I use 30 psi all around with radial tires.  The original tires were
typically bias-ply, and 20/25 seems a bit low to me, too, especially for
bias-ply.

Well, at the risk of starting a never-ending thread, what's the consensus on
tire pressure for my BJ8?  I will be doing mostly local driving, certainly
not racing (!), and will be setting them cold.  The book says 20/25, which
seems low to me.

I bought a set of 60 spoke wires from Hendrix , tires shaved and all balanced. He tagged my tires 30 psi drivers side , 28 passenger side , my ride is great with no problems

Hi Mike,

You don't say that you installed different sized tires from the
original so I'm assuming original.  These tires aren't much different
from those on VW Beetles in size.  I wouldn't start with lower
pressure in front than rear in a Healey.  That is what they did with
swing axle rear engined VWs to counter their tail heavy oversteer.
Healey weight distribution and suspension is very different.

So 25/25 if you want to run pressures that low.  I'd personally start
at 30/30 and go from there, observing and experimenting to find what
you like.  Higher pressure will mean easier steering to some extent,
and if you drive on curvy roads like I do you don't want to wear out
the outside edges of the tread before the center is worn.  I am sure
that there are other folks with more and better ideas.

I agree with Steve.
As an original owner of a 1967 BJ8 I have some experience with tire
pressure.
It is worth experimenting with 128 and 132.
With  my car the handling difference is noticeable in mountain driving.
Don't like my wife driving at 128!

The correct tire pressure will vary widely from car to car, depending on tire type and static weight distribution.

The correct method for determining proper tire pressure is as follows:

1. Use a soft white chalk to mark several vertical stripes across the tread and sidewall of each tire;
2. Drive the car hard, including tight turns;
3. Check the chalk marks. The marks should end at the knuckle where the tread and sidewall meet. Some tires have small triangles or arrows to mark the knuckle.
4. If the chalk remains on the tread, the pressure is too high. You are not using all of the tire. 
Chalk ends below knuckle, tire pressure is too low. The tire is rolling over too much.

Best regards,
Jim

These days tire pressures are generally much higher than they used to 
be, also for radial tires.
In the 60's-70's advised tire pressures for radial tires were much less 
than today, 1,8-25psi was quite normal. These days however tire 
pressures are nearly always higher than 28psi and sometimes as high as 
45+ psi, depending on speed and load. I am not sure if this is caused by 
the use of different materials/techniques or different insight but also 
consider that modern cars are heavier.
For relatively light cars like a AH 30psi is perfect as a basis to 
start, than just lower or raise the pressure with small amounts to find 
the optimum. For reasonably light steering keep a minimum of 30psi in 
the front tires, especially if you have wider section tires. There is no 
sense to go beyond 40psi.
It is a question of ride comfort, steering effort and road holding 
(understeer and oversteer) so play around with different pressures in 
the front and the rear until you have found what works for you.
In most cars I use 30psi in the front and up to 45psi in the rear, 
depending on the load and expected speed en route.

Likewise, you can use a tire depth gauge.  This will take more time but over 
time it can indicate problems other than tire pressure.  Measure the depth 
at the inner edge of the tire, the center of the tire, and the outer edge of 
the tire.  If checked every six or so months, even wear over the width of 
the tread would indicate a pressure that is providing full tread contact 
(9-9-9).  If wear is greater at the edges, tire pressure is too low (7-9-7). 
If wear is greater in the center, pressure it too high (9-7-9).  If one edge 
is wearing more than the other, wheel alignment could be a problem (7-9-9 or 
9-9-7).

If you need an excuse to  go out and drive the car hard periodically, the 
chalk method will be your first and best choice.  The depth gauge method 
will make you check your tire pressure and wear close-up more often so I 
recommend you do that, also.

While you are down there, check the date on the tires and the condition of 
the sidewalls.  If you are getting depth readings at or below the threes or 
they are over 7 - 10 years old, you are overdue for new ones.

This works fairly well on cross-ply tires, but on normal radial tires it 
only works when pressures are really way out.
It will however work for discovering front wheel misalignment for both 
types of tire.

While measuring tire wear may give historically accurate information we
really want to get it right before the tire wears unevenly.

Consider doing what is recommended at:

http://www.fluke.com/fluke/uses/comunidad/fluke-news-plus/articlecategories/automotive/racetracktemp

Admittedly much of what the site touts is not relevant to street driving
but you can get the information you need to adjust tire pressures in real
time.  And while a contact probe may be most accurate I use an infrared
pyrometer to tell me whether tire temps are increasing too much or not
enough, etc. etc.

I wish I drove my car enough to matter. I am more concerned about the age
of the tires and sidewall failure than uneven tire wear :)
That said , my car is a bit bumpy since I put the new tires on it. I think
the shop over inflated them. I need to check on them.
