Tire presure and clydes
Today I started shopping for a new tire tube due to a flat. That got me thinking did I hit a few too many bumps on my Sunday ride. When I checked the tube to find the leak it was on the side of the tube, as opposed to the road side or the rim side. Then I started thinking about tire presure, my poor wheels, and my fat arse. The writing on my tires say to inflate to 100 to 145psi. I normally inflate my tires to about 120psi.
So could my extra weight be pushing the tire presure up too high? Are the recommended tire presures aimed more at skiny riders?
By the way, my tires are 700 23 road tires but I can't remember what brand.

You might need new rim tape.
Over time it shifts and exposes a spoke end that will puncture the tube.

Heavy people need more pressure than light-weight folks, to avoid pinch flats. That's true for clinchers, anyway.

Depending on your exact weight and compatibility with your bike frame, you may want to look into getting wider tires (700Cx25 will usually fit most road frames). These hold more air volume and will help reduce snakebite/pinch flats compared to a 700x23 at the same pressure.
By the way, when pumping up tires above 120psi, make sure both the tire *and* the rim are rated for high pressures.

You're riding in Bangkok? Between the pavement and tuk tuk drivers everywhere, my hat's off to you.
Look for the tell tale "snakebite" of two tiny punctures - that's a big indication that your tire pressure was too low.
If the roads are really bad, consider using 25 or even 28mm tires (if they'll fit in your frame)
