i took my car in to get the tires rotated....but they only rotated the front to back and vice versa...no criss-crossing....

i was looking in the manaul and it says to criss-cross them.....this is the 2nd time they did not criss-cross them....should i be worried? the mechanic told me they only criss-cross them if the wear is uneven...blah blah blah...i think he was full of shit and just lazy as hell....should i bring the car back and make them do it again?


also, this focker didnt check my tire pressure and the left front is at 25psi, while the right front is at 32psi.....will it damage my car if the tire pressure is significantly different?

anyone have knowlege on tires?

thanks in advance!

 

Front-wheel drive cars always go front to back, if the tires are symetrical...

Always, always, always...

 

Oh and to answer your second question...

If you drive on a tire that is low on PSI for weeks, then the tire will wear uneven, possibly causing vibrations and could even blow out (worst case). A day or two doesn't hurt anything...

 

no, the manual states different. criss-cross.

 

Call acura customer service or atleast call another dealership and ask them.

 

And the manual says the same thing on my wife's Alero... I think it's for a-symetrical tires. I could very well be wrong, but all front wheel drive cars that have four of the same tire (same tred design), should be rotated from front to back.

 

You've got it backwards.

Asymetrical tires cannot be rotated criss-cross without "flipping" the tires and remounting the tries on the rim.

 

What he said (Pull_T).. For sure call Acura Customer service, those tires should have been rotated according to the book. And for sure, the tire pressure should have been checked all around..

 

The fronts got to the back and cross if they are symetrical. The rears move to the front. Rear wheel is different.

The reason is that Left turns are typically easier on tires due to a longer turning radius and right turns are shorter radii so they scrub the tires more. So one tire will end up getting more wear if they are not switched.

 

Sorry, but a large number of asymetrical tires (and even tires like the Toyos that seem to be symetrical to a casual user) have to be mounted from front to rear on one side.


Comments:

1. If the tire has an arrow (or arrows on the sidewall) (like the Toyos do) that show the direction of rotation, you can't reverse the rotation. Also, there are a bunch of tires that DO NOT like to have their direction of rotation reversed.


If the tire has a thick sidewall (or protector bead) to protect the rim (rim protector), the tire will want to be mounted with that side out -- once again, it isn't too great and I don't know too many tire pros. that will reverse the rotation of the tire from CW to CCW. The tire protector needs to face outward if it has rim protection.

The bottom line -- have a very close look at the tires and when in doubt, call the manufacturer of the tire (perhaps more than once) to find out what recommendations are.

For those that have Toyo T1S Proxies -- they have arrows for rotation in only one direction and have sidewall protectors. They come in a right hand and left hand pair!!!!

Tires with that “Aquatread”(rain tire) like pattern only want to be mounted in one direction; they don't pump water if they are put on the other side of the car, with the direction of rotation changed. If they have a tread protector, LEAVE THEM ON THE SAME SIDE OF THE CAR!!!!

 

wow..that's great info eric! Keep up the good work!

 

why the hell involve acura over someones stupidity? call the service advisor of the dealership and tell them you want them rotated the right way, if you don't get any satisfaction ask to speak to the service manager

 

The purpose of regularly rotating tires is to prolong their useful life by achieving more uniform wear for all tires on the vehicle. Before rotating tires, individual owner's manuals should always be consulted for rotation recommendations for specific vehicles. If no rotation period is specified, tires should be rotated every 6000 to 8000 miles or at any sign of uneven wear. The first rotation is most imporatant.

Rotating the tires as recommended by the vehicle or tire manufacturer will help even out the amount of wear on each tire and extend the life of the entire set. Also note that some kinds of tires cannot be rotated in the manners as shown. Such tires include uni-directional tires and tires with asymmetric tread designs. Also, some vehicles may have different sized tires mounted on the front and read axles, and these different sized tires have rotation restrictions. Check the owner's manual for the proper rotation recommendations for these special cases.

When tires are rotated, the inflation pressures must be adjusted for the tires' new positions in accordance with the actual loads on that wheel position and the vehicle manufacturer's recommendations.

