Thought I'd ask over on Wheels / Tires as I'm getting no takers on General...

I while ago I posted pics of my rear tire with a screw embedded. I had to replace the rear tires. So...In the front I have Michelin XGTV - probably about 2/3 worn and in the rear two new Michelin XGTV4 Pilots. One thing... the tread pattern between old & new (front & rear) is significantly different.

With the new tires in the rear I can feel a distinct side-to-side jiggle at the back end, more pronounced at higher speed.

I figured to begin with it was just something to do with breaking in the tires and it would go away - or I wouldn't notice it after a while. However, after over 1K miles it's still there.

Does anyone know what may be causing this? Could the different tread pattern between fronts & rears be doing this? - It's hard to imagine this being the case - but I'll bow to greater experience. Is it possible that improper balancing could be the culprit?

Any thoughts would be appreciated...

Yes to your tread question, and check the tire pressures. New tires rear with worn fronts is also a factor.

I had the same problems when I replaced my rears with brand new Dunlops SP9000. The moment I got Dunlops in the front (same tread pattern), stability at all speeds came back into my life ;-)
