i've been buying tires from tire rack since about 1994
if you should have to return a purchase
there's never any problem
on one of my cars I have 110,000 miles and I'm on my 9th set of rear tires
so I periodically check on tire rack for specials and close outs for my sizes
usually can find a great deal eventually and stock up
e.g. stock lamborghini tires at $110 a tire
bought 4
those melted though in 8000 miles
softer rubber has better grip and handling characteristics
but they don't last long on alabama roads
