2008 prius 35mpg whats the point---help!!!

Looks like you may need to Press and hold the trip meter and clear it as well as hitting the reset button on the MFD. I found that out the hard way after buying my prius and rolling off the lot and notice I was staying in the low 33.1 MPGs for over two weeks. After I did that my MPG average started flying up in the 50-60s as before it didn't seem to move at all and I was hybermiling the whole time. But I could be wrong with your situation.

 

Just because I haven't posted here makes my point no less valid, over inflation is. Dangerous Google it.instead of trying to belittle the facts know them first!

Does this tyre look overinflated to you? It'll take a maximum of 51psi - it's pumped up to 37psi (instead of 35 or something). It's a high quality LRR tyre rated for 130mph - being used for driving in town mostly. It's designed to be used in this manner. At speed limits (speed cameras everywhere in the UK) there is no danger. You did read my explanation carefully, right?

You're not being belittled.

As explained, I wouldn't try this on any cheap tyres. I bought the car with cheap LRR tyres on the rear (Old Rockstone's) rated to only 44psi. When pumped to the same 37psi, they'd developed micro cracks all around the rim. They were on the rear and very skittish in use - from over inflation. So I swopped them out for 4 of these brand new. Cost me a lot, but worth every penny. And none of the issues I had with the Rockstones, that compared to these at 37psi, looked like fully inflated balloons, and we're very hard. These still give a soft ride at these pressures (39F/37R)!

Of course over inflation is dangerous. Watch what kind of tyre you do it with and what it's pressure rated to. And how much air you put in it.
Cheap tyres are an absolute no no.

p.s. You're really not being belittled, okay? Just being given actual experience based knowledge, as against urban myths - regarding this particular vehicle.

You do not have to act upon or agree with anything you read on here.

 

Please be more specific about what you consider to be the facts.

'Googling it' will equally produce the facts, the various fictions, and the myths, without necessarily separating them from each other.

Toyota shipped Gen3 Prii across the ocean with 40 psi in the tires. Numerous dealers, mine included, did not reduce that to the recommended level at PDI. I am not aware of any recalls or warnings or adverse consequences from that factory pressure. Some Gen4s are shipping with closer to 50 psi.

 

I don't understand your statement, you have posted here. Otherwise, how would we have anything to discuss?

No one is disputing this assertion. However, making this statement in isolation does not add to the conversation.

What you have failed to establish is exactly what you mean by overinflation. You have left it up to the reader to infer what you consider overinflation. In the experience of most drivers here, the placarded pressures of 35F/33R are too low as evidenced by the tire wear pattern when using these pressures. My advice on this subject is to inflate them to a higher pressure (in the region of 39F/37R) and then monitor the tire wear to see if they are wearing correctly. If not adjust again. Consensus is that these tires get even wear that indicates correct inflation at around the 38F/36R to 40F/38R region.

If you have different data, we'd be glad to hear it.

 

I googled "How do car manufacturers determine proper tire pressure". The second link listed is very enlightening and a very good explanation.

Determining the Right PSI - Tire Review Magazine

Manufacturers arrive at those numbers through negotiations with different organizations and different engineers. After reading this I'm pretty certain we can rest comfortably with our tires that say 51 psi on the sidewall filled to 38 or 40 psi. Some engineers were probably arguing for that high in the first place but had to compromise on a lower number with those people in favor of softer rides. Under very specific circumstances they even recommend going all the way to the pressure printed on the sidewall!

So no, a little over the manufacturer's door jamb pressure is not dangerous.

 

traction batter weighs 125 pounds not 1000 and if rebuilt correctly is as almost as good as a new one for 1/5 the cost..no one with any common sense puts a brand new battery in a car that's almost 10 years old with over 200,000 miles..

 

You don't seriously believe that do you?

A rebuilt, esp Gen2, is NEVER as good a new OEM HV Battery. A rebuilt will work, but for how long? A new OEM HV Battery will likely have a lengthy trouble free service life of 8-10+ years, just like the original. Yes, some original OEM HV Batteries have failed prematurely, but those numbers are small. How often are people posting about their failed rebuilt HV Battery pack here? Seems quite regular, just as the sun comes up once a day.

Yes, each person makes a conscious decision based on cash on hand, or lack of it, and long term plans for the car to go DIY /rebuilt/Doorman/Fraudtech(Greentech) vs new OEM HV Battery. One should not expect a rebuilt to give the same trouble free operation and longevity as a new OEM HV Battery.

What if the person has sufficient DIY skills to:
1) move the new OEM HV Battery pack into another Gen2, to replace the current Gen2, should a cost prohibitive repair occur or a vehicle accident. A replacement Gen2 can be had pretty cheaply.
2) move the modules from the Gen2 HV Battery case into a Gen3 battery case. The Gen3 will have a longer lifespan b/c they are younger than Gen2.

You weren't considering these two scenarios, and now just might reconsider.

 

4 years ago I rebuilt a battery pack in my neighbors 2005 prius,they have never had a problem since and put over 40,000 miles on the car..I have rebuilt the battery in mine years ago and never had a problem..why would anyone spend over $3000 to buy a new battery for a 12 year old car worth 3500? but you waste your money any way you see fit

 

Beachbummm- It's not wasted money any more than buying insurance is wasting money. Should our current battery need replacing it will be replaced with an OEM one.

Despite your 2 anecdotal examples, failure rates are much higher on rebuilts and refurbs as compared to new OEM units, When we're on our annual trips away from home (we cover the country from CA to NC and the west coast from L.A. to Seattle) we want to be driving with confidence in our car.

Our Gen II is eventually going to be passed on to one of our daughters as a first car, one she will most likely be depending on to get her to college in another state. A hybrid battery with a 10 year failure rate of less than 3% is important when it's headed across the middle of the desert with your daughter alone in the car, making that OEM battery well worth the extra money.

OEM or rebuilt varies based on each individual circumstance.

 

That is right. We will spend our respective resources (time & money) as we each see fit.

I don't know where you get $3K+ for a new OEM HV Battery. $2071 + Tax ($186.30) = $2257.30, at San Bernardino or North Hollywood Toyota. Just need to get the service manager's approval for OTC (Over The Counter) sale.

I place a premium or reliability and unnecessary maintenance. For me, $2257.30 is a small price to pay to achieve trouble free operation of the HV Battery.

Granted a new HV Battery is relatively expensive. But it is far cheaper than having to buy a new car or a younger used car. When your car needs tires, do you balk at the cost of new, or do you buy used? Most people buy new, probably b/c of safety and longevity concern. Yes, the cost difference of four tires is cheaper than a new HV Battery, but both are consumable items. Again, we will each spend our resources as we see fit.

That is great you are going on 4years/40,000miles on one of your rebuilds. Don't forget, if a module needs to be replaced today, you are looking at stock that is 7-12years.

What about the fact that a new Gen2 HV Battery is portable directly into another Gen2 or indirectly into a Gen3, not a slightly compelling reason for you?
