Refreshed to address the year-round driving needs of today's performance enthusiasts who may encounter intermittent light snow, the new Firehawk GT w/UNI-T High Performance All-Season tire line reestablishes the Firehawk GT name in Firestone's family of performance tires. Designed to allow drivers to feel the freedom of the road, the new Firehawk GT blends long treadwear & responsive h&ling with traction on dry & wet roads, as well as in light snow.
In order to confirm how the new Firehawk GT tires measure up to some of today's other High Performance All-Season tires, we compared the V-speed rated Firestone Firehawk GT to the V-speed rated BFGoodrich Traction T/A, Dunlop SP Sport Signature & Yokohama AVID V4s tires.
Our evaluation used 2006 BMW 325i E90 sedans, with new, full tread depth 205/55R16-sized tires mounted on 16x7.5" wheels.
What We Learned on the Road
Our 5.6-mile loop of expressway, state highway & county roads provides a great variety of road conditions that include city & highway speeds, smooth & coarse concrete, as well as new & patched asphalt. This route allows our team to experience noise comfort, ride quality & everyday h&ling, just as you would during your drive to school or work.
All four tires in our test delivered on their promise of responsive h&ling with comfortable road manners. As in previous tests, the Yokohama AVID V4s received praise for its comfortable ride & relatively low noise level, especially along the rough expressway section. Dunlop's Signature Sport was not far behind, also delivering a smooth ride & scoring well with our team. The BFGoodrich Traction T/A & Firestone Firehawk GT both displayed acceptable ride comfort, while generating minimal but noticeable tread & impact noise over the course sections of our test drive.
At normal road speeds, the h&ling scores for the Traction T/A & Firehawk GT were a virtual tie, feeling crisp & delivering quick response to the driver's input. The Signature Sport also h&led well, with slightly slower initial response to steering inputs than the BFGoodrich or Firestone tires. The AVID V4s counter-balanced its advantage in ride comfort with a small reduction in responsiveness versus the other tires.
What We Learned on the Test Track
Our 1/3-mile per lap test track course includes 90-degree street corners, lane changes & simulated expressway ramps. Run in both dry & wet conditions, the test track allows our team to experience the traction, responsiveness, h&ling & drivability normally only encountered during abrupt emergency avoidance maneuvers or competition events.
In dry conditions, the Dunlop Signature Sport felt very responsive & nimble, slicing its way through the lane change/slalom & around the tight corners. Subjectively the overall grip level didn't feel as though it equaled the tire's responsiveness, but this didn't hold back our team as this tire drove its way to the quickest overall lap time of this test. Very close behind was the Firestone Firehawk GT, which delivered stable cornering & balanced h&ling. The BFGoodrich Traction T/A was also easy to control at the limit, but lacked the ultimate grip needed to post the quickest lap time. Just like on the road, the trade-off in h&ling for ride comfort impacted the Yokohama AVID V4s' h&ling. Overall grip felt quite good, while steering response & cornering lacked some of the precision & stability of the Dunlop & Firestone tires.
In the wet we usually see larger differences between tires. In this case, however, the differences were not as big as often seen in past tests. Only 4/10th second separated the fastest to slowest tire, showing how close all four tires are to each other. In the wet, the BFGoodrich tire lead the way with the quickest overall lap time, fastest time through the slalom transition & highest steady-state cornering (average g-forces). The Yokohama lapped our course only 2/10ths behind, where its somewhat slower responsiveness & soft h&ling in the dry proved to aid feel & driver confidence in the wet by providing plenty of feedback & controllability at the limit. The responsive steering of the Dunlop resulted in a somewhat edgy feel in the wet. In close fourth place overall was the Firestone Firehawk GT, which didn't quite have the wet grip displayed by the other tires.
