sharing some personal experience, just FYI,

2009 LS460, was using Pirelli P Zero (10k mile old), one tire got a big bubble from hitting the curb, then replaced the whole set with Michelin Pilot Sport A/S 3 (Y), based on good reviews.

After driving it for 1 day (several trips), the major differences are:

AS3 is quieter, softer, more traction, but also has more bouncing, more roll motion

PZero has less traction, stiffer, but car has less roll motion, feels more stable,

will try sell three Pzero tires.

Trading up to the 2007 LS460 from my 2001 BMW 530i, I really notice the float. I think it relates more to the suspension setup than the tires, though. Currently riding on Michelin Pilot MXMs. Strangely, the Michelins are noisier than I remember previous sets - VERY evident on freeway expansion joints. Tire pressures are 33 front/34 rear by my aneroid tire gauge (which are usually quite accurate) but the TPMS reads 36 all round cold and 39/40 hot (spare stays at 36, of course). How accurate are the TPMS sensors?

exactly, I noticed the same. The TPMS number is usually 4 psi above the number I got from air compressor and other tire pressure gauge. my tires are usually 35 cold 39 hot. Is there anyway to re-calibrate the TPMS reading? will try find it out.

Thanks for the info. I'm a few thousand from my next change and the A/S 3 is one of the leading candidates.

I also went through the process of choosing tires among so many options,

basically i looked at the tire reviews from
www.tirerack.com
www.sears.com
www.costco.com
www.ntb.com
etc.

Also I wanted to stay with Michelin.

there are lots of videos on youtube.com, about the Michelin pilot sport A/S 3, that helped me make the final decision.

I also spent some time deciding which speed rating version of A/S3 I should pick. there is the (Y) rating: 186 MPH, and (V) rating: 149 MPH, both are suitable for the LS460, with the (Y) rating being more sporty and providing better handling.

tire shops recommend (V) rating to me. but I wanted to get the (Y) version because it has better reviews on tirerack.com, and because it is supposed to be stronger. Only worry was that the ride may be less comfortable. But to my surprise, the (Y) version tire is very smooth, quiet and offers comfortable ride. I am glad about my choice. LS460 is a very comfortable car to start with anyway.

I have 250 miles on my AS3's that I got from Costco, got the warranty, free rotation, etc, I'm very happy with them, car feels faster coming from the MXM's and far as the Pirellis I've never been a fan of the design. I also went up to a 19" from the stock 18 and gave up a little bit of ride, but not that much, I'd say if your rolling stock 18's and go for the AS3's you shouldn't be disappointed, they are very strong, especially the sidewall. Now, the MXM's have the quietest ride I've see for stock and there also my fav, that's why I'm keeping my stock rims and tires. I think its a personal choice in the end, just good to know I have a warranty on the tires just in case
