The tire specifications for the Yaris L are divided into 175/65R14 and 185/60R15. The first numbers 175 and 185 represent the tire width in millimeters (175mm and 185mm). The numbers 60 and 65 indicate the aspect ratio of the tire's cross-section (60% and 65%), meaning the height of the cross-section is 60% or 65% of the width. The numbers 14 and 15 represent the rim diameter in inches (14 inches and 15 inches). The letter "R" in the middle stands for radial tire. The Toyota Yaris L uses Bridgestone (ECOPIA) tires, equipped with aluminum alloy rims, and the spare tire is a non-full-size specification. If you want to replace the tires yourself, you can follow these steps: Retrieve the spare tire and jack. Place the jack under the vehicle frame near the tire you intend to replace, ensuring the jack contacts the metal part of the frame. Raise the jack until it supports the car. The jack should be positioned under the vehicle, and you should check to ensure the jack is at a right angle to the ground. Remove the hubcap and loosen the nuts counterclockwise. Do not fully remove the nuts; just loosen them enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn rather than the tire. Turn the nuts counterclockwise until they are loose. Repeat this step for all lug nuts and then remove them completely. Place the new tire on the wheel hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are snug. At this point, the tire replacement is complete. In addition to the model, tires also have the following common markings: Tire cord material: Indicated by Chinese Pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, such as standard rim 5.00F.

The specific tires for the Yaris depend on the model year. My car is a 2022 base model, which comes with Dunlop ENASAVE EC300+ tires in size 185/60 R15. The higher trim versions in our car owner group have 16-inch wheels with a tire width of 195. The recommended tire pressure is around 2.2Bar, as indicated on the label near the trunk threshold. I recently checked my neighbor's 2018 Yaris, which uses Bridgestone tires in size 175/65 R15. It's best to check the label on your door frame for the most accurate information. Avoid changing tire sizes randomly when replacing them, as it might cause issues during annual inspections.

Last time, the car repair shop owner told me that the Yaris tires are quite particular. The mainstream configuration uses 185/60 R15, while some high-end models come with 16-inch rims, changing the size to 195/50 R16. Don't panic when the tire pressure monitoring light comes on; it's most likely due to low tire pressure, and simply adding some air will do. The older Yaris models had slightly smaller tires, about 175 mm in width. Nowadays, it's recommended to use energy-saving and quiet tires with low rolling resistance to save some fuel costs.

Just changed the tires on my wife's Yaris L, original specs were 185/60 R15. During , the mechanic measured with calipers and said the tread should be replaced when worn down to 1.6mm. I took advantage of last year's Double 11 discount to replace all four tires with Continental CC6s - road noise is much quieter now, and they feel softer over speed bumps compared to the OEM tires.

Having driven the third-generation Yaris L, I can confirm the tires have indeed changed. Most models on the road now are post-2015 versions, which come standard with 185/60 R15 tires featuring a 91H load-speed rating. This tire size is quite easy to find, with options like Michelin XM2 and Bridgestone Ecopia EP150 being excellent choices. It's important to note that the original wheel's J-value is 5.5, so avoid blindly upgrading to 195-width tires. Regular tire rotation can help extend their service life.

Last week, I helped my younger brother choose new tires and noticed that the Yaris specifications are quite standardized. There are mainly three sizes: the base model comes with 175/65 R15, mid to high trims with 185/60 R15, and the top trim with 195/50 R16. Prices for 15-inch tires are reasonable within the 300-500 range. It's advisable to stick with the manufacturer-recommended sizes, as arbitrarily upsizing may cause rubbing against the wheel arches. For tire pressure, I usually inflate to 2.3 Bar when the tires are cold. The tire pressure warning light came on twice during sudden temperature drops, but adding a bit of air fixed it.
