Hi all, newbie C-Max Hybrid owner here. My first experience with a hybrid ended abruptly in 2009 why my 'silverfish' 2005 Prius got the dreaded 'screen of death' The two Toyota dealers in Tulsa both told me to 'walk 'til we can look at it', (a week or ten days out), so I headed to Ford. ended up with a 2009 Fusion SE 2.3 that was a decent car....fast forward...so was the 2012 Focus SE, but after a trip to Scottsdale in early December, the wife decided it was time to get an 'upgrade'. Searched Ford and found one new SE white over black cloth, and not another single C-Max closer than 300 miles. Certified Used produced two vehicles, a 2014 SE in Witchita, Ks, and a 2013 SEL in Stillwater, Ok. No doubt the Ice Storm SEL Pano was the choice, bought it over the phone, picked it up Dec 24.
Now for the tire pressure issue. Has anyone read the NTSB Ford Explorer/Firestone Tire report? Ford specs for the tire and tire pressure on the 1998-2001 Ford Explorer were a perfect match for disaster all in the name of ride quality. Jaques Nasser personally falsified the vehicle weight when presenting the specifications to Bridgestone/Firestone engineers who argued the tire needed more capacity AND inflation. Firestone had been asked to remove 18% of the shoulder tread which compromised the carry capacity of the tire. At recommended pressure (26 psi), a Ford Explorer with 325 lbs of passengers in the front seat, 42 lbs in the left rear, would experience catastrophic tire failure of the left rear tire at ambient temperature over 86 degrees, traveling 70 mph continuously, between 42-54 min.
Tire experience I have had on recent vehicles: 2005 Prius, came with Goodyear Integrity 15" tires. Junk and replaced them with set of Yokohama Avid all season at 8k. Yokos going strong at 35k when traded, ran at 45psi. 2009 Ford Fusion had Continentals that got noisy, but held 45 psi quite well, made 25k miles with even wear and anticipated life near 40k. 2012 Focus wore Continentals smooth out at 20k, running 45psi. Replacement Bridgestones got noisy at 25k, but showed little wear and two were replaced under warranty just before trade. Also ran 46-48 psi in these with no trouble. 2009 Ford Flex with Yokohama Avid Ascent Blue Earths that have 40k on them at 40 psi and still have 9/32nds tread on all four, even treadwear, silent operation. Running 42 psi in the Michelins on the C-Max, and even though this was a Hertz rental unit in a previous life, all four tires have even wear and 8/32nds at 25k miles.
Happy Motoring, all....
