Let's talk about trucks

If you notice, that why I included the word "should" in my reply.

In reality, all sorts of people used to struggle with the "aspect ratio" portion of tire sizing.
That is made somewhat easier with P-metric.

Notice I used the word "somewhat".

Not really aimed at you, RRR, but at that other guy that likes to red X me on both facts and clearly stated as such opnions.
I understand. I get um sometimes too and just keep on truckin. lol
