1) Dave posted more links to state his theory than YOU have.

2) You are CLEARLY the one with a hard on for Dave. As YOU have way more posts attacking his credibility in this thread than I confirming your lack of credibility.

3) Why don't you spend more time posting the links we asked you for before asking someone else for theirs?

 

I don't see the harm in asking for where he found this information. I wasn't the only one that asked. LOL!

Jeff you need to chill out.

 

Neither do I see any harm in asking for links to proof your points. The problem is we never got them. See how that works? See the hyprocsy?

 

Grow up Jeff. Mod asked you to stop, but your ignoring his request. Now back on topic.

 

Russ, you're not a moderator. The moderators do not need your help in reminding people about the rules.

Jeff & Russ: drop it. Any more posts in this thread along these lines will be deleted.

 

i only did the fronts on my car, so worst case is i get some under steer and slow down.

 

Thank you for your email. We appreciate the opportunity to serve you.

A directional tread design is intended to be run in one direction to
maximize handling and traction capabilities. If you run it in the wrong
direction it will diminish the handling and traction capabilities that the
tire was designed to deliver. It will not damage the tire itself but it may
not wear properly.

Thank you for your question about Michelin tires.

But on the topic of uni-d tires. Not sure what an email from Michelin is going to prove one way or another. As the reply wouldn't be stated for truth but for avoidance in litigation.

 

About what I expected. It's funny that they're UK site site says you can run direectional tires backwards in order to fix certain wear problems. Regardless, he basically reiterated what I've been saying all along, certain traction/handling situations (ie rain/slush) driving may be impaired by running the tires backwards. In terms of dry handling, there is absolutely no difference, at least with my Avons. I've thrown the car into some pretty rough manuvers just to see if it was going to exhibit any odd at the limit handling behaviors. I can't comment on the others that are running different brand tires backwards.

It's good to see that even they admit that the tire will not be damaged. So many think that running a directional backwards will some how result in a blow out, ply separation, or some other serious issue.

Finally, if you're going to do this, make sure that your tires are only directional and not asymetrical directional. There is a difference. An asymetrical tire has varying tread designs and rubber compounds across the face of the tire. A standard directional tire does not.

 

Dave, I don't mean to nitpick, but I have a problem with that statement. While I certainly believe that you haven't noticed any differences, I find it hard to believe that you'd be able to pull any maneuvers on public roads that would be extreme enough to allow the differences to be noticeable. In fact, I don't think you'd notice the difference until you did something like autocrossing. Of course, that's just my opinion.

On the other hand, that means that for everyday driving and possibly even some less exaggerated emergency maneuvers, that reversing the direction of those avons has no impact on everyday driving.

 

Isn't the actual belt on the tire made to go one way and going the other direction for a prolong period would cause that belt to get weak? Just a thought.

 

Reading is good

 

LOL

 

While I don't have an issue with your carefully calculated short term remedy to improve the tire roar I don't agree with this:



That's not what was said but how you are interpreting it, to support your original statement. Once again he said:

He is saying it will diminish the handling and handing capabilities the tire is designed for. No mention of only certain handling or traction conditions as you're purporting. IMHO, that is a difference and it applies to all conditions the tire would be subjected to.

 

I'll try to set the record straight here. The manuvers have been done both on the street and in a very large open lot that I frequent that allows to handling tests, tail-out manuvers, test launch techniques, braking, etc. I can safely attain 50mph within the lot which is new, smooth, and free of obstacles. The reversed tires behave the same way as before. The tires make the same noises, exhibit the same mphs though portions of my so called course, and the tires break loose smoothly just as before. Nothing feels different. On the street, the cars has attains the same mphs when running through a particular clover leaf junction near my house.

The only negative thing I've noticed is a very slight increase in what I call graininess which is felt through the steering wheel. The graininess can probably be attributed to either the feathered edges running backwards and/or simply because the tread is running backwards.

Grip in dry and wet (not standing water) conditions is largely dictated by the rubber compound used and the amount of rubber that meets the road, not the tread design. There's a reason why race cars use slicks or shaved tires. The more a performance tire gets the worn, the better it handles, responds, and feels in the dry. Additionaly, the more the tire gets worn, the worse it handles in inclement weather.
