So i just got my winter tires on my g coupe and in the rear I put 225-55-17 instead of 235-50-17 and my rear seems to be very bouncy now. I did searched and couldnt find anything. Is the bouncing because i need a balance or alignment or is this a suspension issue? any help is appericated

I also checked the air preassure and they are fine

 

you might need new shocks !

 

really? I only have 30k miles on it and I don't push the car is there a way to check if it is the shocks?

 

What do you ride on when you aren't on winter wheels and tires?

 

I found out the problem it was my rims they were bent from the shop that put the winter tires on
