Will this not be classed as over pressure slightly and thus wear the centre of the tyre down quicker????


Note that its at speed though which does increase tyre loading slightly anyway.....would not recommend these for round town because i have not tried them in that scernario!

Certainly, the tyres are wearing evenly though...

Should have also added that the readings are taken with a quality PCL tyre gauge!

I normally put 32psi all round (just habbit I suppose)

When I do use the car, I nip arround the village a bit but allways tend to take it for a bit of a run.

Am tempted to put mine up to 36psi all round.  Last time out I nipped to Mablethorpe on the Motorway returning 30 @ 50mph ave in fog and 32 @ 72 ave  coming back in a 3.0 so cant se why 35/37 mpg couldnt be achieved if I actually did 70mph  ;D ;D ;D ;D

Mine are normally done by my mate at his local garage, the day before I went to Mable thorpe I used one of those auto display ones at Morrisons and 32psi all round.

Old tyre pressures were 31 and 33 on the rears, and the fronts had dropped to 26 and 29 since last checked by my mate about 8 weeks.  only used the car twice in that time.

Will use the auto one again next weekend to see if there is a drop in psi over 2 weeks

Also found I had a wheel vibration at *5 Mph which needs sorting

On the MV6, I tried some experiments about 2 yrs ago, and ended up 32f 35r

This provided best compromise of handling/mpg and tyre wear (rears were doing edges).

I tried increasing front, but it made the awful understeer that the MV6 seems to have even worse  (not sure why MV6 shows understeer tendency, suspect its to do with the less than perfect wheels)


Tractor runs 32 all round, must more, and it makes it a bit 'skittish' in the wet.

I went over to visit JasonH on the weekend and he was saying then that all Omegas seem to be running too low pressure on the back judging by tyre wear.

Mark's figure which is about half way between laden and unladen even without his exhaustive testing does seem like a good figure to use.

nearly all the petrol stations in my area do free air and water
then go and charge about £1 for 5mins to use the hoover right nest to the air and water machine

I guess tho......that a 4pot would be better with less than 36psi on the front....less weight  :-/

I put 30psi in the front......most of my driving is plodding around town....i usually have av speed according to the comp of 19mph.

I did try putting 38psi in the back once (when i had a slow puncture) and boy was the ride harder.....i could feel the bumps more even sitting in the front! Back down to 33psi now.
