new tires for schwinn phocus 700C Was wondering what heavy duty tires someone would recommend.  I have been using stock tires and they have blown a leak a number of times in the last six months.  Love the bike, just want more sturdy and fatter tires.  I live in pothole central and want something that can handle it.

Any recommendations?  Thanks!
Potholes cause impact punctures (also called pinch punctures or snakebites) when the force of an impact is sufficient to compress the tyre all the way to the rim.

Options to reduce the risk:


Increase tyre pressure
Reduce impact energy by reducing weight or reducing speed
Use larger tyres, which would increase the distance between the rims and potential hazards and could also be more comfortable.
Use your arms and legs as suspension to absorb some of the impact force.
Ensure your weight is not excessively biased to the front or rear of the bicycle.


Measure your frame and fork to check your maximum tyre size:


Slick bicycle tyres tend to have circular cross-sections so the tyre should be as high above the rim as their width. (Unless your chosen tyre has a thick extra layer of rubber to prevent penetration by glass and thorns, e.g Schwalbe's "Plus" models)
Regulation EN 4.10.2 "Wheel/Tyre Assembly - Clearance” states a minimum tire clearance of 6mm between any part of the frame or fork. I suggest you maintain this clearance.
