Advice on tyres for a 109 mile charity cycle A friend and i have decided we want to cycle between our favourite football team's stadium for charity. We are starting at Wolverhampton and finishing at Bristol with a total distance of 109 miles.

We currently have cheap Btwin mountain bikes from Decathlon and plan to swap for a slightly thinner tyre. Our theory is that it will make pedaling slightly easier for us as we assume the majority of the trip will be road riding. 

The current tyres we have on our bikes are 26 x 2.0.

I have been looking at Continental Ride Tours at 26x1.75 would these fit and do you think they would be good? Not very clued up on bikes to be honest.

Thanks

Neil
Variations in this question must be one of the most asked on this site, but I can't find a good question and answer to direct you to, so I'll just answer it.

There are many rim width to tire width charts that can be looked up on the Internet. An example is on this Sheldon Brown page. It's highly unlikely that the tires supplied with the bikes are at the narrowest limit of the rims, so 1.5" tires will be fine.

If you are looking to decrease rolling resistance, go for a road oriented tire with minimal tread rather than an on/off road hybrid. Inflate to the upper end of the specified pressure range.

It goes without saying that you should have the bikes checked over and make sure the brakes and gears are properly adjusted. Also, make sure the drivetrain is super clean and properly lubed - that does actually net an improvement in efficiency.
