IF scorchers they are any bigger than marathons they will not fit.

My bike with standard Mezzo or marathans tyres on has marginal clearance from the mud guard at the rear. I do a small regular run over about 100 yards of muddy areas on the school run. The rear wheel/mudguard area gets clogged up even with this small run. This even stops the bike wheels from turning if twigs ect get wedged.

At the front mudguard there is more clearance, so maybe ?

For softening up my bike I sometime use a spare mezzo seatpost tube with a sprung saddle. I am looking for try a cheapish suspension hub for the front.

A suspension seatpost would be great for this option if anyone has an idea. Maybe welding a tube to a thudbuster?
This would add to one of the few advangers of being able to quickly lift out the mezzo post.
