</font><font color="blue" class="small">( The R4 tires have the tough "ghetto" bad boy look to them and many folks find them appealing from an appearance standpoint, myslef included. However, if you want the best traction with the least messing around, get the R1s. Answer this question for yourself -- How many big and serious tractors do you see running R4 tires? I would venture not too many. Since you have no lawn use planned and have traction concerns, get the R1s. Get some nordic style chains if you think you can justify the investment, but the R1s will handle almost anything except solid ice and mud so deep that you probably shouldn't be out there tearing things up at that time anyways.
You see R4s on construction equipment that sees pavement quite a lot and on CUTs. They look totally unstoppable and definitely give the tractor a different image, Hollywood style, but R1s give more traction. R4s are a popular compromise tire for CUTs that will see lawn service plus other uses. Just as CUTs are for many a step up from a lawn mower, the R4 tires are a step up in the toughness and utility image.
For others, the CUT is a small tractor, not an overgrown lawn mower. It will never be used to mow, so the damage done to a lawn is not important. The work is more important than the look, and R1s are the tires to use.
Heavy equipment that sees really tough conditions runs solid tires that resemble R4s but are not. R4s are supposed to be a bit tougher than Ags, but they can still get punctured.
Just think of your CUT as a real tractor and get the Ags. /forums/images/graemlins/wink.gif )</font>
Rich, I will get the AGS!