Underinflated or overinflated tires may result in poor handling, uneven treadwear, and increased fuel consumption. If the tires show uneven wear, ask the service person to check for and correct any misalignment, imbalance, or other mechanical problem before rotation

 

Not sure why you are quoting me here. You may have elaborated (and belabored) the point, but am I not correct with what I said here? :

I never said there weren't asymetrical tires that cannot be cross rotated, I was just clearing up what the other dude said. He was speaking in generalities, so was I, as most asymetrical tires could be cross rotated if flipped on the rim.

 

AND, what I'm saying is most of the modern "asymmetrical" tires CAN NOT be put on the other side of the car -- period. Don't change the tire's rotation. The keyword is: "unidirectional"/”directional” tire. Even when a tire is NOT unidirectional, there are quite a few people that I have talked to and they do not like to "flip" tires!

In case one -- to keep the tire protector or outside of the tire facing the outside (Someone cross-rotates from right-to-left or left-to-right by remounting ("flipped") on the rim on the other side of the car. (The rim protector or outside of the tire is facing out, but the tire went from rotating CW to CWW or vice versa.)

In case two -- the inside of the tire in now the outside of the tire *and* there are not very many modern tires that don't have some kind of rim protector and/or labeling that indicates which side of the tire is the "outside". So, now the outside of the tire is on the inside.

(I think I've covered the two mounting possibilities from left-to-right and right-to-left.)


Finally, even a tire with symmetric tire design SHOULD NOT BE "FLIPPED", meaning that the tire changes its rotation from CW to CWW or vice versa. IF the tire is "UNIDIRECTIONAL"/"DIRECTIONAL" it means what is says -- it can only rotate in one direction – period (There are arrows on the tire that show which way the tire is supposed to rotate.)


There are some tires that are not unidirectional, not asymmetric and do not have rim protectors; I don't think too many people here are using no-name, low-performance tires, retreads, or other tires that fall into that category. (And I still wouldn't flip them -- there are reasons, and tires take a "set")


"The generally accepted practice in the industry is to keep radial tires on the same side of the car. That means that you should rotate front to rear and rear to front without swapping sides.

When radial tires were new technology, they tended to take a set for the direction of rotation, and changing them to the other side often created a problem that caused vibration and sometimes even caused the tire to come apart. This seldom happens anymore, but unless there is a tire wear problem that you are trying to even out, or a radial tire pull problem, they should stay on the same side.

Some tires are intended to rotate in one direction only. They are marked on the sidewall very clearly. These should never be swapped side to side for any reason. --"



IMO -- I would never let someone change the rotation of my tires by flipping. If you want to do it with yours, you’re the boss in your own kingdom…

 

If a tire is flipped (on the rim) and then put on the other side (which I think is what they were saying), then the rotation is maintained.

 

It depends...

In one case, you maintain rotation, but you now have a tire that has the outside on the inside (you can't do that with my Toyo T1S proxies, the RE-730, S-02s, S-03s, etc, etc)

In the other case, the rotation is changed.


Two forms of symmetry -- rotational (CW vs. CWW) and bilateral (right sidewall vs. left sidewall)

 

I've never used them, but you're saying that some brands you have to buy a "left-Front" and a "right-front" pair? I don't see the advantage to such a set up, why would the inside of a tire be differant than the outside (when mounted on a car)? not argueing, looking for knowledge. tks. Ed

 

i think ericl is saying that there are left and right tires...w/o the front designations. these tires are designed to rotate in only one direction. so the question raised is - why can'i maintain the rotation by removing the tire, flipping the rim, remount it so that the tire still rotates in the same direction but on the opposite side of the vehicle. well, theoretically it's fine. problem is that some tires have a rim protector and/or thicker sirewall on one side. by flipping the rim and placing the tire one the opposite side, you've moved the rim protector/thicker sidewall to the inside of the wheel. that side of the tire that was supposed to aid in hard turning is now useless on the inside of the tire.
