Is anyone experiencing a slight vibration between 73-82 mph? At the beginning I though it was that the wheels needed balancing. I have taken the van for balancing and alignment twice and I still have the issue.

I have a SE and it came with the Dunlop Sport 7000 A/S tires.

I also have the SE model with the Dunlop tires and don't notice any vibration. I would suspect balance or alignment but since you've done that twice already I don't know what else it could be. What did the dealer advise?

Dunlops, Michelin, etc....Any tire can have issues that will cause it to be almost impossible to balance.

I think the dealer switching you to Michelins is a great. I have nothing great to say about either tire, but suspect one or more of the Dunlops were defective.

I have the Michelin, and for an OEM tire they are pretty good. Way better than the $29 dollar tires on some Caravans.

Hope it works out.

Cheers!!

They swapped the tires but I'm still having the issues. I still have a slight vibration @ 74-76 & 78-80 mph. At this point I'm clueless and so are the techs, I know the must have me every time they see me going in.

Now that my van is over the break in period, I took it up to 80 mphs a couple of times, no vibrations at all.
I also have the dunlops.


some random thoughts:

1) lug nuts tightened too much-over torqued???
2) was looking for wheel locks and realized if the locks aren't within the same weight at the oem lugs, that might throw it off???
