When it comes to all-season tires, Bridgestone and Yokohama are pretty much at the top of the game. Both manufacturers have been around for decades and have been first-to-market with several tire innovations. Both have extensive experience in the motorsports world that informs their designs. Both have many tires featured as OEM from the factory on many high-end vehicles.
All-season tires are the biggest-selling category since they’re a good jack-of-all-trades solution for most drivers. With that in mind, the Potenza Sport A/S from Bridgestone and the Yokohama Advan Sport EV A/S are good examples of what a modern performance-oriented all-season tire design is all about.
While these tires are similar in design and performance, they also have some key differences. In the course of this head-to-head comparison, you’ll see us make frequent reference to the SimpleScore numbers of these two tires. If you’re unfamiliar with it, SimpleScore is the proprietary ranking system the SimpleTire team has developed. We look at specs, reviews, and other data points and distill that into a numerical score for traction, handling, longevity, and an average SimpleScore number. For the Bridgestone and the Yokohama, the SimpleScore ratings break down thus:
Those SimpleScore numbers are certainly handy for giving you a quick overview of a tire’s performance and value, but it’s also a 30,000-foot view that doesn’t tell the whole story. To understand the details, let’s look at this product comparison.
The Bridgestone Potenza family of tires has been around for a while, and the Potenza Sport A/S is one of the latest iterations. This performance-oriented all-season tire is designed to give you UHP levels of steering response, cornering ability, and braking for pulse-pounding excitement when you want it, along with dependable year-round traction and versatility for daily driver duties.
The Potenza Sport A/S is designed around Bridgestone’s PeakLife polymer-blend tread formulation, engineered for long, even wear properties and excellent traction on wet or dry pavement. Handling and cornering are top-flight thanks to large shoulder blocks reinforced to resist tread squirm and deformation during hard maneuvers and a solid center rib that gives the Potenza Sport A/S dead-solid stability and sharp steering response. Bridgestone covers the Potenza Sport A/S with a 50,000 mile manufacturer’s tread life warranty.
Year-round all-season traction comes from circumferential and lateral grooves that help resist hydroplaning by forcing water out of the tire’s contact patch for better wet-weather grip. A dense network of full-depth 3D sipes multiplies the tire’s surface area and traction with hundreds of extra biting edges that slice through snow, slush, and standing water. The internal construction of the Potena Sport A/S includes a polyester carcass with a high-turnup sidewall reinforced by two steel belts and a spiral-wound nylon cap layer for great stability on the highway. The tread pitch and shoulder slots of the Potenza Sport A/S are randomized and computer-tuned to help keep road noise minimal. SimpleTire’s list price on the Potenza Sport A/S starts at $179.99/tire.
The Yokohama Advan Sport EV A/S is an all-season tire with a twist – it’s optimized for use on electric vehicles and hybrids. EVs and hybrids have unique requirements for tires; any tire they use needs to be designed for the extra weight and lower center of gravity of an EV’s battery pack. They also need minimal rolling resistance to get the most range out of an EV’s charge, and they need to be whisper-quiet on the highway since EVs have no engine or exhaust note, and tire noise would be extra noticeable.
The Advan Sport EV A/S contact patch has been refined and optimized for more road contact and improved weight distribution, which is especially important considering the power and torque of EV drive trains. The Advan Sport EV A/S is also designed with a new all-season silica-enhanced tread compound that keeps rolling resistance low while delivering top-notch grip and long wear (long enough for a 55,000 mile manufacturer’s treadwear warranty).
The Advan Sport EV A/S's enhanced sidewall and shoulder blocks enhance its load rating and give this tire the rigidity it needs for outstanding cornering ability and steering response. Its design of circumferential grooves, Z-grooves, angled grooves, and wavy sipes boosts all-season traction, which all work together to provide excellent traction on wet or dry pavement. Starting at $230.99/tire, the Yokohama Advan Sport EV A/S gives EV drivers a great balance of performance, versatility, comfort, and long, durable wear.
The traction category is not close, with a SimpleScore of 9.3 for the Bridgestone and 8.4 for the Yokohama. Why the big disparity in SimpleScore ratings? Testing shows that the Bridgestone delivers shorter braking distances on wet or dry pavement and performs better in snowy conditions than the Yokohama. Reviews tend to back up those observations. While it’s an all-season tire, the Bridgestone can check the boxes you’d expect from a UHP tire, which includes in the traction category. Our call:
ADVANTAGE: Bridgestone Potenza Sport A/S
Regarding handling, the Bridgestone Potenza Sport A/S and Yokohama Advan Sport EV A/S aren’t closely matched, with a SimpleScore of 9.3 for the Bridgestone and 8.7 for the Yokohama. The Potenza tire line has been around since 1979, and Bridgestone continues to develop and improve these tires. These full-depth 3D sipes give the Potenza Sport A/S a boost in year-round traction and enhance the rigidity across its tread face to resist tread squirm and deformation during hard maneuvers. That keeps the tire firmly planted on the pavement with glue-like traction, and the stiffer shoulder blocks and high-turnup sidewall resist the inertia and momentum that goes along with plowing into a corner at high speed or carving up an onramp. Our decision:
ADVANTAGE: Bridgestone Potenza Sport A/S
Now, we come to another mismatch of SimpleScore ratings, except in the other direction. The Yokohama comes in with a SimpleScore of 9.3 for longevity vs 8.8 for the Bridgestone. The Yokohama has a 55,000 mile manufacturer’s treadwear warranty vs 50,000 miles for the Bridgestone, but that doesn’t tell the whole story. The reinforced structure of the Yokohama helps it handle the extra weight and different driving dynamics of EVs and hybrids but also gives it an edge when it comes to service life, along with that specialized tread formulation. Our call:
ADVANTAGE: Yokohama Advan Sport EV A/S
While the Bridgestone Potenza Sport A/S and Yokohama Advan Sport EV A/S are performance-oriented all-season tires with many in common design, they also have some distinct differences. The biggest difference is that the Advan Sport EV A/S is a tire custom-designed around the requirements and driving dynamics of today’s EVs and hybrids. That includes the weight, torque, power, handling, and altered center of gravity that goes with an EV while still delivering the kind of performance and wear properties that drivers have come to expect with Yokohama tires. If you drive an EV, the Yokohama would be better than the Bridgestone Potenza Sport A/S; conventional all-season tires might work for an EV but would likely not meet tread wear and handling expectations. The Bridgestone would be a great choice for a non-EV conventional vehicle, with a forgiving ride, low noise, sharp handling, and long treadwear.
This is a question that comes down to what you’re driving and what your needs are. If you’re driving an EV or a hybrid, we’d have to recommend the Yokohama Advan Sport EV A/S hands-down. That said, the Yokohama and the Bridgestone are both suitable for a conventional internal combustion vehicle (but the Bridgestone isn’t suitable for an EV). If you’re driving an ICE vehicle, choose between the Bridgestone and the Yokohama. In that case, we’d recommend the Bridgestone since that’s a tire that ranks better in terms of SimpleScore ratings.
