So, I'm still having trouble coming up with what tires to run. I need to run a 255/60/15 in back because that's the biggest I can get (whether it's a BFG T/A, Cooper Cobra, or MT Drag Radial, or a MT Sportsman S/T Radial). Those are pretty much my only options in that size.

Question 1- Which one of those will give me the grip and decent street manners?

Question 2- What's a good tire to match for the front in a 205/65/15 size??

None of those tires come in that size, so I'm going to be mixing. The guy at discount tire yesterday said it was a no-no to mix and match tires. I told him it's gonna be a hot rod and I'm not too worried about handling characteristics. I just wants something that looks decent with whatever rear tire I decide on.
