More tire talk!

Does there tiny drivers ed course count? Though the size of that track would not allow the cars to go more than about 10 MPH. FYI, that course is used before the instructors take them out on public roads. Heh, when I took drivers ed, we used the elementary school playground!

Well I bought my corvair out of a farm field. Paid $150 for it. Didn’t come with a manual. Seems like 32 was the standard. Maybe some of you folks remember what it was like without the internet to answer all your questions.

When I took Driver’s Ed in 1969 at Albany High School in New York, there ws no school yard to practice in… The licensed students who, like me, were in the class for the insurance discount, usually started off out onto the streets first and then when we got to quieter neighborhoods, the non-licensed, permit holders took over…

I have written about my Driver’s Ed class previously and I did not get much wheel time.

Yeah I know, I was being a wise-@55, but by then I was already on my own and working a full time job as a machine mechanic at Fuller Brush on the evening shift…

Ah …… Mmmmmm …… Not exactly.

Ya’ see, when radials came in, they changed tire sizing systems - meaning you can’t compare the tire pressures between bias ply tires and radials without factoring in the differing systems.

The answer is that radial and bias ply tires have the same load carrying capacities at the same pressure and for the same size.

But to address the original post: I am pretty sure the local high school will either have to buy reproductions of the original tire or change tire size - which means the original tire pressure specification is invalid - the pressure will have to be recalculated. There is a way to use the original tire pressures, but it’s a bit technical for this thread.

I didn’t think so… Look pretty simple to me… :rofl:

Ah, but you need ten pressure gauges, then calculate the coefficient of variation and standard deviation between the gauges.

Then those lower pressures speced for grandpa’s 1964 Buick (24psi front and rear) or early ‘70s but still on bias ply Mercury (26-28psi) really were aimed more for a comfy ride? My gut, and not my brain, tells me otherwise.

Please do! This is an automotive thread.
