Since I change my new Michelin PP2 i used to wash it weekly; however it doesn't looks new anymore and the surface had turn a bit of yellowish donno due to what reason. One day i asked my neighbour on what type of tire wax he used for his cars (his car tires was real shinny) and he recommend me this tire wax.
So i bought a bottle of Waxco Auto Guard Protectant from Tesco for RM13.90 yesterday and spray on my tires this morning.
Waxco four in one (rubber, plastic, vinyls and leather)
This is the end result (like brand new again)
