I have used for 10+ years the Specialized All Condition Armadillo Tire. Very puncture resistant.
DURABLE PUNCTURE-RESISTANT TRAINING / ALL SEASON PERFORMANCE
Our All Condition road tire does absolutely everything well, making it one of the best all-around tires available anywhere. Proprietary Armadillo flat protection assures riders can cover as much terrain as they want and never have to worry about punctures. The lightweight dual-compound siped tread blends all-condition traction even in wet conditions with exceptional wear. Top it all off with our motorcycle-inspired dual radius design (DRT) that minimizes contact in straight lines, while maximizing contact surface and traction in corners.
