Do those Tire Shine sprays pull the oils out of the tires speeding up the dry rot ? ? ?
I've never used them (I'm to cheap).
OP, do you park in a garage ? / that would help.
I had 103,000 miles on my first set of tires / I admit I ran them too long.
The second set I may get 65,000.
OP - Get yourself a Digital Tire Pressure Gage if you don't already have one.
There great for adding or removing air / quick and easy.
When I check my tire pressure, I fill out a Spread-Sheet along with the Temperature.
