I measured the tyres at work today (I am the Parts & Service Manager for a Franscised Garage) & they have 5mm tread left. New tyres normally have around 8mm tread. They are Michelin Pilot Preceda & would retail around $210.00 - $230.00 new if you could buy them but I believe they are no longer available.Keep in touch I am sure we can come up with a good price that will keep us both happy.
