Do New Tires Have to Have Vent Hairs?
2 Answers
Not all new tires have vent hairs. Here is some relevant information about tires: 1. Purchasing Tips: Generally, when purchasing tires, pay attention to the speed rating, load index, production date, and size. If the tire's production date is three years ago, do not purchase it because tires will age even when not in use. 2. Timely Tire Replacement: Replace tires every four years, even if the mileage driven within those four years is very low. Since tires are rubber products, they will age, and not replacing them for a long time can pose safety hazards.
I used to think new tires must come with rubber hairs, but after three years of apprenticeship with a master mechanic at the auto shop, I realized that's not the case at all. Those hairs are just residual rubber strands from the manufacturing process. With increasingly advanced production technology, many manufacturers now remove them using laser or mechanical polishing before leaving the factory. Especially premium brands like Michelin and Bridgestone - their new tires have perfectly smooth surfaces. What really matters is checking the production date code on the tire sidewall - the four-digit number inside the box indicates the specific production week. Once when installing Continental tires for a customer, the entire tire didn't have a single hair, but the rubber smell was particularly strong with current-season production dates, and they delivered rock-solid grip performance.
