Haida HD919 135/50 R18 Ford August 25, 2014
Haida are the worst tires I have ever used. These Chinese made tires should never ever be allowed into western countries.

They are unstable at speed, noisy as all hell and absolutely not grip in the wet and almost no grip in the dry.

If you have a death wish then buy Haida Chinese tires otherwise look elsewhere.

The people who make and those who sell them should all be thrown into jail.

I had them on my car for about 2 months now have taken them off and traight into the rubbish tip where they belong.

Keep your family safe, dont buy chinese tires.
