ok so i have new bike which is a 650 b boardman to be exact the tyres on my old trustee steed were high rollers and tyres on new bike are racing ralphs which i found a bit lethal no grip on climbs and fatal on the downs so though i will get high rollers they dont fit why is my question this is the rim http://www.evanscycles.com/products/mav ... m-ec054039
and tyre is http://www.wiggle.co.uk/maxxis-high-rol ... ding-tyre/
i know this is a downhill tyre on an xc bike but did this with last bike no problems and i will forfeit the drag for extra grip any help would be appreciated
thanks

its not a too tight issue and i get what you saying you can pass the rim through the tyre its way oversized spoke to wiggle where i got them from and they were suprised too0 -
Do you mean that when you fit the tyre to the rim it is bigger than the stated 2.4 size and that the tyre fouls the fork and frame, or do you mean that the tyre bead is a larger diameter than rim bead seat?0

It should fit on those rims fine. It won't ride great, you're going to get a bit of a balloon type profile with the narrow rim.
The High-flyer isn't a downhill tyre but it is an enduro tyre so pretty heavy duty.
I would try something like a Continental Trail King 2.2" or Specialized Ground Control or Schwalbe Nobby Nice.
The Racing Ralph you have is the nasty wire bead, ultra hard compound plastic rubbish. The better versions are actually very good.Transition Patrol - viewtopic.php?f=10017&t=130702350 -
I was running 2 rocket rons, the newer fancy triple compound ones which I was pretty pleased with. Pretty good balance between speed/weight and grip for more XC type riding.
Put them on to replace the frankly lethal oem kenda tyres that can on the bike, I say oem as there's no discernible model name on them, I guess they are kendas cheapest tyre!
I recently replaced the rear ron as I damaged the sidewall with an older model ralph 'performance' compound, which I got cheap, but it's definitely a bit more 'sketchy' in terms of grip, it should in theory be a little faster, but I've yet to have a clean enough run to make a decision.
All these tyres are 26x2.1, the oem kendas were wire bead, (I've kept them as emergency spares) but the rons and the ralph are folding, running with standard conti tubes. Maybe have a look at the 2.1 ron.. Dunno if that's any help.0 -

Did you try to actually install the tyre? It'll take proper shape once you stick it on the rim but until then, the (presumably) folding bead will be bigger than the diameter of your wheel.0 -
