205/40/17 or 205/45/17? (Also, Powdercoating)

[thenamessean04]

Hey everyone,

Does it matter which of the above sizes I buy and why? I'm pretty broke, and 205/40/17's are way cheaper. how much would my speedo be off? What does everyone think? Also, does anyone know a good place, or any place at all, to get stuff powdercoated? I want to get the billit mustang door and have it powdercoated black (or Anthracite to match the wheels if possible).
I could really use some input! Thanks!

I am running a 215/40/ZR17 and they work out great. There is no difference in my stock size and odometer reading. When I was setting up my wheel and tire combo I too was thinking of a 205/45, but it wasn't that much different of a price. I'm sure you'll be fine with either choice. See ya.

I was running a 215/45-17, and did'nt notice much of a difference on the speedometer.

I too, was wondering about a powdercoating place to powdercoat my fuel door black.

with 205/40/17s you will have a slight machnical advantage over 215/45/17, but you will most likely damage rims more often
