Volvo Volvo S40 2.5 T5 FWD M66 Tyres

I have driven these tires for about 500km now. i had the ps5 before. I noticed that these tires understeer a lot with a fwd car with a heavy nose 59/41. No matter the setup of the car, the tires wont bite at the front like the ps5 did. They were good for road use, but after 30 mins of driving at a low speed track (max 120kph) the tread looks horrible and I dont think they will last even a year, they understeer a lot under the weight of the nose. I have driven the same track with the Ps5 2 years ago, the balance was neutral with the occasional oversteer. With these tires, I cant even make the car oversteer if I'll try my best, even if I up the rear pressure to 3.1 bar. Just understeer. On the road they work well, they have a lot of straight line traction. They work especially wel in the rain, but they cant handle hard driving. Unlike my ps5 tires that lasted 50.000km. Will be putting SC7 or PS5 on the front axle as these are able to handle a heavy nosed fwd car
