If you could look over the shoulder of a tire designer working to balance all of the requirements for a new Standard
Touring All-Season tire, you would see a game of give and take. Nearly every major attribute of the tire has its
opposite. Gains in one often lead to a trade-off in the other. And in any tire, improving its rolling efficiency to
increase vehicle mpg often results in a reduction of wet traction.
Continental thinks they have minimized the trade-off in wet grip while delivering lower rolling resistance and long
tread life. That solution is the Continental TrueContact featuring EcoPlus Technology. To sample the TrueContact,
Continental invited several members of the Tire Rack team to experience its wet traction and road manners. The
evaluation used new 215/60R16 tires on a BMW F30 328i sedan.
Road Ride
Drivability under everyday conditions is a critical aspect for any tire in the Standard Touring All-Season
category. How smoothly does the tire ride, how quiet is it as it rolls over the variety of surfaces you encounter
during your drive, and how well does it handle and respond to your inputs?
Our road ride evaluation consisted of driving around a three-mile asphalt oval featuring several pavement textures
and a variety of surface imperfections to test ride quality and noise levels. Handling, steering feel and
on-center stability were evaluated by simulating driving in surrounding traffic, such as lane changes at various
speeds and maintaining lane placement around sweeping curves with a strong cross wind.
In this test environment, all three tires drove well and as expected for a Standard Touring All-Season tire. Minor
differences were noticeable only because of making the direct side-by-side comparison. Any of the three would be
fine for everyday driving.
The Continental TrueContact displayed good steering response and a tight, connected feel on-center when driving
straight ahead. The ride was comfortable with good control over staccato bumps. Noise levels were minimal with
only a hint of whine on smooth asphalt and minimal booming on bigger impacts.
The Ecopia EP422 rode slightly better over the smaller bumps, but when it encountered repetitive impacts or larger
bumps it felt a little less controlled and jounced around somewhat. Handling was not as direct as the TrueContact,
with a small vague spot right at straight ahead.
The steering feel of the Michelin Defender was very responsive once the turn was initiated, but when making minor
corrections within the first few degrees of center it felt just a little slow to respond. Tread pattern noise was
minimal, but there was some audible boom associated with larger impacts.
Wet Handling
All three tires were found to be fairly close during regular road driving in dry conditions, but the real
separation came in the wet when asking the tire to perform during a panic stop or abrupt avoidance maneuver.
For consistency we used a dedicated wet test track. Several drivers ran multiple laps until consistent lap times
were achieved for each driver. The .95-mile course featured a water system to consistently wet the track where
most turns were driven in third gear with several tighter second gear turns, and peak straightaway speed at just
under 65 mph.

In the wet, the TrueContact was in its element with good overall traction. Our test car felt composed in every
situation with stable and predictable handling. If the car did start to slide, breakaway was gradual and easily
controlled.
The overall grip level of the Ecopia EP422 trailed the TrueContact. Cornering traction seemed to be somewhat of a
struggle, which led to some instability, particularly at the rear of the car during transitional maneuvers.
The Michelin Defender responded quickly, but didn’t have the steering authority of the TrueContact. Overall
stability during abrupt maneuvers showed a small tendency towards gentle understeer, which kept the rear of the
car inline unless provoked into a slide by driver inputs.
Wet Braking
We took the opportunity to instrument the car and measure 60-0 mph, ABS-assisted stopping as a way to gauge
ultimate braking traction. Multiple stops on each tire were averaged. Like we found on the wet track, there was a
noticeable difference in ultimate braking traction across the three, with the TrueContact showing a clear
advantage.

Conclusion
During our brief encounter with the Continental TrueContact it seems to deliver on the goals of good road manners
plus excellent wet traction. Our introductory drive didn’t allow us to evaluate dry traction, winter weather
performance or fuel consumption. We’ll have a chance to put the TrueContact to the test during our full tire
evaluation later in 2014.
