not sure whether it's worth fighting over. the dealer did perform the service they said they would.... I assumed it wouldn't be an exact match, I just didn't realize it was already pretty close to the limit. The strange thing is that the stock tires that came on the vehicle were about 33"..... it's odd that there is this little adjustability in the "module".
As far as inline devices go, I haven't looked too hard, but I think it's been discussed that there are no inline devices available for this model.
