Goodyear Self-Sealing Tire Targeted at Work Truck Market

It wasn’t the first time a self-steering tire was introduced for the truck market, but it made an impression nonetheless.

While Goodyear scientists and officials touted the virtues of the company’s latest commercial offering, the DuraSeal tire, just prior to the opening of the World of Concrete show in Las Vegas in March, truck writers stood around gleefully taking turns at puncturing that very product with a nail.

So did Goodyear’s press conference blow up in the company’s face?

Nope. Like a certain battery-operated bunny, the darn tires just kept going, maintaining their psi even after they’d been punctured several times in the very same place.

“In testing we punctured one 24 times in the same hole – and it still didn’t deflate,” said one scientist to this reporter, who just couldn’t accept defeat.

With tires the No. 2 truck fleet expense after fuel – a truck tire has an average life span of only three weeks when used under the most punishing conditions, such as garbage trucks hauling loads into landfills – Goodyear’s new product is expected to make its mark.

Company officials said the new technology can extend the life of such tires to about six times longer.

And yes, retreads are possible, in fact, as long as the retreader knows the sealant (a coating inside the tire) is there, the sealant will remain functional for the life of the tire, say officials.

A yellow gel, called DuraSeal, is placed inside the crown of the tire as part of the belt package under the tread. When a truck runs over a nail, the gel surrounds the nail and seals the puncture, whether the nail comes out or not. (The seal won’t work for sidewall damage, however.) The gel’s presence can be detected on the tread – it’s bright yellow.

According to Goodyear officials, DuraSeal can seal tread punctures up to one-quarter-inch repeatedly, without the tire needing to be repaired or the sealant needing to be reapplied. And the sealant will work efficiently from -40F to 100F, says the company.

As far as cost goes, the tires should cost about US$300.

The Unisteel G287 MSA mixed service tire, with high mileage tread compounds and improved belt package and computer-generated tread design, replaces the G286. The tire is highway friendly, with a wide footprint and flat tread radius that delivers up to 40% more miles to removal, compared to the G286, according to company officials.

The G288, which also replaces the G286, targets tough-tire applications, including logging, construction, mining and other off-road applications. Its tread compounds and wide footprint with 19% increased tread volume provide up to 30% more miles to removal, it is claimed. Tearing and cutting resistance has also been beefed up – a new severe service tread compound on the G288, as well as an improved belt package deliver 18% better resistance to cutting, chipping and tearing (something not provided by DuraSeal).

Both the G287 and the G288 include a pitch sequence in the tread design that provides a quieter ride, (in testing, the latter’s noise levels were reduced by 3.0 decibels.)
