I've had a set of Michelin tyres on for 12 months and have checked tyre wear. The centres have worn 2mm but the outer edges only 0.8 to 1mm. I have a digital depth gauge, that's why I'm going to .0 of mm.
Should wear be more on the centre? My car is a 1.9TDi with 205/55 16 tyres which are always kept at 2.3 bar or 34psi as specified by Audi. This is always set cold first thing in a morning when I check pressure. My gauge is accurate too.
Does anyone elses wear more in the middle? Any thoughts appreciated.
