2003 350z replacement tires - previous tires Michelin! Spend another 200 dollars and go Michelin!! These tires are noisy - can't stay balance

I have 22k miles on these tires. Almost all highway. 2 months ago I had a blowout on the highway. Very scary. Took the car in to Big O where I purchased. Tire definitely defective. So I paid my 100 to replace the defective tire. This morning I took the car in because the same issue was about to happen. Paid 100 to replace another defective tire.
Why do I have to pay to replace something under warranty at all... Even proration does not seem right. Tires are the main safety feature of a car. This makes no sense. I guess I am lucky I wasn't hurt when my front tire blew at 70mph.
This morning I have read multiple reviews showing that this is not just a fluke. Multiple reports of low mileage blow outs.
(Somewhere between 19k and 23k miles). Multiple accounts of more than 1 tire of 4 purchased going out. I would never recommend this brand and in fact I may never buy from the dealer again though I have been a patron for almost 2 decades. Worthless warranty. When the tire is defective and happens more than one time... Safety is of no consequence to this manufacturer. Guess it will take someone being seriously injured or dying before they take it seriously.
DON'T BUY THESE TIRES THEY ARE DANGEROUS.

Great, quite ride...I live in New England and there tires handle the snow and rain as well as any tires I've owned. Very quiet and smooth ride.

Bought 4 Sumitomo Tour Plus LST tires on Aug 10, 219. On Aug. 15, 2019, Tire dealer had to replace bot back tires due to belt defects.
The 2 new tires, were no better.
The belts, felt like they were separating on these as well. Tires, were, loud, hard, bumpy, vibrating badly from day 1. Didn’t want any blowouts on the highway, so dealer had to change out all tires, for Hankook Kinergy PT H 737....
Happy as a clam now!!!... HUGE difference. I was told, at one of my trips to the dealer, that Sumitomo changed their rubber composition, and they’ve had nothing but problems since.....Steer clear of these tires!...You’ve been warned!..

so far so good, better than my Continental Contacts which lasted less than 25k

Worst tires ever. EVER. They were realigned every time I got my oil changed and yet my car shook constantly...and shook hard -- so hard my face skin was shaking. Miserable wastes of money. Save yourself some money and angst -- your car is meant to be enjoyed.

I got these tires at Tire Kingdom. They were highly recommended by the employees. DO NOT get these pieces of trash. They vibrate like crazy. They've been rebalanced and still vibrate. The steering wheel just shakes like hell.

They have exactly ZERO wet traction. I found that out by almost wiping out my car by trying to take a turn at 15mph. Wet traction is so bad I can spin the tires profusely in 4th gear at 65mph just punching the gas... If I'm not careful the back end just steps out in the rain. It loves to do this if you come over a hill and the hill crests into a turn. Instant sideways, which is always fun when you don't expect it. The bald General Exlaim UHP these replaced gripped far better.
