Air, we've never checked kart tire temps on asphalt or dirt. Now the asphalt big cars always did temps.Since tires are so important, do you guys ever use a pyrometer? I know most dirt guys don’t mess with them in cars because the tires cool to quick on the cool track, but in asphalt tire temps are paramount.
Also, Air or Nitrogen in the tires?
What Someone says in #4 above. As an aside, at the dirt track where I was crew chief for a buddy's son, we were able to get to the kart and take tire temps as soon as it came off the track (onto an asphalt apron) to wait in line for the scales. Because we could get to the tires quickly, we sometimes got info that helped us refine the setup, so, if the timing of your tire access is better than Someone's was, tire temps can help - but definitely best if taken with a probe type tire temperature gauge, not a laser temp gauge.
Took Temps for a season, sold the probe for a loss.I was also taught tip always use a probe on tires. Maybe temps could be beneficial during tests where I can stop him and walk right on the track and check temps. But, like Earl said, I might be overthinking things a bit for an 8 year old, lol.
I breifly remember a thread from December-ish where we all went round and round about tire temp collection. If I knew the title I'd link it here. Sure would save us alot of time.Took Temps for a season, sold the probe for a loss.
Much more interested in what they look like, and lap times for each lap compared to the rest of the field
