I have just started riding again and my current bike is a mountain bike. I assumed that because my car tyres run at 35, my bike tyres which are smaller should run at less, so regularly rode on tyres with about 30psi. Then someone told me to read what was on the tyre wall (55-65) and pump the tyre up to the max. I have been doing that for several months now and the difference to my speed and ability to keep up with the group amazed me.

The 2nd thing I discovered was that you don't have to run knobbly tyres on a mountain bike. So I just had new tyres - called city/country - put on. They still have a bit of tread for those off dirt rough patches of road, but compared to the knobbly mountain bike tyres, they are like slicks. Now I can keep up with the front of the group.

I am learning all the time with my cycling - people who have been cycling for a while assume newbies know everything. That's why this forum is so great - everyone is so keen to help.

So maybe you could have a look at getting new tyres that are less heavy and therefore less grippy on the road.
