Those tires might not grip well on wet roads.
I had a nasty fall riding in the rain last summer.
I was about to make a right hand turn, wanted to slow down a little, so I only used 1 finger, locked up the rear wheel and the bike (20" dahon with those tires) spun around instantly, putting me on the pavement.
My right foot gripped the pavement perfectly, (5-10 shoes) and I ended up with a rather painful knee sprain that had me limping around for a few weeks.
I switched to
Maxxis DTH tires that have substantially more traction.
