Tires Pirelli or Sailun

They were both originally Sailun Inspire 215/55R17 touring all-season. They replace with with a Sailun Inspire 215/55R17 XL. The XL has a different load weight and a different PSI. From my research online, this could be caused by the tire speeds not being the same and the tires being mismatched. Does this seem possible to you? I could call the tire place and ask if they'd honor a replacement because they put a non-matching, non-compatible tire on the car... It's essentially new as I've only driven maybe 500 miles max on that tire.

I like Pirelli ice zero fr, they have the best grip, Bridgestone also fine

I have a car that only gets used 3x a month at the most. Sailun Atrezzo Elite! Took it to La Union during a heavy downpour and it was also fine. Came from Arivos but the sidewall is too soft imo

Pirelli WeatherActive

Today I will get Pirelli runflat because sounds like it has better thread wear than continental .

Sailun is great brand, I use it a lot. Definately recommend.

I have pirellis on a range rover sport. Got 30,000 miles out of them. Expensive tire. Wondering if different brand will do the trick

I just had these put on my ‘23 R1S. The ride home was smooth. I didn’t notice any difference between the stock Pirelli’s as far as noise and quality go.

My only experience with Pirellis was a set of P6 All Seasons that I put on my old Acura TL fifteen years ago. It transformed my ostensibly “luxury car” into one that rode like a cement truck.

I bought a set for my daughter's car and she had a sidewall blowout driving down the interstate. Thankfully she didn't crash. We took the tire back to the Meineke were purchased, who then sent the tire to Sailun. They said the tire would not be covered under warranty, even though it was only 3 months old.
