John, are you sure that ALL bias ply tires cannot get DOT approval?

Hello Pat,

Sorry, you misread my post. Bias ply tires can be DOT approved. Someone else posted that they could not, and I was correcting that.

The only bias ply tires (legally allowed on the street) that won't have a DOT stamp are originals made prior to 1968.

With using such low psi, don't you get uneven tire ware ? (outside tred)
Or is the psi with bias-ply different ?

I would hate to ruin my expensive Billboards, which I haven't mounted yet.

You have to remember that each tire is only carrying approximately 700 pounds over a fairly large foot print.

I did a couple quick burnouts in the garage to make sure I had a good footprint and that is where the 18 PSI came from.

Just noticed I forgot to mention one item. The recommended pressures on Rogers site are 20 PSI cold. If hot, they are 27 PSI.

Here's the Krause info on tire pressures for "Vintage Tires". I'll also include their advice on tire "direction"...

Sorry, it says "upload failed". Just go to their site and look under "Information", then browse the PDF files.
