80831 Miles on Original Integrity Tires

[MT-IL]

Today is the magic day to swap out my Integrity tires. I have 80831 miles on the originals. The car is just days past 2.5 years on the road.

My lifetime is just a hair over 50.2mpg. I was going to hold off until closer to winter but discovered a screw in one of the tires when I went to the car today.

I guess I can be happy to go over 80k on the originals. Hope the next set gets me close to that as well.

It seems Discount Tire is going to take the full 2 hours they figured it might be. I hope they are done before my laptop battery gives up.

OK. No need to leave us in suspense:

Obviously, you drive many miles per year, so most of these miles must be highway?

What tire pressure have you used?

What replacement tires are you getting? (name/number and size, also -- please!)

Congrats to you!

Most of the miles were Chicagoland tollway. For the first 75000 miles I had a 130 mile per day commute. Now I'm down to about 35 a day.

I run them about 38psi, sometimes 40ish. I rotated them at 10k, 20k, 30k, 40k, 55k and 70k miles.

I'm putting on the same tires again. It would seem 1:45 to 2 hours at Discount tire is giong to be more like 3 hours. Maybe they serve breakfast if I'm still sitting here in the lobby when the sun comes up.

I planned on finding my best deal before swapping them. I feel like I may have gotten my "Best deal today" but wow have I been sitting here a long time. If not for the screw in the one tire, I'd probaby have made about 83k or 84k on these ones, then changed them out for winter.

They're pretty worn out, but still good if not for the screw sticking out of the one.

I would love to see pics of the tread at 80k. Must be pretty ragged.

Wow! You did better than me. I only went 3,328 miles before I got rid of my Integritys.

Of course, it snows here in Idaho, so they weren't much good to me.

I was thinking the same thing. I was picturing white string showing all around where the tread should be. LOL.

I salute you for your bravery.

You must have driven on roads made from marshmallows.

You win the award for most miles logged on one set of Integrity tires, congratulations! I replaced those tires after 15K miles. It is fascinating to contemplate the very wide range of tire treadwear life experienced by Prius owners.

Consider the wide mpg range reported on GreenHybrid: as high as the 70's, and down to the 20's.
Hybrid Mileage Database - GreenHybrid

Given the wide variability experienced with tire treadwear and mpg, I am wondering what variability will be demonstrated with traction battery life, now that the first 2G are approaching 5 years of age. I don't believe it is realistic to expect that the 300K mile life experienced by a handful of taxicabs will be realized by most Prius - that is like looking at Edna Parker who is 115 years old, and expecting all (or most) American women to reach that age.

Well, 300,000 taxi cab miles doesn't really equate to your average joe's 300k miles for sure. They are extremely hard miles.

Hi Brad,

I do not agree that your statement is correct relative to the traction battery. Compare a taxi being driven 8 hours a day, 5 days a week to a very lightly-driven privately-owned vehicle. The taxi duty cycle may be much better for maximizing traction battery life (as measured by the odometer), compared to long periods of no use. One reason for traction battery failure is electrolyte loss - this is more likely to happen as the module seals age over time. So a usage pattern where a taxi logs many miles over a short time may be more advantageous compared to a privately-owned vehicle logging relatively few miles per year, over a much longer time period.

We're seeing the occasional Classic traction battery failure being reported with a US population of only 53K units (see the Classic subforum for details.) The 2G battery design has been improved, but the 2G population is several hundred thousand units, so it will be interesting to see what happens in the next couple of years.

300,000 miles is rare FOR ANY CAR FOR ANY REASON...

its funny we talk about the traction battery lasting 150,000 miles and being inadequate somehow...

when we look at the other benefits of the Pri, less gas, less pollution, less brake maintenance, less engine maintenance, etc...

there have been reports of traction batteries being replaced under warantee after 30-60,000 miles, some after at 100-140,000 miles... but that is par for the course. we are not driving perfection (ya that's right, perfection HAS NOT BEEN INVENTED YET!!)

what about things that other cars suffer from?... im sorry, but knowing all that i know after 4+ years of driving a Pri, i wouldnt have done a thing different....

other than a PHEV or an EV, there is no other car in the running for me for general passenger use besides the Pri.

anyway... back to topic,

im approaching 32,000 miles on my OEM tires and am nowhere near replacing them. im guessing probably 50-60,000 miles or so. this being my 2nd Pri, my first had 31,000 on it before it went away with tires showing only slight wear as well
