Thumbs down Bumpy Ride

I have had my 2008 IS250 (AWD) for about two weeks and I can feel every bump in the road. I have 17" wheels with Bridgestone Potenza RE92 tires. Not a smooth ride at all. Does anyone have any suggestions

Sports tuned suspension! You can try a diff tire but I have the er33 summer tire and they bite too. Mine are designed to wear out at about 10K I will try Michies and see how they ride.

Like most ride disturbance troubleshoots start by verifying correct tire pressure, there is a label in drivers door jamb.

Bridgestone designed those tires to last 40,000 miles. Lexus designed the IS to wearout the front tires at about 15,000 miles. As always your actual mileage may vary. Michelin tires are the best

Those tires are pretty bad, definitely check tire pressure and go from there. Oh, and check your tire wear, might have some uneven wear.

i had to get my front changed to backs after my 5000 service.. so.. and i am starting to slide already at 8000. I dunno what you can do but since i got my f-sport springs on my AWD it feels much stiffer... the bumps arent as crazy as they sounded with the stock springs.. it was like hitting a beach ball when i was going fast and went over potholes LOL... but yea now its stiffer so i dunno i like it more than before... doesnt feel as BOUNCY to me and that was my big issue, since i play avoid the cracks in the road when i drive.

Really? 40k? Like I said before, the sticker that said 11K was on the freaking window. Man that blows its designed that way.
