I have a 2009 Arctic Cat 500 4 wheeler and want to upgrade my tires. I think I have narrowed it down to swamp lites based on what I do. I stopped into the local shop and they want $650 for a set of 4 mounted on my current rims. I went on line and see them for sale from $75 to $98 in many places, plus shipping. I was wondering what folks experiences are in getting tires for their ATVs. Would you buy on line or local, and why? Any recommended shops in Alaska or on line? Thanks for your input.
