So I've noticed this once or twice on one of our decreasing radius highway on-ramps. When I take this at a decent clip, I get a feeling like tread walk or sidewall rollover, but can't believe that's what it really is (I'm running Z rated RE960's at a confirmed 38 cold PSI). Lug bolts are torqued to spec.<p>I don't hear skidding or feel like I'm just losing traction and understeering momentarily. Any ideas what might be going on?<p>70k miles.

As the ramp radius decreases you probably ARE encountering a bit of understeer.<p>to corner that fast you'll need a bigger sway bar and/or a strut brace to keep the tires square to the road.

Re: Strange feel on high-speed turn.... Possible causes? (ss60)

I autocross, so I think I know what understeer feels like. This is different -- much quicker to take place (really feels like tread squirm on the snows, only perhaps a little more severe) and more transient (doesn't last very long). <p>And I have a bigger sway bar. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

How long have you been running your RE960's?

Less than 10,000 miles, since they come off in favor of the Dunlops in winter. I'm quite happy with them still -- they're quite grippy.

Decent tire but you WILL feel this on a Volv.<br>Unless you run ultra high performance <B>DRY tires </B>, have sway bars and generally a good suspension set up, this is it!

If something's broken or going south, I want to address it before autocross season kicks in.
