Hi Pete;
I'm not sure if this helps, but I fitted TR6-type painted wire wheels to my
TR3A that was built in October 1957. I don't know what the offset of the
wheels are, but I think they are 5.5-inches wide, as per original TR6.
I did a load of research on tyre sizes at the time. Interestingly, I found
the greatest volume of information from the Australian TR Register guys.
Anyway, I ended up fitting 195/65-15 tyres, which I believe may have been
an original fitment to some TR6's (sorry if I'm wrong, TR6 guys). On my car,
there is no tyre interference even over bumps, except that on absolute
full turn there's a little bit of rub. It's no problem, though. The results of
my extensive research showed that, when fitting wider-than-standard tyres
to sidescreen TR's, it's a case of luck of the draw because no two cars are
built exactly the same. Some guys have a bit of interference with this
size, but most do not. I even had an e-mail from a TR3A racer in Australia who
has 205/60-15's on his road car (no suspension modifications) and he has
no interference problems. I did communicate with some other guys who had
attempted to fit the same size tyre, though, and had some problems. The
favourite seemed to be the 195/65-15's, however, if you really want the
maximum
amount of rubber on the road (as I did), with the minimum risk of
interference.
I hope that helps and I'm sorry I can't give any solid information on
offset, etc.
