My experience of 24" tyres.. Front: Spesh Roller 2.5" big profile, great grip, ok wear rate, 650g, paper sidewalls! Tioga Comp3 2.1" well narow, mine was narrower than everybody elses, does the job, cheap, look cool too. Halo Choirboy lite, 2.3" bit overkill, like 980g or something, good beadlock, ran one on the rear for a while, grips ok in the summer, pinched it a bit, not too bad. Rear: Maxxis 2.5" heavy, 1150g? pinched it once, but I'm pretty harsh and pinch everything, big tyre, felt well crap at first, 'cos of extra eight, but they are the best tyre for trials. Tioga Factory DH 2.3" Look great, pinch like anything, pinched it 4 times in a day, grip ok when new, in dry, wear down pretty quick, fold unless rock hard, I think i was 50 psi I ended running mine at = no bouncyness obviously...
