Hi all, i was hoping some one might be able to help, i recently changed my front tyers on an Astra 1.9 diesel sri 2007 as they were pretty slow on tred, the backs were ok and because of money being tight at the time, i thought i would do the front to now, then in a couple of months do the back with the same make.
A couple of months have gone and ready to do the backs, the issue i'm having at the moment, is when i go over 70 the steering wheel vibrates like crazy. I checked the old tired front and back and i used to have 225/45R17 94W
The backs are still this but the fronts they put on a couple of months ago are 225/45R17 91Y
I just wanted to check before i go in and get the backs change from 94W to 91Y to match the fronts (and balanced in hope the vibration goes) does the 91Y matter, i was worreid that because its a different number they fitted the wrong size on the front. Thank you for any help and hope i explained it ok.
