i bought these tires in 2010. i put them on my vehicle on the monday following thanksgiving day and remove them between march 15th & april 1st. i had them studded and recommend anyone buying them to do the same. i have probably 3-4 years life left in them. they far exceeded any expectations i had for them. i drive on dry roads, rainy roads, snow and ice with full confidence i am going to arrive safely. i know i can travel at the posted speed limits even in icy conditions. i will be buying them again when i or if i need another set. buy these and drive with confidence.
