i have a 04 G35 coupe 6mt... just had tires replaced wit nitto invo on stock 18s.... after having the tires replaced there is a noise from the tires 20+mph, as we goto 40 to highway speed about 65-70.... the noise is unbearable and alot of rumbling vibration.... i had an alignment done also because i thought that was the problem... after that still no good... i tried different amount of air pressure in the tires 26,32,35,38psi... no change at all... it seems to be coming from both the front tires... i'm not sure about the back... on highway it gets to the point where my speedometer and my fuel guage would start to vibrate and bounce alittle.... when i turn OR change lane, the noises and vibration gets worst....
definitely want to kno if its the tire or something else because i check the wheel bearings and bushings around the suspension and they were all good (pa state inspector btw) so all i can think of is... nitto says i need to goto a authorized dealer to get it checked out... but other than that, any input? thnx

 

Having read your thread several times I not sure the issue is your tires. Have an independent alignment shop check out your alignment along with the tire balance. New tires....you shouldn't be feeling a vibration at any speed. Sounds like you have poor quality mechanics doing both your alignment and balance!

I must say its ur tires,,, u should talk to the people from where u got them and get diff ones

 

your rotors might be warped or they didnt balance your wheels correctly.

 

Are your steering wheel vibrating or shaking?

Could be bent wheels, wheels need balancing or your lugs are loose and needs to be re-torqued.

 

really its the whole car thats vibrating.... not really just the steering wheel... i did retorque the lugs and checked for everything.... when i looked at the treads the one strip near the inside seem to be just a tad bit taller then the treads on the ouside... i'm not exactly sure if thats what is causing it...
i'll check to see if its the alignment or the balancing....

 

^ although im PRETTY SURE its not your tires
switch out tires with another person to confirm the problem isnt the tires.

feathering shouldnt cause the whole car to vibrate.

check the rims

 

next week imma have NTB lookk at them bcause they are authorized dealers of NITTO
