Best tire calculator out there

I get a lot of PM's / emails about tires and sizes, so I figured I'd make this a sticky so it doesn't get lost.

This one is great you can side side by side comparisons of up to 5 different sizes

Same one I always use to. I was gonna post it if you had something else.
 Only thing I dont know is what 135s and 165s would be.
 165/80? 135/80?
