Recent posts about a Prius weighing in at 1940 lb on a truck scale are interesting. The following conjecture may hold the explanation for the 1000 lb discrepancy: Truck scale is calibrated within one percent tolerance at 100,000 lb. Tolerable error is 1000 lb. QED. Bob Smith

What! Our are calibrated to the nearest 100. Not sure where you obtained your info. D

So if "curb weight" is different from the type of measurement you are doing, that means that *ALL* vehicles measure differently. In other words, it doesn't matter what number you actually come up with, Prius is still heavier than average regardless. Heavier than average means the tires will naturally wear out faster than average. JOHN http://john1701a.com

What does "heavier than average" exactly mean? What are you comparing this car to?

Are you refering to another vehicle that uses the same size tire weighs less than this car? Please be more specific in your statement.

Besides the tires do not wear equally on both sides. With the other two Pruis owners I know the tires wore on the drivers side faster than on the passenger side. My tire on the drivers side blew first. The front tires wore faster than on the rear. I would like to know if anybody has noticed the same type of tire wear? John, I believe you work for Toyota!

> John, I believe you work for Toyota! Over the past 3 years, I've tried my hardest to make the technology I strongly believe in a success. The fact that currently only Toyota is using it is causing your misunderstanding. Just take a good look through my website, it was built by me, an over-enthusiastic computer programmer with a passion for digital photography and a desire to prevent damage to our planet. If you were to take your tire concern to the GROUP instead of here, as we already suggested, you'd get the feedback you desire. Someone could just as easily conclude that you work for a Detroit automaker who would rather not see this hybrid technology become a success. Think about it. I doubt you are. But since we have actually encountered people with that intent, the possibility can't be overlooked. Participate where the resources are, on the GROUP, not here... http://autos.groups.yahoo.com/group/toyota-prius Then you don't even have to wonder about my intent. Others can help you instead.

Thanks John!
