Cross rotating:
Helps keep the belts from bunching. You can cross rotate directionals for about 50 miles, and that will help stop the pulling. RK PS Before you contest this, I recommend you read the Goodyear and Khumo tire service manuals, and the Bridgestone/Firestone store said they do that for pulling.

I just did a quick check of www.goodyear.com and www.kumhotire.com and am unable to find any reference to the assertion you make. Have you got a URL handy? -- Tegger |

Sorry:
I just saw it in the manuals that my wholesalers had. One day, I might be able to swindle a photocopy and post it. Tire companies have a lot of non public information. I think it's all part of helping sell their ****.I used to be a Good Year, and nothing but Good Year seller, now whatever the customer wants is what I sell.

Excuse me but,
I never made a claim that this information was online. As for your assumptions. I guess you keep yourself in that crack induced daze.

But I find it kind of difficult to believe the belts could be "bunching". Seems to me if they were actually shifting like that every time the tire rotation was reversed that the tire would eventually fall apart. The only tire Service Manuals I've been able to find are for truck tires. And they make no mention of belt stability. I've found some mention of "bunching" in documents describing tire manufacturing, but these do not seem to relate to any sort of belt shift during use. -- Tegger |

Directional or NON directional tires? What to buy? Cooper?
Hello:
The main reason tires pull and wobble is that: 1- The belts tear, and you get a bulge in one area, no matter how small it is. It will cause pulling or a distinct bump, higher at higher MPH. 2- Belts separate, and again you'll have a lump on the tire, or a low spot. (Sort of the scenario where a tire always looks low, no matter how much air is in it.) 3- Cords bunch, and the tire actually becomes like a wavy lock washer. If you roll it, It will wobble more than roll. Sometimes these imperfections, are so small, that you can not really see it. So that's where your sense of feel comes in. Rotating removes these problem areas, or at least move the belts or cords to their appropriate areas. This happens to directional tires too. That's why the manufacturers say in their proprietary manuals to rotate. Hunter makes a balancer, which I think is called the: "Roadforce" and it tells you at least 4 different ways to set up the questionable tire. Even to mount a directional tire backwards on a rim, and reverse the rotation. I'm sorry for the misunderstanding, but I'm sure if you know a Good Year, or a Bridgestone/Firestone technician. They'll tell you what their factory manual says.

It's been my personal and extensive experience that most tire vibration is due to poor mounting. Most tire "techs" seem to be poorly trained and use the wrong procedures (and materials) for mounting the tire. Many times I have seen condemned tires redeemed simply by remounting them properly. The definitive test: Raise car off the ground so the tires are in the air. Start the engine, put the transmission in gear, and allow the engine to idle. If one wheel does not spin, give it a push-start with your hand to get it going. If the tire tread does not spin *dead-true*, it has been badly mounted and will vibrate, either now or later. The tread on an improperly mounted tire can wobble side to side, hop up and down, or both. If you study the side of a wobbly/hoppy tire immediately adjacent to the rim, you can often see how the bead is unevenly seated, with some parts seated deeper into the rim than others. The worst part is that a newly-mounted tire that has been improperly mounted can seem OK at first, but will get worse over time as the tread wears unevenly. Unfortunately, the tire will get blamed, not the monkey who installed it. -- Tegger |
