Open question for any one, I have a Nissan Max 97 SE , and I have Borbet 17" tires . And tires are
about 8 inch wide. Why is when my car hits any bump or and pothole it's not stable the whole car like
moves and shakes,I mean is there any thing extra that I need to get installed or any change. I took it to NISSAN dealer he said this was not designed for this kind of tires, so I can't
fix it. So what is that I have to do to get it to run smooth or normal, any help would be really appreciated.

Thanks guys.

 

Look further up your suspension. Firmly push down on each corner of the car and count how many times the car bobs when you release it. If it's more than once or twice, your struts are shot.
