Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix, AZ talk about how to take care of your tires and when it may be time to replace them. Also on this show:

• How driving an all-wheel drive vehicle might affect the way you purchase tires.
• Why you shouldn’t buy 2 tires at a time.
• How often you should be replacing or rotating your tires.
• The recommended tread-depth for your tires.
• 1997 GMC Van: The manifold intake gasket on my van is blown. I’ve heard about gasket repair fluids- would you recommend these products? If not, how much should I expect to pay for a repair?
• 2002 BMW X5: I’m having an issue getting my car into forward driving gears in the morning. What factors may be affecting this?
• 1998 Chevrolet Silverado: After this truck sits, I’ve noticed a problem with the engine overheating. I noticed a water leak but didn’t get any answers from the shop I took it in to. Any ideas?
• 2003 Chevrolet Tahoe: I recently had my fuel pump changed out. Since then, the gas gauge needle takes a long time to register how much gas I’ve refueled with. Is this something I should be concerned about?
• 2013 Chevrolet Silverado: After replacing all 4 tires, I’ve noticed some rough driving every so often. Is this normal for new tires wearing in?
• 2010 Chevrolet Aveo: I’ve noticed a “roaring” noise when I first accelerate. Where should I take my car to have this looked at?
• 2012 Hyundai Elantra: The reverse in my car suddenly quit working. After having the transmission replaced, I noticed the two AC hoses were dirty. Is it possible that these hoses were damaged during installation?

Cars talked about on this show are the 1997 GMC Van, 2002 BMW X5, 1998 Chevrolet Silverado, 2003 Chevrolet Tahoe, 2013 Chevrolet Silverado, 2010 Chevrolet Aveo, and the 2012 Hyundai Elantra.
