    tire and rim widths?

    Okay...I've read the Sheldon Bible about this but have never had any problems running my Conti Grand Prix 20mm tires on 13-15.5mm wide rims...anyone have any experiences to the alternative?

    What kind of rims do you have that are 13mm wide?

    Sheldon's guideline is just a caution, plenty of people (myself included) has exceeded the recommened values.

    I figured as much...I just wanted to be cautious...the new wheels (Khamsins) are 15.5mm wide and I feared pinch flats. The Contis' max air pressure is 150 and I run them around 130 rear and 110-115 front.

    On one of my bikes, I'm running PR2 23s on 21mm wide rim interior width. 29er crowds used 50+ on Ksyriums and Zipps (17s) without a problem.
