Is the 909018 3.00-18 tire universal?
2 Answers
Not universal. The 3.00-18 tire can be interchanged with flat tires 110/90-18 or 120/90-18. Here is relevant information: 1. Automobile tire structure: According to different carcass structures, automobile tires can be divided into pneumatic tires and solid tires. The vast majority of modern vehicles use pneumatic tires. Based on internal air pressure levels, pneumatic tires can be categorized into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. Low-pressure tires are commonly used across various vehicle types. 2. Usage classification: Tires are classified by purpose, including truck tires, passenger vehicle tires, and mining tires among others. In addition to specification markings on the sidewall, truck tires must also indicate ply rating.
When I used to help change tires at the bike shop, I encountered similar issues. The size 3.00-18 is quite straightforward: 3.00 refers to the tire width of 3 inches, and 18 means the rim diameter is 18 inches, mainly used for scooters or electric bikes. However, whether it's universal or not depends on whether the rim width matches the tire. For example, if the rim is too narrow or too wide, the tire will deform after installation, affecting ride stability. I've seen cases where people installed tires incorrectly, leading to blowouts, which is extremely dangerous. I recommend measuring your rim width first and then checking the tire specifications; '909018' might be a specific model—don’t swap it casually to avoid incompatibility. Always inspect tire wear regularly when riding to prioritize safety.
