Just put some new shoes on the rear. My favoured Yokohama AD08r.

When I checked the old ones that had been removed the tyres were wearing heavily down the centre.

I usually run stock tyre pressures but will be lowering the rear to 30.

Now what about the fronts? I usually run 26 but thinking of dropping it to 24? This is my first set of Yokohama's on the front so haven't got to see wear pattern yet.

Sizes
205/50/15 fronts
225/45/16 rear.

Could it be related to your non stock sizes.

I am running stock sizes and pressures and wear is even.

It could well be. Personally I think I need the extra width. And at £240 a pair I'm not swapping them out now haha.

I have read somewhere that the ad08rs tend to run better at lower pressures. Can't find it though.

How's your tread wear. I should have taken a picture really but there was about a 1mm difference from centre to shoulder.

@dan944 - Rather than wait for the tyre itself to wear and show the contact area perhaps painting a stripe across the width of the tyre with a thin coat of water based paint would do the job. The paint would wear quicker than  the tyre and indicate high/ low or just right pressure.
Just another thought for today.

That sir...is absolute genius.

We do the same for precision engineering but somehow didn't transfer that across to tyres.

Wonderful!!

It's a very long time since I used " Engineer's Blue" but I think my suggestion is a similar principle. "Blue", of course, would be difficult to see against a black tyre.
