So recently my steering wheel starts to shake and I feel my gas pedal vibrate when driving approx. 60mph and up. The faster after 60 I go the more pronounced it is. I checked the Tire pressures and outer sidewalls...there were no bubbles, and pressure was 30PSI, I increased it to 32 and there's no change. Also the TPMS light turned on for a day and now it shut off...but the problem is still there. Any ideas?

My car is not lowered
08 coupe 6mt

It's sitting on 20" Vertini magic blacks with Hankook Ventus v12 evo K110 with less than 2000 miles on them.

Someone please gimme some help

 

Get your wheels balanced at a shop that knows what they're doing

 

^ what he said, get your tires balance and rotated just for good measure. There is definitely a problem with your tires....

 

Rebalancing would be your first step. Hopefully that fixes the problem. Don't go back to the place you went last time though. Hit up a different shop.

 

Beside the usual check,Check your tpms for any leaks, had one in the d/s rear.
It was loosing aire from the sensor.

 

You could also try just removing your wheels and reinstalling them. You could have some trash stuck in there. Guys working at tire shops aren't known for being detail oriented. Also, if they used an impact wrench to run up the nuts, they're very likely not on flush, and overtorqued. All of that can cause you problems, especially if you heat them up (alot of braking) because you can deform the rotors and wheels. You'd basically be stressing them, then heat treating them.

 

Thanks for all the replies guys. The shop I went to was pretty reputable, they mounted and balanced the wheels in front of my eyes and mounted em and the car drove beautifully when I first rode it around; better than my oem rims and tires so I was really pleased. I'm going to try to take them off and remount them and see if that does anything, if not it's back to a shop to balance em.

 

Did you hit any hard dips or potholes? Your alignment could be messed up

 

Do the vertini magic require hubcentric rings?

 

Doggy - haven't hit anything too hard. I know about a month ago I might have hit a pot-hole and felt it thinking it might have caused a bubble, but there was nothing significant afterwards..meaning for the next month until this issue popped up a few days ago

cereal - nah they don't require hubcentric rings, the wheels were on for about 2000 miles running smoothly before they started to become shaky just recently

 

Definitely get it balanced first. Supposedly should be done every 6000 miles anyway. it's strange it's just occurring. Had to get mine balanced today and that resolved my issue. Alignment is if it's pulling to the right or left.

 

Thanks Cereal, I was going to try and take the wheels off and check them today and put em back on, but it rained and I got lazy. I think I'll go get them balanced tomorrow and see how that turns out before I go get an alignment done. If you don't mind me asking, how much did you pay to get em balanced? Any idea on what I should expect to pay for an alignment also?

thanks bro

 

20 per wheel... from tire chain shops (discount tire did mine). Another place was 10 per wheel where I am but their machine was down. Alignment varies..if your dealer does it it's around 85. But it can be done for less.

 

Finally got around to getting em balanced...took it to the place that put the wheels on and to my surprise, there's actually a small BEND in the driver's side front wheel that's been causing this vibration. I cant believe that small pot-hole I hit a month ago caused this ****. Now I've got to find a place to fix the bend!

 

Go to Americas tires and get them balanced there.. i had the same problem when i put my 20's on i got them balanced at a tire shop that charges a bit cheaper but something new i learned were that in some wheels they require weights in both sides of the inside of the wheel. i dont know if you understand but sometimes they just put a strip of weights where the balancer tell them to. but they dont check again to see if they need some in other areas of the wheel. Oh and check to see if you need hubcentric rings!
