How can you tell if a bike has tubeless tires or tube type tires without taking off the wheel cover hub

Check the sidewalls: Tubeless tires often have a "Tubeless Ready" or "TR" marking on the sidewall. Tube-type tires will not have this marking.
Inspect the valve stem: Tubeless tires have a larger, hollow valve stem that is designed to seal against the rim. Tube-type tires have a smaller, solid valve stem.
Examine the bead: Tubeless tires have a bead that is shaped differently from tube-type tires. The bead of a tubeless tire is designed to create a seal with the rim, while the bead of a tube-type tire is designed to hold the tube in place.
Listen for a rattle: If you shake the wheel, you may hear a rattling sound if the tire is tubeless. This is caused by the sealant inside the tire. Tube-type tires will not rattle.
Look for a sealant: If you see a white or black residue on the inside of the rim, it is likely that the tire is tubeless. This residue is the sealant that is used to seal the tire to the rim.

What are the benefits of tubeless tires? Tubeless tires offer improved puncture resistance, lower rolling resistance, and a more comfortable ride.
Can I convert tube-type tires to tubeless tires? Yes, it is possible to convert tube-type tires to tubeless tires, but it requires special rim tape and sealant.
How often should I add sealant to my tubeless tires? In general, you should add sealant to your tubeless tires every 6 months to 1 year.
How do I fix a puncture in a tubeless tire? You can fix a puncture in a tubeless tire by using a tire plug or a tubeless repair kit.
Is it possible to ride a tubeless tire with a flat? Yes, it is possible to ride a tubeless tire with a flat, but you will need to add sealant to the tire to seal the puncture.
