I bought a Metzeler front tyre for a bargain price of $80. This company were having a sale and had to get rid of stock. After fitment of the tyre, my front end shook like mad. Deluxe's ride like a magic carpet FFS, so what's up here? Rang the bloke who fit it, "yeah mate" we balanced it......Bullshit!!! Anyhow, long story short, I took it to Frasers, they told me it was 110 grams out!! WTF!!! Anyway after balancing it was a little better, but still not perfect. I am replacing both tyres this arvo with stock Dunlops. Work well for the way I ride. The point is, if your front tyre is not balanced, you WILL feel a vibration...
