[@brianbanks3044]

as a tire and alignment guy for the past 25 yrs, I can appreciate all the upgrades in tire engineering and equipment to install them.....i have worked on Coats machines in the early 80s to Hunter machines of today and a lot of the technology has to do with TPMS, alloy and aluminum rims and very stiff and short sidewalls of tires...these weren't big issues in the 80s and 90s for mass tire installations...but as cars got lighter and materials weren't steel anymore, the equipment had to change with the designs...as a big truck alignment mechanic, I saw the differences in a 250 dollar tire and a 400 dollar Michelin and YES, there is a difference...the same goes with car tires and cheaper tires, you get what you pay for a lot of the times.....a video on worn tire testing would be a great idea because all new tires perform pretty well...it's the ones that are half worn and can't drive through a small puddle of water or a wet highway that are the ones to be concerned about...great video and i think you are just scratching the surface on what you can make videos about...thanks

[@thetechlibrarian]

[@DougPowell01]

The randomizing of the tread pattern is a principle that was also used on the highway system. Expansion joints in the road were once equally spaced giving the tire noise a similar effect we often associate with railroad tracks. It was found that this can have an effect on car drivers which would tend to make them drowsy or even put them to sleep. Nowadays, there are 3 or 4 standard spacings, randomly installed to minimize this problem.

[@crusinscamp]

Long ago, on a long highway trip, we drove by a car on a concrete highway with regularly spaced expansion strips. The two guys in the car were doing an exaggerated "bounce" in their car seats every time they hit an expansion strip. It gave us a good chuckle.

[@HughesyTech]

Awesome video Andrew, and well done on the re-branding. I've been a sub of the dash cam reviews for years but these documentaries are fascinating!

[@TesserId]

[@TesserId]

@DeathNikki Well, it isn't what it was a decade or so ago.

[@datasailor8132]

I was an early adherent of radial tires, having Semperit Supersports on my 1962 VW Beetle in the mid 1960s. Because of this or that I had the fronts mounted a week or two before the rears. The difference in those weeks was incredible. After all four were installed the difference was phenomenal. I never went back. If you ever drove a Beetle, you know how wiggley its read end was.

[@eshafto]

I went from bias-ply to radials in 1977. The difference was astonishing. If I had to drive on those old tires today, I'd be terrified. I can think of times I came close to dying, when I would have been perfectly safe on better tires. For some reason, I still buy the cheapest tires I can find, though. Maybe it's time to re-think that.

[@lukestrawwalker]

Bias ply tires still have their place, though... they're particularly good for trailer tires, as radials just don't hold up. I've had bias ply tires running just fine on a cattle trailer for over 20 years-- only reason I had to replace them was the rubber dried out and the tread layer peeled off, even then I drove the last 20 miles to an auction barn on the exposed strings of the plies LOL:) I wanted another set of biases but the tire shop didn't have any so I had to get some of the "new, improved" Goodyear radial trailer tires. I'd heard that radials were lousy trailer tires but the dealer insisted they were fine, just keep them aired up to 60 PSI when parking the trailer between uses so they didn't develop "flat spots" that weaken the plies. Well, they lasted about four years and blew out hauling a load of calves. Had maybe 600-800 miles on the tires. I went back to biases and no problems. I will ONLY buy bias trailer tires from now on. OL J R :)

[@rachelblack3816]

I remember when I was a kid, once I had used a mix of radial and bias-ply tires due to economics (I was poor). With that mix of tire types, my car (1964 Dodge Polara) was almost impossible to control! It scared the daylights out of me to even drive it at 40MPH. Having clearly seen the issues of mixing tire types, I never did that again. So thankful when radials became the norm and bias-ply tires disappeared from passenger cars altogether. The engineering that goes into tires is amazing!

[@lukestrawwalker]

@@rachelblack3816 Yeah mixing biases and radials was a big no-no, particularly radials on the front and biases on the back, IIRC (could have been the other way around, too many years ago to remember exactly). Basically the sidewalls flex different in turns which creates "understeer" or "oversteer" going around curves, or as the weight of the vehicle shifts with slight steering corrections, which amplifies the motion. Radials are good for some things, and not so good for others. For trailers IMHO biases are still FAR superior in longevity and weight-carrying ability, at least for smaller trailers. Later! OL J R : )

[@rachelblack3816]

@@lukestrawwalker I had always wondered why trailer tires, and from their appearances large truck tires as well, were still bias-ply. I guess that explains why! Thank you.

[@gravemind6536]

No it is true budget tyres suck, need at least mid range or upper mid range tyres to have good tyre performance and safety.

[@lukestrawwalker]

Yeah sure... remember those Goodyear tires that were tossing their tread and killing people driving Ford Explorers?? My '92 F-150 came with Goodyear Wranglers from the factory, I was like "wow that's the best set of tires I've EVER seen on a new vehicle!" as all our previous trucks had the sh!ttiest tires Ford could get on them from the factory. Well, the stupid Goodyears must've been made out of old eraser rubber... those things were SLICK BALD at 25,000 miles! I usually keep old tires to use on farm trailers and implements where tread doesn't matter, but these were SO slick that I couldn't even use them for that! GARBAGE! Best tires I've ever run were the Continental Conti-tracks. Ran those on my pickup for years, until I couldn't get them anymore because they stopped carrying them. They were a 60,000 mile tire and they'd run every inch of it before they needed replaced. Since then I've just been running the cheapest tires I can get, because I've never had a set of Goodyears or Firestones be actually worth what they were charging for them. They'd either wear out or fail long in many cases before reaching even a paltry 30,000 mile wear. Later! OL J R :)

[@btbb3726]

I had two consecutive vehicles that used the same tire size. I was also putting a lot of miles on my vehicles over the time when I owned said two vehicles. Consequently, I bought “several” sets of tires. What I found was that some of the highest priced tires actually ended up being the least expensive because of their practical longevity. They were also the nicer driving/riding/performing tires right from new.

