Any comments for OEM wheels?

Don't see a problem with it.

use this. You should stick with 225/40 up front and go with 255/40 in the back.

225/35/19 is way to short on the front

This guy knows what he's talking about. 245/35/19 & 255/40/19 on the rear.

Discountire lists plus sizes as 245/35 and 275/35, is that not a good idea? Why do you recommend the rear be 255/40 instead of 35?

I believe those plus sizes are for 20 inch rims......check again and let us know.

Yes you are right, so 245/35 and 255/40 seems to be the good number?

Now I just need to decide between kumho, nitto, and falken.

out of those choices I would go falken 452

Yes, go for the 245/35 front and 255/40 rear. Kuhmo or Falken would be my choice.

Well tirerack has the kumho's in those sizes($700 shipped), I can't seem to find the falkens in those sizes anywhere else....suggestions?

tires are like oil, like paint color, like wheels.... everybody has a favorite and most peoples are different. go to places like tirerack.com and enter the sizes. see what options are there and read the reviews to decide what works best for you...

I run Kumhos and so far they've been great and a lot lot cheaper.

Ok, I'm finally ordering the tires tonight, do I Need to order anything related to the TPMS system or just the plain tires?

BTW does anyone happen to have any coupon/referral codes for tirerack? Couldn't find any on google.

i'm running 275's on the rear without any issues
