Summer tires vibrating at over 110 kph

[canadien99]

Hi,

I recently (a couple of months ago) changed from winter tire to summer tire.

It never happened with the winter tire.

And when accelerating above 110 kph and upwards, the car starts to vibrate. It vibrates even more intensely for example when the speed drops for example from 120 kph to 110 kph, and the vibration lessens a little bit once i press the gas pedal.

I read several posts about balancing, warped tires, etc etc, but based on a little bit more description that i've provided, does it help to isolate where the problem might be, or am i missing some info that i can provide.

i'm really at a lost.

Thanks in advance.

alignment could play a factor, did u have problems with ur winter tires/rims?

if not, check the tire pressure of all 4 tires since it had been sitting there.
if not, check for damage/flatspots of the tires
if not, balance the tires/rims.

To me it sounds like one or more of your tires are not balanced.

As for alignment, you can easily see your tire tread and see if it's even all across.

You need wheel/tire balancing. Let us know how it goes
