they tried to run that scam on me at another dealership here... (which i decided not to do business with)

the SA said the vehicle would need to be brought back in for service for "modification" and "reprogramming" if i wanted to change the wheels..

and we're not talking about fender flares or anything....

she had no clue on what those mods were but i would have to pay for this service..(a couple of hours worth of labor!)

the only thing i can think of is resetting the TPM sensors and/or maybe adjusting suspension if the wheels are significantly larger (and in your case it isn't necessary)

i say if you can take your business elsewhere than do so.....who knows what else they will throw at you in the future?

just my .02cents
