I just bought a set of axis pentas from another member of the forum and now have a shudder over 70mph. I really like the wheels and would like to keep them.
They have had a high speed balance in the last two days
Nissan just completed an alignment yesterday
Lugs do match the wheels and
the centering ring is on.
Any other suggestions?

 

No clue on how to solve this. All I would do is make sure all the lugs are tight and everything is snug. I use to have rims on my older car, and also felt some more vibrations at high speed over the stock wheels. However, if the vibrations are severe, you really need to get the rims off for your own safety. You don't want to end up in a crash or tipped over because you wanted your wheels to look nice.

 

I had that in a motel bed once.

First of all, did you buy used tires with these rims also? If the problem is not with the used tires, the rims are either bent or not rounded. Have a tire shop checked them both the tires & rims.

 

have them rebalanced from a good tire shop you can trust. And check the tires for weird wear.

 

yah ...i had this problem before on my wrx...tires just werent balanced properly...do what Zspectrum said.

 

Yeah the tires came with the wheels , Falken F432. I am going to have them recheck the balance in the morning and then if tht doesntfix it go out and buy a dial indicator to check the wheels since one wheel does have some curb rash.
