Ariens Snowblower ST924 tire repair

If tubeless (likely is), it'd be noted on the sidewall... 
 
The valve installed, in the rim, is just like an automobile, (tight in the rim).
 
I would find the leak first (soapy water sprayed on it), see if repairable, bead leaking, etc.
If the bead is leaking, I use clear silicone on the bead after cleaning the rim and tire-works great..
 
But yes, a tube would work fine as a fix.
