Don't use UTQG reading 100%

Many times I have said to follow UTQG rating but not 100% since many say some tyres high treadwear rating but fast wear off, some AA traction but traction not really there but of course there are other factors like road, car, weather etc..

Just read Tyre Press on EU tyre label and it seems some tyres do not perform to it's label.

Controlled environment. Once outside, car differ, weight differ, camber, alignment, road condition, route, weather and so on......

Certain tyres purposely built for dry so traction rating is A.

Got from tirerack:-
Traction Grades
UTQG Traction Grades are based on the tire's straight line wet coefficient of traction as the tire skids across the specified test surfaces. The UTQG traction test does not evaluate dry braking, dry cornering, wet cornering, or high speed hydroplaning resistance.

The Traction Grade is determined by installing properly inflated test tires on the instrumented axle of a "skid trailer." The skid trailer is pulled behind a truck at a constant 40 mph over wet asphalt and wet concrete test surfaces. Its brakes are momentarily locked and the axle sensors measure the tire's coefficient of friction (braking g forces) as it slides. Since this test evaluates a sliding tire at a constant 40 mph, it places more emphasis on the tire's tread compound and less emphasis on its tread design.

Real world test and feedback is always the best....

 

As bro. ixeo mentioned, it may differ between manufacturers but actually there is a standard but whether they follow is another matter.

Standard are as follows:
In 1997, the UTQG Traction Grades were revised to provide a new category of AA for the highest performing tires in addition to the earlier A, B and C grades. Previously the A grade had been the highest available and was awarded to tires that offered wet coefficients of traction above 0.47 g on asphalt and 0.35 g on concrete. Today the grades and their traction coefficients are as follows:
Traction Asphalt Concrete
Grades g-Force g-Force
AA Above 0.54 0.38
A Above 0.47 0.35
B Above 0.38 0.26
C Less Than 0.38 0.26

 

If off by 0.01 then the feedback won't be too far off, but for some the wet handling & traction is a big gap....lol

 

Why I say real world test is best. In the past when forum was very hot time, many login and there were plenty of feedback. I collected the data as how many good feedback, feedback on what is good and what is bad and so on. Like bro. 6UE5t mentioned the more good feedback basically that tyre will be good, 50/50 good and bad then average and if more negative sure not good already.

Like Falken ZE912 when it was launched, many tried and the feedback was really good, and when people ask for recommendation this was one of the popular ones. Even the tyre shops I went to the boss mention the sales very good, must be you recommending....hhahahha Then after a year or two there began some negative feedback of fast wear, less traction and later we found also the traction rating before was AA and the current ones were now rated A only. From there the recommendation stop, as feedback was bad and I think that is how it died a natural death.

Nope, the difference is between expensive and budget tyres......hhahahhahahha

That time RSRR not out yet? After his hero sold off the rims and tyres were sold too, so no need RSRR already.....lol
