Vibe with 18" wheels??

[330racing]

With my stock wheels and BFG tires I always noticed just a FAINT vibration at above 80....not hardly noticeable.....

I bolted 18s on my car and now at 85+ I get a weird vibration....hard to explain but it vibrates for a second , and then no vibration for a second , vibrates for a second, no vibration for a second..... is this an out of balance tire, or did I just make "the vibe" noticeable? Any input would be appreciated.

It could be something like a tire out of round that has a high spot. I would go to this website www.gsp9700.com and find a machine in your area. the Hunter gsp9700 will tell you if the wheels are running true and if your roadforce vibration is too high. If the roadforce numbers are high they will do a match mount by rotating the tire on the rim to get the lowest numbers. its worked for me in the past but if a tire is badly out of round you will not be able to get the numbers in an acceptable range and the tire should be replaced. its a simple solution to the problem as long as your wheels are true.

Forget the vibe, I want to see pics of the new wheels. :banana:

You are getting harmonics from the tire tread. Nothing to worry about.

Would I feel it in the steering wheel?

Dam nice looking car. Love the black wheels. I picked up a set of polished AFS 18x9 and 18x10.5 but have to wait until April to install. Dam you winter!

I had the vibe with both 17 & 18"...hopefully the new drive shaft
from ford will fix it. Picking the car up tomorrow.

Dealer told me the d/s is a new part number vs the original p/n
from the factory.

Absolutely. You may want to lower your tire pressure a little. Run 29 up front and 27 out back. If that makes it worse, go the other way. When you change tire size, you may have to adjust pressure.
