Interesting. I'm not sure how the Security Contacts relate to the Travel Contacts. Looking at Continental's web site they seem like different tires for different intended applications.

I think the same applies to Schwalbe tires...Namely, you have to get the exact model for your intended application. For instance, there are several Marathon tire variants so make sure you get the one you need. There are quite a few previous threads talking about this.

Also, few shops are knowledgeable about touring so "...the best touring tires the shop had..." doesn't mean much in all too many instances. Best to check things out on BF, first.
