okaydave Report post Posted March 7, 2013 So is the final consensus that 18 inch wheels affect MPG? Quote Share this post Link to post Share on other sites
tombarker13ffh Report post Posted March 7, 2013 Not so much the wheels, but the tires Ford puts on em. The five-spokers come with the summer goodyears instead of the michelin low roll resistance ones. I bet the effect is minimal though. Quote Share this post Link to post Share on other sites
neod192 Report post Posted March 7, 2013 Many users with 18" wheels reported awesome MPGs, so the 18" wheels don't negatively impact MPGs. The improved handling that comes with the 18" wheels is worth any insignificant loss on MPGs. Quote Share this post Link to post Share on other sites
acdii Report post Posted March 7, 2013 The Goodyear LS2 tires are low rolling resistance tires made for Hybrids, so no they dont affect MPG as you would think being Goodyear Eagles. In fact when the dealer had tested and compared my car to another Hybrid that had the 17" Michelins, they found my car got 1 MPG better. I know if you look back a few months I started a thread questioning this myself, but the consensus is, they dont affect the MPG. I like them and plan to install them on my 2010.

JSKershaw Report post Posted March 7, 2013 I have the 18" wheels (Luxury wheels) and the Goodyear tires. I'm extremely happy with the tires and the handling. I am hitting 44-47mpg regularly on my trips to work and back. I know for a fact these wheels and tires will not effect your mileage. I mentioned in another post, that when it's time to change tires, I will be getting these exact tires again! 1 B25Nut reacted to this Quote Share this post Link to post Share on other sites
MXGOLF Report post Posted March 7, 2013 I have the luxury 10 spoke 18" wheels and love them. The jury is still out on the mileage due to the 18" wheels. Quote Share this post Link to post Share on other sites
Fynack Report post Posted March 7, 2013 I dont think the wheels are the problem. Does anyone know if the ffh has just 1 large battery instead of like toyota where they have several smaller batteries per car? Quote Share this post Link to post Share on other sites
storksb Report post Posted March 14, 2013 I dont think the wheels are the problem. Does anyone know if the ffh has just 1 large battery instead of like toyota where they have several smaller batteries per car?There are many Li-on cells in the battery pack, probably more than a couple of hundred, which combined give the high voltage KWH. I'm sure some one can pull up the exact specs. Quote Share this post Link to post Share on other sites
Code_Warrior Report post Posted March 19, 2013 There are many Li-on cells in the battery pack, probably more than a couple of hundred, which combined give the high voltage KWH. I'm sure some one can pull up the exact specs.I read somewhere the HVB has 76 cells connected in series which would output average about 290 volts. The problem with this configuration is that because they are in series, one bum cell can cause significant performance loss. Quote Share this post Link to post Share on other sites
acdii Report post Posted March 19, 2013 (edited) They may be in groups of series, so that if one cell does go bad, it doesnt take the entire pack with it. In the RC packs they have series parallel packs for some of the larger packs where they need capacity but not voltage. So a 14.4 v pack at 6000Mah uses 5S2P or 10 cells wired in series/parallel 5x2x5. so you have 2 14.4 volt packs in parallel. The car packs may be the same.

Kwerk Report post Posted April 30, 2013 Glad to hear that the 18" wheels most likely won't affect the MPG. Still waiting for mine to get built. Why am I hearing that FFH cars built after March 2013 are better and improved???? Quote Share this post Link to post Share on other sites
