I've been watching Craigs list for some tires. I have only been paying attention to the 33x12.5x15 tires. I've seen some metric sizes that look big just basically ignored them since it wasn't what I was watching for.

Today I finally got around to finding a metric/standard tire size converter. I see that LT305/75R15 is a 33" tire, but how do I tell what the width is?

I guess I should have looked up what then numbers mean.

I found this site was a little easier to do the converting.

Now the search to find the tire closes to it.
Then enter the new tire and the "correct" tire here to see the difference:
