In the tire wizard under the edit menu my current gear ratio says 1.00 but when I try to put my new tire height and 3.42 gear(stock) the speedo is WAY low
and if I try to put 1.00 in the new gear spot it says invalid gear ratio.
Why wont it accept 1.00 and how do I correct my speedo?
Will correcting my speedo for new tire height help with comp mode acting up on track with my 18' rears?
