Triumph Repair: Front Camber and toe, caster and camber, time howard

Question
My recently purchased 1972 MKIV Spitfire is suffering very poor tyre wear on one of the front tyres. The wear pattern is typical of too much camber, and the hub was found to have slight play when inspected. To make things worse, the tyre is different to the others!
I have provisionally tried to measure and calculate the camber and was surprised to find that instead of a positive 2deg to 4deg, it was actually 1deg. Using the same method, the "good" side shows no camber at all.
I plan to replace both front tyres, and attend to the hub issue. Can you please advise what to do about the camber, and in addition comment if positive will cause the tyres to wear on the outside.
Many thanks in advance!

Hi Paul,
It will be hard to pinpoint a tire wear problem when two different types of tires are on the front. Zero and one degree positive camber on the front will not show up as any tire wear. However, too much toe in and different kinds of tires will do that because the compounds and tread designs being different will fight each other and the winning tire will track true and drag the other one over to scrub off it's outside tread. Plus some tread designs will walk to one side or the other and with two different tires one will always overcome the other even if the toe-in was correct. You didn't say what the caster was. If caster is off on one side you will have to steer to one side and that alone may in time show up as tire wear.

If it were mine, I would just put two tires on and set the toe-in and check caster and camber and not try to figure out why two different kinds of tires with good camber setting and unknown caster is wearing tires. It would be a waste of time.
