Radial Tire Pull.

Well I heard of it before, but I never saw it first-hand. Now I've got it. I bought a used car about two years ago....little ricer car. It had brand new tires, an off-brand I never heard of. They were ok on dry roads, but were very noisy and slipped around so bad on wet roads it was scary. They did however go straight without any pulling.

I bought a set of Goodyear Aquatread III tires in Nov 2000. These have the latest/best traction rating (AA) and they do go good on wet snowy roads. They also are directional because of the tread...once mounted you're not supposed to rotate the tires to the other side of the car.

From the very first they pulled to the right. I thought it was because they were new. A front to back rotation didn't change anything. I waited a few months, then turned the tires around on the rims and rotated them side to side, which made the car then pull to the left. I waited a few more months, then tried running the front tires non-directional. Now its pulling back to the right. Finally broke down and did a full alignment..two times. The alignment was perfect.

It's the tires..radial tire pull. When you spin them in the air on a tire machine they look perfect. At 55 mph the car will drift out of the lane in 5 seconds or less, every time. What a pisser. I've got 13k miles on them now. They still go good in the wet, are very quiet, but they pull. The discount tire dealer I got them at doesn't believe me. So I'm stuck.

Moral: No more Good Years for me, no more directional tires for me. If you ever have this happen with a set of new tires, go right back to the tire dealer and scream.

That's good advice, I might be buying new tires soon since it's turning cold.

Thanks

that could have been because if you left the rotation for too long and they wore unevenly, then it'll pull when you rotate them

The crown of the road you are traveling will cause the car to pull to oneside. If the car does not drift, the road was not made properly.

I felt this a lot on roads that have recently been repaved. I believe the highway depts are starting to make some of the lanes a little more pitched for water runoff and hydroplane prevention. Check the balance on your tires too. If one is out of balance any, it can also pull. Vibrations only occur if it's REALLY out of balance or your rate of speed is just right.

I used to align cars with 1/4-1/2 degree more caster on the right side to compensate for the road crown. Worked like a charm on 90% of the roads. ;)

No, tire balance will not make a car pull.

If it takes 5 seconds for the car to change lanes, that is acceptable, depending on the road. No car will stay straight indefinitely.
"Radial tire pull" is a myth. It's nothing to do with the tires being radials, if you truly have a tire pull, it is because one tire is slightly larger in diameter than the other.

If you wanted to prove that the tires are causing this, swap the front tires from side to side. I know they're directional, but it won't hurt for a few miles.

If it is truly tire pull, the car should drift the other way.

I think he tried that....

Read his post!! He changed them over to the other sides and the car pulled the other way. Did the slope of the road change to match the tires??


If the tire people don't believe you, tell them you will let them drive the car to see for themselves.

Man, I'm glad to see I'm not the only one! My Trooper does the same damn thing. It's a radial pull to the right. :|

Alignment has been done three times on the computerized alignment machine with the laserheads that mount to the wheels. Tires have been balanced and rotated, etc. The only fix is new tires....these only have 18K on them!! Anybody got $600 they don't know what to do with?

Read the post. He made no mention of the type of road he was on. Was it the same one in both instances? It would not be a normal car if it did not pull because of the surface of the road. They ALL exhibit some pull.

It would be a heck of a coincidence if the type of road matched up with the different tire arrangements.

Look...like I said in my first post, I have tried the tires in every possible position, on many different roads.....it pulls. With the tires in their current position, I have to hold the steering wheel about ten degrees off-center to go straight down the road.

Also....when I removed the tires from the rims, remounted them the other way, rotated them left to right, the pulling changed directions.

Also...this car never pulled at all with the tires that came with it.

The manager of the tire store doesn't believe me...plus he says my car is probably out of alignment.

Whatever you call it, my radial tires pull to one side..and cannot be fixed without setting the alignment out-of-spec (plus I've only got a tow-in adjustment). Radial Tire Pull sounds ok to me. Over the years I've had at least fifteen different sets of radial tires on many different cars and trucks. Never had this happen before. It's real.

I've had one alignment shop do a car. Take it directly to another and they adjusted it differently. Our local tire/alignment shop has a setting that is wrong. The outside right tire always wears on the outside. I go elsewhere after 2 cars did the same thing.

If it were me, I'd get the alignment done at another shop and then ask for my money back if they cured your problem.

The other option would be to contact Goodyear about the problem. You might be surprised the interest they take.

Tominator.....The alignment was done on a new Bear (I think) alignment machine. The back wheels checked ok....they're not adjustable anyway. The camber and castor on the front were ok(they too cannot be adjusted)..only the tow-in needed a slight tweak. When I did the alignment the second try, it checked the same as after the first try.

I'm pretty sure the tow-in would not cause this pulling, even if it was way off. I might see if Goodyear has anything to say. Thanks.

Right, incorrect toe-in won't cause a pull. It may cause edge tire-wear, or mushy on-center steering feel, though.
