I just found this list where they have rolling resistance data of the 3 tyres I was looking at ( the city jets/ Hurricanes/ Marathon tyre- although I'm not sure which marathons as there are like 5 of them and some aren't that good with rolling resistance)
helsinki.fi/~tlinden/rolling.html
So seems like the Hurricanes has almost the same rolling resistance as the City jets but with the added more grip bonus?
the Marathons seem to have a really huge proportional rolling resistance based on that table compared to city jets for example- but than again I'm not sure which marathons are they talking about?
If the Marathon Greenguards (those who have one of the lowest rolling resistance) would have the same rolling resistance as the Hurricanes than its a clear choice because the greenguards are better protected and doesn't costs that much more?
