If you have the wheels, bolt them on and take a few measurements to see what kind of space you have for tires. The clearance varys from side to side and from car to car. What will fit someone elses car may not work on yours. The only real way to know is by installing them and checking. Will the dealer mount them up so you can check fitment? One of the Discount tire shops here has some gearheads employed that are very helpful in getting tires that fit.
This is about the equivalent size of a 26 x 10 slick, so they should fit. I run a taller 275/60/15 M/T ET Street radial and have plenty of room, but I did roll the fender lips for clearance.
I also run a 28 x 10.5 M/T ET Drag slick at the track and they fit (although close) as well.
You'll like these tires, I just had a 1.514 60 foot in my small block car with them last weekend at 17 psi. Aired em up to 22 and drove it home!
Rolling the fender lip makes sense to me even if not needed for tire clearance, why leave a sharp edge in the tire area? The wheel well must be plenty full now, I am assuming the film is still at the FotoMat
