Bridgestone Ecopia EP422 Plus vs Kumho Solus TA51a tires on traction

When shopping for tires, it's important to consider traction. Traction is what keeps your tires surefooted to the road, ensuring you stay in control behind the wheel. This factor plays a pivotal role in driving safety, impacting how quickly you can brake, how well your tires resist hydroplaning, and your overall ability to maneuver. The traction of a tire depends on various factors, including its tread design, pattern, and the type of rubber used, all working together to enhance its performance.

In traction, the Bridgestone Ecopia EP422 Plus offers a great score of 8.7 thanks to the wide grooves within the tread that remove water from the tread for added hydroplaning resistance and confident grip in wet, dry, or light winter weather conditions.

The Kumho Solus TA51a scored a great score of 8.6 in traction thanks to the four wide linear grooves that improve hydroplaning resistance by improving water drainage.

With a slightly better SimpleScore, the Bridgestone Ecopia EP422 Plus takes the win here. However, you can be assured that both tires will deliver solid traction in dry, wet, and light winter conditions.

Bridgestone Ecopia EP422 Plus vs Kumho Solus TA51a tires on handling

When selecting tires, it's essential to focus on handling, as it greatly impacts your ability to control the vehicle, especially at higher speeds. Optimal handling allows for smooth maneuvering, and effortless lane changes, and overall enhances your driving pleasure. This vital aspect is affected by various factors, including tread design, the type of rubber used, and the incorporation of cutting-edge technology in tire manufacturing.

The Bridgestone Ecopia EP422 Plus scored a great score of 8.8 in handling thanks to the symmetrical tread pattern and sidewall design which provides smooth cornering performance and lane-switching maneuverability.

In handling, the Kumho Solus TA51a received a great score of 8.5 thanks to the high silica chamfer block edge that bites into the road, which in turn improves handling.

Bridgestone Ecopia EP422 Plus vs Kumho Solus TA51a tires on longevity

Longevity is of paramount importance to drivers when selecting tires, as it directly impacts the mileage they can attain on a single set. As the tread gradually diminishes over time, the significance of tires offering prolonged longevity becomes evident, ensuring consistent handling and traction over an extended period. Factors such as tread design, rubber composition, and tire construction together influence the tire's lifespan.

In longevity, the Bridgestone Ecopia EP422 Plus scored an excellent score of 9.4 which is paired with a 70,000-mile limited manufacturer tread life warranty. The tires are designed to deliver an optimized footprint, which in turn allows for even tread wear for a longer tread life. Additionally, the low rolling resistance of the tire improves fuel efficiency.

The Kumho Solus TA51a received an excellent score of 9.3 in longevity thanks to a unique tread design that resists uneven tread wear, which is also aided by high silica chamfer block edges. Additionally, the tire has a low rolling resistance design that reduces fuel consumption without compromising on performance. The Kumho Solus TA51a is also backed by an up to 75,000 miles limited manufacturer tread life warranty.

While both tires go toe to toe in longevity with excellent scores, the Bridgestone Ecopia EP422 Plus takes the win again. However, interestingly, the Kumho Solus TA51a has a slightly better mileage warranty of 75,000 vs 70,000 miles.
