+1 on replacing them. As tires age, the rubber will be hard, noise will get worse and traction will not be so great.
I just installed toyo tires proxes on my car. They are smooth and quiet. So far, I'm pleased with their grip and handling.
Fitted the new wipers and cleaned the mats. Also, the Magnaflow exhaust that I bought from 4wheelonline arrived today. I will install it this coming weekend.
