What is the tire model of the Highlander?
4 Answers
The tire model of the Highlander is 235/55R20. The first number 235 represents the tire width of 235MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 20 stands for the rim diameter of 20 inches. The middle letters or symbols have special meanings: "X" denotes high-pressure tires; "R" and "Z" indicate radial tires; "—" represents low-pressure tires. The Highlander has a maximum speed of 180km/h and a fuel consumption of 5.8L per 100km. In addition to the model, the tires also display the following common data: 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 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, such as "Standard Rim 5.00F".
I've been driving a Highlander for several years. The tire sizes are usually 245/60R18 or 245/55R19, depending on the year and configuration. For example, mine is a 2020 model with factory 18-inch wheels. This size provides good stability on highways and excellent grip on wet roads, but tire pressure needs regular checks due to the vehicle's weight causing faster wear. Last time, I switched to a third-party brand, Michelin, which saved money and was more durable. I recommend checking tire pressure every six months, maintaining 32-35 psi, and checking tread depth before long trips. Don’t randomly change sizes as it affects suspension and fuel consumption. When choosing tires, it's more reliable to go to a professional shop.
Tires are crucial for driving safety. The common tire size for the Highlander is 245/55R19. As an owner, I always check tire pressure before long trips, maintaining around 35 psi. Wrong sizes can cause severe wobbling and make the car prone to skidding on wet roads. Also check the manufacturing date to avoid aged tires. When replacing tires, prioritize OEM-matched options like Bridgestone or Goodyear - don't underestimate this, as poor grip increases braking distance, especially when fully loaded. Regularly wash your car to remove debris from treads, extending tire life while improving safety.
I use the Highlander to pick up and drop off my kids, and the original tires are mostly 245/60R18. The large size provides ample space, but low tire pressure can cause bumps, affecting the children's comfort. I check it myself once a month and use a tire pressure gauge to adjust it to 34 psi. A small tip for model changes: after running a tank of fuel with new tires for break-in, then take them on the highway. For family use, don’t skimp on this expense—safety comes first.
