Independent of the manufacturer of my new road bike, I wanted to ask if I am overkilling the purpose or intent of 700x32 tires by using 100 PSI. The air volume is greater for 700x32, so I believe the additional volume will cushion more than e.g. 700x26 and that I don't need to go down to e.g. 70 PSI to provide more cushion. I am not sure the rolling resistance or drag/friction/contact area when using 100 PSI will be significantly lower from that when using 70 PSI.
Specifically, with regard to manufacturer, I was able to purchase an unused 2021 Trek Domane SL7 that was still in inventory at a great savings. The original 700x32 OEM Bontrager tires had a max PSI of 70. But I like Conti GP 5000s so much (max PSI 102), I put a set of 700x32 on the carbon wheels in about 30 minutes yesterday (without a prying tool) and during a ride the bike felt considerably faster and lighter.
Should I knock down the PSI in the GP 5000s to 70 or so for a more cushiony ride, or is leaving PSI near 100 okay?
