I have run/flat tires. I just had my service at the dealer (it's still free) but they wanted to flush the fuel system and align the tires for 450 and 350 respectively. Wow, of course I said no. Just had my 4 wheel alignment, rotate done at Bear Frame and Alignment, They told me that they don't balance run/flat tires, is this true? If so, why? Oh, I did the injector flush myself, and the alignment only cost me 100.
