As a player of both Project Cars 2 and GT Sport, I've found several interesting differences; some more perplexing than others. We all know that GT Sport doesn't simulate track conditions, so the Soft tyre will always be the fastest and the hard always the slowest. This seems fair enough, as the same thing happens in Formula 1. But this isn't the case with all categories. Most have a soft tyre for colder conditions, whilst the hard is used for warmer conditions. In some way it makes things simpler, as you only have to worry about the track temperature. This is the case with Project Cars 2. In addition, the tyre wear is also different to GT Sport, as they don't degrade constantly. Instead, they stay at a consistent grip level until they've passed 90% wear, at which point you'll see a reduction in lap times. This allows me to get into a rhythm, as I know the car will do the same thing each lap. This is not the case in GT Sport. The tyres are always wearing so it's not as easy to know how much grip you'll have each lap. This makes life more complicated as you're constantly having to adjust the way you drive. It's harder to manage the tyre in GT Sport compared to Project Cars 2, which confuses me. I honestly feel more comfortable playing Project Cars 2 as it rewards my consistent driving. The tyre model in Gran Turismo needs to be revised completely for the next game in order to solve this problem. The tyres shouldn't act like the ones in Formula 1, as it's a unique case to create "drama" and put more emphasis on strategy.
