XKR Front End Vibration

Just from personal experience on my mercedes, vibration is not necessarily coming from the front tires. Where do you feel the vibration in your seat or in the steering wheel?

Which version of the Falken tyre 451, 452?

The vibration is almost 100% in the steering wheel. At 75MPH one can see it.

They are FK 452.

Hmmm. I cannot think of anything other than balance or simply a bad tire that would cause this. (perhaps someone else with more knowledge than I, can?).

Have you rotated the tires front to back to see if the problem goes away or moves?

Thanks for the input. The tires balance perfectly and are nice and round. I can't rotate them front to back because the rear tires are larger.

How do you know they are "nice and round"? Also it is possible to get vibration from tires due to differences in sidewall stiffness that would not show up as an imbalance or out-of-round condition. There are balancers now with load-roller devices that can detect this. See example at link below.

Thanks, I'll see if there is one in my area.

My front end vibration on a 1999 XKR was a sticking front brake caliper, there was only a very slight pulling effect on braking from normal speeds so could easily get overlooked. Worth an investigation, the Jag part was expensive, but the work can be done by a local garage or DIY.

Best of luck. Howard

Thanks, Howard.

I believe it is either uneven tire wear, sidewall anomalies, or sticking brake calipers.

Thanks, Alan. I'm going to put a set of Micelins on it and we'll see how that goes.
