I've been running continental touring plus 700x32 for a few months now and I am very happy with them. They only cost about $ 42 CND each. They are very flat resistent and the only flat I've had so far was a big industrial staple. Glass and stones and other crap has never been a problem for these tires. What I also like about them is that they are very easy to install/ or take off the rims which is very important if you have a flat in bad weather conditions. Before that I was running Panaracer pasela tourguards and never had a flat with them, good value and performance for the money.
