This video is fantastic - I really like the Engineering Explained guy and I think this test is fascinating. It's like Harry Hogge says to Cole Trickle in Days of Thunder "Tires....tires is what wins races." Enjoy. Glad I run the Conti Extreme Contact Sport 02s!
Old vs. new tire tech
- Thread starter TiGeo

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.
I have never understood why E.E. is not more popular, especially when the masses fall for useless Scotty-like clickbait so often. E.E. is down to earth TECH that is understandable for the average Joe. The guy is a bit nerdy but has excellent content. Top notch!
While it sounds almost like an ad at some points.. I feel its presented well.
and its shocking how much better those are vs the DW which were good at the time of release.

Excellent test!
When video shows the difference in stopping distance, it is what it is telling to me.
Some 20yrs ago, I was driving and some kid ran out on a bike on to the street, that is more of a hwy. I slammed the brakes, pushed the horn, etc., and I managed to steer the car in such a way as to hit him in the rear tire, throwing him onto some pile of sand. He had some scratches, but other than that he was fine.
However, I needed probably a year to psychologically recover from that. I stopped probably car length after hitting him.
So, when people argue that all tires are the same and that name brand does not matter, they have no idea what they are talking about.

Why? According to a new study, 20% of the American population is technically illiterate.
His explanations are too technical for most people. Not his fault!
This one is easier to understand. But first thing I thought when he said "simple math," were those 20%.
One thing here is that these are summer tires and the compound used for them will not perform as well in cooler temperatures. The warranty will be voided if they are loaded or deformed in temperatures below 20 F. The compound will crack in lower temperatures.
What someone would want to do is unmount them as soon as the temperatures cool off and store them in a climate controlled area.
As with a lot of things when purchasing tires we have to make compromises for all driving conditions that we may encounter, so that means for most of us is that we are going to choose tires that are in the All Season category that are made with compounds that are going to behave acceptably under all conditions we will anticipate.
Great video but I would like to know the ambient temperatures and how each tire would perform at lower temperatures such as around 50F.

Why? These are summer performance and as such, being used as intended and the testing was done in the correct conditions. There are plenty of videos on YT that put summer vs. all seasons in colder temps, check out tyrereviews channel, I've posted links here numerous times. I guess I'm not sure what the point of this post is? It's kind of a "duh"? I just removed my summer tires (same ones...Conti ECS02s) this morning, I have them on separate wheels as would most folks runnign tires like this, they stay in my garage which will not go below 50 F in the winter here in VA.

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.

That was a great vid, thanks for posting. I added the channel to my subscriptions.
I prefer traction A and temp A rating, which a good all-season tire should have. And for my uses, a treadwear of 600 or higher. That really starts to narrow options down.

I always like to use this real life example to illustrate. Way back in the day, when a car had summer only tires, there would often be a warning for wear. Maybe for owner satisfaction reasons, not legal ones.
My 2007 BMW came with 140 A A, Bridgestone RE050A's. They had 41k before I replaced them. Fronts still had life, but rears almost bald. So the 140 truly was irrelevant. Couldn't tell you what the current tires have for a rating, they're 10 y.o. Pilot Super Sports (sat in my shed for a few years lol unmounted).

These won't!
On the other hand, Continental ExtremeContact Force will.

Funny today at the dentist’s office, the hygienist told me she’s getting Crossclimate 2’s and that they are all weather, not all season tires. I was impressed to hear that from a 20 something year old. I had to flex and tell her yes they’ll have the three peak mountain snowflake symbol just like full blown snow tires 
I truly love when young folks research large purchases. She said it will be just over $900 installed. That’s why I say many will be just fine.

Haven't watched this video, but his video on tire wear was really good.
According to Continental the type of vehicle, your driving style and the type of roads are bigger factors affecting wear than the type of tire you are using.

I didn’t appreciate tire selection until I crashed a motorcycle and started off roading. Now tires are the number one thing care about on any vehicle.
20%? Try 90%!

I think tread wear ratings are fudged a bit in both directions and used for marketing purposes as well.
My Ferrari came with Pirelli P Zero Corsa tires with 60 AA A. They wore much longer than the 60 rating would imply. I think Pirelli was exaggerating the tread wear rating to emphasize their track focus/worthiness. Their newest version now has an 80 rating.

I gave up on all season for my BMWs and use summer tires year round in Seattle. I do drive in cold and rain. I have found summer tires will generally outperform all season tires in both dry and wet. And all season suck in snow, at least in my experience (last set was Michelin PS AS 3, but also Conti DWS), so I'm not giving up anything, I just park when it snows. Never had any issues using summer tires down into the upper 20s, just slow down, as you will lose some ultimate grip....but nothing I would ever consider dangerous, even if driven a bit "spiritedly".
I run these on my E46. Surprisingly smooth and supple yet dizzying side grip when they have heat in them. A fantastic tire!
