The new Bridgestone WeatherPeak is Bridgestones first attempt at an all weather tire for the North American market, and if the initial data is correct, it could be the first tire to knock the dominant Michelin CrossClimate 2 from its top spot!
All weather tires are developed to be better in winter conditions than traditional North American all season tires, which some are now referring to as three season tires due to their limited snow performance. All weather tires aim to be a true "one tire for all conditions", and while no perfect tire exists yet, modern technology means these jack of all trades are getting better.
As we have yet to drive on the new WeatherPeak there is limited data we can say provide, however the following data stood out from the press release:
- 5% better wet acceleration than top competitor 
- 4% better dry acceleration than top competitor 
- Stops 14 feet shorter in the snow than all-weather competitor 
- Stops 30 feet shorter in the snow than all-season competitor 
Who are the competitors referenced in notes  and ?
 Comparison based on Bridgestone WeatherPeak tires vs. MICHELIN® CrossClimate® 2 tires from internal testing. Results may vary depending on proper tire and vehicle maintenance, road conditions and driving habits.
 Comparison based on Bridgestone WeatherPeak tires vs. MICHELIN® Primacy Tour A/S tires from internal testing. Results may vary depending on proper tire and vehicle maintenance, road conditions and driving habits.
"Internal testing" should always be viewed with caution, but to be 5% better in the wet, 4% better in dry, and have a far shorter stopping distance in the snow than the CrossClimate 2... that's impressive!
Other key points - Every size of the WeatherPeak is three peak mountain snowflake symbol (3PMS) marked, the WeatherPeak has a 70,000 mile limited warranty, and the tire will be available in 56 sizes which Bridgestone claim will fit 87% of sedans, SUVs, and crossovers on the market.
Naturally Tire Reviews will try and get these included in a test as soon as possible. The move to all weather tires in North America is slowly gaining momentum, and is a welcome change for many parts which see heavy winter conditions.
