I went for a road trip shrotly after I switched from my Dunlop Wintersport M3's to my old PS2s with 5K miles on them. I rotated the PS2s front to back when I made the switch. The side-hop was <b>terrible</b> on the highway, even in sport. Much worse than ever. I just checked with a tire-gauge and have inner tread depth on the rears of 5/32 and 6/32 in the middle and 7/32 on the outside. Wear is even on the fronts. <p>Possible indication of improper toe-in alignment? When I got the bushing fix I asked the shop foreman to make sure they did the R specific toe-in, but I never saw the alignment spec sheet. Should I spring a hundred bucks for a new alignment just to be sure before my next road trip in a couple of weeks? At this rate I will chew threw the PS2s in 10K miles!

I'd rebalance as well. Could be this too...

Rears were worn according to him. Camber is most likely the cause.

So the INNERS were worn on the front, quite odd. Every R I've seen has the OUTER fronts worn after 6K miles.<br>You were quite out of alignment

Seems like alignment.<p>I had similar problem but despite good alignment the side step sensation continued.<p>Delaer changed the lower rear arm bushings under warranty.Now the car is perfect.

Re: Increased Side Hop + Inner Tire Wear == Alignment Needed? (vizwiz)

You can get an indication of a camber problem by simply sighting along the side of the car. You can see if there's a gross difference between front and rear by kneeling down and eyeballing the wheels, like this... <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/sly.gif" BORDER="0"> <p>Shouldn't be<I> too</I> much difference front to rear and should be the same side-to-side.

just go back to the PZero with a GOOD tirepressure and then all the magic of "new PS wow amazing compared to the shhhtttt worned down pzero...ARE amazing" hocus pocus ... new tires are ALWAYS amazing...even new PS compared to worned down PZero's <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> just my 2 €'s <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0"> <p>PS <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> PZero is still the ONLY tire approved for the R <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> -> You CAN'T order a different tire OF-FACTORY <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <br>and like the real sport, you must be stupid to put something else under her...the chassis is set for PZero...the SW that is <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> ..blablablabla...sissies.....

Re: Increased Side Hop + Inner Tire Wear == Alignment Needed? (vizwiz)

Shelled out $159 for an alignment today to the latest specs. The car was actually nominally within spec, only minor adjustments were needed. Something else must have caused the increased inner wear up front? I am guessing that when I rotated the fronts to the back the uneven tire wear on them caused the increased squirreling problems.<p>Which probably means that I am stuck with the problem until I get a new set of rubbers. :sad: $1K for a set of PS2s that I am unhappy with after only 7K miles... <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/mad.gif" BORDER="0"><p>They recalibrated the SUM while it was there (no charge) and it does seem slightly better for around time driving, but I won't know for sure until I get out on the highway for a road trip next week.

I've said this before (many times now), these tires <B>have to be rotated </B>every 4 to 5K miles. SOONER, every 3500 to 4000 miles or less, if you have lowering springs.

Re: Increased Side Hop + Inner Tire Wear == Alignment Needed? (vizwiz)

No<br>Above average tire pressure will wear out the MIDDLE of the tire NOT the inner edge and besides 38 lbs is not abnormally high at all<br>Were these tires ever on the rear of your car?<br>If not, the only thing that can wear the inside is <B>excessive negative camber </B>(adjustable on the front, to a point) or a <B>way off</B> toe <B>out</B> setting
