Been trying to find out if Nitto's 555R-II tires (basically, the drag radial compound with stiffer sidewalls for roadrace/autox use) would be available in 18" sizes. Currently, I think they only have them available in one or two sizes for 17" rims.
Anyway, I couldn't find any further info on their web site, and also filled out a comment form a couple weeks ago but never heard anything back. Searched high and low all over the internet and couldn't find anything either.
Today I came across a 1-800 # and called Nitto -- the person I talked to said that two more sizes for the R-II's will be available in April -- 285/35/18 and 305/35/18!
