What's the optimum PSI?

[E Moses]

My bike has 26" x 4" Kenda Juggernaut fat tires, I'm 83kg and my daughter is about 21kg. What's the best PSI For me alone, and for both of us together?

20 PSI is my current setting. I ride almost exclusively on paved roads.

Thank you!!

Irrelevant information, OP has 4" tyres and your chart only goes upto 37mm.
As my old teacher use to say " if you haven't got anything useful to say, then your better off saying nothing "

you can go as low as 12 psi but if you have suspension fork, for road use, 20-25 psi will save a fair bit on battery.

Yes, the bike has adjustable/lockable 80mm suspension fork and I tend to leave it on at all times.

The chart doesn't have the right measurements...

Some rolling resistance figures on this link.

Seems the Kenda tyre is a poor performer in fat bike terms, but 20psi will make the best of a bad job.

Could be worth changing to Schwalbe Jumbo Jim when the Kendas are worn out.

Ah, the good old "I love upgrading"!! I had Kenda tires on my full-suspension mountain bike and they endured everything I threw at them. Still in a good shape. Given my e-bike riding style, I'm certain the current tires will be just fine and will last for a long time.

To be fair he was on about rolling resistance not how long they will last
I also thought you were on about the tyre pressures to make riding easier especially on the road
Tyre pressures are to a point a personal thing obviously in the parameters of the tyre
So if I was you look at the side wall and pump them up to the max recommended pressure and go from there
They will definitely roll better harder are or you after comfort

sorry about the chart didn't realise but I will say with fat tyres you will get better speed and durability with tubeless and you will also get faster speeds with less pressure

In case you haven't seen it, here is some real resistance data on Kenda fat tyres, PSI effect is dramatic with this fella! Max recommended pressure is definitely a good idea if you want to reduce resistance
