what toyota said about tires

I run mine about 40... 38.. maybe 41...

Have 58,600 miles on the originals and heading to about 70k before I think I'll have to change them out.

So far, so good, so safe... I can't recommend or tell you what to do, but I've been doing well on them with this 'closer to tire spec max' than the original toyota 'spec'.

I routinely take a 500+ mile trips on the interstate each way and run at 42 front 40 rear on the stock Goodyear Integrities and so far no problems whatsoever, no visible wear problems either. It does make for a slightly rougher ride, but even at the "recommended pressure" the Prius is not very gentle.

 

I take my car in for oil change every 3000 miles and have the tires checked and rotated like a good little do-be. My tires lasted 25,000 miles I was sure glad they had ExtraMiles warrenty on them. I don't know what brand they where but I did expect them to last longer then 25,000.

HarperLee,

It's Boo. And I also own a 2007 Magnetic Gray Prius Package 2 (sometimes called Package 3 or other number depending on where and when you are on the Toyota website). Guess the apple doesn't fall far from the tree.

I think you know that there are a lot of threads and posts on PriusChat regarding the best tire pressure for the Prius tires. But if you don't, then you should check them out. They are all in line with the replies you've received so far.

Specifically regarding the "dangerousness" aspect of the different tire pressures, I don't think that's a factor for either the factory recommended tire pressures or the higher "PriusChat" tire pressures or the points in between.

A more important issue regarding "dangerousness" is the experience that a lot of PriusChat owners seem to have had with the OEM Integrities themselves -- they don't seem to handle well under any conditions, and seem especially dangerous in rain, snow and ice. There are numerous posts here about skidding, sliding, and hydroplaning with the Integrities. A lot of PriusChat members replace their Integrities (even if they're brand new or near new) with better rain, snow and ice handling tires like the Goodyear Assurance TripleTred, Goodyear Comfortred, Michelin HydroEdge, etc. I, for one, am getting the TripleTreds installed this week, even though there are only 1000 miles on my Integrities.

Still looking out for you after all these years.

There are many different points of view. I am very suspicious of alarmist statements. According to Goodyear your tp is in spec. IMO the only thing in danger when running a higher tp is the profits of the tire salesman. Harder tires last longer and provide higher mpg. In all honesty I need to develop the habit of checking the tp before leaving the dealer's lot. The only time I found my tp low was after a trip to the shop.

45psi works for me. Inflate the tires to provide the combination of ride, handling & economy that you are happiest with.

Well said, Jim.

The tires last longer, run cooler, are more efficient, and HANDLE BETTER, IMO.

Take a close look a brand new Integrities and you will find that the center grooves of the tire are about twice as deep as the grooves at the edge of the tires. Therefore if the tires were to wear evenly across their surface, the edges would go bald long before the center.

I think all these people who report "excessive" edge wear at 25-30K miles never paid attention to the relative depths of the grooves until the point when the edge grooves were getting obviously shallow. They then look at the difference in depth between the edge grooves and the center grooves and assume the difference is due to uneven wear, rather than the fact that they were manufactured that way.

I don't know why Good Year designed them this way, but they did. If you don't believe me, just take a trip to your local Toyota dealer and look for yourself. Or look at your existing tires with the "excessive edge wear". You will notice that there is a drop between the bottom of the edge grooves and the bottom of the center grooves. If the grooves had all started at the same depth, then the bottoms of the edge and center grooves would all be at the same level with no change when you move from the edge groves to a center groove.

 

I just bought 2008 Pruis with 17 inch wheels and low profile tires factory installed,,looks great...anybody have the same and what tp should they have?
