Tire pressure - tire wear

Electric tools are certainly a major strain saver for big jobs. I need them to keep from aggravating RSI (repetitive strain) injuries, not caused by overuse of manual tools. And non-corded versions are both less cumbersome, and not limited by extension cord range, certainly helpful on the farm where the nearest electric outlet may be within 100 feet, or beyond a mile.

But topping off a car tire with a manual bike pump is neither difficult nor time consuming for an able bodied adult, unless they are using the wrong tools. It is certainly much quicker than having to top off an electric device's battery on a charger beforehand.

 

Had to replace a tire months ago due to actual razor blades purposely set up side down on the railroad crossings. The tire company replaced the messed up tire and said the other 3 tires are wearing evenly. I've been told not do this many times but I inflate all tires to 44psi, even during morning summers and they balloon up to 51psi after driving for couple hours in 105 degree temp. People here say it will blow up and bad for tires. I won't get into explaining why it's safe to do that, but not today because I have red wine to finish.

 

The reason I drive a Prius is to get the best mpg's possible, and tire pressure is part of the formula, on a bicycle you want to pump up to the point that you start to lose traction on bumps, I find about 135-140 is good, on a car like the Prius 40-45 is good, higher would be better but comfort comes into play, at 42-40 the car stoppes faster and is overall safer, remember, the sidewall recommendation is 1/2 the bursting pressure,just like bicycle tires.

My bicycle tires have a recommendation of 220psi. Tofu.

 

My MPG never changed after I increased the PSI up to 45. I drove for about 3 months at that pressure. (Michelin Premier tires.) Dropped it down to 42, to reduce some of the harshness. But it was still bad. Lots of clanks and clunks from the suspension, and every small bump was magnified.

Now I'm back at factory PSI specs, and the ride is much smoother. No more teeth-rattling jolts. No more groans from the suspension, and MPG is the same as it always was.

Maybe the trie tread wear will not be as long? I don't mind. That's Ok. A smoother ride and reduced noise is more important to me. And 55-57 MPG is just fine for my needs.

 

Turd gen?

 

Lexus RX 450h

 

Youre comparing tire wear, inflation & mpg from that car to a turd gen? Huge difference, apples vs oranges.

 

First of all I do not have a third GEN.
And second of all, I was just kidding about the Lexus. But I am at the auto show I'm going to look at them.

Here is a picture of Mendel's Mazda CX 5. Beautiful.

 

Hey that's the colour too. Touch up paint is a total pain though...

 

I get batteries for my Craftsman electric hedge clipper and string trimmer off Amazon. 1/2 the price of my now closed Sears store.

 

I would like to know from those who over inflate their tires, exactly what kind of increase in mpg are they getting? Two more MPG? Three more?

And do they have 15 inch tires or 17 inch?

The harsh, firm, and noisy ride that I experienced when going to 42 or 45 psi...it is just not worth it. But I am only talking about my Gen4 car, with my Michelin tires. Factory PSI specs are just fine for it. And so is 57 MPG. (AC on full-time, and using PWR mode, and driving like nuts! )

 

4 gen, use the other forum. This is turd gen.

 

No, it's a discussion about tire pressure, turd.

 

This is turd gen discussion my turd.

 

We will have to excuse grid... He's PWD again. Posting while drunk.
