TIRE help!

Ok so there is this Porsche, we need to find tires. Some of this is a bit odd to me, and the closest thing I can find are Mickey Thompson tires that are DOT approved. Or goodyear's 387-236-097. There is not much space to spare, the car is packed tight!


Here is what is on the car:
bluestreak speedway specials by goodyear
10.50-16
24" tire height
rim lip 17.25"
tread width 9.5"
