Questions about tubeless tires I keep getting a lot of pinch flats even though I've pumped my 26x2.00 wheels to 280Kpi (65psi) and I've been thinking about converting to tubeless. But I don't have both tubeless ready tires and rims. What if I buy just the tires but use my current rims, will it work?
Without tubeless ready rims it will be hard to get a traditional tubeless setup to work.

What could possibly work might be a ghetto tubeless setup as described here:

Altough this is specific for mountainbikes. On a road bike I would suggest getting proper rims for a tubeless setup.
