I have a set of tires that have not been off my 855 in thirty years. I tried to do some research here but it gets confusing.
On the front I have Goodyear turf tires 23 x 8.5 -12 & on the rear Goodyear 33 x 12.5-15 SofTrac turf tire.
The tractor is mainly used on 4.5 acres to mow grass (more like heavy duty weed chopping). And in between I use it for post hole work & box blade for grading & leveling. The entire area is good old red clay. The tires after thirty years are most likely dried out but they show no signs of dry rot. The tread is still in good on the front but rears half worn down. & it is hard. If I push down on a tread it has no give at all.
Operationally when pulling the box blade I can get a lot of tire slip & stalling especially on damp or wet grass/weeds. If I'm pushing in reverse I get better traction but when your box blading you need to go forward to engage the claws to break up the ground so slipping is a problem.
So I would like to get tires that will give me more grip & pulling but still be able to perform the major function which is weed cutting I'm thinking a Bar Type tire or what was called a lug tire. Now here is where I get lost. I see bar or lug type where the bars are at about 45 degrees. Then I see another type that looks like a half bar made up on an angle & then comes across the face of the tire straight. Is that what they call R type?
How stiff of a ride will I get? Turf tires don't exactly give you that Lincoln Town car ride either. but I would not want to get much more stiffer than I have already. Tractors have zero suspension unless you consider two lame cheap springs under the seat a suspension system.
Brands. I have looked at Carlisle & Kendra. Boht about the same price point. I haven't found any Goodyear as of yet but I would have no problem with the brand. And Firestone does not appear to have the front tire size I need with a matching tread for the rears which brings me to my other question. Does anyone ever mix the tread style between front & rear tires?
While I really am not too concerned over it, I hear a lot of objections on running lug or bar treads on grass. The stuff I have would never qualify as grass, but on the other hand I don't want to be tearing out what green weed coverage I already have. I have enough red ant volcanoes all over the place & I hate the color combination of red clay, fire ants & green weeds. So if anyone can offer some suggestions I would be grateful.
