The speedo in my '99 Sub is off by about 9% (verified by GPS x2).
I'm guessing the PO had it calibrated when running the (cheaper) 265/75/16's "C"s... since that's what the spare was (had been there, unused a LONG time) & that's about the difference between the stock 245/75/16 (10 ply) I'm running.

Just want to confirm/change the tire size... tired of doing the mental conversion!

:beer:
 
Tru Dyno Sports in Conover should be able to help you, if you want to come this far... plus you could get that thing tuned while your there... There are a number of guys that have had him tune thier buggies...
