I'm probably off base with this idea but what about using snow tires
(without the studs) for the Elan as everyday tires. They use soft rubber
and I found Hankook has sizes for the Elans. I posted their specs here

Your document name is incorrect it's:

As one that has a lot of experience with snow tires; I live in
the Colorado mountains, and drive on them 6-7 months out of the year,
I'll give this one a shot.
The problem with snow tires on dry pavement is the depth of
tread. The tread blocks flex under load which helps them grip in snow,
and also helps them throw out packed snow. Because of the tread flex a
friend describes them as like driving on scrub brushes. There is
easily a 20% drop in traction from reasonable all-seasons. This based
on my subjective feel driving the same dry roads with both types of
tires not empirical data. This is on a large 4wd audi, not a
lotus. Additionally I run 16" wheels with snows in higher profile, and
17" summers so that may add in to the feel and reduced grip.
The real issue is that the large blocks also build up heat
because of the soft compound and flex. This isn't a problem when the
outside air temp is low as they cool quickly and in snow the heat
helps clear the treads. Running them in hot conditions will make them
break down and chuck. They are also quite noisy. So unless they were
shaved down to rational tread depths there by reducing their life to a
few thousand miles, I wouldn't do this.

fwiw: Hankook are pretty good snow tires, I run them on a
Subaru outback and they perform well as snow tires.

Okay scratch that idea. Not many folks here know about snow tires here in
SE Texas. And I thought I copied and pasted that link over.

I just put Yokahama Y379 tires on my Fiat X1/9, size 165-70X13. This
is the same size tire I have on my Elan S4.

Tire rack - $45 each. They are S-speed rated and are year round M&S
tires.

Take a look.
