What is the factory spec for the OEM 2004-09 S2000 (AP2) 17-inch wheels, 17x7 front / 17x8.5 rear on a Honda S2000 (AP2, 2004-2009)?

Q: What is the factory spec for the OEM 2004-09 S2000 (AP2) 17-inch wheels, 17x7 front / 17x8.5 rear on a Honda S2000 (AP2, 2004-2009)?

Factory specification. Factory AP2 wheels: 17x7 front and 17x8.5 rear on 5x114.3 with 215/45R17 87W and 245/40R17 91W tires, every year 2004-09 (Honda's 2004 and 2008 sheets and the 2004 and 2008 manuals); wheel nuts 80 lbf·ft. The +55 / +65 offsets come from reference sites and an enthusiast guide, since Honda prints none, so the row stays at tier 2. The CR uses the same sizes with a 255/40R17 rear (F-ap2-02).
