I bought mine through Newstalgia Wheels and had them shipped to Norway.
The 315 should be available, see http://marktg.toyotires.com/file/30029.pdf

Steve, how are the R888's on the street?

Im looking for a tire that will wear pretty good on the steet. I plan to drive my truck only on the nice days to work, and shows. Then i want to hit up locak Auto X's.

Guys one more question how mutch drag do these tires have!!!!.
i alredy have a disasteres 560 hp/577lbs feet of torque fuel consuming 461 ci pontiac engine.
with a 0.67 overdrive ,and with a 3.42 rear ratio i save 30% fuel econemy. installing a Vari lift system should give me another 20% econemy. (below 3000/3500 rpm) .we are also going to install one ecstra 10 ore 15 gallon fuel cell in the boot along the 19 gallong DSE tank for this 3000 mile road race.

So as mentiond before we need sticky tires and it seems the ones above are the ones to go for, but im consired about the drag a bit .....also where can i get mischelin pilot sport 315x35x17 tires and how mutch are they , just heard they have the least drag and save up to 5% fuel econemy compeard to other tires.. any feed back!!!!!!!! about them ....
