What a Difference a Day Makes!

My tires are 5 years old. I have 5000 miles on them, car is garaged, dry Colorado, garage gets 30 in the winter and 80 in the summer.

They will probably last longer than 10 years but I will probably change them out
In 5 years. Red lines would be factory correct, but my paperwork looks like they were black walls that my dad ordered.

I like raised white letters, but red lines would be cool.

I have red lines on my 69' 340 Dart Swinger. 35 years, total. On the 2nd set, at 20 years. I do check the side walls often for a possible crack, but I no longer race with these tires, but just putt around town and enjoy now and then opening the AVS up, to awake the 340. My reason for not changing the tires yet is, car is kept indoors (limited sun damage), always proper inflated (keep folds off the sidewalls), 3/4 tread (low milage) and never used Armor All, but Black Magic (gel form) for preservation. Used Armor All on my T/A Radials years ago and the sidewalls showed cracks in 2 years, with 1/2 tread left. My belief is the alcohol in the Armor All dries out the rubber and cracks the tire, unless you would apply it often. So now I keep all alcohol base products away from any plastic and rubber items.
