Just bought a used 2005 black v, great car and the dealer put four new tires on, two at a time. Just picked up the car tonight with the second new set (he had planned to put on two new ones, but I pointed out that the other two were down to 3/32nds so he decided to replace them, which was nice). Well he put Goodyear EMT F1's on the front the first time, and now he put Goodyear EMT RSA's on the back. I dont know if he realized it, I didnt look that close until I got them home. I cant imagine he did it on purpose, and I dont imagine it is right to have two sets of different tires on the car. Given my druthers, I'd prefer the RSA's. any thoughts on this??

Pick one set or the other, but they should definitely match.

F1's are sticky , Rsa are not but will last.
It depends what you are looking for but don't stick with one kind in the front and the other in the back.
good luck
