Caymen,
don't tell them, let them pay more for the better gas:rolleyes:
it all comes from the same place in your area......... less than 2 gals of additive per 9000 gals of gas tham makes it shell vs el cheapo ect..............
the cobra is a soft rubber tire. don't get me wrong they are good tires, but as heavy as the trac is.............. you may grind them down pretty fast.
