he pumps it that much because it says road on the pump scale but the tyre is not rated for that much and it’s too hard on every bump.

1. Wait until it blows out
2. Adjust
Set it to 6 Bar and just let him try.

What’s the tyre spec?
Set him up with tubeless at 40 psi 😎
Are you riding the bike?
When I started commuting I put 28mm tyres on my 26″ mountain bike and inflated them to 120psi. I was an idiot.
He’s running 90 PSI on a MTB??? I use my hardtail to commute on and I run them hard at 30PSI as it’s mainly paved roadways.
Thats too much pressure even for a road bike.
Tyres usually have a recommended pressure range on them, or at least they used to!
This is way over the limit or the tyre and the rim. This is very dangerous.
Imprinted tyre limits are not a reasonable riding pressure, these are norm pressure of the tire for staying on the rim. Max tyre pressure is often more than max of the rim. Forget these numbers as a riding pressure.
The cheap, analog (pump) manometers are often way off… Cheap digital manometers are way better than cheap analog manometers. (I checked this for a company for purchasing branded pumps in china). You can get tyre pressure checkers like “schwalbe airmax pro” to not rely on the pump manometer.
As u/wendorio stated, there are a lot of videos about cycling tyre pressure. I saw one from an expert which advises pro teams. His conclusion for road and mtb: Always as low as possible without getting punctures or a spongy feeling in the curves (folding of the tyre).
Use a good calculator where you can defines different influencial factors like rim and tyre width and diameter, weight etc. like [https://csbikes.com/en/resources/tire-pressure-calculator](https://csbikes.com/en/resources/tire-pressure-calculator)
**He makes his riding feeling uncomfortable and looses grip uneccessarily with riding to high pressure…**
Silca tyre pressure calculator.
Plus their research and reasoning that vibrations and vertical movement of the whole bike+rider causes more losses than a bit of tyre deformation (up to a point).
It will crack the rim.
I made that mistake and nowhere near that much pressure.
Did it with a Hope rim too, not a generic cheap one, so it happens.
If he drives a car, ask him how he decides how much to put into car tyres. If he does the same thing, he’s lost. If he follows the sticker on the door, give him the online calculator results.
If he inflates it beyond the max pressure, he can tear the threads in the sidewalls. The tire will have bulges in the sides that will likely explode if he scrapes the side of the tire on a rock or something while riding. On my MTB, I don’t even pump the tires up past 27 psi. I keep my gravel bike at like 40-45 psi. It’s absolutely unnecessary for him to go beyond 65psi.
Tell him road stands for road bikes and not for mtb’s. The naming is ATB ( this is another word for mountainbike) then you have hybrid these are ebikes with thicker tires. And then road this is for road bikes so the bikes with small tires and tell him too read the psi on the tires. This is very dangerous and can kill you if it explodes at the wrong time.
Over 90psi in this economy ?
Gift him a proper pump. Maybe even a digital one and teach him to read the tires for guideline. Maybe even just do for it for him and let him feel the difference
