Just picked up my new 2014 Trek Domane 6.2 road bike from a specialist bike shop,and noticed the bike has been fitted with 700 X 23C on the front and 700 x 25c on the rear.
Please confirm if this normal practice ,and if it is what is the reasoning behind it :?: or is it an error on behalf of the shop

    There are lots of schools of thought on this, and there is no right or wrong answer.

    Some people run wider at the back, some run the same width, and some run wider at the front.
    Red bikes are the fastest.

    Sounds like a smart choice for UK use.
    Whats the solution? Just pedal faster you baby.

    Wider tyre on the back is supposedly going to give you a more comfortable ride. Wide tyre on the back of gp bike is so you can get the power down when your coming out the apex of a bend.

    Continental actually sell a set of tyres (Force/Attack) with 22 front and 24 back. Tread is slightly different too.

    I do this on several of my bikes, usually with a 25mm front and a 28mm rear. Much more comfortable ride whilst still fairly sharp handling.

    More weight on the back so either more pressure in the same sized tyre or similar pressure in a bigger one.
    Conti Attack and Force use different compounds as well as size.

    23/25 front/rear is good

    better traction, comfier

    25/25 even better
    my bike - faster than god's and twice as shiny

    On mountain bikes you typically have the wider tyre at the front to get more grip. The last thing you want is less grip at the front. However not sure about road bikes as you don't really want to be sliding either end of the bike!

    Been fitting 23/25's for years. Coupled with latex inner tubes, they roll rather like tubs.

    Don't knock it till you've tried it. I dare say that if I was still racing, I wouldn't carry that much rubber and forgo some comfort, but you can pump them a lot harder than say 22mm tyres too and still get a comfy ride which is a bit of a good trade off.

    As has already been said there are loads of views on this. I run 25 on the front and 23 on the back. My reasoning is that the bigger tyre on the front means better grip and traction for steering. Hopefully reduces speed wobble...

    Come on admit it - it's not speed wobble, it's being plain drunk.

    You cannot ride a bike while properly drunk - I've tried :P

    You get on and then you're on the floor.

    I beg to differ earthling, in my student days, I found cycling easier than walking when drunk. Strap the feet into the pedals and the bike took on a life of it's own; knowing where the Kebab shop was and where home was.
    Walking required numerous lamp posts and railings to keep one's balance.

    If it's a 6 series then is it a custom job, or you've otherwise specified those tyre sizes? Because Trek Domane 6.2 bikes sold as per spec come with Bontrager R3 Hard-Case Lite, 700x25c front and rear. If you haven't got these or they are different sizes then something has gone on, as that's not normally how the bikes are supplied.

    This is completely separate from the debate as to if 23/25 is a good strategy.

    The bike was a PROJECT ONE BUILD - Tyres as spec -
    Thought it funny not the same size - hence the original question.
    Think I may go back to the TREK SHOP and ask the reasoning ?

    I'm running 23/28 out of necessity (destroyed rear tyre only had a 28 spare). I thought I'd like it because I liked 1.2/1.6 on my old rigid but now the back end feels squirmy but kind of comfortable and the front feels too hard. NVM my Vredstein Duocomp reds turned up today so back to 23/23.
    I used to just ride my bike to work but now I find myself going out looking for bigger and bigger hills.

    Right the reason I ask about project one is at that stage the bike shop would probably have the ability to specify which tyres are fitted. Are they clinchers or tubeless? Either way it seems something has gone wrong if you haven't asked for this setup.

    Again, there's nothing wrong with it, it's just the question of why it has happened.

    Mark - checked at the TREK store and the 23 was fitted in ERROR - it will be changed for a 25 after the 6 week period.
    ps the best TREK bike I have owned - well worth the money spent
