New Rims, New spacers, New problems

[Tpilger]

Okay, maybe someone can help me out. I’ve had new after market rims put on almost a month ago and I still have some shake that you can feel in the steering wheel and sometimes through the floor between 30-70mph. I have 15mm hub centric spacers up front (3in studs as well) and hub rings all around because the hub size was different on the rims compared to the car (car was 70.5 and rims were 72.3). The spacers are the slide on ones. As for the lug nuts, they aren’t coming loose either. Only think I can think of is the tire being out of round or possibly rims being off balance. Stock rims were 19x9 +45 and I went to 19x9.5 +35, tire size is 255/40 (stock size) and i threw them on the new rims (so it has a slight stretch, but not much). My car only has 20,100 miles and it gets stored away during the winter season as well. Any input would be greatly appreciated.

do you have the correct lug nuts specific to your new wheel style?
Then I d suspect the hub centric rings being correct, take one off and put it over hub and see if there be any play at all. Then same thing with the spacers.
I d assume you already checked and re balanced wheels.
A good machine like a Hunter road force can check each wheel and tire for any "out of round" conditions.

What front hubs are on your car? Is it the 4 bolt hub or a single nut hub?

20 bucks says it’s the tire balance. Have a tire shop (recommend Discount Tires) rebalance them on their finest setting.

Did you run the wheels without the spacers to see if it still shakes?

My money would be on out of balance as well and D/T gets the nod.

That might be the issue. I need to have these road balanced. The shop that did them just balanced them the normal way ( spin em in the air and throw weights where it says to)

It’s 5 bolt hubs but they’re 3in long and the spacer just slides on

I can’t, with our the spacers in the front, the spokes on the rims would hit my front caliper

Not the bolt pattern, how they attach to the car.

I find that hard to believe. Now you're gonna make me look/test-fit, since 6-pots fit fine on 9.5et35

please share make/model of wheel and tire.
Some Chineseium wheels are very badly out of balance and I had to throw 2 new General tires away because their internal defects were such that they would never balance. Had to buy 2 more tires and those were within tolerances.

Oh my bad im assuming it’s gonna be the single nut because there rears have 4 bolts

I have the performance pack and the calipers in the front are too big to fit these without running 15mm spacers

Did you verify the spacers actually sit flush on the brake rotor? The hubs on your car stick out further than any other hubs, unless the hubs are machined down a 15mm spacer may not fit depending on how it is made.

Sorry too hear you are having vibration issues. I'm confident we can help with a solution.

Start small and work your way up "the food chain".

First....Spacers. If they are not hub centric there is a pretty good probability that is where your vibration issue lies. Try running without the spacer. If the spacer is needed, you may need to upgrade to a high quality hub centric spacer.

Second...As mentioned, Have the tires road force balanced. ( Your local Discount Tire store uses Hunter Road Force machines). That will usually solve the issue. If not, the machine will tell you if you have a balance issue or tire issue.

Hope that points you in the right direction.
