TONY - There's some REALLY poor imported brands of tires on the market today. I wouldn't stray too far away from name brands. The less common brands sell on price alone, and to reduce cost they leave out the rubber components that protect the rubber from rapid aging from sunlight, ozone, etc. I've heard of full size tractor tires cracking and weather checking in one year. Even the new Firestone's are made off-shore, not sure how they will eventually hold up, they may be O-K, or not much different than the cheaper imported brands. We'll all let your know in 40 years!
For pushing snow, turf tires with chains are best, but I actually prefer lug tires for mowing. My yard is really pretty flat, but I have a ditch and bank along the road, and if you ever make a turn uphill, the turf tires will spin and tear up your grass, while a lugged tire grips well, doesn't spin, and does NO damage.
