Parallel import sports/prestige tyres... Nothing wrong with product, just don't have manufacturer warranty.

An example from this week... Maserati 4200.... Michelin PS3..... Authorised Michelin seller... $1750 set.... Bob Jane $1075, Inc fit and balance plus a $100 fuel voucher!

It's possible the grey import tyres are meant for different market/climate.... But hard to know or tell......
