Noticed lately my car has been riding very rough. I feel almost every imperfection on the road its crazy. Not lowered or anything. on the stock suspension. Tires are inflated to the proper pressure. i suspect the tires? but they have some decent tread left on them still. 18k on the car. i did notice my suspension being a little squeaky when it was colder. its annoying the car doesn't ride like a lexus anymore. gonna have to take it to the dealer when get the chance any advice or suggestions? all this rough riding is making the MY14 rattles even worse

thanks

 

if it's stock tires that came with the car, then yes, you're nearing the end of its life. new tires will make a huge difference. New York roads doesn't help either

 

My car usually rides like that when its cold outside and the first few minutes of riding around. After that it rides nice and smooth. Im lowered on Half Downs.

 

I have the same feeling. I recently got a C300 as a loaner from my 2015 IS250 f sport. It's the tires as the C300 were running Michelins and the stock bridgestones are horrible.

 

Maybe check the struts? Many people are saying that they tend to leak

 

I felt the same way when i turned in my 2014 lease with about 24k and got the 2016. I noticed a huge difference with how much more softer and pleasant the ride was and wondered why the huge difference. I narrowed it down to the possibility it could be the tires as everything else was pretty much the same.

 

thank you everyone for the responses. i think its safe to say it may be time for some new tires. I've read many posts about the OEM tires making for a harsh ride. going to take it to the dealer to have the suspension checked out and will probably decide on a new set of tires

 

The Bridgestones do have a really hard sidewall. Go for Michelins or Goodyear, they seem to have a softer sidewall so will improve the ride somewhat