[@epock7]

This is the first video I've seen of yours and it's excellent! It's easy to ignore the small details in the engineering of products which make a huge difference in performance.

[@Jonathan.D]

Another great video with lots of valuable information. It kept me engaged from start to finish. The Tire spreader that looks like some kind of Spanish Inquisition torture device for tires can still be found in many tire shops today. It makes it easier to inspect and repair damaged tires. This is very useful for tires with a tall sidewall. When you patch a tire you have to slightly grind the inner surface of the tire so the patch can properly adhere. Low-profile tires are easier to inspect & repair but are much more difficult to install and remove. With the old tire machines, it was very easy to damage a low-profile tire when trying to break the bead from the rim. This is because there's almost zero flexibility in the sidewall of a low-profile tire. I might be wrong, but I was thinking that car and driver magazine did a test of a few tire brands to see how well they lasted over their lifetime. In any case, it's your attention to detail that has brought this issue to the forefront. Great job and I look forward to seeing your next video!

[@jasonmorehouse3756]

it's not a cheat, its a tradeoff. if the sipes go all the way to the bottom of every tread block , the block loses rigidy and will bend and twist causing a squirmmy feel as you drive and it will create more heat in the rubber making it wear even faster

Awesome video. I work in collision repair and I can honestly say I've seen literally hundreds of cars come into my shop and the customer says they don't know what happened but they pressed the brake and they lost control under damp or wet conditions. And 99% of the time they had cheap tires w plenty of tread but the sipes were completely smooth. A large number were also the cause of blowed tires where defects in the tire were at fault.

[@brmbkl]

honest question; how can tires be so worn out before someone at the inspection catches this?

[@BAgodmode]

I’m impressed with the amount of engineering that’s gone into tires since I started driving 20 years ago. I drive huge pick up trucks. The latest set of tires, ultimate all weather performance, and a ride smooth as a Cadillac. You become a tire nut when you have to buy truck tires, trust me. People with cars don’t feel this pain normally, and a blown tire isn’t all that bad. On a truck, for a trustworthy tire (something you need when rolling with 3 tons pulling 5 tons) you’re not getting out of it less than $300 a tire before mounting.

[@dannypeck96]

motorcyclists are similar, but for different reasons. for us its less the cost and more the fact that a ditchfinder is death rather than injury. us bikers will argue PASSIONATELY about the "best" tyres. for me, I swear by road 5's for my fazer and city pro's for my cbf.

Just found you, watched this video and the one before, very pleased that there will be more content like this! Super educational and awesome!

[@luckyguy600]

Very good. I always like knowing new stuff, and things about old stuff I never knew before. Thank You.

Hi Andrew, for 4 months I've been waiting for your next video. You are doing an awesome job!

[@Jessassin]

Great video!

0:20 The Apple of tire machines? You mean, when your tire's too flat, you gotta go back to the dealer and buy a brand new car?

[@rezabasuki3293]

Great video, great explanation. Please keep them coming!

[@ClaytonHT]

This was super cool! I've subbed. I like your voice and the way you structure your content.

[@AdrianHernandezObradors]

This two high quality amazing videos in a row has made me turn on notifications. Keep it up! I'm loving them. I'm sure you have lots of ideas to continue making videos, but perhaps a good follow up to the road barriers would be one addressing the changes they made to make them safer to bikers?

[@vendomnu]

Just a thought: When you temporarily go off on a tangent to prove a point, it can be slightly confusing to figure out if the entire topic changed. What about an watermark in the corner of you and a bear (bear-with-me) during these point-makers?

[@Lam]

I really appreciate the feedback. I'm guessing that's regarding the car crash section? I think I might do that or another method to help indicate that this isn't exactly on topic but it has a point I want to make

[@Oneye.]

@@Lam Joe Scott (Answers With Joe) has a "tangent cam" he uses when talking about things like that. Great video BTW! I loved your last one and was surprised to find out it wasn't something you did regularly, glad to hear you're going to be focusing on it.

[@allenkennedy99]

Though I think creative use of chapters is acceptable instead, I can't see how such a thing would hurt.

[@atreyusmith3509]

This was amazing and great editing too! Great pacing and very informative! Keep it up

[@CodetheThings]

Just came across this randomly. Subbed. Great job, keep it up!

[@cuthbertallgood7781]

Really, really well done production, along with being far more interesting than I expected. Great job!

It seems to be a simple object but there's a lot and engineering and R&D behind it. Thanks for this amazing video.

[@1whospeaks]

Not an engineer, but the ingenuity blows me away every single time. From Machining to Coke Cans, I'm honestly shocked the human mind has the capacity for such elegant solutions. God Bless.

Great video I could watch a whole series about tires like this! But I'll wait for other interesting topics which I'll surely enjoy

[@ClickX2]

This was the first time I have seen anything by you. This was really great. Very informative and interesting. I am now a subscriber. 😊

[@mrad2009]

Great video! The tire you show with the sipes that aren’t full depth is made by General Tire which is a Continental sub-brand. I’ve always held sub-brands in roughly the same esteem as their parent brands, could you do a video on sub-brands vs parent brands and how corners are cut? With increasing inflation, people are trying to save money where they can.

[@ignftsandcryptos2650]

Who saw the squirrel?🥴

[@scottw9091]

This was an excellent insight into tires that I'll forever look out for.
