Uneven wear on tyres

[Calimagg]

Just back from dealers for roof foil and EGR clean, they also checked tyres, see attached.
Any idea as to why the NSR and OSR are so different? Pressures checked on a monthly basis.
Time for new tyres, but should I be getting anything else checked?

Uneven wear is usually down to 2 things....tyre pressures, tracking.

It might be a good idea to have your tracking checked before you fit new tyres. Some tyre centres will check tracking for free.

I agree, that wear is down to miss aligned tracking. A laser aligned 4 wheel track adjustment is needed.

Costs about £79 but well worth it if it saves you a set of early tyre replacement.

Just tried to have my 4 wheel alignment done on my California It was a hunter wheel alignment centre near me, All was going well untill he asked if I had adaptive cruise control, when I replied yes, he stated that he couldn't do the alignment, as the Adaptive Cruise Control and emergency...

To me it's only the NSR values that suggest tracking. The remainder is just under inflation, with the wear taking place on the edges. More pressure pushes the centres out and will even up the wear, although I think edge wear in inevitable with the weight of our vans and the scrubbing during cornering.
I always run my tyres at the 'fully loaded' figure given on the door label. But my teeth are falling out as a result, and they are more expensive than tyres.
