Yes, patching a tire is almost always cheaper than buying a decent used one. A professional tire patch costs $15-$30, while a usable used tire runs $25-$75 before you add mounting, balancing, and disposal fees that push the real total past $80. But cost is only half the story. Whether is it cheaper to patch … Read more

A tire is too damaged to be repaired when the puncture is larger than 1/4 inch in diameter, located in the sidewall or shoulder area, or when you spot a visible bulge, crack, or multiple damages close together. According to the Rubber Manufacturers Association (RMA) and Tire Industry Association guidelines, only tread-area punctures within these … Read more

So you’ve got a nail in your tire and you’re wondering: is a plugged tire actually safe at highway speeds? The short answer is yes—but only under specific conditions. A properly installed tire plug in the tread area can handle highway driving, but there are critical limitations you need to understand before hitting the road. … Read more

Picked up a nail and wondering if your tire can still be plugged? You need at least 2/32 inch (1.6 mm) of tread remaining for a repair to meet industry standards, but many tire professionals recommend replacing the tire once tread drops to 4/32 inch for better safety margins. Here’s everything you need to know … Read more

No. A tire with a sidewall bulge cannot be safely repaired under any circumstance, and the word “ever” in that question matters. I’ve walked dozens of customers through this exact conversation at the shop, and the honest answer is the same every time: the moment you see a raised bubble, blister, or bump on the … Read more

Yes, most vehicles with direct TPMS need a reset after tire rotation. When tires move to different wheel positions, the pressure sensors in each wheel no longer match the locations programmed into your car’s computer. A TPMS relearn teaches the system which sensor is where. If you skip it, the TPMS light may turn on … Read more

If you’ve recently inflated your tires to 40 PSI and now you’re wondering whether that’s too high, you’re not alone. We hear this question constantly from readers, and it’s one of the most common tire pressure misconceptions on the road today. The short answer is: for most regular passenger cars, 40 PSI is above the … Read more

If your new tire keeps losing air with no visible hole, the most common causes are a slow leak at the valve stem, an unseated tire bead against the rim, a tiny puncture (often a nail still embedded in the tread), normal air permeation through the rubber, or a cold-weather pressure drop. Most slow leaks … Read more

If you only have 30 seconds, here is the answer: check your tire pressure before a long drive, when the tires are cold. A hot tire gives a falsely high reading, and acting on that reading is how drivers end up dangerously underinflated the next morning. I learned this the hard way on a Phoenix … Read more

If you have ever checked your tires at a gas station after a long drive and watched the gauge climb 3, 4, or even 6 PSI above what you set that morning, you are not imagining things. Why does my tire pressure go up after driving a while? It is a normal physical effect: friction … Read more
