4 snow tires on my `85 big red?

[dynodave]

The-specs-say-that-these-tires-are-for-use-on-high-fender-machines-due-to-the-fact-that-they-"expand"-up-to-40%-under-heavy-throttle.

So-my-question-is,-has-anyone-used-these-on-a-`85-250ES?
What-size?

Will-they-hit-the-fenders-with-my-fat-a..-on-it?

Thanks.
