Ya I work at discount tire, that's how I got them. I asked my boss if I could have them, they were just sitting in the dead bin... Ya know something tho, they don't hook up for **** compared to my 275/40/17 Goodyear Eagle F1 A/S!!! I don't know why? they are the Goodyear Eagle F1's just not the all seasons... Btw I took them off today after roasting them in the parking lot at work a few times. My boss is pretty cool. They bulged out probably an inch on each side lol. took me a few minutes to dismount them, the bead kept seating on me lol...looked bad*** from the rear tho but real goofy from the side. all cobras came with 9" wheels right? if there are true cobra wheels that are 10" or 10.5" i want em bad!

Actually the Recommended is 10.5-12.50 as seen here, but your right for max contact patch a 9'' in wheel shouldnt be used.

O, sorry, I forgot, they were goodyears. BFG's are the ones that are cut extremely wide, my bad.

as you can see, the BFG 315's there aren't recommended for anything less than a 11" wide wheel. The rule of thumb is usually .5" below the minimum or .5" above the maximum

true, but when you put a 315 on a 9" wheel, the contact patch will suffer, and ultimately the center most likely won't be fully in contact with the road, so you'd end up with something like this. It's a bit emphasized, so it's not AS bad, but it does reduce the surface area that is in contact with the road.
