26x11.5x15 Hoosier QTP ? Please help

Thanks 440. That helps me out. I would have measured but I tore the rear out and got my shackles put it and cut the perches off but that was as far as I got till I got called into work, 4 weeks later I want to get home to a set of new rims and tires for the track. So I'm kinda going blind. I just ordered a set of hoosier drag slicks. 26x10x15. I shouldn't have a problem with those and when they wear out ill fill the well, maybe even relocate and mini tub by then. Thanks a lot.
