1971 3cx2 tyre pressures

[BROOKY]

Hi all does anyone know what tyre pressures for road use i need in a 2 wheel drive 3cx need to drive 8 mile ? thanks

Depends how old and cracked the tyres are

 

[charlie2]

just for roading 28/30 psi if tyres are ok. fronts will need more pressure for working etc.

As Doobin says old cracked tyres are difficult, probably better to go on the higher pressure side as they don't flex like they did when they were young and tend to run hot.
Perfect weather for running old plant on the road at the moment, lots of lovely coolant coming down and a disincentive to get out of the patrol car

8 miles in one of those old 3c's... good luck! Especially if its lived in the hedge for the last 20 years. To be clear, its not the machine breaking down that would worry me - they will go on forever, its keeping it in a straight line!
If the front tyres give up then just hang the back actor out and steer with the brakes

Steering is always wayward normally two turns to the left and one to the right keeps them in a straight line, I hope the brakes are good! I took my old 3D mk2 down the road and found on the level it was ok but going down a hill it struggled to slow down, Good job it had the big 8ft front bucket - that soon stopped it

Lift the front up with bucket, hammer wooden wedge between axle and chassis on the good tyre side, lower down continue as per on 3
Also works on 4x4`s

A 3Cmk1/2 with no front bucket is up there in the list of the worst things to drive on the road

I used to put 30psi rear & about 50 in the front (this was for work on site) but if the fronts look cracked I would only put enough in that these are not flexing hugely as they rotate with the bucket off the ground. If a spare front was on hand off another machine just for the move it might be good. I am thinking of it becoming immobile & blocking the road in an awkward place. Thinking of the risks involved it might be better to get it transported if you have any doubts. A mulitlift wagon can move this rather than a full low loader. Many farmers have low loading trailers now. Are the brakes balanced when pedals locked together - or does it pull off to the side. If you must road it I would do it on a Sun morning or other quiet time!

Reminds me of my grandfather in his 3D, used to watch him come up the road fighting the steering wheel and lighting a cigerite at the same time

That dates it - these days, he'd be on the phone as well!
