How high can I over inflate my tires? (lemmy.ml)

I frequently do large grocery trips with my bike and the rear tire always looks smushed even at 80 psi (26×1.95). I was thinking of over inflating another 5-10 psi but not sure if this is going go lead to other problems.

Generally, if bike+rider+groceries > 250 lbs, you may to see some deformation of the tires at recommended inflation levels. Don't overinflate, that just makes the tires/tubes more stressed out under heavy loads. Deformation is OK, just be careful of where you're riding when hauling a heavy load. Hitting a hole or something will be more likely to give you a flat and bust up your rim.
