How much can I expect to pay for a set of used all weather tires for a 1996 Suburban, to include mounting and everything?

I am pretty leary about used tires, but if you must then call for an accurate price (local Schwab store). Don't know if they sell used tires. They will buy your old tires that were purchased from them but not warn out yet.

For mount and balance more around 225 to 300$ and tires

Probably around $200
