I have some Kenda tires (not sure which ones) on my Joe Appaloosa. I think they are 45 wide. I pump them to 65 ( I think that is the max) and don't pump them up again until they get that squishy feeling, then pump them up again. I do like them a touch less than the max, but much more than squishy. I'm not sure what pressure that is. Still fairly firm though for me.
