As my car (now named lucky) is going away soon, (very soon) I am preparing it for departure. It will get it's engine problem (whatever it is) resolved next week hopefully, MOT'd, no doubt back in for something else, then into a local body shop to get dings and scrapes fixed. It also required two new rear tyres. Loving this car as I do, when I passed a sign that said part worn tyres £18 each - I could not resist. There I found to my amazement two identical Pirelli's for £25 each fitted. I have since however found that these are winter tyres - 225/50R17 94H WINTER 210 SOTTOZERO SERIE II. Other than they need balanced I haven't had any issue however can I run these on the rear with normal tyres on the front ok?
