More wheel lift?
Prior to leaving, I checked and aired my tires to 35psi. While I was at it, I checked the manufacture date. The two front were made in 03-08. Over 10 years old. The two rears were made in 08-11, which would put them at about 7 years old. They haven't been on the car that long, Maybe 4 years, so they haven't been exposed to the elements for the duration of their life.
I can say that they hold traction very well. For that reason, when I had to purchase new tires for my truck, I went with the same brand. KUMHO.
Over the years, the Goodyears, Continentals, Bridgestones and other brands I've used have had problems with weather cracking. But I discovered it wasn't really the weather that was causing the so-called Dry Rot. It was the tire cleaner. Westley's Bleech White, Castrol Super Clean, and others. I discovered this because I was using the same products to clean my engine bay and my rubber products inside the bay were also rotting.
I've since found the only ArmorAll product that I will use. It's called Extreme Wheel and Tire Cleaner. Cleans the rubber well and doesn't etch the aluminum wheels where the clear coat has vanished. I've been using it for a couple years and have seen no degradation of the sidewalls on my tires. If you want a little extra shine, use the Kiwi Shoe Polish foam rubber pads after the tire is dry.
And by the way, for your local source of KUMHO tires, give NorthLake Automotive a call. He's a dealer and could use our support.
