I know bias tires are preferred over radial tires for like bush hogging where past work has left hard stobs because they are more puncture resistant but radials give a better ride with less soil compaction.

My question has more to do with rear farm tread tires. In bias tires where you have the option of 8 or 12 ply for basically the same price (5% more for 12 ply I have had people tell me a stob will get either tire about the same under the same condition?

I can see the point that a 8 ply might have more give then a 12 ply but my thought is the 12 ply would be harder to knock a hole through the tire. I understand the 12 ply gives more load range because our size BKT in the 8 ply version max PSI is 25 but in 12 ply version is 36 PSI. In hard pulling the sidewalls would not deform so much at the higher pressure but may permit a stob to knock a hole through the tread with greater of easy?

Again I am talking about stobs and not steel spikes as in an old piece of equipment hidden in the bramble.

Our 16.9-28 are fluid filled. Is there an increased risk of a flat, decrease or no change in experience or from research with filled vs not filled rear tires?

I know old hard tires can better deflect stobs but I also know they make ice and snow removal harder due to less traction.

Get the 12 ply tires if the price difference is that low. Extra plies = extra strength in most cases.

As for filled vs. unfilled, I do not believe it would make a flat more likely if they were filled. Now as to the mess you may have in the event of a flat - That's a different story...

Snow traction - Lower the pressure in the winter a tad, and you'll increase your contact patch with the pavement. Filled tries would make a world of difference in snow removal.

The BKT AS2001 16.9-28 R1 tread 8 ply rated price was $505 and the 12 ply rated was $530 loaded onto our trailer. USA Firestone tubes were $65 each. Hope to get them mounted next week. Hopefully the 12 ply rated will be worth the extra $25. They look great.

Make sure they are really "plies" and not "ply rating." They may have several fewer plies than the rating.

I would expect 8 plies to have more penetration resistance than 6 plies with an 8 ply rating.

Pretty much since WWII every thing started moving to ply rating but still state like 12 Ply but may only be 8 -10 ply if you could count them.

Found new tire weight. In our size BKT the 8 ply rating are 173 pounds each and 12 ply rating weigh 181 pounds each so that is 8 pounds more per tire for what that info is worth. :)
