Guys - Can I fit 2.3in Tyres to my Rockhopper without them fouling on the Forks or the frame?

Standard width is 2.0

I know there's probably not a definate fit and its more of a trial and error as each tyre is slightly different in size.... but suggestions or previous experience would be appreciated!

    What does your clearance look like now with the 2.0?
    You only need two tools: WD40 and Duck Tape.
    If it doesn't move and should, use the WD40.
    If it shouldn't move and does, use the tape.

    Just out of interest - what type of riding are you planning on doing with the Rockhopper that would require 2.3in tyres?

    Try borrowing a mates wheel and fitting it into your bike, that way you can find out for certain whether or not it will work and won't cost you a thing!

    If its the standard spec tyre, it says 2.0 but it is actually a fair bit bigger, tyres vary from manufacturers.

    I would say more than likely you would be fine with some 2.35 and would reccomend the maxxis high roller for a decent budget tyre. this i find is the perfect tyre width for trading rolling restistance for grip on the very rocky rooty welsh trails.

    alot of narrower tyres are just skittish in my local conditions(plus big tyres = way more fun on the downs)

    No idea - Just seen the Continental Speed King Tyre on Wiggle for £11.96


    they come in 2.1 and 2.3 variety, and just wondering if it's maybe worth going for the 2.3 width, as some people have made reference to certain tyre types being narrower than they are described?

    In the end probably 2.1 would be the safest bet! :P

    It's gonna be tight. You might get a 2.3 on the front no problems but at the back check how close the seat/chainstays are to your existing tyre, and also the line of the chain in the granny ring. I can squeeze a skinny 2.1 XC tyre on my '2.0 max' Proflex but there's like 3mm clearance between the swingarm and the shoulders of the rear tyre.

    Did have 2.2 Mountain Kings on my Stumpjumper HT - a bit of room to spare. Conti tyres always come out thinner anyway (if that's what you plan to use). Now gone the other way and got 1.8s!

    Depends on your local terrain though for tyre choice.

    If i was in the midlands or where ever i'd use skinnier tyres, it's not that rocky, not really rooty not very steep either so you more interested in rolling speed.

    But i don't it is steep and rocky as hell here, so a bigger more solid tyre doesn't puncture so easily and grip well :)

    Yeah I'm thinking the terrain here is quite rocky and steep especially in the likes of Golspie at the top of the run, but a 2.1 tyre is still wider than my 2.0 fast trak LK's which are uselss on anything slightly loose ground!

    2.1's are probably the way to go - and the above tyres are only £24 in total for the 2 so its not a big loss if they turn out to be cr@p :P
