[Gear change] [speedo]

Hi There guys
I was thinking again and if I was to change up from the stock tyres to 33s
will this have any issues with the auto box. I know it will have issues with
the speedo but not sure by how much, theres no use saying to a cop sorry sir
but I just got new tyres and they made me speed. Although im sure they have
heard every excuse when people are caught. So any ideas please let me know.
Thanks

Hi Clive
Thanks for your reply but I have that and I have a problem no not that one,
the old calculator only goes up to I think 31s. The other thing is what is a
31 or 33 10.5 in a size like the ones I have say 265 x 70 x15.
Thanks

John,
I think it's not relevant for the auto box, as the box measures engine
speed. Except for the speedo wheel circumference is not used as a
point of reference for engine control. Engine speed measured at the
flywheel and crankshaft is not affected by wheel size.
