Are cordovan sumic good tires?

Sun Feb 18, 2018 9:13 am

Went to my local tire shop and they were having a special on them. Got good reviews just curious about the fuel efficiency rating on energy savings ( less drag on rolling)

If they are made in China, pass. International brand tires made in China are usually fine, but Chinese branded tires are generally inferior.

I've never heard of this tire brand nor model.

From a bit of digging (e.g. http://www.cordovantires.com/Warranty.aspx), it seems Cordovan is one of many brands at http://www.tbcbrands.com/.

I believe that every tire has a rating of its "rolling resistance coefficient"? or how much drag the tire has?
