Need help! Purchased Dunlops Zed 1's from Jim @ Tire Rack, great service! 215/45/17 F / 255/40/17 R. Mounted them, had the car aligned.

Now car when shifting from one gear to the next, I feel the car steer to tha right. The guy doing the alingment could not bring up to spec the Right Rear Tire could that be the cause?

Any thoughts?
What are the OEM alingment numbers? Gonna take car back soon for a re alignment.

Any assistance...greatly appreciated.
