Saving on work truck tires

I couldn't believe it the other day when  my husband said we were going to need tires on his work truck before winter. Being there's six tires on the truck at a hundred and thirty dollars a tire with installation it's really going to take a dent in our savings. But what are you going to do when it comes to safety on the sleek roads of New York. I shopped around online and came up with another tire company tirerack.com that will at least save us an additional seventy five dollars on a cost.
