So, while 35 min isn't required for pavement, your point that weight should be considered is worthwhile.
At your weight using 23's was not idea, if you add 240 plus another 20 for bike and kit and accessories you should have been running at least 150 psi in the rear and no tire is rated for that pressure! Even at your now 224 plus the 20 you would still have to use at least 140 psi in the rear, very few tires are rated that high. The very smallest tire you should be using is a 25 and that's marginal!
