Breaking in new Tires?

[Dan LeBlanc]

I have mine at 35 now.  Noise is gone.  Vibration is gone.  Handling is much improved.  Fuel economy is up around 15mpg (although the car hasn't moved since July 28th as I've been too busy).

Back in the day, when converting any car from Cross Ply tyres to Radials, the accepted norm was to inflate the radials to 4psi over the recommendations for the Cross Plies.

Always worked for me, and I first started using radials back in 1967.   And this was years before the Steel Belted Radials came into being.

I run 32 in all my radials.

I noticed the recommended pressure was raised in 1979 which was probably done for fuel economy reasons.

My '52 recommends 24 pounds. I would NEVER run that low. Although I wouldn't necessarily go to the max, I would go to 28 or 30 pounds. And on newer models I would go to the 32 to 35 range. The low pressure recommendation was for ride, and it was suboptimal in every other way. Even on a '52 Cadillac, safety and handling are more important than ride. And I don't think the difference in ride is all that great.

My next tires will be radials that are as similar as possible to original bias-ply tires, but radials non-the-less.

As everyone else has noted, the "break-in" for tires is nonsense.
