In 1996 My Dad (Rest In Peace) bought me 2 brand new Ohtsu oem atc 70 tires from the Honda dealer!!!! I have had my atc 70 ever since.. never really rode it as much. Fast forward the tapes and im teaching my 8 yr old and my 3 yr old to ride it. Last week i got a flat!! Sidewall damage where the tire meets the rim.. so i went to order a new set!!!! Boy was i surprised to find out they are no longer available. So my question is.. what are folks running nowadays on their 70's? Thanks in advance...
