What is the compatibility for 80/100-18 tires?
3 Answers
3.00-10 and 90/90-10 are both compatible. 3.00-10: 3.00 indicates a section width of 3.0 inches, 10 represents a rim diameter of 10 inches, and the "-" denotes a bias-ply tire. 80/100-10 means a section width of 80mm, 100 refers to an aspect ratio of 100%, the "-" indicates a bias-ply tire, and 10 stands for a rim diameter of 10 inches. Below is additional information: Tire dimensions: Another common way to express tire specifications is through formats like the widely used 205/55R16. In this sequence, 205 represents a tread width of 205 millimeters, 55 indicates the aspect ratio (meaning the sidewall height is 55% of the tread width), and 16 shows that the tire can be mounted on a 16-inch rim.
I've dealt with many tire issues. The size 80/100-18 is commonly used for small vehicles or motorcycles, with a fixed rim size of 18 inches, so compatibility mainly depends on width and aspect ratio. The combination of 80mm width and 100% aspect ratio (meaning the tire height equals the width) is relatively rare, but other 18-inch tires with similar widths can be partially compatible, such as 75/100-18 or 85/100-18, since the rim size is the same. It's best to check the vehicle's manual, as some models allow slight width adjustments within a 70 to 90mm range. I recommend starting with the manufacturer's recommended size—don't compromise safety by choosing unsuitable tires just to save money, as this can lead to uneven wear or affect handling. Regularly check tire pressure and compatibility during maintenance to prevent accidents. If you can't find the exact size, visiting a professional shop for tool-measured compatibility testing is the safest approach.
As a daily driver, I've replaced 80/100-18 tires several times and found that they can be interchanged with similar sizes like 80/90-18 or 90/90-18 on 18-inch rims, but with slightly different effects. A small width difference, say from 70 to 85mm, is manageable for everyday road conditions, but a significant change in aspect ratio can make the ride feel harder or softer. Personally, I prefer sticking to the original size, opting for compatible alternatives only when stock is unavailable. Price-wise, the 80/100-18 specification isn't too expensive, costing around 200 yuan per tire, with replacement options available online. Remember, never compromise on safety—always test the stability after each replacement to ensure proper braking. Common alternatives include standard tires from domestic or imported brands. It's best to take photos of the new tire details for future maintenance reference.
