Worried about lowering

747 Views 2 Replies 2 Participants Last post by  Polar Bear
I'm looking at Sumitomo tires 255/40R17. Currently I have stock size 245/45R17. Can I expect lowering if I use these tires? AM website shows recommended rim size for these tires as 17x9 which is the stock size. I have to drive daily over military gate anti terrorism devices so my car can't go any lower. It already rubs if I go to fast.

They are a tiny bit smaller I believe. I went from 245/45R17 all seasons to my 255/40R17 summer tires and they looked to be 1-2mm shorter overall. I don't really have good pictures to show the difference though.

Ok. Thanks. Car is already lowered on Eibach springs which is what is causing the the rubbing. Just not wanting to make it worse.
