My ALTO (VXR-2007) Started to vibrate above 80 km+ speed. Tyre are company standard fitted ones. What should i do to stop bubbling and vibration on higher speeds. ans what Tyre should i use if i go for new Tyres. Please suggest,
First check tread depth if that's ok then go for wheel balancing and rotate the tires. If as you say tires are factory fitted ones it's probably time to get new ones. Go for Yokohamas or any good name brand but make sure to get from a reputed shop and ensure that the tires are relatively new (production wise) and original.
Get the wheels checked, balanced and also check the alignment and the steering rack.
