• Can anyone help with tyre pressures please?

    I weight approx 95kgs and previously I've ridden with the max rated PSI of whatever tyres my bike's sporting at the time.

    I've just ordered some new wheels with wider rims which I understand will let me ride with lower PSI for similar rolling resistance.

    I've been shown this calculator on here before:-

    http://www.dorkypantsr.us/bike-tire-pressure-calculator.html

    (Which suggests 85 for the front and 125 for the rear)

    And I've been recommended to check out the table on Sheldon Brown's site, but I can't find the table.

    My problem is that these do not seem to allow for consideration of wider rims.

    Can anyone help work out what sort of PSI I should be aiming for?

    experiment , ride one day with 140psi, next time 105psi and muck around with front and back differences.

    higher pressures for quick sprints and lower for long rides, sooner or later you get a feel for how you like it, and what works best for you and all that.

    experience creates more than just an opinion, dunnit .

    around 120psi is good for me.

    tah.

    wouldnt having wider rims give more inner volume , so youd need more psi ?

    i remember a thread on here about the A23's needing more psi because of the increased volume.
