carlos... the tires have same section width so to my understanding should be good for a go, wieght difference maybe a pound per tire?
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
