I searched and couldn't find any info on this. I weigh 290 pounds and am riding bike, again, for the first time in 10 years. My tires are rated at a max PSI of 65 (mountain bike tires). Unfortunately, my weight tends to smush them a bit when I ride.

I'm considering new tires for primarily on-road use and want something that allows higher pressure to avoid this problem. I've had several recommendations for the Continental Town and Country, but it's also rated with a max psi of 65. Some have suggested over-inflating the tires, but I'm uncomfortable with exceeding the manufacturer's rating.

Do you think it's safe to over-inflate? Can you recommend another tire for paved roads, gravel roads, and hardpack (I have no intention of trail riding until I'm in much better shape)?
