If you still have 2 Bridgestone summer tyres on summer wheels and just need 2 new get summer tyres.
Mixing summers and all season or winters is just a bad idea.
It's not just a bad idea. It may invalidate your insurance.
I mentioned to my insurance company that I fit winter tyres. They asked if I fit 4 and told me they would not cover the car if only 2 were fitted.
In extreme conditions the car can become unstable with only 2 winter tyres fitted.
