in contrast, many bicycle tyres made for street use are slick. aquaplaning does not present a problem for bicycles tyres due to their narrower width, higher pressure, lower speed, and circular cross section (due to the need to lean the bicycle in turns); the bicycle tyre can penetrate the water layer to contact the road much more easily. in practice, grooved bicycle tyres do not outperform slick tyres on wet roads. however, many low and medium performance bicycle tyres have substantial tread depth, because the bicycles are designed with off-road excursions in mind: in dirt, gravel or sand, the tread pattern provides significantly improved traction. in addition, high-performance bicycle tyres, although designed for road use only, often have a very fine tread pattern, which appears to provide no difference in performance versus a slick tyre and is only there for marketing purposes and as a tyre-wear indicator. this is clear not only from direct testing of tyres, but also from the fact that the texture of the road is itself coarser than the minimal tread pattern on these tyres. some grooveless designs have small "holes" or dimples embedded in the tread as a tyre-wear indicator. this is similar to automobile tyre-wear indicator bars, which contact the road when the tyre is worn to a low tread amount, making the tyre noisy on the road.

in a restart with five laps to go, 1997 and 1999 winner jeff gordon led 1994 and 1995 winner sterling marlin. a chain reaction began between the eighth and ninth positions after one driver missed a gear. five cars were damaged, including the defending daytona 500 winner michael waltrip, who spun into the pits and nearly hit the pace car being driven by jay leno. up front, marlin came through the gears a bit quicker than gordon, and took his momentum to the inside. gordon went to block only to turn himself. the two incidents brought out the caution flag, but under the rules at the time the field continued racing at full speed back to the start/finish line, and ward burton pulled alongside of marlin on the outside. marlin, his car smoking from damage to the right front fender, beat burton to the line by a nose, only for the red flag come out. rather than have the race finish under caution, the officials stopped the field on the backstretch so the track could be cleared and the drivers could race to the finish. concerned about damage on his right front fender, marlin got out of his car and tried to pull the fender away from the tire while the cars waited. because nascar rules forbid working on the car under a red flag except for non-points events, he was penalized before the restart and was sent to the rear of the field. burton (a resident of south boston) and elliott sadler (from emporia) were first and second for the state of virginia. 1986 race winner geoffrey bodine was the feel-good story of the day, as he finished third just two years after a crash that nearly took his life in the craftsman truck series' daytona 250 at the same racetrack.
