I bought a set of Universal tires (21") for my '28 Phaeton about 35 or 40 years ago. I bought them because they had the original Firestone tread/sidewall design of the 1928 Firestone tires. I have been driving on them for about 15 thousand miles and two are in need of replacing, and the other two are not too far behind. While I like the original size (smaller than today's - wrong design - Firestones) of these 40 year old tires, I am disappointed in their short life span. I have had today's modern Firestone tires, on two different cars, which I drove every day for thirty years. They NEVER seem to wear out. Sadly that is not the case with my Universal tires.
At the time I bought my Universal tires (35 years ago) I also bought a set of LESTER tires. However, I never did mount them - they are still in the paper wrappers. So I can not give any testimony to their durability.
But I would LOVE to have a set of the new GoodYear tires - original 1930 design; however, as they are fairly new, they have not yet had a chance to be judged as to their long term durability and wear.
