You could also check out discounttiredirect.com. They have free shipping and everything so it wouldn't cost a fortune, plus thier prices are cheaper. My Nitto 555 Radials are only 169 each out there with free shipping where Steeda has them at 209 each plus shipping...
BUt I agree with Brent, if you are going to go 17s, wait on good tires till then.
