30x9x15 on a 68 dart

I'm running 15X8 w/245-60-15 on my '68 GTS. SS springs, but stock locations. It's VERY tight in there. Rubs on corners....

I'll bet, as Jeff pointed out, that there's been spring relocation, wheel wells ground down (prolly both if it looks "stock" to the eye).....something to accomodate 10".

Just my $.02
