Another feature that contributes to a tire's water handling capabilities is compounding. Silica is a common additive to tires to increase their grip levels in water. Silica infused rubber also resists getting firm in the last half of a tire's life. Hydroplaning is one of the last things we want to experience as drivers and to better understand how your tires affect your ability to drive in wet conditions, read "Hydroplaning: The Roles Tires Play."
Each time a tire is brought up to its operating temperature by driving is known as heat cycling. A heat cycle is completed when the vehicle has been parked after driving and the tires return back to a cooler temperature. As a tire ages and the amount of heat cycles increase, often times the rubber becomes firmer and less compliant as a result. Silica infused rubber resists the firming tendency due to heat cycling.
Below are a few of the all-season tires that have good wet handling capabilities:

We tested each tire on our closed track that was watered heavily by sprinklers to simulate standing water. All of our sales specialists tested the aforementioned tires by driving one of four identical BMW 3 Series test vehicles. To see how we test the tires that we recommend, check out "Tire Rack's Tire Testing Program."
And, if you're looking for all-season tire reviews, take a look at the Tire Test Results to see how each tire performed, then shop by vehicle to find the tire that works best for your vehicle.
