Seem to be going in circles on this topic.😀😁😂

[Bigron]

I am STILL unclear as to whether the tyre or the wheel itself is the problem; could you please elucidate?
If it's the tyre and to a lesser extent the wheel, may I suggest a liquid rubber compound called OKO: I have had great success with this in the past. Viscous yellow fluid which sticks like shit to a blanket and seals/hardens at any leak site when exposed to air.

I put a tube in my wheel barrow tubeless tyre. Is that OK?

Do you race your wheel barrow?

Or take it on the motorway ?

If it's got wheels, you can race it!

As for my issue, it is the wheel that is porous, tyre is fine and the rim is fine and the bead seals.
Car is the blue one in the link below

Used to belong to Patsy Burt and is the only one left of those that Bruce Mclaren built, hence the desire to keep it original.

I'm assuming this is a magnesium wheel.

Car type, wheel type might help.

[al brown]

Yes, I think it's a magnesium wheel. It's a Mclaren M3A, one of only 3 built and the only one surviving, one is unknown, one is in parts in Australia or New Zealand they think.
Other than that I don't know exactly what wheel is fitted, other than it is what came with the car when it was sold after Patty's death and is what it was displayed with when it was loaned to a museum after she retired.

There is a company in Slough called Ultraseal which can vac impregnate mag alloys with a resin to address the porosity issue.

A bigger concern is the structural state of them (and the others) as they are not know for their long term durability (but would be fine for display etc) so a structural test would be advised.

[al brown]

Cheers, I will look them up. The wheels racing days are clearly over and I guess the others are not far behind add they are all the same age. Putting 350 HP through a weakened wheel isn't the best plan.
I think they are all off for an X-ray, I know the leaky one has already been. I think the issue is getting a company to stop it leaking is hard as they will assume it will be driven in anger so won't want to take liability.
Maybe time to admit defeat and just replace it, however she is still refusing to use an electric fuel pump to get her alpha Romeo around and is still using the 1920's vacuum feed, with all the problems that generates with modern fuel.
Like she says though, cars are only original once and when you start changing them, where do you stop.

[Doctor Gollum]

Which approach is best? Keep it clean and in a museum display or keep it road ready and able to be seen, appreciated and used in a manner more befitting a car of that pedigree?

Age old dilema that... and rare that the two paths are not mutually exclusive.

[Sir Tigger KC]

Sounds like your friend needs two sets of wheels, a good set for driving and the originals for display purposes. 

[al brown]

She has many more cars than just that one and they all get to go out and play. She isn't one for locking them away so no-one else can see them.
As she puts it they are only hers for now, someone else will own then when she's gone and it would be unfair to hide them from people who would like to see them. She let's her gardener borrow her e-type!
I will look into getting the wheel in with ultraseal, so at least it can be presented in its original condition and she can sort getting some replacements made for when she runs it in anger.
Thanks for the info
