Lead the Charge: Hybrid Vehicles Need Hybrid Care – So Be the Local Expert

No sense in ignoring hybrid vehicles any longer. They’re here to stay. They are not a trend. Every year since 2000, the sale of hybrid vehicles in the U.S. has doubled. According to ABI Research, by 2006, sales of hybrid vehicles will account for 10% of the two million mid-size vehicles sold annually in the

Double Hit: Improper Torque Procedures Can Damage Wheels – and Business

It’s not difficult to torque wheel fasteners properly, but it’s not difficult to foul up the job, either. We’re not using double talk here; we’re shootin’ straight from the hip. The easy part of proper wheel fastener torquing is knowing the vehicle manufacturer torque specifications for a particular passenger car, light truck or medium truck,

Back to Basics: Part 4: How Tread Design Impacts Wear, Traction and Noise

In the last issue, we talked about tire compounds with the promise that we would delve into the world of tread designs this time. Always fascinating is the size of the contact patch through which the tread design must roll. On an average-size passenger car tire, the contact patch is about the size of a

Back to Basics: Part 3: Compounding Can Be Dumbfounding

In the last issue of Tire Review, we talked about belt packages and left you with the promise that next time we would dig deep into the subject of rubber compounding – particularly multi-compounding. To help understand the complexities of compounding (and there are many) grab a stick of chewing gum and pull it slowly.

Back to Basics: Part 2: Tire’s Belt Package Affects Comfort, Steering, Durability

In the January issue of Tire Review, we talked about the primary role of a tire’s bead and sidewall. Now, we’re going to move to the belt package. Let’s begin with some things you probably don’t know. For example, did you know that there are more parts in a tire’s belt system and carcass than

Back to Basics: Part 1: Beads and Sidewalls and What They Add to Performance

Did you know entry-level tire construction engineers, compounders and designers aren’t allowed to touch a new tire for a year or two? That’s because tire design and development isn’t part of any college curriculum. The making of a competent tire engineer isn’t the job of a college professor. That task belongs to veteran tire company

Winter Tire Blues: Auto Advances Add Complexity to Winter Tire Servicing

The snowflake branded on the sidewall of a winter tire isn’t there for decoration. The designation means the tire addresses three winter driving concerns: traction, cornering and braking. “Put on a set of today’s winter tires, and driving in the winter becomes irrelevant.” That’s a direct quote from long-time tire test driver Bob Strange, who

Right Repair Rates: Following Rules Can Keep Speed Rating, Some Tiremakers Say

ff cleaner. Goodyear adds this proviso: “If the hole shows evidence of fabric splitting, such an injury cannot be properly repaired using a standard puncture repair procedure. This type of injury must be skived out and repaired as a section (reinforced) repair.” But, while this will maintain the serviceability of the tire, it will also

Does It Rate?: Do We Really Need Tires That Can Do 186 MPH?

There are tire engineers out there who don’t much give a hoot about tire speed ratings. “It®™s not even a government regulation,” says one. ®There is no government test for speed ratings. The only speed-related test is euphemistically called a ‘temperature resistance test,®™ and it’s built around the ability of a tire to disperse heat

Get Pumped Up: Longer Tire Life, Fuel Savings Claims Heat Up Nitrogen Inflation

The gas from the past is making news again, and this time the story has legs. There’s nothing new about nitrogen inflation of tires. It’s been around since Texan Dr. Larry Sperberg brought it to our attention in 1968. That’s when he pronounced that a tire wears out from the inside out – a process

Tires and Towing: Before Your Customers Hitch Up, Check Weights, Load Capacities

Are your customers trailering boats, cars, horses or campers this season? They are? Well, are they checking the lug nuts on their trailers on a regular basis? Do they know how much air pressure their towing vehicle tires need? The most likely answer: an emphatic “No.” You are the one these people should be talking

Loads & Inflations

s. Fortunately, the gross axle weight rating (GAWR) and the gross vehicle weight rating for the entire vehicle (GVWR) appear on the vehicle placard. A quick aside: It is important that the cold inflation pressure for a motorhome tire never exceeds the maximum inflation pressure branded on the tire sidewall and/or the maximum load or
