in the tech section there is a tire diam/speedo calculator. scroll to the bottom right and plug your numbers in and see what u get.

Runouni20xx has it right, I had the same problem when I upgraded to 15 inch tires from the standard 14 inch tires awhile back. Noticed that a one mile stretch was reduced to a 5/8's mile stretch, keeping up with traffic on the e-way and only doing 65 when the rest were doing probably 70+. Just had to put the correct gear on speed sensing unit and one mile was back to being one mile. Lots of good info in the tech section

runouni? lol wonder what that is in japanese...rurouni is japanese for wanderer or vagabond and part of the title rurouni kenshin my fav jap anime tv show. not dogging you just thought it was comical and fig i would answer the question of "where the hell did that come from?" the 20xx is from the yr 20xx a.d. in the beginning of mega man video games.
