So I spent about $4500 on wheels and tires and my car rides way worse than it did with OEM wheels. When I get to about 80-85 I get a good amount of vibration. What can I do to get rid of it?

 

be more specific. What size wheels and what is your tire size? Your ride will get harsher if you have lower profiles. If you have 20's then deff. you will feel a difference. Do you have spacers? How does it feel like? is it just vibration or is your steering wheels going left to right? You might have a bad balance on the wheels and tires. Is the vibration there when you brake? If so it could be that you need an alighnment. I hope you did get one after you changed out your wheels.

 

i had the same problem...anythin under 70 mphs it was smooth...than over that it was bumpy as hell...get an alignment...if u still havin problems...idk wut to tell u

 

Same problem here, just got new rims/tires. Get some Hubcentric rings and an alignment and it will be smooth again.

 

get an alignment

 

245/35/19 front and 275/35/19 rear. Staggered with, I believe 7mm spacers so they would clear my Brembos with Rotora rotors. I thought alignment only was if it pulled left or right. No problems there. And not when I brake.

Some guy was saying something about getting my tires trued? I guess they spin them and nock off and small bumps or imperfections in the tire. Anybody know about that?

 

Like others have said, sounds like you just need some hubcentric rings. They work wonders.
