I am lookin at gettin some new tires and i was wondering if i got 205 50 15 instead of 205 55 15's on my stock gt rims would it hurt anything but my spedo beign off 3%? Im gettin some Falken Ziex 512 and there like 15$ cheapers a tire for 50's. Also are those tires very good tires? I can get Kuhmo asx are they better?
Thanks for any help.

i wouldnt worry about a 5mm difference.

i had those Falkens on my stockers and loved them, they were awesome for $60 a tire. however, they wear really quickly and the wet traction substantially decreases with wear.

205/50 is a great tire size.. thats what I use but with 15x6 steelies..
