For a long while there, Dennis Kirk's website published specific weights for a lot of brands/models of tires that seemed pretty accurate, but they seem to have deleted that info recently.

go ahead and down vote this objective list of tire weights lol
I mostly use bridgestone..really like the x30 front x40 rear combo for my track in the warmer months when it packs down by lunch time..but a 120.bridgestone x40 rear for my 450.is indeed a very heavy tyre...I run a 110 for soft terrain on it though
Here's some Kenda weights:
Millville II (2) 110/90-19 12 pds 2.3 ounces (5510g)
Millville II (2) 80/100-21 8 pds 10.97 ounces (3940g)
Washougal II (2) 100/90-19 11 pds 10.95 oz (5300g)
Have there been any new ideas regarding tubeless setups for MX in recent years??

Yes, putting helium in your tubes may make the whole assembly an ounce or 2 lighter when on the scale, but doesn't change a thing when your tire is tracking along the dirt and the suspension is soaking up peaks and pushing the tire into the troughs.
Save your helium money and spend it on more new tires, that will make a difference!

I also weighed a 110/90/19 sc5 med and got the same number reported earlier in the thread.
Does anyone have any mousse weights?
It has to do with the thickness, but equally as much with the rubber compound of the tube and if there’s something between the tyre and the tube, like baby powder. Pinch flats are not only a pinching, but also a tearing motion and if there’s something in between tyre and tube that reduces friction, it’s much less likely to cause a hole in the tube.
I ride mostly hard pack tracks and since I use thin, high quality tubes (Michelin are great) and put a lot of powder in, flats became very rare.
How much baby powder are you putting in?
Couple years ago when I was still running tubes, I’d order them off the OE Yamaha parts fiche. They were usually Japanese-made Dunlop or Bridgestone.
I put a good amount in the tyre and roll the tyre around until everything inside the tyre has a light coating. Then I take a hand full and rub it on the lightly inflated tube until it‘s coated as well.
Yeah, tyre soap work great. You‘ll see that the baby powder will make tyre mounting easier, bc the tube can move in the tyre. And inflated the tube a bit before you pop the tyre on.
If the bead is squeezed in it will fit up east. Sometimes need to flip the wheel over and push it down intermittently. I don’t trust people not to fit my tires without the dreaded bead tearing noise.
I also think tire lubes can contribute to wheel spinning on rim.
I don’t use air valve lock nuts either.
Good idea on the Yamaha fiche for the genuine tubes, Broseph
