Tires too narrow for the wheels?

Hello,

I know of the debate of 'wider is better', but I got mixed answers from various people regarding the maximum tire width for a certain wheelset and wanted to know the opinion of cyclists from here. I am drooling over this wheelset:

and would like to use the 28 mm wide tires from Continental GP 4000
( https://www.continental-tires.com/bicyc ... ix-4000-s2 ) - 700 x 28C.

Do you think there could be problems like tire running off the rims or other kind? I'd like to use close to maximal pressure allowed for the tire.

    Surely the point of using wider tyres is that you can run lower pressures?

    No. Lower rolling resistance and better braking. Wider rims for the same tire provides for more precise riding as well, stiffness and - why not - better looking.

    Should be no problems running 28mm tyres on those rims. Plenty of people using similar for cyclocross and the like.

    I agree with the other bloke about tyre pressures though.

    On 20C rims you can run 25's or even 23's without any problem.
    28 's are fine.

    Hi guys,

    thank you for the replies. One question - my current wheels (MAVIC Crossone Disc) uses 6 bolt discs, but the wheels above seem to use center-lock. Would that request other changes besides the discs?

    What is the 'maximal pressure' for 28's?
    I'm sorry you don't believe in miracles

    No. You can either buy centerlock rotors, or an adaptor to use your existing rotors. If you are on 160 rotors I would buy new rotors - mountain bikes use that size so there is loads of choice for £15+ a wheels. If you are on 140s its more like £35 a wheel because you will need something like Shimano icetech - which are admittedly very nice - but I would get the adaptors as £70 on top of what you are already spending on wheels is steep... (should cost about £20 for both wheels for adaptors)

    You can have a look on the link provided for the tires, there you can find maximal pressure for various sizes of this tires.

    As for the discs: I am using 160 mm, I will just change the discs, then.
