Deflation - Inflation question: do you guys use portable electric pumps to inflate / deflate your tires? I presume you reinflate them on the spot and don't go to the petrol station after each excursion. If yes, which pump do you recommend?
Text Update - Interesting mentions: 1. The fact that if the rear wheels are on the earth-stair, then the car climbs much easier compared with if the rear wheels are directly above on the ramp. Most likely, the engine requires less effort to cope with the back wheels and and thus all 4 wheels have a greater margin for traction deployment until the grip is lost. Having more time to move the car and get into optimum traction looks like a good thing, otherwise it risks coping too fast with the car weight when the breaks are released on the ramp and they start skating/spinning on the spot. 2. The fact that on the same ramp you can spin-slide or climb depending on the pressure in the tires or due to the the traction-grip from a little more inertia, helps with identifying more easily the design differences between the tires. 3. The steps/stairs of the ramp help to reduce car speed-inertia and force the tires to lose their grip if you have too much speed (the front will bump too high), so this result will force the drivers normalize speeds much more than more than on simpler ramps. NOTE: The video editing and the analysis work, takes almost twice as long as the tests themselves. Please then don't forget to share the video if you want to motivate such community efforts. Thank you.
@@DaciaDusterTrails : O thank you very much for your help! It doesn't snow where I live so I guess they would work the same for me? I mean the models Discoverer and Evolution
Well done on the video! Technical language questions: What does +/- 15% more surface spin traction mean? Does +15% more inertia means build +15% more speed and sustain it?
In our book, there are two big types of traction per wheel, traction crawl (when the tire does not spin) and traction spin - when a tire has high revolutions and spins very fast. As for inertia yes, you can see that you need a bit more initial speed (longer initial distance, more car inertia) to get the same result.
Yeah, I find that my AT34s perform WAY better at about 1.8 ATM 26 psi is GREAT. 1.4 ATM or about 21/22 PSI, I find that the sidewall treads don't really have enough grip, and sometimes when the pressure is too low and you drive on the sidewall, you'll lose traction when side hilling, etc. So, I would say, don't drop below 24 PSI probably unless you're on flat ground or unless you're trying to get unstuck. Great point about protecting your engine! I guess more wheel spin DOES mean higher engine RPMs, after all. Great point!
Hi! Thanks a lot for all your videos, they are super helpful. What's the fuel consumption difference between the AT34S vs the stock tires? I have a 19' 4x4 BlueDCI Duster and I'm now about 6 L/100 km with the LX2 stock tires. Thanks!
As for Michelin Latitude Cross, we only tests ATs but from members feedback we cannot say much about it, there is nothing impressive about it nor very bad. Its a street tire, it does not shine in offload more than any other all-season.
@@paulomigueloliveiramartins385 Its a very old article with some very silly aspects in the review, he's comparing an all season on asphalt roads with an Mud tire, then he obviously explains its not good in mud, then a huge amount of comments about mounting the tires on rims. As you can see we test tires much faster visually and objectively rather than drive a full expedition just to feedback them with generic comments. In any case, we contacted Michelin for help in getting them for testing, if they are confident in their product or do care about 4x4 community testing rather than bloggers or journalists, they will help, if not we will depend on what our members have said in their personal experiences, that Michelin LC is a ok/mediocre tire.
Bunā am si eu o nelāmurire , în videoclipurile dacia daster , spuneți cā modelul Cooper Att, nu ar fi all season ,doar de varā, pe site-uri scrie : Cooper DISCOVERER ATT 215/65/R16 102H all season / off road,, acum care-i realitatea? 
Nu este all season, este o gresala pe site la ei. Adica avem si text in discutie cu ei in care spun ca este de vara dar si teste in care confirmam ca e praf iarna.
The vehicles are 4x4 but they can switch to 4x2, this way you can see when 4x2 fails but 4x4 works, so you can visually quantify a traction value. Also the vehicles are extremely light and thus they force the tires to work harder since their bite lacks pressure. Thus means the tire design and chemistry must work harder than the power and the car traction systems.
215/70 tires can be installed without problem on the standard suspension? How much cm lift you earn ?
You guys are professional
keep doing that great job yo doing.
Thanks, pls share and subscribe

Would you actually recommend Discoverer ATT? I'm looking for A/T tires for my Hyundai Tucson and I'm considering them.
No
@@DaciaDusterTrails what A/T tire is worth buying then?
Have you tried the Falken wildpeaks at3w?
What's the difference between the Discoverer At3 and Evolution ATT? They look very similar
ATT is a summer tire and NOT recommended for winter ;)

Thanks!
7-7.3L/100km guaranteed, More traction = More friction = More surface drag
@@DaciaDusterTrails Thanks! It a lot more fuel... Almost like the KO2. I'll wait for a comparison in snow with the ATT's...
@@fourbyforester depends on tire size and car weight manufacturer recommendations
@@fourbyforester no way, we are doing 2.5 to force the tires, to abuse them, to try to loose control, 2.5 is for testing only.
Very nice! I would like to see a comparison between General Grabber AT3, Cooper Discoverer ATT and Michelin Latitude Cross.

Hi Guys, have you guys done a review of the cooper at3 Sport 2
Yes... not finished yet the video
Beautiful video! 👍🏻
Is there anyway to turn off the tyre pressure warning light on the dash when fitting steel wheels?
Buy tire pressure sensors for the new wheels otherwise turn off the light with a diagnostic tool
saluit, le recomanzi pe un Mitsubishi Outlander?
Depinde de stilul de condus si teren
use the same :
Tire Dimention
Tire pressure
Same driver
And then you will have a great test !
Do you guys have any experience with cooper ATW？
No, but its an old design

ATM?
Atmosphere pressure, slight jargon but in fact is BAR, 1 atm = 1.01325 bar

What is the deal with doing all these tire reviews on crappy little 2 wheel drive cars? Traction is always going to suck.
The vehicles are 4x4 but they can switch to 4x2, this way you can see when 4x2 fails but 4x4 works, so you can visually quantify a traction value. Also the vehicles are extremely light and thus they force the tires to work harder since their bite lacks pressure.
