Lawn tire options

[Cord]

Need to pull the trigger on some replacement tires for my Toro 3500 http://www.publicsurplus.com/sms/docviewer/aucdoc/IMG_3543.JPG?auc=954898&docid=7754511. Stock front tire is a 20x12-10. This is an oddball size so I'm having the rims narrowed so I can fit a 20x11-10 tire. Goal is to get good forward and sidehill traction without ripping the turf when making tight turns. This is a rear steer machine and when cranked to the stop it will get the front tire to a 12" turning circle. With this wide of a tire it will skid and I'm worried about tearing the turf. However I also want traction so it's a careful balance between turf damage and traction. Already looked at the chains option and they won't clear.

My short list (in order of price)
Golf Cart | Nebraska Tire (with this many knobs I'm not sure how much bite there will be, however I doubt they will tear, the price it very tempting)
2 x 11 1 Sedona Bazooka Rear Tire | eBay (this will definetly tear turf)
2x11 1 GBC XC Master 6PLY Rear Tire | eBay (this is the tire that I'm using on the steer wheel and it definetly tears turn)
1 New 2x1 1 Carlisle ATV All Trail 2 1 Tire | eBay (these require me to go down to a 10" width which will be narrow for the rims)

http://www.ebay.com/itm/161916718256?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT (this pattern is a bit more open than the first option which will offer more traction, but is it worth the price)
http://www.ebay.com/itm/191838802866?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT (for as expensive as it is, this one is also on my short-short list)
