Hi All, I was getting a little annoyed trying to find #1 - The base wheel and tire specs and found bits and pieces in posts all over the place. Apologies to those who use metric. I still like my british units for some reason - I guess because I live in the USA. Good ole' USA... and #2 trying to find someplace with nice rims errr wheels that also tell us the weights! Found a nice website today while trying to find new rims/wheels for my '05 Prius. First, to confirm/restate the OEM/Stock set. Stock OEM wheel specs: Dimensions: 15x6 (15" diameter by 6" width) Fitting: 5x100 Lugs (5 lug nuts that are 100mm apart) Offset: 45mm Weight: 14.78 pounds Others: 6 spokes Stock OEM Tire specs: Manufacturer: Goodyear Model: Integrity (All Season) Size: 185/65SR15 Serv. Desc: 86S UTQG: 460 A B Weight: 17 pounds The website: http://www.wheelspecs.com Kinda ignore that tirerack/google thingy... and just goto the very top drop down menus. Browse/Wheels works fine and gives wheel weights and stuff. Quite nice. Other sites which you may or may not know of or already have: http://www.tirerack.com http://www.wheelmax.com Thanks to all of you who provided the bits and pieces of information on the forums for the above specifications so that I can shop as knowledgeably as possible. -Cal
