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 tyres
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!
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.
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.
