Thanks RPalmer,
I did the swap of the rear tires last night - worst part was breaking the new lug tires off the new rims - they were tight. Halfway through thought maybe should have a tire shop do it but I perservered and got the new lugs mounted on the rear with new stems and no LEAKS! . I used to do split rim truck tires, and large tractor tires they were easier I think due to size - the little tires are tough getting off - much easier going on.
First Impressions of Lugs Vs Turf - Lugs give a rougher ride (@8-10 PSI) but its a little easier to steer than turfs. Contact area - Turfs give a little more ground contact in the rear and are more forgiving FWD/REV as I found you can really make a nice divot if you are quick on the hydro.
Lawn cutting/appearance - much better with the lug tires - more uniform cleaner cut unless its a wet area then the lugs do leave an impression.
Overall I'm happy with the lugs especially the cut quality - I am going to experiment swapping the front with my turfs and see if that makes a dif in the ride. We have a 1.5 Ac under lawn with mixed bag of wet areas, roots rocks, planting beds, trees, so lots of turning and shifting the hydro..
Too tired (lazy)to post pics today time to have a

- maybe tomorrow..
