Formula 1 has a habit of introducing new rules and regulations all the time to try and keep the sport fresh and exciting.
The success of these schemes can wildly vary, from the ill-fated elimination qualifying format to the bizarre double-points one-off at the final race of the season in 2014 in Abu Dhabi.
The jury is still out on Sprint Races already the FIA have made several tweaks since their introduction to try and increase their popularity among the fans and drivers.
Speaking on the Formula For Success Members Club, David Coulthard explained one change he would love to bring back to F1.
An awful lot has changed since Coulthard’s time in Formula 1 during the 1990s and 2000s.
Refuelling came and went during that time, and there was even a period when drivers weren’t allowed to change their tyres during a race.
The warm-up practice session on the morning of a race on a Sunday has also disappeared, as have spare cars which played a key role during one of F1’s most chaotic race starts.
Coulthard has now said that he would like to see another tyre manufacturer introduced to Formula 1.

At the moment, Pirelli provide all ten teams with tyres for each race weekend and have done so exclusively since the 2011 season.
The last time there was a ‘tyre war’ was back in 2006 when Bridgestone and Michelin were competing against each other.
This followed the disastrous 2005 United States Grand Prix where every Michelin runner was told not to start the race, leading to a six-car event that left fans at the circuit in Indianapolis fuming.
George Russell has voiced his concerns about Pirelli’s tyres this year, and if they face some competition, it might force them to up their game.
David Coulthard would ‘love’ to see competing tyre manufacturers in F1 again
Asked if F1 should switch tyre manufacturers after some recent problems, Coulthard said: “Well, I’m not really sure what the most recent big problems are.
“There’s certainly race to race quite a swing on tyre pressures depending on the loads they see.
“So, Singapore was actually down in the low 20s, which is kind of acceptable, I think the Grand Prix before was in the mid-20s, which is very high for a racing tyre pressure.
“But, I personally would love to see a tyre competition. We’ve got an engine competition, chassis competition, I know that Formula 1 would say that increases testing costs and therefore it becomes more expensive.
“But honestly, there’s a little bit of nose growing when people say that because Formula 1 is a very expensive industry and an expensive sport.

“I just think that it shakes the grid up week to week because if you’ve got for argument’s sake Pirelli and Michelin, there’ll be a circuit where Michelin are better because they’ve got the compound, the construction on that day.

“So, you naturally add another little twist in the performances of the cars.”
Coulthard then pointed out that there’s no longer a development race when it comes to engines because they can’t be changed during the season, and having different tyre manufacturers would add that level of jeopardy.
Pirelli tyre tests giving drivers opportunity to shine outside of Formula 1
Formula 1 teams are incredibly limited in the testing they can do outside of race weekends.
However, one opportunity where they can run the cars in private sessions is during test days working with Pirelli on their tyres.
Mick Schumacher has impressed when called upon to test for Pirelli for various teams on the grid this year.
The Mexican Grand Prix this year will also see an extended practice session take place so Pirelli can gain further data on their tyres for 2025 and 2026.
The introduction of another tyre manufacturer would create an added level of intrigue at every race.
Teams already use different power unit suppliers and build so many of their own parts, having another factor that could shake up the grid wouldn’t be such a bad thing.
