Larry D Posted April 11, 2016 Report Share Posted April 11, 2016 Im looking at some wheels, 8j with 8.5j at the rear 18s. ET is 40 front and rear, what width can i go upto on the rear without ruining a standard arch? Thanks for your time. Quote Link to comment Share on other sites More sharing options...
Daz 330 Cs Posted April 11, 2016 Report Share Posted April 11, 2016 You can use the stock set up as these sizes are the same as OEM MV1 or 2. MV rears are ET50 ish iirc. So 225/40/18 fronts and 255/35/18 on the rears. Quote Link to comment Share on other sites More sharing options...
Larry D Posted April 12, 2016 Author Report Share Posted April 12, 2016 Thanks for the reply daz. I phoned the seller, he seems to think 235, is max, wonder why that is? I checked, MVs are indeed ET50, which means you could comfortably run 10mm spacers on your rears? Quote Link to comment Share on other sites More sharing options...
SamW Posted April 12, 2016 Report Share Posted April 12, 2016 If you added 10mm spacers to your new setup it would make the wheels et30 Daz 330 Cs 1 Quote Link to comment Share on other sites More sharing options...
Daz 330 Cs Posted April 12, 2016 Report Share Posted April 12, 2016 Yes as above, the lower the ET, the further they sit out. You can definitely go wider than 235 on an ET40 8.5J. Quote Link to comment Share on other sites More sharing options...
R11CH Posted April 13, 2016 Report Share Posted April 13, 2016 I have 255/35 on my 8.5j et40 wheels. I have even put 12mm spacers but since the suspension has settled its catching the arch so il be going down a tyre size. Quote Link to comment Share on other sites More sharing options...
