High speed death wobble!

[RonH]

Running correct rotation besides the rain thing keeps the tire rotating with design in mind to keep cupping minimized. I run a front tire on a GL1800 correct rotation, then flop it reverse at about 10,000 miles just to make the cupping reverse to the exact opposite area. I doubt running a new tire backwards would have any effect that could be felt. I still bet the tires are fine, just let them wear in a little, but since the shop put one on backwards, make them swap it over just for principle.

I love these tyres, they make it easy to scrape the foot pegs ::26:: and get good miles too

Ridiculous mistake; shameful.

The last guy we had with tyre problems, in Aus, found his wobble issue lay in the simple fact that his wheels had been balanced using the old static method. Make sure whoever re-fits these is certain the tyre beads have 'popped' & are even at the rim, then dynamically balance them before the re-fit. Obviously a double check of the wheel bearings should be a standard procedure, & just make sure, as others have suggested, that the steering head bearings are OK & correctly adjusted.

Sounds like you are about to get your old bike back again ........................ KEN

Nothing wrong with static balancing done correctly. If you stroll the pits at a MotoGP or Superbike race, you'll see the tire techs using static balancing rigs. When I was a kid working in a gas station / tire shop, we would occasionally get a customer back complaining about a vibration after installing new tires. We'd dynamic balance them again and there would still be a vibration. We would finally resort to static balancing and that always solved the problem.

Whilst not sure I can agree entirely, I can accept that done carefully, accurately & with patience, a good result can be achieved. I can only speak for the UK, but it would be rare to find a busy tyre shop these days that possesses all, indeed any of these attributes. Over here our market is price/volume driven, which leaves a dynamic balance the most time effective.

The guy who fettles my old Electraglide for me uses the static method, takes his time (for which I pay) & always does a thorough job. But then again, this is no sports bike, so any dynamic rotational error would not be magnified in the same way.

Each to there own; it's usually pretty obvious if a new tyre combo is out of balance, but not always quite so easy to get it sorted promptly, particularly if you had the change made to loose wheels.

I static balance and never had a problem with it. I can probably have it set up and done as fast as my local guy with the dynamic, too. He has to set up the bike and I've already got the tire off.


With the old belted tires, if there was an arrow, you really wanted to make sure you complied with it. For most radial tires and as OldRider wrote, the only reason to go with the arrow is for the rain sipes to function right. This isn't universal though.


The plies on some radials are laid to take the torque and cornering loads, so running them backwards means that the tire will not be able to carry rated load. Unfortunately, there's no way to know if any particular tire is a safe one to run reversed or not.

The main attraction of dynamic balancing is that it takes less time. That's why most shops use it. A proper static balance is somewhat time consuming. It was our fall back when dynamic balancing could not quite do the job. And as I said before if it's good enough for MotoGP bikes it's good enough for....

What is the difference between static and dynamic?

 

[bob dirt]

Dynamic is done with a machine spinning tire and wheel...static is done with a horizontal bar where you figure out where the weights go by watching the tire turn until the heavy part is on the bottom or a bubble balancer. Those are my redneck definitions. I remember using a bubble balancer when I in high school.



Did you fix your problem?

 

[Madhatter]

a friend had a rear tire on backwards and it gave him fits in the rain... felt like the bike might spin out at any time, was not happy with the shop that mounted the tire .... very unstable , but not head shake, other wise known as death wobble...

 

[DryRider]

Bob dirt they put on a new set of stock tires and I'm happy to have the confidence back in my bike. I'm sure I made a knee jerk reaction and could of had them just turn it around and been fine. I could not get myself to that spot. I wanted what I knew road well in the past. Now I'm back to square one...ha ha that's why I was going to change them I thought the stock squared off a bit fast. But I know I ride fast long and far I'm just happy I did not have to wear them out then change back to stock if they continued to be twitchy follow the cracks in the road and such. I know others have been very happy so I'm guessing they would have been fine. Thanks for asking. Ride safe.

I am in the habit of checking my rims for damage and that my tires are on the right way before I even leave the shop. If I got home and noticed, or worse put the wheels back on and noticed, I would then be mad at both the tech and myself.

I also use a permanent marker and put wheel rotation marks on my brake disks.

 

[RonH]

Best method is mount and balance your own tires. Actually even balance is not that critical. I balance now, but for years never bothered, and can't say I can feel any difference balanced or not.

 

[Ramseybella]

Wow! That was a great suggestion. Nice!

On top of that have them order a new tire, don't take no for an answer one bit, the tire has been compromised due to mechanic error.
I had Tire Kingdom (80's ::025: put four new tires on my old Dodge Tradesman 200 and I left the shop hit about 50 mph and all sorts of shit started happening..
Pulled over and found all four rims lugs never got tightened. Went back and chastised the manager in front of about 15 customers, he pulled me to the side and I demanded he take this seriously or I will go back out front and let everyone know how bad your service is. I got all four for free and never went back again.
