I am in the process of restoring a 1934 Singer and it needed something
to roll on in the shop since it had no tires when I bought it. The guy at
the shop (that I do trust after 20+ years of buying from him) where I went
to get some scrap tires told me that unless the tires are in the sun,
modern manufacture tires should last at least 25 years. Might have been a
sales pitch since I bought all 6 tires (car carries 2 spares) but I would
have bought the tires from him anyway so he only got my money this year
instead of 2 years from now.
He did say that 10+ years ago, the rubber was different and tires didn't
last as long as now, sun or no sun. Time will tell, but I hope I didn't
buy my tires too soon if they are going to rot anyway. I did hunt the tire
websites and didn't find any info but they sure look good on the chassis
:) and I like being able to roll it around.
