Recommended Tire Pressure for snow

Was riding in trails today in snow about few more cm/feet then.

Was sliding and had a walk bike a few times. I ride hard tail, regular mt bike. No fat bike

tires were at 50PSI
i know that is high for snow riding, but what would be more recommended and for better tractions.

Heres some pics of the type of snow we have here. Ontario, Canada, ThunderBay

We get the same type of snow here and what I found best for my hardtail mtb is to use the widest knobbies I can fit on it and set the pressure to maximum. I mostly ride paved plowed roads so studded tires set at max too.

Are those your tire tracks in pic 2? Those are Fat Bike tracks.

That looks like the snowmobile bridge at Trowbridge falls.

Depends on your tire and rim combo. Are you running tubes or tubeless? 50psi is way to high for sure. Try 30-35psi. Even less if you are running tubeless.

Lowest you can go and convert to tubeless. I ride 22-30psi in the winter.

Do I need to get special rims to go tubeless on my MTB?

Have you considered studded tyres? Loose snow, they don't offer any benefits, but looking at your pics it seems deep enough to form hard packed patches too.

Fat bikes barely leave a track... I run the tyres on the Pug at about 8 psi for deep snow.

Mtb tyres usually get run at 35-40 psi to give as much contact and cush as possible, on roads with studded tyres you can run max psi to get the best speed if you don't mind giving up some ride quality.

Tubeless tyres can be rolled out at lower pressures.

Probably not. Depends on the rim but usually most rims are convertable to tubeless.
There are two methods to ghetto tubeless.
1) the smaller split inner tube method. This requires a good rim strip, for 26" rims a 20"-24" inch inner tube and sealant
2) the gorilla tape method (which I prefer) which requires a roll of gorilla tape (needs to be gorilla tape, normal duct tape is not going to cut it), an extra valve (can be cut from a extra inner tube but can also be bought) and sealant.
Not going to go through the whole method here since you can easily google the methods.
Inner tube ghetto tubeless or
gorilla tape ghetto tubeless or gorilla tubeless

50psi is way too much. Right off the bat I'd say go to 35, or let some out see what you think, then try some more. Tubeless will get you lower for sure like 25, but you might not want to deal with it. Although IME ghetto tubeless is easier than you'd think and works really well. google it.
