Which Turf Saver?

[atc110]

I'm going to mount some turf savers on 8x8 wheels and was wondering which width I should go with: 8, 8.5, or 9.5. Also there is the option of 2, 4, and 6 ply. What do you guys think is the best option?
Thanks

9.5 and nothing more then a 4 ply. 6 ply may be too stiff.

I agree, I have 9.5's on my R and there great. Just have fun in the rain and mud, you wont get very far lol.
