YOUR symbol is missing the numbers. Why would this happen per government requirements?


Nope:

Regular (non motorcycle) "Pneumatic types" is apparently CNS 1431-2014 but their search is broken for me. Suspect the "R41084" is a registration number.

It would have an A and B part number.

Agreed, not a directional tire.

Agreed, not a directional tire.
The description of the tire on the Sears site (as the OP posted above) says:

"Advanced directional asymmetrical tread design combines performance, touring and traction benefits."
 
The left side of the tread doesn't look like the right side. So it's asymmetrical.

But if it doesn't matter for water evacuation or wear patterns it doesn't have to be directional.

The original goodyear aquatred was directional but the tread was a mirror image, so not asymmetrical.

I would want an oddball tread like that mounted "correctly" on all four wheels if for no other reason than it wouldn't look dumb.

PS there's a michelin tire literally called the "symmetry" and it looks "boring", a good thing:

And why would you call and argue with Discount Tire about it? And not believe their response? We've taken the customer is always right thing way too far. Not just here but in general. They sell tires. Lots and lots of tires. Who are you to argue with them? Even the person answering the phone knows more about tires than you.

Off road racing may need directional and asymmetrical tire.

I learned about this unusual tire from an Australian poster.

For directional tire you can flip it on the wheel then mount on the other side of the car. For asymmetrical tire you can cross rotate.

For directional and asymmetrical tire you only rotate front to rear, you can't flip it nor cross rotation.

I have Goodyear Assurance Tripletreads, and they have DIRECTIONAL arrows and notations on the sidewalls. Of course, my arrows are shaped different than yours, they are different tire brands.

I can post pics if you like, but, as stated, they are different brands of tires. Other than all the "standard" nomenclature which MUST be on a sidewall, I know of no "standard" way of noting "directional" tread.

R41084 is marked on the tires next to the symbol. That is CLEARLY the Chinese registration number affiliated with that Chinese symbol/tire brand. That is not a directional tire symbol. The 30001 number is just a generic number, one obviously not affiliated with that brand of tires. Your entire post is wrong.


Gee, I'm all grown up and I've been wrong before, and I don't mind being corrected, I kinda even like to learn, but if I'm so totally wrong, then so is sears.com...

The point was I was un-clear about the symbol and was not given the chance to argue with the company.
I always question, and I am usually more informed that the so called "experts"

No, Outside and Inside are clearly marked.

Going with the recycle theory for now...


It is a Chinese BMSI (Bureau of Standards, Metrology & Inspection, M.O.E.A., R.O.C.) marking.

That's what I was thinking. Therefore they should be on the passenger side of the vehicle


No here is my dilemma, I specified symmetrical tires so I could rotate them between sides. The tires were purchased on-line from Discounttiredirect.com Here is the discription from the website: Features & Benefits
Advanced asymmetrical tread design combines performance, touring and traction benefits.

Now here is the same tire on sears.com website:Features
Advanced directional asymmetrical tread design combines performance, touring and traction benefits.

I phoned before delivery and Discount assured me that returning the tires would not be a problem if they show up with a directional arrow.
When the Tires arrived I phone Discount back to tell them that they may be directional and Discount was not very friendly and held their ground telling me the tires were not directional.

I have sent emails to Nanking corporate and Tireco the distributor asking what that symbol is. http://www.nankangusa.com/tires/performance/nankang-1

I have yet to receive a response....

I am not happy with Discounttiredirect.com.. plus there is no email on their website to dispute. Phone calls are rubbish....


Asymmetrical does not mean directional. The Eagles on my Vic are asymmetrical, but can be cross-rotated.
 
Even symmetrical tires will mess with your head it you look at them. All 4 tires are the same, but any row of angled tread blocks are different when mounted on both sides of the car.
Really obvious with the old General Altimax T-rated tires. They looked directional, but the were symmetrical.
 
Have you tried looking on both sides of the tire? If that symbol is on both sides, and it's pointing in different directions (depending on which side it's on) then it CAN'T be a rotation direction indicator.

Yes, we learned a new symbol, but also that people can argue for three pages whether a tread pattern is directional or not, even if Nanking's website and Discount Tire Direct make no mention of directionality. But Sears.com says it's directional, and they know everything.

Look at the tire for pete's sake, it's not directional.
 
These are great tires! do not hesitate to buy this brand. I have been on these for about 10K miles not they are staying balanced and still smooth and quiet. Love the grip.
