Dunlop. The tire brands used by include: ES350: Bridgestone; GS300: Dunlop; GS430: Dunlop; IS300: Bridgestone; RX350: Michelin; RX400H: Michelin; LS460: Bridgestone; LX470: Dunlop. Tires are one of the most important components of a car, and their main functions are: 1. To support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; 2. To transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the car's power performance, braking performance, and passability; to work together with the car suspension to mitigate the impact during driving and dampen the resulting vibrations; 3. To prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and energy-saving economy.

I remember when driving my RX300, the original tires were from the Bridgestone brand, probably from the Dueler series, which felt stable and wear-resistant. However, not all cars are the same; some versions use Michelin or Dunlop tires. I recommend checking the side of your car's tires, where the brand name and model are printed. If you frequently drive long distances, remember to check the tire pressure and tread depth monthly to avoid excessive wear affecting safety. When replacing, you don’t necessarily need the original brand; just choose tires with similar performance. Tire selection is quite important, as good brands can enhance handling and comfort, making driving more reassuring.

As someone who has worked in garages for a long time, I've encountered many RX300 owners inquiring about tire issues. The original tires are usually premium brands like Bridgestone or Michelin, depending on the production year and configuration. You can visually inspect the sidewall markings to confirm the brand. Just a reminder, tire performance affects braking distance and stability, so regular is crucial. If the brand is unclear, consider measuring the tread depth; if it's below 3mm, replacement is recommended. Replacement options include reliable brands like Yokohama or Goodyear, ensuring compatibility with the vehicle model.

As a car enthusiast who has studied the details of the RX300, its tires may originally come from big brands like Bridgestone or Dunlop, but don't blindly trust online rumors—checking the actual tire label is the most accurate. The tire brand affects noise and fuel consumption, with high-end series performing better on slippery roads. If you're replacing tires, choosing one with strong grip is sufficient; there's no need to go for the most expensive option. Regularly washing your car and checking tire pressure can help extend their lifespan.

From a safety perspective, as someone who has driven for years and pays close attention to tires, the RX300's original tires are often Bridgestone or Michelin due to their excellent grip. I strongly advise you to immediately check the tire markings to confirm the brand. Regular like checking air pressure and wear can prevent blowouts, especially during rainy weather. When replacing, choose safety-certified brands like Continental or Pirelli, ensuring the tread pattern matches your vehicle model. Never overlook minor damages—address them promptly to ensure safe family travels.

I'm usually very careful with my budget. The original tire brand for the RX300, like Bridgestone, might be more expensive, but there are cost-effective options like Hankook or Nexen when replacing them. I suggest you first check the brand name printed on the tire sidewall to confirm the original, then compare prices. Tires typically last about 5 years, so regularly check the pressure to avoid uneven wear. When new ones, choose tires with similar performance—you don’t need to buy expensive original ones, which can save you a lot of money. The key is to ensure the tires are reliable; being economical doesn’t compromise safety.
