Tyre Pressures for Track
Discussion
Have a search through the old threads. Micknal always suggested using the same cold tyre pressures on road and track.
From memory this was 30 PSI front, and 18 PSI rear for the GTO-3, but do go and check that as:
a) I might have the figures wrong, and
b) These figures might not apply to the M400.
You can't really control the hot pressures as these vary greatly due to the heat.

I thought it was 20 psi front and 30 psi back for road and track.
My 3R uses the same wheels so I assume this would be the same for the M400
On a car limits day with Andy Walsh, he suggested putting in an extra 3-6 psi per tyre to give a better cornering grip and to reduce tyre wear, especially around the edges of the tyre wall.

When I picked my car up (3R)last week I was told 18 front and 26 rear.
Thats what the handbook used to read, then it was changed to 18F 28R
but has now been upped to 20F 30R
think it makes little difference on road and just affects tyre wear on track.
20-22F and 30-33R is a good bet IMO.
For me on the M400 I've now use 20 psi front and 30 psi rear.
I used to set them to 18/27 until someone pointed me to the *correct* manual.
On track do a few laps (and optionally wait for the handing to go off) then lower the tyre pressures back down to 20 and 30 again. I did this at Cadwell Park recently and was very surprised how far off the handling had gone - rears had gone up by about 6 psi, fonts by 3 psi. After readjustment handling was back to what I was used to.

O.K Thanks guys. I'll start will the factory settings and take it from there.
As someone who currently races a motorsport elise (ie. another mid-engined car) I still think 10PSI difference between the fronts and rears is an awful lot! I am not sure what that says about the balance of the car. Presumably the implication is if you had mathing pressures front to rear the car would oversteer in a big way!
With the fronts being so soft how do you find they wear on track?

M400: 20(f), 30(r)
All other M12 models: 18(f), 27(r)
Factory recommend maintaining the above pressures for M12/M400 for both track and road use.

Thanks Simon. There seems to be a lot of confusion about this.
When I bought my 3R, the dealer crossed out the 18 and 27 in the handbook and wrote in 20F 30R. So thats what I have been running.
I was informed that the factory had revised these pressures and that the handbook was incorrect!!
Sure there is not going to be a massive difference between 27 and 30 (especially with my driving skills) but it would be good to have a unanimous figure that all dealers recognised too!

The handling/roadholding/ride of M12s and M400s is immensely sensitive to tyre pressures; just a couple of PSI can make a significant difference to the way in which the car behaves. The pressures I've posted are the result of extensive testing and will optimise your car's dynamic performance.
