Okay off to the pryenees tomorrow got a couple of days being guided and the rest probably on the roads, will my brand new older version RR's 2.25 be too draggy on the road?????Should I take some very old 1.8 panacers???
Pretty fast on the road if pumped hard enough, I have them on my cx bike and it flies with them on. But they do wear out very, very quickly.
Wider tyres are not slower on tarmac (or generally).
Heavier tyres and those with thicker rubber/bigger knobs etc are.
they're surprisingly fast rolling for a knobbly mtb tyre, not semi slick fast, obviously, but not too bad
I'm currently using some on a old mountain bike that i use for road training. they are great on the tarmac. but like someone up there says, they wear out pretty damn quickly
I find them pretty good too particularly when pumped up hard. (though the newer version is slightly better)
I've got some specific Mich XC 'hard terrain' tyres with almost no tread pattern and I find the difference between them & the RR's negligible.
OT: I want to try some Furious Freds now...
thanks for the advice as long as they last the week no problems
Wider tyres are not slower on tarmac - quick some one tell them before the tour starts! To think they've been mincing around on 23 mm tyres when a 2.5" would have been faster all along - doh!

See caveat about weight though 🙂
were are you going in the Pyrenees?
A good day out on the road is the Tourmalet followed by the dirt road up Pic de Midi (you top out at over 2,600m)
I'll confess that we started part way up the Tourmalet as that was where were camping (Barege I think)

I think I had Specialized ground controls on my bike? Maybe 1.5 inch hard packs
I'm sure Ralph will be fine

At speeds an mtber is likely to ride, aerodynamics aren't going to matter...and is IM says, it's only the weight of wider tyres that makes them slower (all other things being equal)
What about friction?
You are better off using wide draggy tyres for short runs. They make you fitter!
