This concern is absolutely correct:
".... but now its got me worried that the rubber may tear off from the rim at speed. I also plan on tracking the car, so not sure if its safe to do so anymore with the flexing. "

You need to either go down to 225 or spring for new wheels (can't use the stock rear 8"ers in front, those have the wrong offset). It will roll about just fine, but with either a pothole or a hard turn you can unseat the bead and blow it out suddenly - if it is in a turn you dig in the rim and the car usually flips. Both of those sizes are off of factory spec, so if the tire place that sold them to you told you they'd fit it would be worth seeking a return for the proper sizes. And jnu (above) is correct - even narrower tire:wheel ratio will give sharper handling and less heat buildup if you actually track it (225 on 8", 245 on 8.5" is working very well for me).
