A local tire shop would be best, but at the point they are worn, if you are driving them on the street, I'd say you were ready for a new set at this point anyhow.

Jason,
Not sure what you need from a local tire shop? You want them to inspect for...?
Also, I don't drive these on the street, ever. These have never seen pavement outside the track.
I run ET Streets because they make me eligible for 'Street Tire' shootouts at the local tracks. Full slicks make me ineligible to race in certain classes.
Plus, God forbid, I ever get a flat while driving to and from the track on my street tires, I can put the ET Streets on, pray for no rain, and drive home. No room for a spare when I carry two 28" tall slicks on board.
Personally as someone who has run these exact tires in this exact size the last 10 years, I don't think these are even close to being done - The ET Streets have plenty of tread left to race with, as a matter of fact the lower the tread gets the get the better I think they hook because they get closer to being a true slick. Again, I only run these so I qualify for street car events.
Please advise, as stated I'm a loyal customer, this is at minimum my 10th pair of ET Streets. This tire is clearly defective, it's splitting down the side.
