you do realize that this system is for a car, not a bike, right?
the sensor swould be more meaningful when reading across a flat race tire, and tellls you a whole lot about suspension set up.
Dont think it would be as meaningful on a bike.
Did you read the article????
Tire: Michelin Pilot Power 2CT street tires
Hot Pressures: 30R / 31F
Ambient Air Temperature: ~70°F
Cold Temp: set to <120°F
Warm Temp: set to >120°F
Hot Temp: set to >170°F
Tire temperatures at start of session (no load)
Tire temperatures at end of session (no load)
LF: 102 – gain of 22°F
RF: 111 – gain of 31°F
LR: 124 – gain of 39°F
RR: 149 – gain of 64°F
Note: This bike had traction control, which limited rear wheel spin up on corner exits. Without TC, the tire temps on the exits of corners would have been much higher. The IR sensors are measuring the outside 2″ on each side of the front and rear tires.
Average Tire Temperatures: Notice that the average right side temps are about 20°F warmer than the left. This is to be expected as this is primarily a right turn track. Also, notice that the average rear tire temp is almost 30°F higher than the front. It would be good to work on getting more temperature into the front tire. This could be done with front to rear weight bias and/or front tire pressure.
Turn 1 is a right hand turn at the end of the back straight after very heavy braking. As soon as turn 1 is entered to the right, an immediate temperature rise in both the right front and right rear tires is visible.
Front Tire: The right front temperature begins at 105°F and gains 15°F within the first 2 seconds. It then gradually gains another 10°F ending at 130°F as turn 2 is approached. Notice the left front tire temp is uneffected.
Rear Tire: The right rear temperature begins at 135°F and gains 25°F within the first 3 seconds. During the remainder of the turn the temperature increases 5°F.
Turn 2 is the end of the double apex T1. Light and constant throttle application.
Front Tire: Front right side tire temps continue to slowly increase a few degrees through turn 2. Notice that as the bike is picked up off of the edge of the tire and as a turn 3 approaches, the tire begins to cool. Without the load on the tire it cools 5°F in less than 2 seconds.
Rear Tire: The right rear is under a constant light throttle load through turn 2 and the temps reflect this as they do not change. As the bike heads towards turn 3, throttle is applied in the short straight section. The resulting right rear tire temperature increases by almost 5°F for this short additional load on the tire.
Turn 3 is one of only two left turns on this track. It can catch riders on cold tires as the left sides take a while to warm up due to limited use.
Front Tire: The left side of the front tire immediately builds temperature upon turn in, beginning at 100°F and increasing to 119°F through the turn. The right side of the front tire is loosing temperature, dropping from a high of 131°F before T3, down to 114°F before entering T4 all within 10 seconds. The hottest left front tire temps occur in T3, and these are not very high. Notice that the time taken to reach 115°F by the front left was 5 minutes 45 seconds which is at least 4 laps. It’s easy to see why there are a lot of “incidents” in T3 at this track as there isn’t much time spent on the left side of the tire to build heat.
Rear Tire: The left side temps of the rear tire increase immediately on turn in beginning at 120°F and increasing to 153°F. The left side of the rear tire becomes the hottest in T3, and a max temp of 164°F was recorded in this session. The large increase in tire temperature is due to extreme lean angle and very healthy throttle application leading onto the short straight between T3 and T4. The right side of the rear tire loses temperature in this section dropping from 164°F to 150°F.
Turn 4 is the slowest corner at this track. It requires heavy breaking and exits on the back straight.
Front Tire: The front right side tire temp increases from 114°F to 125°F through this corner within 3 seconds.
Rear Tire: The rear right side tire temp increases from 149°F to 184°F within 4 seconds. This spike in tire temperature comes from hard acceleration while picking up the bike off the right side coming out of T4.
Turn 5 is a quick left kink before heading out on the back straight.
Front Tire: The small jump in left front tire temp can be seen as it rises from 108°F to 112°F as the bike is turned in to this corner. There is not much lean angle required for this corner, but the front tire temperature is still noticeably low.
Rear Tire: The right rear is under hard acceleration through this corner and the temps rise from 135°F to 142°F.
Turn 6 is a high speed right hand turn which leads onto the back straightaway. There is hard acceleration through this turn and the bike is leaned onto the right side of the tire for quite some time.
Front Tire: The front right side of the tire begins building heat through T6 starting at 114°F and peaking at 125°F. The left side of the tire looses about 12 degrees through this section.
Rear Tire: The rear right side of the tire sees it’s highest temperature in T6. The temps begin at 154°F on corner entry and build to 199°F before the bike is stood up straight. The rear wheel spin is being limited by TC, but it is still sliding some through this corner leading to the higher temperatures.
Turn 7 is at the end of the back straightaway and is a higher speed left hand turn after hard braking.
Front: The left front has cooled to 103°F and quickly rises to 116°F within 2 seconds upon entering this corner.
Rear: The left rear begins building temperature right after the front as lean angle and acceleration occur. Temps start at 119°F and build to 133°F.
Turn 8 is a right hand corner leading into the second slowest corner on the track.
Front: The right front begins the corner at 115°F and rises to 128°F. It loses a couple of degrees of heat as the bike is upright for a moment before turning into T9.
Rear: The right rear temp begins the corner at 159°F and rises to 169°F. There is only light throttle application.
Turn 9 is the last corner on the track and leads onto the front straight.
Front: The right front is already heated from T8, and rises from 123°F to 128°F.
Rear: The right rear temp begins at 165°F and only builds to 173°F. A bit surprised that there isn’t significantly more heat built in this corner, but perhaps the TC is keeping things in check as there is alot of lean angle. The rear is spinning when the bike is more upright but the sensor is reading the edge of the tire. Notice how much temperature is lost down the front straightaway. In about 17 seconds the right rear loses 42°F.
* Must get more front tire temperature. Add front weight bias and/or lower tire pressure
* Be careful on the front tire through T3 as it doesn’t build heat until lap 3-4.
* Be careful on the rear tire through T6 there is some overheating due to the rear spinning. This was not obvious until seeing the data
* Could further reduce TC settings and be more generous with throttle exits, being cautious through T6.
