Hmmm..a Thunderbird front tire is the same dimension as ours, 110/80-18, but then the regular TBird also has only one front rotor. Must be a Thunderbird Sport hub, because it has dual front brakes and a 17" front rim. Wait though, if he laced that hub to a an America rim, then we're back to to the 110/80-18. So how would that effect the handling?
