Whereas the actual title of page is without 'PakWheels:'

It seems that Google is moving the site or company name to the front with a colon in some situations. I don't know if anyone has done a thorough study of it, but from what I have seen it seems to happen with sites that have a fairly solid brand established, but have page titles that are too long, keyword stuffed or for whatever other reason Google decides to alter what appears in the SERPs.

Google has been shortening or altering such longer and spammier titles for a while, but about a month ago these "Brand: xxxxx" titles started appearing.  To me it seemed funny because I have used that format on the home page of my own site and many others for a while because it just made sense to me. I guess Google thinks so too.
