So she can afford a new wheel, but doesn't want to buy one as it will "ruin the originality",
If they can build an original spitfire from just a bulkhead they find in France,
Then replacing a wheel, isn't a problem, unless she's, an oof'er that only use's original parts.
Originality is very important to her, she is going to get a new wheel made I think but she wants the old one to still hold air so the car can be driven on it. It sometimes goes up a hill climb at speed, other times it's just a gentle drive to show the car to the crowd, for those gentle runs she would like the original wheel on the car add the car is currently still unmodified from when it was raced in the 60's.
I haven't tried the minefield that is google yet, I was hoping someone on here would know if it is even possible to seal a porous wheel, a full permanent repair isn't possible as the wheel is porous all over. If the answer is it can't run on it then that's fine, but she would still like to have it sat on display for the weekend without it going flat as that looks bad. I doubt they make a tube wide enough
It isn't an area I have any expertise in, I do think it's a lost cause, but she would like to know for sure.
