More Weather Than Weather
For decades, "all-season" has been the standard term both consumers and the tire industry used when referring to a single set of tires meant to serve as a year-round solution. All season tires were marketed as a convenient compromise, offering acceptable performance across dry, wet, and light winter conditions without the need to switch between dedicated summer and winter sets.
Oftentimes, testing (and real world experience for anyone who's actually driven on them) has shown that "all-season" translates to more of a "three season" tire, for multiple reasons; not the least of which is how challenging and slippery winter weather can be to deal with, and the compromises that need to be made to create a product that can deal with it effectively.
Getting into the specifics of research and development is outside the scope of this report, but in short: all tires involve some kind of compromise, because the characteristics that make them good at any one thing means making them worse at something else. Sometimes those differences are slight, sometimes they're major, but the balancing act of creating a tire that's useful all year long is a tricky one.
In recent years, "all-weather" has become the emerging industry standard for drivers seeking true four-season capability. While all-weather tires are essentially just all-season tires that have earned the Three-Peak Mountain Snowflake (3PMSF) symbol (also known as the Alpine symbol), we've found many manufacturers and newer tires making real strides to deliver on the true "all-season/all-weather" promise those words imply.
Enter the UltraWeather - Bridgestone's latest attempt to create a tire that can handle the multitudinous demands of our planet's tilted axis hurtling through space. We'll be comparing it against its predecessor tire - the WeatherPeak - also an alpine symbol-branded tire, and one that has tested well enough in the dry and wet in the past, but clearly indexed more into winter performance at the expense of its warmer weather ability. Has Bridgestone cracked the code with their latest release?
As always: the current tires are all taken out of inventory to ensure they're the same that anyone picking up a set would get from our warehouses. Since we're testing touring tires, we'll be using our favorite commuter car: our 2025 Toyota Camry.
We'll break down our experiences with the tires on our real-world road ride, check out their ability to handle hard turning and braking in both a wet and dry environment, and perhaps most relevantly: discuss ice and snow testing to determine how these two tires deal with harsh winter weather.
The Road
The WeatherPeak has been a fine on-road option in the past, and it was this time as well - it had a soft ride, smoothing over impacts easily, but not a particularly composed one. It was most noticeable over repetitive hits, but there was additional movement, residual up-and-down motion that took away from what was otherwise a nice experience. Noise control was similar: not amazing or overly intrusive, but there was a growl that persisted throughout the ride and across every surface, simmering just below white noise. Not enough to grate, but just enough to notice. The WeatherPeak's steering was one of its brightest points during the road ride, offering decent resistance when turning the wheel, fine return to center, it might not have been the most precise, but it felt appropriate for the Camry.
The UltraWeather distinguished itself from its predecessor almost immediately with the quality of its ride, delivering enough cushion to keep the bumps and undulations from hitting too hard, but also tamping down on any excess motion from those impacts. Noise was functionally equivalent to the WeatherPeak, in that neither tire really rose above "white noise." The steering was an improvement over a tire that we already liked the steering on. The UltraWeather had a solid on-center feel and a progressive build-up of effort; it wasn't overeager, but quick enough to respond that it never felt lacking.
The Winter
There are multiple components to touch on here: the first we'll cover is a snow-covered track run at a dedicated winter testing facility, which allows us to evaluate how each tire actually feels to drive on at speed, during cornering, braking, etc. The next is the objective measurements: how fast does the tire accelerate and brake in the snow and ice?
The WeatherPeak has traditionally been one of the strongest all-weather performers in the snow, really only falling short of dedicated winter products. It still felt good this time around, but was comparatively outclassed by the UltraWeather, which was much closer to the kind of locked down experience we get from a winter tire.
The UltraWeather did a great job on the turn-in, confidently carrying speed, allowing us to controllably rotate the Camry if we wanted to, and find enough traction to power out of corners. It would still slip here and there, but was still a notable improvement over what was already an impressive tire. The WeatherPeak, by contrast wasn't as responsive or precise, the lower limits were palpable, easier to find.
The Numbers
We see this reflected in the objective measurements in the winter for both as well. The UltraWeather hit its acceleration target faster (23.61 feet vs the WeatherPeak at 25.91 feet) and stopped shorter (56.6 vs 58.6 feet). Lap times aren't typically a major concern for non-performance tires, but particularly in a case like this, they're an excellent metric for encapsulating how every aspect of the tire comes together (steering, traction, balance, etc.) to produce greater confidence and control. And in that sense, seeing a nearly 2 second jump from the WeatherPeak to the UltraWeather (56.28 vs 58.04 seconds) represented a marked improvement.
When we compared braking distances for both tires, in both the dry and wet, once again we saw significant performance improvements from the UltraWeather. Dry braking was just over a three foot improvement (93.1 vs 96.6 feet), but wet braking was an additional ten feet shorter (100.6 vs 110.7 feet). Lateral traction in the wet saw a jump as well, with our testers able to achieve 0.80 lateral gs with the UltraWeather tires compared to 0.75 lateral gs on the WeatherPeak. They were tied in the dry for this metric (both reaching 0.86 lateral gs), a fine placement for a touring tire.
