husqvarna TS 354 tire question.

[lukdiver]

I'm using factory tires/wheels (23" x 10.50"-12) and wondering whether I can get by 22" tires? I'm using snowchains on original tires and looking at getting another set of tires so I can avoid the hassle of chaining up every winter when I go to the snowblade. Thanks for replies.
