The original tire models for the Lexus UX are 215/60R17 and 225/50R18. The functions of the tires are: 1. To transmit driving force, braking force, and steering force for vehicle operation; 2. To support the vehicle load; 3. To reduce and absorb vibrations and impact forces during driving, preventing severe vibrations from damaging vehicle components. Taking the 2020 Lexus UX as an example, its body dimensions are: length 4495mm, width 1840mm, height 1540mm, with a wheelbase of 2640mm. The 2020 Lexus UX features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 173PS, a maximum torque of 207Nm, and a maximum power output of 127kW.

As a car enthusiast who has driven the Lexus UX, the original tires are typically sized 225/50 R18, such as the Bridgestone Dueler H/P Sport AS or Michelin Primacy. The 225 indicates a tire width of 225 millimeters, 50 is the aspect ratio accounting for 50% of the tire width, and 18 refers to the 18-inch wheel size. This design suits the balanced performance of compact SUVs, combining shock absorption and fuel efficiency. In actual driving, I found these tires to be quiet with excellent grip, especially stable during high-speed cornering. However, specific models may vary by trim level and production year—for example, higher trims might use Michelin. To maintain tire condition long-term, I recommend checking tire pressure and wear every 10,000 kilometers, cleaning them regularly to prevent debris from embedding in the treads, which can extend their lifespan to at least 50,000 kilometers.

I pay special attention to automotive safety. The Lexus UX typically comes with original tires in the size 225/50 R18, often from brands like Bridgestone or Michelin. This configuration performs exceptionally well on wet surfaces, effectively reducing braking distance and minimizing the risk of skidding, thereby enhancing driving protection. Having driven on mountain roads several times, I've noticed that the tread pattern design of these tires allows for quick water drainage, preventing hydroplaning. However, if your daily routes have many potholes or encounter snow and ice, it's advisable to promptly switch to high-quality replacement tires to improve anti-slip performance.

Briefly speaking, the UX comes with factory tires usually sized at 225/50 R18. Many owners, including myself, commonly encounter the Bridgestone Dueler series. Other alternatives include the Michelin Primacy, which are known for their durability and quietness, making them ideal for daily commuting.
