Yup me too, been filling up my tires to where it feels right. All depending on the conditions of the road or how I feel on any given day. Sometimes cruising I might air them soft others, good and hard and that's both, road bikes with higher pressure and ballooners; never had any problems since I was a kid. That is, not until I had a like new set of Schwinn Typhoon cord from a 1998 ballooner. IDK but about 3-4 days later, sitting in my garage with all my other bikes, one just popped. It blew right through the cheap a. cord and ripped the tread rubber about 1-1/2 inch across, complete trash. I'd trust a Kenda before a modern Schwinn tire now. Hell, the cord on the Schwinn looks like waxed paper or cardboard too.
Disclaimer: Although my garage is completely drywalled, it can get awfully hot in there. That's the only reason I guess it could have popped. Albeit, never had one but that, blow on me, in the many years I've lived here. I been a little careful on Cheap a. modern Schwinn tires since.
