Minimum tire width to avoid snake bite I have a road bike with 22mm tires. They are super fast, but I get them punctured a lot.

I have decided to switch to wider tires to avoid snake bites, and I was wondering what would be the minimum recommended width of the tires.

I am fully aware that I may not be able to fit just about any 622 ETRTO tire (700c) due to cantilever brake clearance; which is why I am asking about the minimum.

UPDATE: In the end, I went for Continental Grand Prix 4-Season, 25-622, and never looked back - these are (expensive, but) AWESOME!
I doubt you're getting snake bites in a 22mm tyre unless it's very low on air. Even then it's not likely. 

Snake bites have a distinctive two-hole pattern so you can check. It's more likely that you're getting ordinary punctures. There may be tough 22mm tyres, but most this thin are designed to be light. There are certainly anti-puncture options at 25mm which should fit, but may be a touch slower.
