10% increase in diameter may be a little xtreme.
Your correct, 235/70R16 is the OEM size although the owner may
have switched to 235/60X16 but who knows
Anyway, the 235/70X16 has a 10% larger diameter than the ODY
225/60R16 705rpm/mile vs 783rpm/mile (or 9.5% for the 215/65X16 size)
Thats quite a jump...
