I have a 2015 RTS, replaced the rear tire, changed from a Kenda to a Vredestein 205/60/15 per recommendations from the group. I'm now in limp mode! The codes are C006C (ECM module, VSS module), C003A (wheel speed sensor), C1290 (VCM voltage failure) and P2159 (vehicle speed not plausible). I took it into a dealership and they have replaced the ABS sensor and mentioned that bc I had an aftermarket rotor on there it's possibly not reading correctly. They replaced that as well. They now said that it's due to the age of the Spyder and they get really finicky and it's just the tire and I will need to have the Kenda put back in for it to run correctly. Has anyone else had issues with replacing the stock tire with a different size and has any advice for me. I really would rather not go back to the Kenda.
