Tire Pressure Recommendations
A tire shop recently advised me to run my 205-75R-15 radials at 35 PSI. He said the additional air would improve the handling on my '61 and would be more economical on fuel. Any comments or recommendations? Regards.

I run my tires at 28 for cruising and 35 for storage to keep the flat spots away as much as possible. The radials we use are meant to carry a heavier vehicle. Try lowering the pressure for cruising, you may just like the result. I contend that I will replace my tires because of age before wear becomes an issue.

Try 28PSI, your car will ride a lot better and the handling will still be just fine.
I do not think you will replace the tires because you wore them out by running 28 PSI, it will be because they get old.

I think I'll try the lower pressure. I run about 35 in mine and its pretty rough on some pavement and in construction areas. My small town has cobblestone streets in places and driving on that will flat "shake up your innards".
I also think a stiffer ride may contribute to stress cracks over time.

While driving I run with 32 psi. at all times... until it is time for storage then its up to 50 psi. no chance of getting flat spots.

When I purchased my Diamondback radials for my 61 the salesman told me to go with 32psi which is what I use. Tires run smooth in town and highway and holding up well....Mike

The folks at Michelin HQ recommended 28 PSI for their radials on my 67. They have specialists on their "old car" help desk that said keep it at the high end of the original factory recommended tire pressure.
