Different wheels in front and rear. example: 245/45/17 front wheels and 225/50/17 rear.
cause of this is the different spinning of the front and rear wheels. as u know all quattros have to get same tires on all rims. maybe i helped someone. (had this on my A8 shake hard at 60km/h)u can seriously damage your car driving like that. check your tires MUST be the same size.
It would be highly unlikely.
The symptom would indicate a wheel/tire/balance problem. You need to have a professional inspect if you are driving at those speeds. also make sure if you drive at 120+ mph, you have "Z" rated tires for safety.
My guess would be wheel balance.
128 mph
150 mph
380 MPH
i would really like to know myself
about 160 mph
196.97 mph
No,-The Audi R8 4.2 FSI accelerates from 0 to 60 mph in 4.4 seconds and has a top speed of 187 mph-The Audi R8 5.2 FSI accelerates from 0 to 60 mph in 3.7 seconds and has atop speed of 196 mph-The Bugatti Veyron 16.4 accelerates from 0 to 60 mph in 2.489 seconds and has a top speed of 252.9 mph. This is the fastest production vehicle to date.
If it happens when you are driving fast (60-70 MPH) it could be that your wheels are out of alignment.
Can be a bent wheel, tire out of balance, or worn suspension parts.
