Please don't take offence at the cross post to another site, but with my old fav. Benzsport and now our very own UK forum, I don't know where to post first! <img src="http://www.mbclub.co.uk/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'> Aquaplain/Tread depth post I am wondering when you guys replace your tyres? The legal minimum is 1.6mm, which I have never gone down to. The indicator bar is at 2mm, and when I am nearing this on any section of the tyre I normally have the pair replaced. However, having moved house, I find that my new local territory has many roads which drain very poorly and I have suffered from bad aquaplaining. My fronts are on about 3-3.5mm (4 absolute max), (they got moved to the front from the rear at my last service), am I being wastefull to replace now? What do you guys do?
