rear tire sizes
I have 275/40 r 20. I would like to go to a wider tire on same rim. Does anyone know how i can figure out what size i can go to without changing my speedometer ratio.

A Hennessey HPE 650 has just 245/40 R 20? That's roughly the RS package front tire, 245/45/R20, with the back being a 275/40R20. Are you sure that's what you have on the back?

Second question it appears that i can avoid throwing speedo off some. Is there a way to reflash it to match
