Hi

What tyre pressures do people use and recommend on a 24kW Tekna?

Im very newbie but what Ive read 40+/-2 PSI

24kw Acenta here - I ran on 42 psi for a year but I got abnormal wear on outer edge of rear tyres (see other thread about abnormal wear) and someone suggested it could be caused by over inflation so I am back on 36 psi now which I believe is the Nissan recommended pressure. I dont see much/any difference in range from this change on my commute though I have not stretched it to the max yet on a very long journey.

Thanks. On my previous cars I have tended to use either the fully laden pressures or go up by about 2 from the manufacturer's recommendation, but the Leaf only has one pressure on the door plate namely 36. I am tempted to run 38 for a while and see how that works out.

I ran 38psi on my 24kWh Tekna and it wore the centre of the front tyres which is a sign of over inflating.

I've dropped it back to Nissan's recommendation now of 36psi.

I also have been looking at the psi readings from LeafSpy and I note that the pressure can increase by 2psi as you drive. Presumably as the wheels heat up the psi increases so I think 36psi when cold is what you should set them to.

Whatever the cause of your tyre tread wear, 38psi was not it!

What other reason would you put forward for wear on the centre of a front tyre? Usually tracking will affect the inside and outside. Over inflating will affect the centre, no?

I suspect different makes of tyres could also be affected differently depending on the compounds used so maybe 38 on one tyre will be ok but not on another?

What other reason

I can't imagine! Unless they were really dodgy tyres. Your extra 2psi would have gone towards reducing the bulge in the sidewalls, that is where the flex is, not the tread.

Goodyear Efficient Grip Performance.... so not dodgy tyres.

It seems to me that over-inflation is usually considered the reason for centre tyre wear. Maybe I was beyond 38, I don't know, but I can't see another reason for it other than over inflation.

Going with manufacturers recommended figure of 36psi seems the sensible thing to do anyway.
