Just replace my rear tires - its been like less than 100 miles since I have them- I smell some stinky rubber odor I think its from the tires...

Is that Normal? How long should it last?

call the Tire Rack immediately.

could be the release agent they use to seperate the tire from the mold.

It should go away after a few hundred miles.

If not, I'd say you have a problem.

Call the Tire Rack and ask them for help right away.
