it's coffee time Quote Link to comment Share on other sites More sharing options...
