Unrelated to this site, but you guys have a lot of knowledge - my wife had her car in the dealership and among other things they sold her new tires - Sigma Regents - I have never heard of them - anyone familiar with this brand? Are they any good? Thanks for your input!

 

sigma is the brand name for the corporation that owns tire kingdom. they do have a website, but i forgot what it was.

 

Here is the website.

http://www.sigmatires.com/

I found it on www.google.com.

Hope this helps.
