Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I've read a lot about the different features and what to look for in snowblowers, and this site I've found is a great source of information.

One variable that I haven't found much info on is tire size.  I've seen different models with 4.8 inch wheels that look narrow and high, and I've seen other models with 6+ inch wheels that look a little shorter and wider obviously.  Is the narrow designed to do or perform differently than the wider wheel? Is this really a worthwhile consideration, or should this be the least of my concerns? Thanks.
