The pros are: it's a permanent solution.
The cons are: it's a permanent solution.

But seriously, the foam is heavy. Do you want to add weight to your tires? And if you decide it is too much weight later, it is too late. The foam is permanent and cannot be removed from the tire, unlike liquid ballast, that can be drained if you are not satisfied with the weight. Also, if you ever get into situations where you want to change the PSI in the tire, such as low traction conditions, can you do it with foam in the tires? I don't know. Also, there are several reports that foam actually lessens traction because the tires won't flex to conform to the ground. Steering wear and tear is also reported if you add it to the front wheels.
I don't have foam in my tractor tires, so I can't attest to any of this. Those are some of the reasons I stayed away from it. But I do have slime in my front tires(all four of my tires are the same size). I have turf tires and occasonally brush hog. I get punctures from the thorns. The slime stopped the problems. I put one bottle in each tire. Took about 5 minutes per tire. I still have two bottles of it left for the rears, but have never had a leak back there, so I won't use it until I do. So, I can honestly say that it works in my front tires and I haven't needed it in my rear tires.
My suggestion would be to use slime first and see how it does. If it does the job, great. If it doesn't, you haven't spent alot of money and you can then get the tires foam filled. Just be sure to tell them there is slime in the tires before you have them filled, in case there is some type of incompatability issue and they have to clean them out.
Here's a link to an article about cronic leaks.
And here's another link to an article at Carver's. Good article. See what they say about foam filling. You'll be surprised.
Now, I really hope this helps /forums/images/graemlins/wink.gif
