Last week on the 10th of May 2013 I got new tyres for my PKDM alto. Yokohama S-707 (165 r12). Now the problem is that when i drive my car a sound is produced by the car as if the bearings are at fault and the sound increases with the increase in speed. Got my car fully inspected fro Suzuki 3S dealership and they have passed the vehicle by all means. So what should I do. The person from whom I bought the tyres said k aap kal ajayen mein ap ki gari jack pe charha k chala k dekha dunga tyres bilkul thek hain. Am wooried please guide me that what should be done as i am a completely inexperienced.
