Message I posted this in the tech section, but there's been no response. Emailed Coz as well, but he wasn't sure. Is it possible to change the speed pinion gear so that the speedometer reads correctly with a 45 series tire?

I went from stock wheel/tire size to 245/40 and definitely could tell a difference in the ride quality. Speedo was off ~2-3mph as well. With the 45 series tire, it's going to be 5mph off.

Any advice?
