For muddy CX races or a ride which will be in thick mud, you need a tyre that offers maximum traction. Look for a thick tread with mud shedding capabilities. A wider tyre will allow greater grip & puncture protection, but will weigh more. Choose wide tyres for grip, narrower tyres if you’re chasing a podium spot. To get the best traction in the wet, you need to run your tyres at a lower pressure,racers often opt for tubless tyres, which prevent the chance of pinch flats at a lower PSI.
