Dunlop Rotation Direction

[boston_kevin]

I just got finished washing and waxing the car for the first time since I bought her, and I noticed that the passenger side has the Dunlops mounted with the direction indicator on the tire pointing the correct direction (counter-clockwise). The driver's side has both Dunlops mounted with the direction indicator facing backwards (clockwise)... Since this obviously came from the factory like this, what are the implications of running these tires opposite of their intended direction.

I am confused here.

If your have uni-directional tires, then the passengers side should have the direction arrow pointing clockwise. The correct direction for the driver's side would be counter-clockwise.

Anyway, un-idirectional tires rolling backwards should still perform fairly well in dry conditions. Rolling the wrong direction in wet or snow will not allow the water or snow slush to flush out efficiently as designed as the water may be forced inwards with nowhere to go instead of out the sides as the tire rolls forward. You may get more hydroplanning as a result.

SInce this looks like a factory issue, cna you go back to the dealer to complain and get the right tires?

shows what I know about tires...

Last set of tires I bought were Mich. LTX/MS which aren't unidirectional. Thanks Olliebear.

If this is how the Direction indicators should be, I'll leave it... Seems a bit bass-ackwards if you ask me... Guess it's cheaper to do this than make tires for left and right.

They don' actually make a different tire for left and right side. They just mount them on the rims with the left and right side of each tire matching the side of the vehicle. This means that when rotating tires, you can only go front to back and not swap sides.

tires

They don't specifically make R and L tires, but performance tires are set up to be mounted and rolling in the correct direction (hence the directional arrows on the tires). So in that instance, there is a correct left and right. Once they have been mounted and run for about 1000 miles, they cannot switch to the other side of the vehicle because of the wear on the belts within the tire.

It just seemed odd to me to have the tires on one side of the vehicle pointing one direction, and the tires on the other side pointing the opposite direction. (Passenger side is pointing correctly for forward rotation of the tires, Drivers side is pointing correctly for reverse rotation of tires) ** Not talking about Tire Maintenance Rotation - the direction of rotatio **

Maybe we have a perception misunderstanding here. From your original post it sounds like the tires are mounted on the opposite side of the vehicle from what they should be.

"passenger side has the Dunlops mounted with the direction indicator on the tire pointing the correct direction (counter-clockwise). The driver's side has both Dunlops mounted with the direction indicator facing backwards (clockwise)...

I am assuming that when you refer to clockwise/counter clockwise, you are looking at each side of the vehicle individually. To me, if you are looking at the passenger side, directional tires should have the arrow in the clockwise direction for forward travel, and the drivers side should turn in the counter clockwise direction when you walk around to the drivers side.

If you're talking about the Dunflop Grandtrek AT20s that came on the truck when it was new, they're not directional. If you're describing the D> symbol on the sidewall, it's the Dunflop logo, not a directional rotation indicator.

BTW, these Dunflops are the worst excuse for a tire I've ever seen. Unfortunately my 2003 had the same pieces of junk on it too, as does my 2005. Even the dealer apologized this time for supplying the truck with them on.

looks like a good excuse

to get some Revos!

or some BFG A/T...

or some Toyo Open Country A/T...

If you refer to this:

It's just Dunlops logo, not rotation direction.

dumb dunlop

yea, sounds like if they did something that dumb, it is definitely time to upgrade.

Time for Revo's...
