Tyre Testing with 4WD Action and Cooper Tires

Cooper Tires was proud to play host to Australian 4WD Action magazine, who came to us to do some expert tyre puncture testing. The experiment was for an article on how to make your rubber better survive in off-road conditions. Our Technical Manager, Jeff Newick, was there to assist and advise.

The Tyres

We provided three different tyres for the test: an original equipment (OE) tyre commonly found on many top selling 4WD’s on todays market, our best selling all-terrain A/T3 (70/30) and the more aggressive all-terrain Cooper Discoverer S/TMAXX (50/50) with the tested and proven Armor-Tek3 carcass construction.

The Test

 

The Results

Unsurprisingly, the OE tyre did not impress – built for highway driving and lighter off-road duties than the other two tyres, it didn’t have as much rubber protecting the carcass plus it had a lighter internal construction which punctured relatively easily. The A/T3 was an improvement thanks to its stronger ‘light truck’ construction and extra rubber, but the true star was the S/TMAXX, which managed a remarkable 24 rolls over the spike at 14psi before finally being penetrated.

You can see each tyre’s results in the full article. (Australian 4WD Action, No. 217).

The Conclusion

 

Always remember though that once you get back on the black top to increase your tyre pressures back to road pressures to avoid any overheating or related heat damage.
