It is an excellent tire. But, depending on the rim profile, wait till he tries to mount them...

You need more bikes.

Back in the day when I was still running 23c tyres and you had to download websites to read them, I just ran them at 90 psi and that was a plenty harsh enough ride! Now I run 30c and 32c tubeless at around 60-70 psi. I weigh 175 lbs.
If you have clearance for 25c I would take those and experiment with lower pressure. Unless you weigh a lot more than me, 90 psi should be more than enough.

You don't believe me? You put the pump on a Presta valve and don't get a pressure reading, right? Because the pump head doesn't open the valve. On a Schrader valve the pump head opens the valve and you get a pressure reading as soon as you put the head on the vavle. When you pump up a presta valve the air from the pump pushes the valve open, air goes in. When you reach the bottom of the stroke/stop pumping the pressure in the tire is greater than in the pump and the valve closes under that greater pressure. Thus no air is lost.

those are not my words. in fact I was accepting your answer, but still curious. I will run a test when I find my high pressure gauge. just realized my bike bag had a low pressure gauge cuz I've been riding my MTB a lot this past year. BTW all my bikes use Schrader valves

bought a new Milton patented pencil style gauge 20-120 psi. pumped the road bike rear tire to 100psi, pencil gauge reads 98, not bad at all! pumped the front to 90psi pencil gauge reads 86, again not bad at all. when I use the pencil gauge I can hear/feel some air loss as well, so I don't usually measure the tires after initially pumping them. all in all, not losing as much as I thought. I think you are mostly right, most of the air I hear & feel is coming from the hose & I have a long hose. the pump is a craftsman. adapted an old hose & chuck that I liked from a previous pump. I find the Craftsman gauge to be reliable
related, after pumping the bike 2 weeks ago, 2, 25 mile rides during that time, the tire pressures today were in the mid-70s. I guess it pays to pump them fresh, once a week maybe, if I'm using it regularly. not gonna pump it if I'm using the MTB of course
