Tires Sailun or Achilles

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 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

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

Sailun, Wanli or GT tried it sa track at highway maganda grip nila \ud83d\ude0a

Sailun ok naman sakin.

Sailun is a cheap Chinese brand but it's damn good in the winter. I think the WS1 or WS2 (studless) is what I had on a rwd car and it handled better than some name brands.

Sailun seems to be decent but my dad had some scary experiences in the rain with a pair of SH408s. IME, they ride decent but felt a little squishy/squirrelly.

Miy Sailun (same tires terr as max) lasted about 30, 000. 4/32 was the measurements before disposal.

My car came with Sailun atrezzo tires—two were new and two were older. I figured I’d just use them until they needed replacing. From the start, they were noisy, and over the course of a year, the noise only got worse. Eventually, they even developed cupping. I just switched to Continental DWS06+ tires, and the difference was night and day. The ride is so much quieter and smoother now.

Just realized Carmax put a new set of these on the 2020 Mustang I bought from them.  Easily the worst performing tire in the rain that I have ever encountered.  Instant hydroplaning on concrete, when there isn't even much of any water.  At least knowing how terribly cheap these tires are, I may not feel bad replacing them before their end of trade life.  Dangerous!  Avoid!
