Commenting on tips
 

Comments on tips would be a nice feature. OR, links to forum posts referencing the tip in question.

For example, there's a tip suggesting that you can inflate your tires beyond manufacturer's recommendation, perhaps as high as the sidewall rating. You can, but you need to know that will cause excessive wear be reducing the road contact area the tires were designed for. There could also be handling problems due to reduced road contact. (As discussed over on AskMe in response to a question I posted.) Over time, your extra tire expense could outweigh your gas savings, especially if you overinflate more than a few pounds. The point is, readers of the tip will not see the necessary caution flag on this practice, without commenting or a link to forum discussion(s) on the tips.
