Tires 4120 R4 Tires

[MT. Sparky]

Does anyone know if My 4120 with R4 tires has tubes in the rear tires. I got a front flat and it does not have a tube. Thanks

Look at the valve stem. If it is the same as the fronts it will be tubeless. On a tubed tire the valve stem would have threads on it with a nut holding thru the hole in the rim.

Or look on your tire most state what type they are.

On tubeless the valve stem is secured in the rim with a hex-head metal nut. Tubes usually have a plastic knurled nut holding the stem.

4720 - front and rear tubeless.

I put goo in them - have some leaks.
