i did a lot of research including tirerack.com for review of this specific tire. i wanted a tire that can haul through snows,ice,wet,n dry without the use of specific season tires. so i opted for the pirelli p4 all season. the pirelli had excellent review based on consumer results. before i ran with kumho solus kr21. The Kumho solus performed excellent on dry and overall a good tire but LACK the traction on ice and snow roads. As the tread wears out on the kumho the noise levels were becoming more apparent and the treadwear only met 40k miles before needing to replace. Cornering were wobbly with the kumhos and must be used with cautions. Overall the Kumho could use some improvement on cornering and snow,ice traction. Immediately after i switch to the Pirelli i felt how quiet the tire is and the comfortable ride it absorbs through bumps. i can now hear my passenger and music on the highway without them raising their voice. i ran the tire through our first minnesota winter and i had to say these felt like the actual winter tires. really no kidding i can actually felt the dig of the tire through the 4 inch deep snow to the pavement. Ive tried stepping brakes firmly on snow covered roads and i was surprised my ABS hardly kick in. Cornering is a lot more stable and steering is very responsive compare to the Kumho. On slush and ice pack road the tire cuts through it without hydroplaning. Overall i rate this tire a 9/10. Possibly the best all season tire ive had n its ranked 1st for my tire size. The only negative i had to say about this tire is that i felt the car is somewhat slower than before but b/c of the excellent traction in return it's well worth the money. Overall the tire is solid handles snows predictably excellent and cornering is more precise and very comfortable tire and very low noise level. I recommend and will buy this tire again.
