Need Advise ASAP Gonna order Hoosier Quick Time Pro's Tommorow

[Mustang_GT_90]

Hi guys I need help with this pretty quick, I'm gonna order a set of Hoosier Quick Time Pro's tommorow and I need to check and make sure they'll fit my 90 Mustang. The wheels are 8 inch welds and I'm wanting to run 26x 9.50-15LT Q 8.0" 26.1" 82.0" 6-8" 8" 9.5" Quick Time Pro's. My friends tell me this is the size to go with, I want something that will hold me down into the mid 12s in a 5 speed spraying 150 shot.
Will they fit, anybody using these are there any problems with rubbing, duty will be mainly at the track but ocassionally cruising on the street with them and I want to make sure they aren't gonna rub. The car has 265/55R15 Cooper Cobras on it now and they don't rub so I think they'll fit.
Any advice from guys running these tires or a similar type would be greatly appreciated.
Thanx
