THE UNUSUAL SUSPECTS could any of these NINE AFFORDABLE SUMMER TIRES have knocked off THE EXPENSIVE MICHELIN PS2? BY DAVE VANDERWERP PHOTOGRAPHY BY RICH CHENET caranddriver.com AUG 2009 03 TIRE TEST When in doubt, it seems, add adjectives. Just as the EPA tacked on “ultra” and then “super” in creating ever-more-stringent-sounding categories for its low-emissions vehicle ratings, the tire business is continuously inventing variations of its high-performance segment. There are now five categories of street tires designated exclusively for summer driving—grand touring; and high, ultra-high, maximum, and extreme performance. This category list is arranged in increasing dry-road capability, and those capabilities tend to produce trade-offs on tire wear, noise, wet performance, or all of the above. It makes our noggins ache trying to grasp how it is possible for a category to better “maximum,” and don’t say we didn’t warn you if there soon appears a “colossal” or, even better, an “extreme super colossal” performance category. Summer tires are one of the easiest and most effective ways to increase a car’s performance. When shopping for them, we usually consider those in the top three performance categories, so that’s what we did for this test, with one catch—we set a price limit of $140 each in a 225/45R-17 size. Naturally, the goal was to see which of the nine tire models gathered here is best at chomping the pavement and generating quick lap times. At the time of this test, Michelin, Goodyear, and Toyo didn’t have any tires that qualified for our criteria, so we turned to their subsidiaries— BFGoodrich, Dunlop, and Nitto, respectively—as well as low-price specialists such as Hankook, Kumho, and Falken. This also marks the debut of a Chinese brand in a C/D tire test. While more than 10 percent of tires sold in the U.S. are now manufactured in China by well-known companies, Chinese brands themselves are just starting to have a presence. Steady growth seems likely, however, considering the cut-rate prices: The TYPICAL SELLING PRICE SERVICE DESCRIPTION UTQG TREADWEAR rating WEIGHT, lb TREAD DEPTH, 1/32 in DIRECTIONAL BEST IN TEST Ling Long L688 $57 94W 280 23.1 9 yes Hankook Ventus V12 Evo $106 94Y 280 22.9 10 yes Yokohama S.drive $115 91Y 300 22.6 10 yes Nitto Invo $117 91W 260 24.6 10 no Kumho Ecsta XS $120 91W 180 23.1 7 no Falken Azenis RT-615 $121 94W 200 24.2 7 no BFGoodrich g-Force T/A KDW $126 90Y 300 23.9 10 yes Bridgestone Potenza RE760 Sport $132 94W 340 25.9 10 no Dunlop Direzza Sport Z1 Star Spec $137 90W 200 25.7 10 yes Michelin Pilot Sport PS2 benchmark $192 91Y 220 22.9 10 no tire brands, by price Ling Long L688s cost just $57 each. Some makers offer more than one tire model below our price cap, and in that case, we chose the one in the higher-performing category. And to see how this popular, lower-priced contingent performs compared with more expensive tires, we brought along one of our blue-chip favorites: the Michelin Pilot Sport PS2, which sells for $192 apiece. As with our most recent tire test [December 2005], we partnered with the Tire Rack for its expertise as well as our desire to use a nonpartisan facility. Clearly standing out from the competition, the company operates an impressive fleet of 3-series BMWs and Porsche Cayennes for its own tire testing and education of its sales force and generously allowed us to use a couple of the balanced, predictable, and pleasing 328i coupes for our test—the red one for dry driving, the silver for the wet. quid pro quo NOTES Service description: The two-digit number (90 to 94, in this case) specifies the load rating; the higher this number is, the more weight the tire can carry. The letter is the speed rating: W means 168 mph; Y is for 186 mph. UTOG tread-wear rating: This rating compares a tire’s wear with that of a reference tire. For example, a 340 rating estimates tire life at 3.4 times that of the reference tire, which scores 100. Directional: Tires with a directional tread pattern can be mounted in only one direction, which limits their ability to be rotated. 