Tyres

[lamcote]

Just had an interesting chat with Camskill about some new tyres.

The chap said it's best to avoid tyres with good fuel efficiency rating and try to get tyres rated as F for fuel economy.

Apparently the manufacturers use soft sidewalls to reduce rolling resistance and the same tyres are often available with different fuel efficiency ratings, if so always go with the worse fuel efficiency rating if you want decent handling.

Have heard similar.

Maybe lost in translation. But something does not sit right here. (For me)
Shirley this is down to tyre compound rather than sidewall construction.
Thinking yoko ad08r here. Sidewall = not soft. Rolling resistance = not reduced.

... Don't call me Shirley!...

Isn't it the other way around, like how low tyre pressure creates significantly more resistance than higher tyre pressure.

Just think of when you used to ride your bike on a flat tyre. Very hard. Then inflated it and it seemed to roll forever.

Surely the same concept applies to compound hardness.

I certainly agree about going for a less efficient tyre for better grip.

I imagine the compound is the biggest part of the reason but there will be an effect from the "give" in the tyre as one with better rolling resistance can deform slightly when meeting an obstacle that would otherwise take energy to overcome and go over.

Anyway, its a moot point, everyone should just buy AD08rs, end of!

Well said!
