Actually, I agree with you 100%. I was arguing with the dealer and even trying to do the math for them. I believe my snow tire sizes are exactly the same as the stock one (without sports pkg), which compared to my 19" sports pkg wheels + tires, the overall rotation diameter should come out to be the same.
The TPMS are already attached to the wheels when I bought them, so I don't know if they're in fact the Nissan ones. But since the 18" wheels are OEM, I would assume the same for the TPMS.
Btw, this dealer is also the only certified GT-R dealer within 200 miles of where I live tho...

The outer diameter for tires on the 18" wheels provided properly selected is the same diameter as on the sport wheels (i.e. when you go down in wheel diameter you go up in tire profile), there should be no speedometer error.
The TPMS system used is also the same so there should be no issue reprogramming.
Sorry but your dealer has idiots in the service department - go somewhere else.
