- tyre width Q for fat bikers?
To ride the groomed nordic trails here through the winter, I need a tyre stamped with 3.75 as a minumim.
My Scale plus frame has a measured 3.75″ minimum clearance between the seat stays and the 34 Plus fork a good 4″ clearance between the lowers.
So, I can either build a 26″ boost hubbed wheelset with BR710 76mm inner rims OR use an existing boost hubbed XM551 40mm inner rimPosted 6 months ago
Knowing nothing about Fat or 27.5fat tyres, can anyone give me an idea as to what minimum 3.75 wide stamped tyres come in under their measured with? I guess I’m looking at 3.8 and 4.0 tyres?
I recall there are some 26×3.8 tyres that measure 4.7″ so I assume things could be all across the board.
My 26″ dillingers are nominally 4’s but are 3.75 on 65mm rims. (Just measured now). They are also studded which I like. We have the same “rules” over here in Canmore and it seems strange. If the snow is wrong you’ll leave a groove no matter what width you are running…..
Are they actually on Nordic trails or just lost lake area in Winter? We’re just on the trails but they still insist (although never been checked)Posted 6 months agodovebikerMember
Putting a wide tyre on a skinny rim will results in lots of ‘squirm’ at low pressure and sometimes you need to go <2psi to maintain traction on snow. If you have the option of running a slightly wider rim and more aggressive tyre upfront it helps as it compacts-down the snow – the rear is just ‘pushing’.Posted 6 months ago
