“Pirelli cinturato P7 and Pirelli Powergy Hi all 👋🏼 So I had 4 Pirelli Cinturato P7’s on my Ford Focus ST. I got a flat tire (front left) while I was on vacation so I decided to get 2 new tires at the front. I asked the guy at the tire shop to get the same tires (so the Pirelli Cinturato’s). He got me Pirelli Powergy’s instead… He didn’t really speak English and there was not time as I was driving home the next day. So I just accepted it. Now my question is what’s the main difference between these tires? And does it matter I got 2 different tires now? (2 powergy’s at the front and 2 Cinturato’s at the back) Thanks!🙏🏼”

Firestone TZ300
We haven't collected enough community discussion about this tire yet.
Tire B
Mixed
Pirelli Powergy
Community opinion on the Pirelli Powergy is largely mixed, with the tire frequently viewed as an eco/budget, mid-tier option suitable for daily driving rather than high-performance use. While some users consider it a cost-effective, fuel-efficient choice from a reputable brand, others report negative experiences including excessive highway vibrations and potential sidewall defects. A significant number of discussions also revolve around general inquiries regarding safety, longevity, and whether it can be mixed with other Pirelli models.

“Avg 29mpg on a 2015 Mazda 3 Sport Nav 2L 165bhp, any ideas? I've had this car for about 3-4 weeks now, posted it here on this subreddit too. So far, I've done about 800 miles and my average fuel consumtion seems to be around 29mpg - 10.2L/100km. The car doesn't have its original rims, its on **MAM RS3** 18" rims with Pirelli Powergy tires 215/45/R18 (internet says these tires provide good fuel economy). On longer trips the average is about 40mpg-45mpg which still seems a bit high. My work commute is about 2 miles, and I do occasionally drive in a spirited manner. Is this okay? Thank you all!”

“Ripples in side wall Just been washing the car and found what I can only describe as ripples in the side wall of my front-right tyre. Had these fitted in June, only just noticed the ripples. The other tyres are perfect. I’ve probably done around 2,000 miles on them. Should I be concerned, and do they look like a manufacturing defect, or as a result of damage? (I’ve not hit any serious potholes that I’m aware of). These tyres are Pirelli Powergy, fitted to a Volvo XC60. Date code is 3325. Any help gratefully received. Read more”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
