smr2112 Report post Posted May 24, 2010 Just curious on this, I am nowhere near needing tires yet....but always want to be informed. The stock tires on the FFH are: Michelin Energy MXV4 S8 225-50-1793V SL Green X / 420 A A / Max Load 1433 lbs.$198.00 (as of 08-17-2009) (from Tirerack.com) -- they have 2 prices for this exact tire/size now - no idea why Michelin Energy MXV4 S8 Has anybody had to replace their tires yet (non-snow) and tried something else on the car?Seems this would affect gas mileage alot. There are a few other "Green" tires out there suchas the Goodyear Fuelmax. While these tires are expensive, they seem to be wearing well and ride well. I am getting43-44/mph now in the warmer weather and do not want to gives this up. Quote Share this post Link to post Share on other sites
akirby Report post Posted May 24, 2010 they have 2 prices for this exact tire/size now - no idea why Simple - they are 2 different tires, most likely different tread compounds as the treadwear rating is different (440 vs. 420). I think the Pilot HX MXM4 has at least 4 different versions - one for Ford, one for Honda, etc. They are all different thus the different prices. If you want to find out which one is the Ford OEM version just put in your vehicle info and it will show you the OEM tire. Quote Share this post Link to post Share on other sites
Stang8URMPRT Report post Posted June 6, 2010 I work for bridgestone/firestone and they offer a free change over when you purchase a new car. I took off the Michelins and put on the bridgestone turanza with serenity. While they are great in dry, wet, and light snow, they did negatively effect my mileage by 2-4 mpg. Bridgestone has a new line called ecopia, which is a low rolling resistance tire, in sizes for all the prius's but not the ffh size. Quote Share this post Link to post Share on other sites

The advanage is not so much the hockey puck ride of the Michelins and quieter due to the slightly higher sidewall but the Continentals are by nature, quieter than the Michelins. If you feel the FFH rides rough because of the sport suspension sway bars, this may be the ticket for you. They are stock on BMW's and Mercedes Benzes. Mileage may drop a little but are $50 per tire less expensive. Do the math for a loss of one mile per gallon, how cost effective are the Michelins then? FMC used the tires to get the high MPG ratings for CAFE stadards so they could sell more Mustangs and pickup/SUV's. Quote Share this post Link to post Share on other sites
