Wow! 115 psi is the highest I have ever used (in narrow silk tubulars. I've used 23c clinchers as high as 112 psi. 25c I run at 105 max and often well under 100. But then, I am 155 pounds and I like my fillings.
I did have a clubmate borrow my Zefal HP frame pump and without too much work, top off his TT tires at 120 psi. Nice testimony for that pump since my clubmate was a skinny bike racer in his 40s. That same pump inflated every tire I used for years. That and its replacements. I went 20 years without a floor pump. (Until I started using the velcro bands fairly recently, I would periodically knock the pump off my bike. Usually though not always I had to replace them after cars ran over them.)
