i bought the s-02's at a local america's tire in 225-50-16. the only reason they are still available is because they were factory equiped on the older s2k's, this is what the manager of that america's tire store said at least, thats why he always has one set in stock. he also mentioned that they are wider than most 225's, when i went home and measured, they were closer to 240, 237 IIRC. they are very sticky and i hope i have some success with them at buttonwillow at mazdafest in 08.
