Old vs. new tire tech

This demonstrates all the reasons to avoid cheapo tires.

As a tire engineer, I'll bet this is all about rubber chemistry. I've worked alongside some very talented chemists who have done some amazing things.

Which tire brands do you perceive as having the highest quality, and are there any that you would say to steer clear of?

One thing I notice is that more and more, new tires have a B traction rating, and an A temperature rating. I was just next to a Mazda CX-90 this AM and admiring the 275's, which is wide for a Japanese vehicle. Then I saw the B traction rating (factory tires).

Personally, I would prefer AA A, but these are self reported so take them with a grain of salt. It's like asking a man his height and his salary. Good luck getting a truthful answer.

I read a response from Michelin regarding the B traction rating, the test is very out of date in their opinion.
