Interesting...and perhaps true. My experience has been positive...so far. It has been over a year since I put slime into the left front. It had not been deflating quickly but with a time span of a couple of days, I could see that there was a slow leak somewhere. I thought it may have been the valve stem but that seemed tight. I tried the old soapy water discovery but didn't get anywhere. So, we'll see how much longer it holds. Then, again, I use my tractor "gently."
Not a rough and tumble kind of person, I guess.
