Yes. My current tires are loaded with calcium chloride. I would load the new ones also. As for the plies, These Galaxy 6 ply really don't seem to have that strong of a sidewall to them. I had 6 ply skid steer tires on the front of my 4210 and never had sidewall issues. These Galaxy's seem to slice up pretty easy. i was clearing some brush Saturday and the valve stem broke off the front tire. After replacing the stem, I noticed all kinds of deep cuts in the sidewalls of the front tires. I was only clearing small briar patches. May move up to backhoe or skid steer tires all the way around.

I've got the larger size Galaxy's on my 3320. I like them as they have more contact with the ground for better traction (?) over the smaller tires. they also hold more fluid for ballast. But...the biggest reason to me is to get the increased ground clearance in my stump-forsaken land.
My 3320 has such better clearace than my "old" 790. I dont have the stump hang-ups I experienced with my old tractor. (knock on wood)

I have the smaller R4's on both my 3520 &3720 for two reasons. There is a higher load rating for the smaller 6-ply R4 versus lower load rating for the larger 4-ply tires. I have a 448 backhoe on my 3520 and it is ballasted to the max with fluid and wheel weights. Also, if you contemplate using rear tire chains (an absolute must in Vermont), chains cannot be used on the larger R4 tires due to tight clearances between the fenders and tires, hence the smaller R4 tires on the 3720 which is also ballasted to the max.

Your correct on everything but the tire chains. There's a member here who's up in the taconic foothills with the larger r4's with tire chains. So it can be done. http://www.tractorbynet.com/forums/.../100581-3520-arrived-first-impressions-6.html

As a followup to my use of chains on the smaller R4's rear tires, I use a heavy duty spiked chain design, which has a noticeable height to it. If standard cross bar link chains are used, I see where they might possibly fit onto the larger R4 tires. In my case, due to icy conditions and mountains, the spike chains are essential for me. Especially with a 3x20 cab tractor, I'd be very concerned about using this style of spiked chain on the larger R4 tires and having any looseness that could cause damage to the tractor fender or fuel tank. The open station 3x20 tractors seem to have a little less "stuff" under the fender that could catch on chains maybe could accomodate the larger R4 tires with chains better.
