Time to replace the Bridgestone Potenza RE050 original tires on my '03. These are supposedly the extra load tires.

The '03 OE tires are specified as:
Front: 245/45ZR18 (100Y XL, 800kg/1764# @50psi)
Rear: 265/40ZR18 (101Y XL, 825kg/1819# @ 50psi).

Bridgestone's own selection guide on its website says that the OE tire is not available. Hmmm. Seems strange. I can find a spec sheet that shows my tires, but that could be history.

Michelin shows Pilot Sport.

Goodyear has nothing.

TireRack recommends the lower-rated load factor Potenza RE 050 product.

What are you folks using now on your S55 (2003 or later)?

Thanks anyway.

Pirelli doesn't seem to have a load rating that matches up.

I put the new style Pilot Sports on my car - I don't like the rounded shoulder of the new style Pilot sports but they sure are a lot stickier than my original Pilot Sports. The asymmetrical tread pattern is neat too, they look bald when you put them on. I got them from discount tire.

Also Bridgestone makes original size tires for the front and rear, but I really like the new michelins - damn are they sticky!
