chiming in on the tire inflation thing.... I installed tires for a few years and can state higher air pressure wears on the middle of the tire,, lower to the outside.. with lower profile tires it is slowed some... I also ran higher pressure in my EXCURSION.. Tires were over 250 a pop.. @ 45 psi I was averaging a solid 16mpg.. @ 60 PSI O was pumping out a thrilling 20.. I looked into the fact of replacing new tires and figured @ 44 gallons a tank and 2 tanks a week i could pay for the tires in about 6 months with savings.. Fit tires are so inexpesive it doesnt bother me at all. But i look at it as i went from 14-16 mpg to 38 and over 1000 to remove and replace tires to 300. If you can save 300 bucks before you wear your tires out its worth it.. and thats about 100 gallons of fuel.. so 3 k miles.. But a thought was why does the originator have new tires if he only had 10k miles on the car?

 

Hmmm did you verify that on a Fit Sport like I did?

 

Darn, I didn't break 50mpg on the trip, "only" 46.5 and a couple of 45's.
However, my car was loaded up with 10 computers, monitors, and assorted parts on the way up, and with an ex-employee's garage full of junk on the way back down, so I don't feel too bad. I'll get another chance this week, with a lot less cargo.

On the air vs. nitrogen debate, I figure that air is 80% nitrogen anyway, so it's not that big of a difference (and probably not worth the money). Sure you will reduce oxidation on the inside of your tire a little bit, but so what? Oxidation isn't going to be what wears out your tire-- miles driven will do that.

Barry Would you mind changing your aviator? It detracts to the legit miles to empty at least 3 of us omn here have worked hard for.

 

Sure, not a problem.
I meant no offense or deception by it, just kidding around.

No offense intended.
I just assumed you did not know why some of us do that.
Thank you

 

I did know, but I figured that 677 miles was far enough out of the bounds of possibility that I would get more WTF? responses than anything else. It was also an accidental but real-life picture-- I forgot to reset the trip odometer after my second tank. I enhanced it to make it more readable at that size.

It's about time for a new avatar anyway. How do you like this one? We went to Ketchikan, Alaska in June, and one of the local PD drove his car into the harbor at midnight. He shot out the driver's window to get out; the vehicle was underwater at high tide when he "parked" it there. It's hard to read the sign, but it says "US Government Parking Only, Permit Only".

By the way, I was at 42mpg (car) lifetime at 6400 miles. I just clicked over 10,000, and the last several tanks have been 44+, so I should be over 43 lifetime now. I have enjoyed and learned from reading the posts that you and others put on this forum; I'm getting closer to my goal of high 40's on average.

I have started being less here and more over in a real Eco form. Just too many non Eco, non Fit owners on here taking swipes at some of our stuff. No big deal, but one item I have verified by testing recently and this is for extreme testing.... I have a usable 14 gals in my Fit. We have a few that can and do get +60mpg tanks

So if one really wanted and can get 60 FE thy could get 800 miles

I know one that's capable and may just do that here in the next week or so.

consider using Clean mpg for a log of your FE achievements. If you have records with date, miles and gals you can back fill

 

Just wanted to stir the pot again.

I am at 39k on the original dunlops(sport model) and still rolling at 60psig. I am planning on pumping it up to higher pressures but I think I will start with 65psig, then 70psig, 75psig and possibly 80psig.

 

^^^I guess this is where it stops being about being eco and saving money and more about bragging rights on cleanMPG

Welcome back Mr. pot mixer

Why not invest in some low resistance tires instead of trying to milk those crappy OEM's for any extra 0.05% gain?

 

No bragging here since many others roll at 80psig. I am not sure I want to roll at that high of a psig. 60psig is stiff as it is.

As far as buying some others tires.......well, I will be glad to buy new tires when the time comes. Why spend money on tires when the ones I have are fine?

 

Just saying the OEM's are an ok tire, but not a great tire. I traded them in for credit against my new tires the second day I had the car.

There have been a lot of LR tires coming onto the market that should make a bigger difference in MPG than running high PSI in your stock ones.

 

Holy...60...70...even 80 psi on the OEM tires? Is that...safe? When you have it at such high pressures, are you still able to carry passengers/cargo/extra weight safely, or do you down the air a bit when you carry more weight besides yourself? I guess the sidewall recommendation of max 51psi is bull?

 

haha, safety

 

Hahaha! YES! SAFTY!
BTW, I got new tires last month.

Well, I tried 40 psi front and 45 psi rear. I didn't notice that much of a difference in braking distance. Maybe because I'm on 205 width tires. MPG wise, I'm going to have to wait until my next refill. Well, I guess I can conclude that safty isn't issue when pumping these yoko S.drive up to 40 to 45 PSI (hot temperature).

 

...and where it stops being safe. I get it now, it is just some kind of creepy contest. And, I love all the "scientific" data such as how it didn't feel much different. O.K.

 

-Scientific data is hard to come by since we are not Tire Testers or a tire manufacture.

-Increased pressure yields a stiffer ride, how stiff is relative to ones sensation and liking.

-As far as safety, it is relative as well. I have not noticed any cons on the increased pressure besides the stiffer ride. Breaking is great, cornering has definitely received better traction with the increased pressure and even driving in the rain has NOT decreased traction, some say it has increased but I cannot measure that.

 

I eased mine up to 55 today

 

about time..........still waiting until you hit 60 though!

 

Well, I spent $9 on a digital tire pressure gauge with tread depth gauge.

Tread depth is 6/32 on front tires(didn't measure the back)

Just pumped them up to 65.0psig this morning.

Have 41k on the tires and a patch in two of the tires.
