Looking for some fatish tyres for a sensible price and came across 2.4" Chunky Monkeys but cant find any tech info about them, they are 60TPI carcase but specifically wanted to know max pressure. I know Maxxis actually make them and their near equivalent (Ardent) varies from 60 to 120PSI depending on model
The plan is to run them c 80PSI on a tandem with my daughter on the back, we are talking over 100kg all up - so would you trust your 20St mate riding these?

20stone is 126 Kg.......so what weight is it?
I weigh about 90Kg ready to ride and my 2.25 tyres at 28psi cope just fine, I think 80psi is a long way over where you should be!Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -

didnt do the maths but reality is nearer 126kgs I reckon, thanks for that
Just mentioned the solo comparison as often you mention "tandem" and folks think you have to use super strong Schwalbe Marathon tyres - but we have a comparatively light 20kg Tandem 70kg pilot and 30kg sprog, you have 90kg self and 10kg bike so we are only 20% up
Maxxis quote 60 or 65PSI on their website for various Ardents (which I am guessing is similar/same carcass) the 120PSI came of Chain Reaction website and is clearly way off . . .
Figure running at Max would probably be fine on something that fat, again I am extrapolating from tandemworld where folks run silly high pressures but not usually such fat tyres - and its all about volume really I guess0 -
Unless you are rolling in a straight line and don't want grip, I'd be using around 40psi as a starter and looking to drop towards about 35 to be honest.
Will you be tubeless or tubed?Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -
for a Tandem I dont think Tubeless is a direction I plan to go, tubed are quick and easy to fix on the trail
fwiw I email On One for tech info but didnt get a reply, so ordered a pair anyhow - will update when I collect them at the weekend
Correction - On One have emailed to say it is 60PSI max0 -
Chunky Monkey's are the worst tyres I've ever used. They seem to be made of plastic so there's not an awful lot of grip. They really drag, I found them slower rolling than a downhill carcass Maxxis Minion.Transition Patrol - viewtopic.php?f=10017&t=130702350

sorry to hear that, the folks on MBR seem to rate them

My priorities are (i) fat (ii) strong carcass (iii) cheap. On an off road tandem drag isn't such an issue, we won't do a tonne of miles on them and wont be pushing the grip0 -
Why not go tubeless, if you puncture (much less likely in the first place) on a trail you just bang a tube in!Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

got these on the Tandem yesterday and put a few miles of road / off road on them - my they are fat fellas
To answer my own original question these are good for 60PSI - and as others said, that was way too much in a 2.4" tyre, even on a Tandem running c120kg all up. Settled on 50PSI for now to see how we get on, may yet drop again to 45 if the side walls are happy
Fitting was really easy with Panaracer 2.2/2.5 tubes. Went on dry with no need for soap and no fighting. Easily tweaked to run cleanly, unlike many tyres I have fitted - impressed with the quality
On the road they drone like an old Landrover (which I kinda like) and have no problems in wet mud or on dry cinder - very happy with them.
One almost issue was width - there is only 3 or 4mm clearance on each side of the frame on the rear. Definitely about the fattest tyre this bike can carry0
