Brisdgestone Potenza RE002 - Car is much slower

Hello Everyone,

I am a proud owner of a 120D M sport and I recently change tyres to the Brisdgestone Potenza RE002 Andrenalin 225/45/R17 91W & 205/50/R17 93W.

Had them on for 3-4 days now and the acceleration is much slower than before. The handling is better obviously but I feel like I have lost 10% of power. Any ideas if this is just because they are new and they just need some time to adjust?

Thanks

thanks for the reply Dan116i, It's not a placebo unfortunately. The whole car just seems alot heavier than before and needs alot more power to accelerate properly. Fuel consumption is very poor aswell.
