Check your rims! If you can see a ring around the wheel,(easier to check on the front,but be safe and check them all)!! If that's the case,you have 3-piece rims,and Not the "Widow-Makers". The "Widow-makers",are split in the center,and the "lips" are solid on those. If you have older tires,add 5-7 lbs.,at a time,instead of filling them all at once. This will give the tubes time to expand,while reducing the risk of a blow-out. Hope this helps.
