Good grip all arround, especially in the dry where they really shine. Used them as front tires on high power rwd car. They maintain good grip under heavy braking, and are very progressive at the limit. The only downside i found is that the got oval shaped and the car started vibrating at high speeds, wich cannot be resolved by balancing since they were not perfectly round.aybe the car being rarely used, it sits in the garage over winter, and only moved around a bit every few weeks, but maybe that was not enough, even though the rear ones, a different brand did not suffer the same problems.

What drivers say about their 305/35 R20 tires
The most recent owner reviews fitted in this size, in their own words.
I only run them on my mustang as A run around the work well would use them anytime very impressed with them .
They are completely useless. At temperatures below 25 degrees Celsius, you already have a flat spot after just 1 day of standing, which only slowly goes away after 30 km at more than 160 km/h. Absolute cheap Chinese junk for an outrageous 400 euros each. Presumably, no developer has ever tested the tires in real conditions. Pirelli is out of the question for me again!
Hi, From a start position tires felt like they were to hard and did not grip as well leading to spins just in normal everyday traffic. The car would hydro plane in puddles on the highway, to the point I had to reduce speed and remove myself from the highway. The feed back from the tires was average. In corners on sunny days the tires were very responsive and felt secure. These tires had a tire wear rating of 500 but only lasted 17398 miles to a tire depth of 3/32 in a mix of city and highway driving applications. The tires were reasonably comfortable in the city or on the highway. Tires last me typically 4 years or 50,000 mile before a need to buy a new set , these tires lasted a little over a year therefore I would not purchase them again. I may choose Good Year Eagle all seasons due to expected value per mile ( tread wear / price) and professional reviews such as Tire reviews.
Bought new Pirelli P Zero tires. During balancing, it was already apparent that there was severe radial and lateral runout. The mechanic attempted to improve the result by "matching" the tires, but unfortunately, to no avail. Strong vibrations occur when driving at speeds above 75 km/h (47 mph), which don't subside even at speeds above 200 km/h (124 mph).
The tires are absolute junk, even over two years old. Probably a defective product or a warehouse error, entirely at the customer's expense. My rims are new, as they were a new car. The old tires only had one flat, so I got new ones.
Pirelli is unwilling to accommodate. The sales representative is unable to provide clarification.
Evidence is being secured + a lawyer is being hired.

Use these tires as my run around and put my r888r on for summer they are a good value tire fills the gap perfect
Used them tp replace the all seasons on the front axle, driven fpr around 3.000km, they grip very good on dry tarmac, i did not drive in the wet except when the roads were a bit damp, but they were confident enought, and did not get any surprises.
They do very well on heavy braking, and are comfortable enought. So far no wear on them but not really driven that much. I drive the car on street , in a spirited manner. Sp far very happy with them, once the Pzero allseasons on the other axle will wear, i will also use Pzero pz4 as i am satisfied woth them.

I purchased 2 sets of these tires the 1st set managed to get about 16k miles and the 2nd set last about 4 months and 10k miles. I called perelli to see if they could help out with warranty and got told no. These tires is horrible and I will never buy another set of Pirellis ever!!!! If your looking for a good tire look elsewhere other than Pirelli
