Well, to be honest no. The Sauber is a well-known tyre eater, like much of Group C (Including the Nissans R92CP and R89c, the Jaguar XJR-9, and the worst is the Toyota 88C-V). The Mazda 787B is the only Group C car that doesn't immolate its rear tyres in seconds, and it is very difficult to get any of the other cars to be as efficient.
Some suspension tuning can make the car a little less harsh on tyres, and if you have trouble with wheelspin practice modulating the throttle a little better. Not an easy thing to learn, but with practice you can keep the wheelspin out, even in a car as powerful as this.
If you fit a turbocharger to this car you will see a massive drop in tyre life expectancy - and the C9 is powerful enough as it is, in fact one of the fastest stock cars in the game.
As GeorgeMorley says, your driving style can affect tyres life as well. Try not to suddenly leap on the brakes, as this can cause slight lock-up, with damage to the tyres. Hard braking is the largest factor in tyre wear problems, because not many people know how much it affects wear and therefore don't do anything about it. Think of it in the same way as the throttle - if you hit it too hard, you're going to destroy the tyres.
Using a harder tyre compound does increase tyre life, and I would recommend running this car with R3s on the front and R2s on the rear - the front wears a lot less, so you can get away with a softer compound.
Using R1s could seem like the obvious action to take against heavy tyre wear, but this will also have a very negative effect on lap times. A compound as hard as R1s gives extremely low grip levels, and so using them on the rear of a 900bhp car means only very careful amounts of throttle can be applied. This, apart from being annoying, will slow you a lot overall.
Oh, and avoid running on grass or rumble strips too much - uneven surfaces like this do a lot of damage to the tyres.
So my recommendations would be to use R3/R2 tyres, not to modify the already-impressive power output and to practice being moderated and careful with the brakes and throttle. 👍
