[Mgs] Tyre life expectancy

[bighealey at charter.net]

Rubber degrades and becomes brittle after about 4 years.

At about 50 to 100 per tire this should not be an item to scrimp on.

Unless you do not drive the car in which case get some original Dunlop bias plys and shine n show away.  Just remember that you should only roll the car on and off the trailer.

Oh yes, you will need to replace those 5 year old trailer tires though.

I am on my third set of tires in 9 years and now looking at a fourth set after the parking lot solos a few weekends ago.  Yes I drive my car hard and a lot.
