Tire pressures help training?
Would training at lower tire pressures be an effective way of training? It seems intuative that lower pressures would increase resistance and provide better work. I live in an area without hills, all flats.
I am training with tires @ 90 psi, I would think that when I change wheels and load tires to 120psi, I will benefit on raceday. Is this ignorance? What do you guys think? |

Re: Tire pressures help training?
The easiest way to increase resistance is by shifting to a different gear.

Re: Tire pressures help training?
How about simply riding a bit harder? In the end, on a given day for a given duration only a certain power can be produced with is unaffected by gear, grade, tire pressure or head wind.

Re: Tire pressures help training?
Maybe hard to believe, but actually, the opposite is true: lower pressures have LOWER rolling resistance, as the tires don't have to expend as much energy rolling over irregularities in the road surface. Use other methods of training to get stronger, not by varying tyre pressure.

There is no set answer to this -- it depends upon the surface and the tire construction. Certainly on a smooth surface, I don't ever remember seeing test data where higher pressure did not provide lower rolling resistance, a practical application being railroads. |