04 AUG 2009 We’d like to reward Spencer Geswein’s expert assistance with an unqualified plug. Aside from providing independent testing, training, and coaching services (www.full-lock. com), Geswein and business partner Brian Smith are also involved in the operation and development of Carolina Motorsports Park (CMP) in Kershaw, South Carolina. With 2.28 miles of asphalt, 14 turns, three track configurations, and a wet/dry skidpad, plus a dedicated karting track in the works, CMP has much to offer. The recent addition of Palmetto Motorsports Club allows enthusiasts to enjoy plentiful track time and first-rate facilities at an affordable price. CMP even has trackside condos available (www. carolinamotorsportspark.com). caranddriver.com MICHELIN PILOT SPORT PS2 We’ve always been impressed with the Tire Rack’s staff, many of whom are involved in racing and are genuine car nuts. Consider the vehicular arsenal parked in front of the company’s 530,000-square-foot warehouse in South Bend, Indiana, while we were there: an E39 BMW M5, an Audi S6, a Corvette Z06, a BMW Alpina B7, and a passel of other cars we’re fond of. A further benefit of this arrangement is that the Tire Rack sells most of the brands in the test; thus we could use tires from the company’s inventory and circumvent the possibility of tiremakers cheating by sending us a customized version of the requested tire. After each set of tires was broken in according to the Tire Rack’s criteria, three different maneuvers were conducted, each in wet and dry conditions: braking from 50 mph to a standstill, laps around a 0.3-mile autocross course, and runs around a 200-foot-diameter skidpad. The listed braking results are an average of six stops (after two stops to get the tires warm). On the autocross course, two drivers took three laps each, and the best time for each driver was added together. One driver performed two laps in each direction on the skidpad, and the best run in each direction were averaged, which is our normal procedure. To eliminate any potential bias, neither test driver knew which particular tire was being evaluated. Hankook offered three identical sets of “control” tires to be interspersed among the test tires. If identical results could be achieved with the control tires at different times throughout the day, we could be confident in the consistency of the data and that changes in the track surface due to temperature or any number of other factors caranddriver.com weren’t affecting lap times. But if the times were shifting, we could use that data to adjust the results accordingly. We also included a four-mile street loop to measure interior noise and note subjective behaviors such as sound quality, impact harshness, and steering feel. The two drivers were the author and, once again, Spencer Geswein—engineer and former racer and Michelin tire tester. His finely calibrated backside and expert driving skills provided another opinion on the subjective nuances among the tires, and he rated each candidate in three areas: grip, precision, and progressiveness. Summer tires are not designed to be driven in temperatures below about 50 degrees and certainly not in snow or ice. To us, they are about maximum dry-weather performance, with enough capability in the wet to get through a sudden downpour. So we skewed the results to favor the dry-pavement champs, giving double the weight to those tests, even though summer tires generally outperform all-season rubber in wet capability as well. After three days of testing, we were left with a bundle of lap times and even more notes, clothes that reeked of rubber, and left-knee bruises from bracing hard against the door during the highg driving. And we were surprised by how vast and noticeable the differences were among the tires, even to relatively inexperienced tire testers such as ourselves. Despite what some onlookers thought, we still call this work. BMW M3; Porsche 911, Boxster, and Cayman; Chevrolet Corvette ZR1; Cadillac CTS-V. A list of some of our favorite cars? Yes. And they all wear Michelin PS2s, which is probably one of the reasons