Rear tyre preasure on trike

[Tom Rae]

I have been running my Pembleton rear tyre at 20 psi however it does tram line and on recommendation from another trike user I upped this to 30lbs psi and now it skips and skids more easily! What pressure do others run theirs at? Mine is a 2CV wheel fitted with a 135 x 15 tyre (Fyrestone F560) with plenty tread on standard 2CV swing arm. Experiences sought please.

Original Morgans would run 18-19psi in the front wheels, and 27-29psi in the rear one. This is taken from a Morgan trike Forum;

Experiment with pressures;

At the front. Pressure too low = heavy steering. Pressure too high = bouncy uncomfortable ride.
At the rear. Pressure too low = strange effect like the rear’s trying to steer. Pressure too high = wheel will skip over bumps. Rear may slide out on larger bumps.

Cheers Geoff. My fronts are fine at 20 for the rear it looks like mid way of 25 looks worth a try.

On my 223 Lomax I have approx 18 to 20 psi on the front and 28 to 30 psi on the rear with 135 tyres.
I look at the shape of the tyre on the road to determine the pressure.

On my Lomax 223 I ran the rear wheel on 35psi, cured the tramlining and also reflects my BSA three wheeler days when I ran the rear wheel on 40psi,
although this was a cross ply tyre.
