Hi, my coupe vibrates as it approaches 50mph in 4th gear but it doesn't vibrate past 70 ie on the motorway....Help, thanks

get the wheel balance checked (its possible one has come off)

also look at the tyres for any blebs or bulges (check the inside tyre wall that you cant normally see too)

Great thanks! I know they are new tyres (500 miles) so maybe a weight has come off. I'll pop it in to tyre shop...
