So I go to Discount Tire Co. Although I like their prices, I really dislike how they always have to "go take a look" at the car/tires! WTH? I know what size I need/want, just get the danged tire!

I always have the feeling that they (tire sales weenies) are trying to pull a fast one... Anyway, I was going to get a cheapie $86 tire (which then turns into $122 what with the envirocrap fees, taxes etc

) and the weenie says that since I have a 4WD vehicle that I should get the same make/model tire thats on the car now.

Why? Because even though they may be the same size, tires from different manufacturers might be of differing heights and would thus damage the drive mechanism
I though what a bunch of hooey but then he pitched the offer: hell also sell me
3 additional certificates to cover the original tires that came with the car so that if any of them get damaged, they will fix or replace them! SWEET!
