I have a few questions about my 2014 CTT.

1. It has Burmester sound system. The HD radio is quite flaky, often the signal changes from HD to non-HD. The transition is very noticeable and causes choppy sound. My question is why is the radio not able to pick up the HD signal consistently? My other rides have no issues. I live in Seattle area with broad HD coverage.

2. It has 17K miles. What upcoming maintenance should I prepare for?

3. It has 21" blacked-out wheels which are nearing replacement. Is this normal life (my right foot is usually light and weekend heavy!). Where do you normally buy tyres?

Thanks!
