Because I do not have a decent pump, I've been using co2 cartridges to fill up my tires. I've found after a week or so, enough co2 has leaked out of the tires to necessitate topping them off again, which means another co2 cartridge down the drain. Is this just the nature of the beast with co2? Are the molecules smaller, or are my tubes just crummy?
Yes, I am going to buy a regular pump, but I'm still curious about this. My tubes are Kenda and I fill them to about 80 psi, I consider 40-50 "time for a refill". Would butyl tubes make a difference?