many C/D staffers consider the PS2 their favoritesummer tire and a good enough reason to use it as our benchmark in this test. After which, we were understandably surprised that the pricey PS2s didn’t dominate the dry portion of the test, finishing only midpack in both autocross time and braking. Geswein thought excessive understeer held back the lap times. Still, the PS2s pulled an above-average 0.92 g on the skidpad and exhibited a very surefooted, predictable demeanor. Unlike most of the other tires, the PS2s were responsive to steering inputs at the limit and would tuck back in nicely after their grip was exceeded. Another positive is pleasant ride quality, noted in the street-driving portion.In the wet, the benchmark PS2s showed their mettle, feeling the most connected to the road and reeling in the quickest lap time—beating the Ling Longs’ dry time—and generating a heady 0.88 g on the skidpad, which was as high as two of the competitors’ best efforts in the dry. The PS2s’ wet performance was certainly impressive, but we’d like more dry capability from an expensive summer tire. —DV AUG 2009 05 NIT DUN LIN BFG TIRE TEST 59 SOUND LEVEL, AUTOCROSS 50 dry MPH, dBA TIME, BRIDGESTONE 61 seconds KUMHO HANKOOK 61 59.0 DUNLOP 59.3 YOKOHAMA 61 BRIDGESTONE FALKEN 6259.6 FALKEN KUMHO 62 59.8 HANKOOK MICHELIN BENCHMARK 62 59.8 BRIDGESTONE 60.1 NITTO 62 MICHELIN BENCHMARK 60.1 63 DUNLOP YOKOHAMA 60.3 LING LONG 63 NITTO 60.5 64 BFGOODRICH LING LONG 61.1 SOUND LEVEL, 50 MPH, dBA BRIDGESTONE HANKOOK YOKOHAMA NITTO INVO FALKEN Ling Long L688 61 61 61 KUMHO SOUND LEVEL, AUTOCROSS 50 dry MPH, dBA TIME, BRIDGESTONE 61 seconds KUMHO HANKOOK 61 DUNLOP YOKOHAMA 61 BRIDGESTONE FALKEN FALKEN KUMHO 62 62 Unfortunately, the Nittos’ performance was less inspiring.

Their fourth-place autocross time wasn’t spectacular, but they did outlap the benchmark Michelin PS2s. Geswein said the Hankooks felt “somewhat soft” and “imprecise,” although they were forgiving, yielding consistent laps with no surprises. Despite that feeling of softness, the V12 Evos somehow managed a second-place skidpad run of 0.93 g and were above average in braking. Hankook just launched a new extreme-performance Ventus R-S3 model, which wasn’t available in time for this test but likely has sharper dry responses. In the wet, however, the V12s were as sporty and connected as they come, with grip second only to the PS2s’ and the best braking. The Hankooks were extremely consistent, likely because they were so well-behaved, which made them easy to drive quickly. Subjectively, they felt the best around the track, even though their time HANKOOK VENTUS V12 EVO trailed slightly behind the Dunlops’. With above-average wet and dry performances, and tying for quietest on the street loop, the V12 Evo is an impressive and well-rounded summer tire. And, at $106, it’s a bargain, too. 1 Dunlop Direzza Sport Z1 Star Spec It took only a matter of seconds on the dry autocross to realize the Dunlop Star Specs were strong tires. Both the Dunlops and the Kumhos felt head and shoulders above the other tires, including the benchmark Michelin PS2s. We were impressed with how the Star Specs have huge grip that is available immediately, even before they warm up, which lends credence to Dunlop marketing them as autocross tires. Although 0.3 second behind the Kumhos DUNLOP STAR SPEC on the dry autocross, the Star Specs create a reassuring connection between the tires and the steering wheel. Geswein summed up their predictable and planted feel by saying they were “rewarding to drive hard,” and the Star Specs also excelled while transitioning from braking to cornering to accelerating, which left us with satisfyingly smooth laps. After the staggering dry performance, we were shocked that the Star Specs didn’t sacrifice much in the wet, knuckling down to produce the best lap time—just a 10th off the PS2s’—despite being a touch peaky. The only flaws we could find with the Dunlops were slight: above-average noise and a slight ride penalty, things we are regularly willing to sacrifice for performance when it comes to cars.
