If you use a Goodyear card you double the rebate . The rebates change , it will be whatever it is at the time of your purchase. I just got $160 back on 4 GY Endurance at $111 each . Mounting, balance plus new metal valve stems plus a road hazard warranty will be negotiated by you and the dealer.
I just bought 4 new Endurance tires , the warranty was explained to me stating , "The GY / RH warranty is not prorated and replaces a damaged tire at no cost to you". The manager waived the mounting, bal and valve fee. The RH warranty was $20 per tire for 3 yrs.
Each tire = $111 + $20 . price for 4 was $131 x 4 - $160 was good enough for me. I might have done better elsewhere but I don't have the time or care to shop around .
