Why Can't the New Tire Be Inflated Due to a Large Installation Gap?
2 Answers
Here are the reasons why the new tire cannot be inflated due to a large installation gap: 1. The air inlet hole of the valve core is blocked: Unscrew the pressure nut, remove the valve core, detach the valve rubber tube, and use a thin wire or needle tip to clear out any dirt or debris. 2. The valve rubber tube has melted and blocked the valve core hole: After removing the valve core, clean it with gasoline or similar solvent, then use a thin wire to clear the blockage. Once confirmed to be clear, replace it with a new rubber tube. 3. The air passage is blocked: Extremely cold weather may cause the moisture in the valve rubber tube to freeze, blocking the air passage. Remove and heat it to melt the ice, then shake off any water droplets. 4. Issue with the air pump: Check the air pump or try using a different one.
Recently, I also encountered a situation where the new tire couldn't hold air after installation, mostly due to air leakage caused by sealing issues between the rim and the tire. The most common reasons include: uneven rim surface or rust accumulation preventing the tire edge from sealing tightly; the tire itself being deformed during transportation or installation, creating gaps; improper installation techniques, such as not using professional tools or lubricants, resulting in the tire not being fully seated in the rim groove; or a loose or aged valve stem causing a leak. I recommend first removing the tire to thoroughly clean the rim surface, ensuring it's free of grease or damage, then reinstalling it to try again. If the issue persists, check if the rim is deformed or cracked. If necessary, take it directly to a repair shop for a pressure test to locate the leak. Never force inflation to avoid tire bursts. Addressing such issues promptly can prevent driving hazards.
