Tentenths

Here's a website that I've found to be absolutely invaluable when it comes to trying to understand the intricacies of tyre/wheel specifications, construction and design.

It also includes a tyre/wheel size comparison calculator* that's really useful should you ever consider changing from stock sizes.

Great find, I think your post deserves a Sticky. :D

That Tyre-Bible link is quite good -- apart from the fact that they don't know how to spell what they're talking about :mrgreen:

One thing that's glossed over is offset, though, and this topic comes up here over and over. Another discussion and depiction of that is on the TireRack site, here.

Finally, I'm really glad to see on the Bible page the discussion of contact patch. It doesn't get into the thin-snow-tire vs fat-track-tire discussion, but it gives a solid background that some people just don't think of. HPH

Good information. For a quick calculator I like these:

The only caution I have is that the treadwall sizing is only an approximation. The best bet is finding specs from the manufacturer. I've found the sidewalls are usually shorter than advertised.

Check this one out, I use it all the time and find its even better than the Miata one. This calculator allows you to input not only the tire variables but wheel variables as well such as wheel size, offset, width. Then it spits all all the good info such as circumference, rev's per mile and even how far off the speedo will be @ 60mph.

Here is a third.

So what would be the difference if I took my stock 205/70/15's off, and put on 195/60HR/15's?

I know you're asking why... so I'll you. The stock 205 Bridgestones are beat, and the 195's are new Michellin's collecting dust in my storage unit... and they cost $150 each a couple of years ago.

And here's a question for "people in the know,"
With 16in rims, what the biggest tire I can put on it?
I see the tire converter, and the "plus zero" is 225/55/16, so is that it?

Wouldn't that be a thyrd?
