Im not a fan of 'bling' tyre shine, Ive used AF Revive which isn't a dedicated product but it looked ok. However, i keep hearing people rave about, Espuma RD50 on DW
Here is a quick snap, it looks a little wetter in the photo, than it does in the flesh - lets see how it performs over the next few weeks, bear in mind i live up a muddy track.
Note: this is on a Nokian Winter Tyre & some folks on DW are finding it works/looks differently on different makes of tyre
