What is the tire specification for the Regal?
2 Answers
The 2.0L and 1.6T versions of the Regal are equipped with 225/55R17 tires front and rear, while the 2.4T version and the 2.0T flagship model use 245/45R18 tires. Here are some additional details: 1. The wheel rims are a highlight of this model, specifically designed as sporty rims for the 2.0T flagship sports version. 2. The five-claw design is very dynamic, featuring lightweight construction and excellent heat dissipation. 3. The tires are still the Bridgestone EL400 model, which is primarily designed for comfort. During testing, these tires exhibited frequent squealing, but their specifications are quite high, reaching 245/45R18, which is more generous compared to other vehicles in the same class. Additionally, the braking system uses front and rear ventilated discs to ensure outstanding braking performance. 4. The Regal's ECOTEC 2.0L all-aluminum engine features cylinder heads and blocks made of aluminum alloy, utilizing advanced semi-permanent mold casting technology for durability and strength.
I've been driving a Buick Regal for several years, and the tire specification is usually 225/55R17. This size is the factory standard, with a width of 225mm, an aspect ratio of 55, and a 17-inch rim. The ride is quite smooth, offering both comfort and a sense of control, especially with strong grip during high-speed turns. It's best not to casually change the tire size when replacing them, as it may affect the speedometer and fuel consumption. I also regularly check the tire pressure, keeping it at 32-35 psi—too high can make the ride bumpy, and too low increases wear. Tires typically need replacement every 5 years or so, as severe wear can extend braking distance, which is unsafe. When washing the car, I also check the tire tread depth—it saves money and gives peace of mind.
