I put Slime in my 1025R tires about 2-3 years ago. Has worked fantastic until a few months ago. It's been horribly cold and I noticed a screw in one of the tires. I need to plug that up, but haven't had any major issues with that tire pressure. The other tire doesn't seem to be able to hold pressure lately. That tire seems to be delaminating. Noticed last night that it was out of round as I brought the trash back. I may have operated it too many times when it was low. With the Slime in there I have never worried about tire pressure. I'll post again on this one.
All of them most likely have Honey Locust thorns in them. And lately they seem to loose their charge.
Anyone know if I can just add more Slime or do I need to remove the tires, clean them out, then replace and add more?
