Okay so I was parked and someone hit my car and scratched my front passenger rim up pretty bad so I took it to get powder coated again and was on a spare but then it blew out thankfully it was parked at my house when it decided to blow so the car was on a flat for like 6 days then when I got the rim back and put it on there was a slight vibration coming from it I don't feel it in the steering wheel though I don't know if I'm just being paranoid or what

 

Maybe the wheel is not balanced correctly?

 

There's a chance that your wheel may have had a slight hairline crack from the accident that wasn't caught by the place that repaired and re-finished it. I would double check your wheel thoroughly for any sort of cracks, and make sure its balanced properly.

If everything is good, you might have damage to your suspension from the impact of the car when it hit, and you never felt any difference on the spare, or ignored it thinking it was the spare.

 

Around the last 2 days of the spare it was getting like that but like I said the spare blew up so it must of been vibrating because it was bad

 

Don't be so quick to blame the spare. For all you know, the shaking could have caused the spare to blow up, especially since the issue is still present with the old wheel re-mounted. If the issue was the spare, it would have gone away the second you mounted the wheel back on.

When it comes down to it, unless you have a full size spare, you're not supposed to drive an extended distance on the spare. Its under-sized and much lighter than your other wheels/tires, and therefore puts strain on your suspension and drivetrain components due to the un-even side to side rotational mass. If you were driving long distances to commute for multiple days, along with being hit on that wheel, I would explore the possibility of suspension damage.

 

I wasnt using the car much while on the spare...do you think it could be the wheel bearings and what components of my suspension should I check ?

 

I just checked my tire pressure and it's at 40 psi and all my other tires are at 35 could that cause the vibration?

 

Over inflated tire wont cause a vibration. If anything it will cause a pull to one side, but thats it. As for the suspension components, did you get your car aligned when you had the wheel put back on the car?
