[Healeys] Tire Recommendations? Yokohama

[Greg Lemon]

This is from memory, but a few years back "they" came out with a 
recommendation that tires be replaced every five years or so regardless of 
mileage.

What I heard or read is that that was a standard being pushed by the tire 
industry and that 10 is probably more realistic for a collector car.

Rubber dries out and internal belts can separate and delaminate over time 
regardless of mileage.

In my opinion take a common sense approach--if you have a car that is 
trailered to shows and gently tours you might extend tire life a bit, if you 
autocross or go on long highway trips you might keep the replacement closer 
to five years.

Exposure to temperature extremes and lots of sun has an effect on tire life 
as well.

One sign  of age is the checking or cracking on the sidewalls, but they say 
that deterioration is not always visably apparent.
