Not a car tire. Got the bike back today. 2 issues with tube installed. First, the original angled valve stem is gone and now has a stubby, straight valve stem. This makes it impossible to check tire pressure and air up tire with my existing gage and air nozzle due to inacessibilty. I'm guessing I'll find an adapter of some kind to fix this. Second issue is there is no longer ground clearance under rear tire when propped up with Flip's paddock stand. For some reason the aspect ratio has changed (larger diameter of tire due to tube installation). Either is no big deal. Just thought I'd give an update.
