To help MotoGP riders get the maximum from their tyres, most if not all of the manufacturers have added a tyre-pressure warning light to the dashboard.

It's for performance rather than safety reasons and has been around since at least 2017. The aim of the light is to inform riders when they are overheating the Michelin rubber, which raises the tyre pressure, causing the contact patch to shrink.

Pramac Ducati's Jack Miller explained how he used the information to produce a late charge in Sunday's Czech Republic Grand Prix, enabling him to not only halt Cal Crutchlow's advance but surge past Suzuki's Alex Rins for third place with two laps to go.

Miller's margin of 3.5s to race winner Marquez also meant it was the Australian's best-ever dry MotoGP performance. But he couldn't help but wonder if he might have done even better by heeding the advice of the light sooner...

"I had the front tyre pressure light on pretty much the whole way through the race and it [the high pressure] caused me to have a few moments and I actually nearly threw it away," said Miller, who confirmed that riding in the slipstream of another bike or "braking really hard with a lot of angle" are the two main causes of high front-tyre pressure.

"Once I'd had the biggest moment up at Turn 4, I sort of buttoned off a little bit for two laps, maybe dropped half-a-second each lap. The pressure went down, the light went away and then the bike sort of came back to me and I was able to go forwards again," he added. "So I was a bit maybe pissed off with myself just for not thinking about that more early and trying to manage the front tyre a little bit better let's say. I felt I had really good pace there towards the end compared to the others, even Marc or Dovi..."

The #43 said he had initially planned to build his pace carefully during the race, a tactic Yamaha's Maverick Vinales had used to good effect before the summer break, "but it wasn’t possible at all because Marc got in front and just tried to screech away."

Miller eventually finished only one-second from runner-up Dovizioso (Ducati).

Speaking at the Brno test on Monday, Miller added that he should get the new Ducati fairing to use at next weekend's Austrian round.

Still to be officially confirmed as remaining at Pramac next season, Miller is currently seventh in the world championship and the top satellite rider.
