We typically buy tires in bulk for our tire test program, ordering upwards of almost 1,000 tires a year. To spot check our advice and current tire buying, we recently purchased and had mounted three sets just as any consumer would. We found that it is possible to get a good, convenient deal, and our experts will show you how.

In a perfect world, a tire sealant kit may sound like a quick, convenient way to fix a flat tire. No need to remove the tire—just add sealant, inflate, and go. But, it turns out, there is more to it. To better understand the available products, we have begun evaluating several.

Even though winter is over, our cold-weather testing continues. We've just completed two tests with our latest tire group: stopping on ice and resistance to hydroplaning on standing water. And as the testing rolls on, we wanted to share some interesting new findings.

Consumers have a low level of satisfaction with run-flat tires versus more traditional tires, according to the research firm J.D. Power and Associates. These findings did not surprise us, though they serve as an important reminder for car shoppers who may be more focused on sheetmetal than rubber.

In recent weeks, Florida and Texas have crafted proposals to regulate the sale of used tires. Yes, used tires. In this tough economy, buying a used tire at the fraction of the cost of a new one is attractive and may even seem like a reasonable solution for replacing worn-out tires. But it is not.

Tire Pressure Monitoring Systems (TPMS) have been standard equipment by federal law in all new cars for about six years now. Despite their very real safety benefits, the tire-pressure systems can be a royal pain in the neck, and a costly one, for consumers and tire shops alike.

Automakers, chasing ever higher federal fuel-economy targets, have been turning to low-rolling-resistance tires for years to save fuel. In the past, we found that low-rolling-resistance tires could sacrifice braking to get better fuel efficiency. And at best, the tires will save you only 1 or 2 mpg. But tire technology is improving, and we're finding more models with low rolling resistance that are also good all-around performers.

We are just thawing out after spending a few days testing tires at Jay Peak Resort in northern Vermont. No, we weren't skiing. We were measuring snow-traction performance in severe conditions to provide expert insights for our upcoming winter-tire ratings.

At our test track, we found an easy recipe for cooking up a homemade supercar without resorting to tuner-shop tweaks that could break the bank or void the warranty.

Own a sporty cars or high-end touring car? Thinking about replacing the tires? Well, our next tire program will include UHP all-season and summer tires typically found on these cars. As in the past, we're also including evaluations of performance winter tires, which come in sizes to fit cars that use UHP tires.

About 13 percent of vehicles have at least one bald tire, according to a recent survey by the Rubber Manufacturers Association (RMA). When it comes to car tires, bald is not beautiful. It is dangerous.

Buying gifts for loved ones can be hard. You balance between what they need and what they want, what's reasonably priced, and what is an indulgent luxury. The same could be true for cars.

If you rely on winter tires and still haven't gotten them installed, don't delay. I'm reminded to make that public service announcement after an obscure government ruling held up my own winter-tire installation this year. Don't let this happen to you.

A new report from the National Highway Traffic Safety Administration (NHTSA) finds that vehicles equipped with a tire pressure monitoring system (TPMS) reduced the number of severely under-inflated tires on the road.

The recent Nor'Easter that packed a one-two punch to Sandy-stricken areas should serve as a call for northern drivers to start shopping for winter tires, or to have winter tires installed. There are some decisions to be made, and as we witnessed many cars slipping and sliding during the storm, the impact of those choices is clear.
