I've had enough of this wheel/tire nonsense!

I've been trying for a while to make a final decision on the wheel/tire combination for my son's '74 Dart Sport. Thought we might go with American Racing Torq Thrust II 15x8 rear and 15x6 front (large bolt pattern). Their website application guide only recommends 15x7 as widest wheel for his car. Then I run across a local dealer with some decent pricing and I can get Cragars cheaper (actually, my first choice). OK, so let's look at Cragar. Now, I'm told Cragar doesn't make 15x6, so 15x7 sounds a little wide for the front.

While the guy is confirming this size issue, I start looking at tire options. Want something to have the ol' muscle car appearance (no roller skates, thank you very much). How about Goodrich T/A Radials... 245-60-15 in rear and maybe 205-70-15 in front to be close to the same tire height. Nope, tallest would be 205--60-15 (1.88" shorter). Well, how about a shorter one in rear, like 245-50-15? Nope, don't make it.

I'm about to pull my hair out. Why does this have to be so complicated? Someone have a solution for us? We don't have to stick with Goodrich, maybe another brand, I just liked the white letters. We could go black walls out.

Help,
Jerry
