Hello mate as with alot of thinks that are new, your tyres will need a good few 100 miles on them to bed in, settle down to your car and driving style, this in my experiance is a commen problem, stick it out and drive steady and all should be fine.
I have used TOYO tyres for about 6 years and never had 1 problem ever !! i currently have the new F4 series on my Cupra R and as with all TOYO tyres they are fantastic,
