Default Attempting 28x14.5 Quicktime Pros to replace 28x13.5 ET Streets on C4?

Well lots of drag guys on here put 28x13.5's on thier 15x10 wheels on C4's, same as i have on mine for drag racing.

Hoosier Quicktime Pro's measure differently than mickey thompsons. Hoosier run more tread on the ground for the same amount of sidewall width (which is the part that rubs or becomes the problem)

Heres the specs on a 28x13.5x15 ET Street
13.2 sidewall width, 11.0 tread on the ground, 28 tall

Heres the Hoosier 28x14.5x15 which is another INCH on the ground. (12 on the ground):
28x14.50-15LT , 12.0" of tread on the ground, 28.0" tall, 13.1" sidewall width which is narrower on the wall than the ET street but another inch on the ground.

Anyone have any insight into this?? The 28x13.5's MT's barely fit right now but they do fit.

WOW Jim Voles comes back with another name. How long before you rip off someone in the parts section. How many times have you been baned? 4 or 5
