I have a 1250 that I bought new 23x10.50/12 turf tires at the dealer because they wouldn't fill the old ones because they had tubes. They didn't look bad but I didn't argue because I wanted the tires filled. I believe they only charged me around 20 bucks to fill the tires. I was told by both the company and the dealer that RG would add about 75 lbs per tire. They were really heavy. I have one set of IH wheel weights and chains on. I have had no problems getting stuck so far. I want to get more wheel weights because our yard gets really soft when it rains in the summer. I wanted RG because we have dogs and if one of the tires leaked, we would be safe.
Make sure you shop around the dealers in your area because I had three and all were different. Hope this helps.
