Was checking on prices of this tire I'm thinking of using on the 17X11 and 17X9.5 wheels I'm looking into. Found out the size tire is not available these days. Seems to be on back order from the manufacturer U.S. wide. Sumitt racing was told by there distributer its not available at this time and don't know if it will ever be.
But Nitto main office says YES, there on back order and will still be available, but no idea when.
There made in Georgia and Overseas.

The 315/35 Nittos run a smidge narrower than other brands 315/35, which is good; to fit a 315/35 on the back of a 68-72 usually requires slight trimming and/or rolling of the quarter lips, the slightly narrower section width of the Nitto's cuts down on the amount of trimming needed.

Good info, thanks. looking at 6.25 backspacing so far on 17X11 wheel. Still need to measure.
