2 separate blow outs on I-75 S/B in Georgia (Fifth Wheel)

So sorry to hear about your blow outs. Come over and join the Montana Owners forum. There is a whole section on tires there. We bought our Montana, joined the forum, read the tire sub forum and couldn't get rid of those Marathons fast enough. You'll find other bits of invaluable info there too. You won't be able to see much until you register, so don't let it throw you off if you go over to just "check it out" it looks like there are no posts for over a year till you join.
