Not sure what the best method is for wheels with one valve stem, but 949 wheels have two 180 degrees apart. So, you could push Nitrogen in one and purge out the other. This would give the best chance of high Nitrogen content.

 

Tirerack has RS-3s coming in tomorrow morning...

 

I am a STR n00b trying to learn more daily. So bear with me...

Josh - I know you run 17x9 6ULR and so do others, why is the 17x10 +72 with 275's not popular? Is there a fitment issue on these on the fronts or rears? I figure there is good reason - like pulling fenders or removing fender liners etc - just curious. I would think it would also clear all brake kits too...Thanks!

 

We are limited to 9" wheels and 255 tires in STR.

 

STR rules dictate 9" wheel width max and 255 tire width max.

 

^^^ what they said.

 

Wow, fast replies...I knew there was a reason. Thanks all.

That is going to make more than a few folks very happy.

 

I'm thinking about trying the Federal RS-R 595s when I buy STR wheels. We have a local here in MN who's doing well running them on his 2011 STI. The RS-3s are just no good in MN because it's too cold at most of our events to ever get heat into them, and when it's cold AND raining they're just about useless. Can't argue with the price either, especially compared to a set of Star Specs.

Forgot my other question, at stock ride height do the fender tabs still have to be rolled to clear a set of 255s?
