Hi all,

I am in dire need of new tires, and can't find the tires I want (Pilot sport 4AS or Pirelli P7) in the OEM size at Costco/Sams. However the 255/45/17R size is available and ready to install. I used a few calculators and there's only a 2.5% difference between diameter, so theoretically everything is OK, just going to be going slower than my speedo says by a few MPH which is OK.

Are there any other major issues I should be aware of? Apparently the ride quality should be better too?

Thanks!
