The tire sizes specified for my 65 Bird seem to be 815 15 or 825 15. What is the modern tire sizing to equate with this or maybe better put is what tire size are ya'll using on your Flairbirds?

I replaced the 215s on my '65 about 2 years ago with 225s. I think it's the right size as the odometer is dead on accurate with the mile markers on the interstates now.

OK so if I understand correctly you're using 225 75 R 15's yes?

Thanks

Ken

Yes, that's what I've got!

Much thanks Randy 225's it'll be

Ken
