well, some of you guys know that i have been looking for 15inch tires for my 99gt to give it a muscular look/ fat tire look that is very uncommon on new mustangs

and i have been very upset about not finding tires that will help me be able to not have to recal.. in fact, the only ones that i seemed to even find taht were close were 295/50

and they were way off...

well, it appears that i am a dumb ***,, i already have a dallasmustang speedcal, and until this morning i hadnt even considered taht i could use that to recal for tire changes (since it IS designed to do that)

so has anyone ever done this? used it once to recal for gears, then do it again for different tires?

if so, let me knwo if it was as simple as removing it and replugging in the numbers that are required..thanks

[&o] god i worry about myself sometimes....
here is a link to show you that it shoudl be that simple....
