In the USA, most states that have inspections will fail at 2/32" which is dang close to 1.6mm. From my experience, summer/dry that is fine, heavy rain & winter, at least double that. If you only use it in fair weather, I'd say good to go. If not, now would be a good time to start shopping for new ones.What mm would you change your rear tyres
Both MY rear tyres now between 3.5 and 4 mm but look a lot lower should I wait for them to be about 2 mm before I change ~(UK minimum 1.6 mm).
I take my SLK to mainland Europe 3 or 4 times per year. Most other countries in Europe have a 130km/h limit (83mph-ish) and Germany theoretically allows us to do much higher speed runs although as I tend to drive with the roof down it gets pretty blustery over 200km/h and you definitely can't hear the stereo at that speed so that always slows me down.I'm sure you haven't - after all, the top speed limit here is 70mph! :wink:
(And I believe your 'yet' was a mistype! >)
