What to Do When a Tubeless Tire Won't Inflate?

Tubeless tire inflation issues can be resolved by: 1. Replacing the valve stem; 2. Cleaning dust from the valve core; 3. Repairing the tubeless tire. A tubeless tire consists of the carcass, cord ply, and tread. The carcass is relatively soft, while the tread has greater rigidity. The middle cord layer reinforces the carcass strength and maintains shape, often incorporating metal wires to enhance the tire's elastic performance. Characteristics of tubeless tires include: 1. Slow air leakage when punctured, allowing the vehicle to be driven to a repair shop; 2. Excellent heat dissipation and long lifespan, as the absence of an inner tube and flap reduces friction-generated heat between the inner tube and tire cavity. Direct contact between internal air and the rim allows heat to dissipate through the rim, preventing excessive tire temperatures and reducing blowouts to extend tire life.
I've fixed many issues with tubeless tires not holding air, and the common causes are stuck or damaged valve cores. First, try loosening the valve core with a wrench tool. If it still won't hold air, the issue might be due to aging or cracked rim seals causing leaks. Spray some soapy water along the tire edge and valve stem—bubbles will indicate the leak point. Small cracks can be temporarily sealed with tire repair glue, but major damage requires switching to a spare tire. Prevention is also crucial: check tire pressure every two weeks and maintain the standard value to reduce wear. I always keep a portable air pump and a tool kit in my car for emergencies—DIY fixes save time. Tire damage is often caused by punctures or corrosion, so regularly inspect the rims for cleanliness and rust to ensure long-term safety and peace of mind.
