Default Tire size change and track times

Will going from 275/40/17's to 315/35/17's effect my track times or MPH?

Default

Your speedo will be off .1%
So if your traveling 60mph your speedo will say 60mph.

You still have 4.3" of sidewall, so you won't be loosing any sidewall. But you will be gaining some width which is a good thing!

Basically you picked the perfect tire
