Michelin Pilot Sport 4 vs Pirelli P Zero Corsa — Compared

“I ran the stock 17" Ecopia's on my Ecosport for about 45k km. Luckily didn't face any side wall cuts. Overall it was a average tyre with decent grip levels - good grip without any squealing when driving up a ghat road quite enthusiastically even at the fag end of it's life. Ride quality was pretty bad and the smallest of ruts would result in a thud and being low profile amplified it even more. The tyres developed these cracks along the shoulder around the 35-40k mark which should not have happened due to which I changed them at 45k even though there was probably enough thread for about 5-10k km more. Moved to the Michelin PS4 now and the difference is night and day!”

Overall Pirelli Cinturato P7 are the longest wearing tires I've owned over the years at 20k miles consistently. I swap out run flat tires if they come on a new car. I believe that heat is a major cause of tire wear. Even after a 2 mile trip @ 35 mph the tires on my E300 register about 120°F. Cold they are between 80°F and 85°F. In the dead of winter they are 5° colder. The OEM tires on my 5 year old '18 E300 got 12k miles. The car has 20k miles on it now and the P7 tires are about 40% worn. My experience with Summer tires is 15 to 18k max. The only Summer tires that I have owned that lasted more than 20 were the Pilot Sport PS4...which BTW is one of their marketing highlights, longer tread wear...though still shorter than all seasons which normally are rated for 30k or more.”

“The Pilot Sport 4's are great tires for dual duty use. You'll want to keep hot pressures below 37-38 PSI. Anything above that they get very greasy, very fast. In the cars I've driven with them (a few BMW M cars, a 911 I think if I remember), you'll usually set your best laps in the first 4-5 laps of a session depending on temps. Once they over heat heat, as with any street tire, you have to park them for an hour to get the temps down again (downside to steel radials). I'd also recommend Hankook RS4s if you want a more durable track tire. That's what I run. Very long lasting, but not as great in the wet as the PS4s would be. Road noise would also be an issue for street use.”
