what should the correct tyre psi be for 145&155 tyres on a mm1000
thank you

i run 28 front and back, suits me and my driving

thanks, I was told 35psi which i thought was a bit high.

Standard pressures for 5.00/5.20 crossply's was 24 psi. I guess most people run either 28 all round or 28/26psi these days. There is no official figure for 155's because they were never factory fitted, so, just experiment around 24 - 30 psi untill you find a setting that suits your comfort/driving style requirements. 35psi is definately way too high though.....

I use 30/32 psi normally, but do put them up to ~ 36 front and 40 rear if carrying a load.

I've been experimenting a bit, now the snow has gone at long last, and similar to Roy I find a 2psi differential front to back improves things a little I've settled for 28F/30R on really quite narrow treaded Toyo 155s. The difference in the actual contact patch width when compared to the previous Nankings was quite striking given they were the same size tyre

I have been running 155x14s at 24psi all round but I think that the sidewalls have too much flex so when the MM is back on the road I am going to try increasing the pressures a bit.
30psi was about right on my Traveller on 175x13s with two engines, a tool box and other bits and pieces in the back.

A Traveller with two engines? Sounds like fun. Do you have any pictures Mike?

Mike how do you syncronize the throttles

Do both engines drive one axle? or have you got the facility of splitting the drive front/rear?

Thanks folks for your imputs

All right then, three engines, one in the front doing the work and two spares in the back going for a ride

Did you mean 'two engines in the back to maintain traction'?

No, two knackered side valve engines going for rebuild.

Ohh. That's a bit of a let-down.
