Gas mileage!

Says who? I'm sorry if you can't believe that 4 extra psi (51max sidewall) isn't going to cause uneven wear. You will notice an increase in ride stiffness initially, but I'm pretty used to it. Steering response will improve due to reduced sidewall flex. I monitor things closely, I will adjust according to how the tires are wearing. I've been running at max sidewall or just over for quite a while and have noticed less tire wear, and better handling/performance than before. I'm running 245/75/16's Dunlop GrandTrek AT20's.

If you timed me with a stop watch I guarantee I'd have the drivers side wiper back on and in the truck in under a minute. I don't see why you think I'll be in a situation where I wouldn't be able to manage this.

I rarely, if ever, am without cell service. If I go on a trip I can easily put my spare/jack/iron in the back. The approximate fuel savings of .3 from wiper removal, is taken from calculated drag reduction studies done in wind tunnels. I'm not sure why you are so upset.

 

Don't add the clay and just take a ball peen hammer to your truck.

They increased mpg while adding all that modeling clay.

 

yeah remind me to try that on my rusted out 86' cavalier first lol

 

I'm not upset. I'm more just calling you on sheer stupidity, and an obvious disregard for safety.

And if I timed you with a stop watch, the 30 seconds would include finding a safe place to pull over, stopping, getting out, putting the wiper blades on, getting back in your truck, and getting back up to speed? Yeah didn't think so.

Why do you act like getting caught in a sudden torrential downpour could never happen? I know it's happened to me a few times, and I've had to flick the wipers on to "high" just to be able to see.

You do realize that the max psi listed on the sidewall isn't the pressure you're supposed to normally run, right? When towing, you increase the psi as the weight you are hauling increases, up to the maximum psi listed. If you were to do a chalk test on your tires at 55psi, with the truck unloaded (as you typically are), you'll see that you're wearing the hell out of the centers. Especially if you're on P rated tires.

 

I've never been caught in a situation where I didn't have enough time to safely reapply wipers. I cannot think of how that could happen to an observant person.

I have measured tread depth with a dial caliper after 25k miles on brand new tires and there was no difference in tread depth across the tire after running sidewall max from the day the tires were installed. Tires will last a lot longer when inflated this way, since you are reducing heat from friction in the tire as it flexes. Ride quality is another thing altogether. For my wife's Chrysler Concorde, I have Kumho all seasons and Michelin winter tires. I run the Michelins in mid-50's psi and the Kumhos in upper 50's. Tread wear has been nice, not thinning at the center as so many have predicted.

A friend has run 4 sets of Kuhmos on an 02 Infinite Q45. 40k plus on each set. The high performance summer tires. He says, he never had any uneven wear at 50+psi.

Another friend runs at 100PSI in his 80PSI rated E load tires on his 2000 Ford F-350 XLT. He swears by it.

 

Hook set, and landed! What is the purpose of your under chassis sheeting?

 

My 3.4 liter with 32x11.50 tires gets 19.4 mpg

 

You said it wasn't more aerodynamic first?

 

Smooth out the gross aerodynamic drag of course. What are you on about?

 

I've run 50+ psi with no excess center wear for the last 25 years, and greater than rated mileage.

You're out of your element Robb.

 

There's no way it was, i would feel the resistance ramping on the highway, now it glides through the air. it's hard to explain unless you're the one doing the driving.

 

I can admit that logically one might expect increased center wear, it's just not what you find in reality though

 

You should show a chalk test! Not really, but have you done one? Sorry if you've posted it here already I don't like to spend too much time browsing to be sure while at work

 

This is hands down the stupidest gas mileage thread ever! Removing wipers, 55psi in your tires, saving a measly .3mpg...wtf!

You drive a Toyota TRUCK dude. Get over yourself. Buy a Prius, and save yourself the embarrassment of what your writing on this forum.

"O wait, I have to turn around and go back to the house to get.....MY WINDSHIELD WIPERS, and put half a pound of air in my front left or else I'll loose that .3 mpg"


Ahhhh hahahahahaha.

I don't know where you live, or what your gas prices are, but up here in canada we pay more than $1.20 per litre. It's sometimes as high as $1.50 per litre. And you can go through every single Canadian build thread and Canadian thread period. Not once does anyone bitch about gas mileage on their pick up.

As soon as I crossed the border at the Sweetgrass crossing on my way down to Moab in April, I was blown away by the gas prices. I didn't give a fuck what my truck got for MPG's. Every time I filled up in the states, I jammed it right to the gunnels with premium. And even still...3.4L, 35's, 4:10's, all my tools, camping gear, water, jacks, axles....everything. I averaged 550km per tank.

I swore to myself I would never get involved with a gas related thread, especially someone trying to get more MPG's out of their silly little toyota pick up. But this thread, and what I've read in your posts (mikeyjd) is downright and utterly stupid. ITS A TRUCK! Buy an Prius or Honda civic like I did. Problem solved

 

Did you even read the thread? His wipers are in his truck, his PSI is no big deal, and he gets 28 MPG right now and if you read, while maintaining all functionality of a truck. That is why he doesn't have a Prius.

All he is doing is not settling for less, taking initiative and saving money. Did you even read ihs 10 year goal? Engineering companies hire people like him who change things in a positive fashion with little to no downside. They don't hire people who are complacent with what they have and aren't willing to fix it.

He is doing nothing BAD to his truck, the only debateable is the PSI, it sounds like you just want others to stick with you in not caring about MPG because what Mikeyjd did really is a good idea.

I am NOT saying those who don't care about their MPGs are wrong or complacent, just anyone who responds like you just did. You didn't even read. Mikeyjd can argue for himself but you put zero thought into that post.

What's next, don't upgrade your offroading capabilities and buy a Raptor? Don't supercharge and buy a muscle car? Things like this is what TW is for.

 

I don't need a chalk test, I simply measure the wear across the tire. After 30K Michelin's show no uneven wear. OEM Firestones were retired with even wear.

 

So what happens when the wear measures uneven and you've got 30,000 miles of it as opposed to the 30 minute chalk test?

 

You should have stuck with your gut reaction. Why get involved? Some on this thread give a fuck what there MPG is and find it fun to try to improve upon it.

 

No one is waiting 30k miles to monitor tire wear (at least I hope...)

 

To each their own....
