Tyre pressure?

Post by ghostmadlittlemiss »

I'm the proud owner of a 1967 Morris Minor. Unfortunately, she didn't come with much in the way of an owner's manual and the tyres are looking a bit low. What's the correct tyre pressure? Thanks in advance.

If I remember correctly it is 22 psi all around with just 2 passengers or 24 psi all around with a full load.

Don't forget the spare!!!

There is a free manual you can download. I'm sure someone will post the link as I can't remember it right now

Ok, now I'm really confused. When I went to fill them up earlier, it said they were already at 25 psi. :o They look low but the steering feels fine so I think I'll leave them for now. Thanks for your help.

If they are radials then the side walls are softer than cross plies and they will look squiggy. I run mine on 24psi all round which suits my driving style.

And I run my 155 tyres at 30 psi - rears go higher if load to be carried. PM sent with manual download.

30 psi is likely to give you wear in the tread centres, however if you do more heavy corners than straight miles, you're less likely to notice.
With 155's mine have felt poor with 30psi and 26 to 28 has been a little better. With 145's 24 to 26 should be fine.
22 was the dealer recommendation... and yes they will look a bit flat with that.

So with 165's 30 psi should be about right?

Yeah I know, I replaced the tyes with what was on there before I got the car ... when the 165's wear out I will be going with 145, they drive a lot better.

165s are rather too wide for standard wheels. The 8cwt van has 165s on wide wheels.
I would have thought that with wider tyres then a lower pressure is needed? Discuss

Any 'dealer recommendation' for tyre pressure would be for 5.20 x 14 crossply tyres - very different beasts to radials!
The answer really is - use what suits you best. After a long run (dry weather!) - feel the tyre treads and side walls - if they are hot (expect warm) then the pressures are a bit too low - pump them up another 2 psi. Also pump up the rears an extra 4 psi if carrying passengers and/or heavy boot load.

If the back end of the car has a tendancy to overtake the front on roundabouts in the wet then possibly the pressures are too high.

Wrong again - radials were available as an option from the dealers.
