I have a slight vibration at higher speeds, don't feel it when going slow.
What is it most likely to be?
- Lost balance weight on wheels
- Suspension setup?
- Other?

Tyre wear leading to unbalanced wheels and/or incorrect pressure

Get them re-balanced a make sure the pressure is set correctly

If wear is very bad - you may still get vibration - then it's new tyres.

I had a vibration problem with the right rear wheel (it's possible to determine which wheel if your "seat of the pants" sensors are good). Turned out to be low tire pressure caused by a nail stuck in the tire.

I had a vibration problem when I bought my car - the dealer put on new tires - didn't go away. Balanced the new tires three times - got better but didn't go away. Took it to a wheel repair shop - bent rim replaced - car drives like a dream well into three digits. Start with checking your tires and work your way out. Best of luck.

Probably a dead animal inside the tire.

Or a balancing issue.

Take your pick.

Could have been a squirrel :-) plenty of those around here ...

The tire pressure was way off. Fixed now and seems to have solved the issue.
However I'm not sure what tire pressure I should have!

I have Pirelli P7000 tires
Front: 225/40 ZR18 83 W M+S, now at 36psi
Rear: 265/35 ZR18 93 W M+S, now at 38.5psi

Had the same and it turned out that my left rear wheel was very slightly bent on the inside (couldn't see it at all). A good balancing job made it completely dissapear.

I, too, had vibration problem and it turned out to be bent rim.

magnus: your tire pressure is off in the rears... I believe it is 36/44 on 18s...

Did you have to buy new rims, or were they able to do anything to your bent rim?

thanks
