On my optimisation report it gives the tread depths as 5mm inner, 7mm centre and 5mm outer. Does that sound right?.
I haven't had much experience with these runflats but does the tread depth vary across the width of the tyre?.

Cheers.

Starting to get a complex here boys.

I thought that they only started with 6mm? I going to have to have a look at my report now....

A quick visual check suggested that the inner tread certainly looks deeper than the outer treads.

Does anyone know what depth the tread(s) should be when the tyres are brand new?

Got confirmation from the GT-R tech. The original trad depth is 9mm centre and 7mm inner outer so all fine.

At 6k miles all mine were 7mm (centre I assume).

Very good to know, thanks for the information!

That suggests you'll be through a set of tyres in around another 5,000 miles doesn't it? A bit worrying if right mate.

Optimisation thread depths (2500 miles) 3,5,4 :nervous: at this rate they won't even make 6K

 

[WoREoD]

What optimisation was that? Mine was at 1200 with a service at 6000......

At 7500 all tyres are 6mm and that includes a few laps of the 'Ring and a day at Millbrook. Clearly I dont try hard enough ;-)

 

[apj30]

Mine are 6mm in the centre at 1500 miles which seems pretty average.

Amazed that someone can still be at 7mm at 6000 miles, does this mean the rest of us have really been thrashing it?

 

[mrvisser]

It was meant to be a 1200 service but my hpc was booked for weeks. The 2500 miles is almost all A and B roads so I'm sure you can get more miles out of the dunlops. And a better mpg than mine...
