The TT is parked in a spot that is covered in wood chips....we took in out in Jan and came back to unseasonably warm temps so I had some mud to deal with.
As stated the tires are LT, not ST, with date code 50-10, so not even 5 years old yet. We didn't get a lot of trips in the last couple of years, so making me wonder if LT tires have less ability to endure sitting than ST tires.
I was planning to replace the tires this year, but looks like I need to do it in next couple of days before we leave on our Easter trip. Not what I wanted to see, to say the least.
