A/T, M/T and alike: professional tests & comparisons?

While I do appreciate reports and reviews made by peers, it really really really bugs me that I've been unable to locate any reliable and impartial tests and comparisons of A/T and other offroad tires.

Now: a youtube video where a guy from some tire seller lays out four or five tires and talks about them for 15 minutes does not qualify. Neither does when some pro goes out and rips the hell out of tires given to him by the manufacturer. Needless to say, the driver is very pleased with the rubbers, and would definitely recommend them. Duh.

So an comprehensive test with measurements is what I'm after: this tire stops so and so compared to those. Feet/meters. How do they weat? 32's / 10k? How many decibels when going 60 etc.

Anyone know a source for this kind of engineering porn, please chime in asap 🙃

Something along the lines of this:
https://www.motor1.com/news/376024/d...-tires-street/

This one for example, gives the staggering finding that as a car with road tires has stopped under heavy braking, one with M/T tyres will keep on moving for further 21 feet. A whole cars length and then some...

Really? Nothing?

Here in the old continent we have lots of tire tests and comparisons available, but unforunately our offroad (or all terrain) "culture" is really undeveloped to say the least. So every god damned SUV and low profile rubberband gets tested, but not the A/T tires. I thought the US would be different, but apparently no...

I've used Tire Rack in the past to help me decide on what tires work better under specific conditions and other factors. Their consumer survey section for each tire is pretty handy.

JP magazine and FourWheeler magazine regularly publish tire test comparison reviews. You can also find the magazine reviews on the Internet. They give performance ratings for Street, Rock, Sand, Snow, Mud, Ice.

That is probably the best and most factual info you will find. Postings on 4x4 forums about tires, and "reviews" on retail websites are mostly useless due to the severely limited sample size.

As a general rule of thumb, M/T are loudest, wear the fastest, and take longer to stop, A/T are less so, and highway tires are much better. I doubt you will find any significant factual data on decibels/wear/stopping distance topics.

reality is people tend to run Mt and even At when they dont need either on a street mostly like 99.98% of real miles driven jeep. People as will do things to the jeep lifting that will make it handle worse. So stopping and other issue are all excepted for looks and cost savings. You can improve a lifted wranglers handling but it cost more and tends to not be made in China. Mts were not made for street really and when they get to far to that point they tend to lack and become more a At. why not run some Irocks they look bad, tough and are Bias.....I remember Bias tire on cars. ever drive a 500hp car on bias tires? hard to believe people lived through it. like driving on ice compered to to days tires.

Removing back space for wider wheels will effect the way it handles changes to scrub radius. The roll center of track bars and drag links changes ads "wag". when the axles shift excessively from center point in cycling. jeeps do it anyway but making it worse is not great idea as well.

next up Tire size today people want 37s on street jeep. ever have to change a tire from a high swing mount. when that tire and wheel is like 125+ pounds..... they dont stop as fast too, even with bigger brakes. stock 32s stop about as fast as jeep can and that is not saying much. But we are talking jeep so we make exceptions, like for the short bus.....
