What I've found so far with a very quick search...

"Radial vs. Bias Tires
All tires, from car tires to tractor tires, are bias-ply or radial construction. "Bias" and "radial" refer to how the tires are reinforced. Radial tires tend to be more flexible and for this reason are most often used for cars. Bias ply, on the other hand, are stronger and less flexible. Tractor owners usually opt for strength rather than flexibility, so most tractor tires are bias-ply construction. Radial tractor tires are available, however, and some prefer them because they have better traction and a bigger "footprint," causing less slippage."

I wondered as I noticed the tires mentioned were radial.

On another post, can't remember which one, a poster who went with radials complained about the rough ride which is just the opposite to what I would have imagined. My M8540 came with the largest R1's offered. Thankfully the radials weren't available without a six week wait, so I didn't get them.

My L5030 is however seven years old and needs new shoes on the front, so I am trying to decide which way to go. It has R4's on it now and I like them especially since I also have another tractor with R1's if needed.

I going to have to look. Honestly, I don't know if the tires on my tractor are radial or bias. I do know that they are rough riding as all get out. I just asssumed that it was because I went from R4's to R1's and the rough ride was a result of the much more aggressive lugs.:confused2:

From looking at the Kubota website only bias ply tires of two sizes are offered on the GL5740, one is a Hi Lug whatever that means.

I bought my L5030 used, so I really had no choice.

On my M8540, you have the option of bias ply or radial in different sizes. Of course I didn't since I bought it off the lot, but fortunately it had the big tires.
