Nice wheels. Ive ran a 10.5 on a 8 inch wheel and does have buldge.
the 275 40 17 drag rads I bought have got a trailblazer ss 1.501 60 foot time and hook hard even at the street races with a 150 shot off the line.
i got these 17x8.5s from discounttiredirect.com for 206 shipped to my door.
i wanted a small height tire. with a 275 40 17 you are in the sweet spot going threw the lights and 3rd tops out at 122 mph which was good for a 11.4 on the trailblazer ss. also a stock 2wd ss borrowed the wheel and tire combo and just hp tuner was used for the difference in tire height ran a 14.1 stock and a 13.6 with teh drag radials. the 275 40 17 make the thing just go threw the gears fast.
i run at the street races and also on the street a lot and ive used et streets and ride just sucked. They hooked great though but didnt like the bounce at all. If you end up getting a 255 50 16 im sure you would be happy with that in a drag radial tire
ps-remember to tune for the difference in tire height or the truck will shift to early and truck will act funny driving around
