euro... mpg # calculated with us gallon which is 3.78l, i think imperial is 4.18? also done on my regular 360km route averaging 100km/hr, has a lot of long 6-8% grades. on a different route i took last summer it seemed to do better.
thanks for the welcome guys
When I went 1-size-up from stock, I think it was a 1+ lb increase per tire (for a 2% gain). When I looked at 2-sizes-up-from-stock, it was a 3+ lb increase per tire (for a 4% gain). Because of that I only went 1-size-up-from-stock.

Depending on how you look at it, the extra lbs hurt you in acceleration but act as flywheels during coasting (right folks?!?!?).
