Tire Upgrade

[Sufferin' Prius Envy]

Consumers Report says you should go with the Michelin X.
Costco say you should go with the Michelin X . . . and $60 off.
Our Mediterranean climate say you will be fine with the Michelin X..

Now why would you want a larger tire? It's a Prius, not a hotrod.

I replaced two of my OEMs with Michelin Xs from Costco. One sidewall was damaged and I didn't want an unbalanced car . . . nor did I want to get rid of two adequate for now tires. I can tell the Michelin tires are definitely quieter.

We replaced ours with Michelin MXV4s and are pleased. The MXV4 is a really quiet tire with ultra low rolling resistance and long treadwear, I have them on the Lexus too. They're pricey, and grip isn't what it is on more aggressive tires with higher rolling resistance (but better than OEM), but I'm pleased with them.

Honestly, anybody who thinks the stock tires are okay needs to drive a Prius with replacement tires. The difference in...everything is just night and day, and our stock tires weren't worn out when we replaced them either.

I double agree! GY Integrities (the OEM tires) are awful. This is the third car I've had with them, and they've been inadequate on all three. They're especially bad when the rain starts. I would venture to geuss that those who claim that the Integs are adequate have not tried the alternatives. I too now have MXV4s installed, and they're superior in all respects, including rolling resistance/mileage. So far (I've had the MXs installed for about 700 miles now), I'm getting about 3 mpg better than I did with the Integs. Ride, handling, and noise are all noticeably better too.

Based on what I've been reading in this thread I've decided to go with the Michelin MXV4's. My area has no snow. Comfort, quietness, & cornering traction is what I'm looking for. I can live with the fact the tires might wear out at 60K. The increased gas mileage is a plus too.

I'm planning on a 4-wheel alignment too. Read some stuff about setting the specs at +.05 degrees of toe in on each side, total +.1 degrees. Any Ideas?

Anyway, thanks to all for the info.

Not to mention mine are worn out at 21K and I rotated them with every oil change too.

I have the stock tires (GY Integrity) with about 16,000 miles on them after 6 1/2 months, and they seem to ride well and have very little wear. Except for that FLAT I got when we drove over a big nail!!! I might try the Michelins when mine wear out. Would they be okay for the midwest, with some snow?

What about Goodyear ComforTreads

I've had them on my 06 for 10 days and I'm kicking myself for not replacing the Integritys sooner. Much quieter with no real MPG hit; I went with the stock 185/65 size.

The stock tires are fine and they're already paid for.

Allow me to differ on that. Last March, on a wet road a woman attempted to make a left turn in front of me, and I was unable to stop the car - it slid about 10-12 feet into her rear wheel, in spite of the ABS. Those tires just couldn't grab enough of the road. I couldn have stopped easily on a dry road. Caused my insurance $3,000.
Then, last weekend I discovered a 3 inch swelling on the sidewall of one of the Goodyear Integrity tires. Took it to the dealer today, and they replaced it under warranty. It was a manufacturing defect.
The service representative said that the Goodyear Integrity tires that are shipped with the Prius are different from the stock Goodyear Integrity tires. He said Toyota ships the Prius with tires that are specially made to be softer than the retail version, to soften up the ride.

Interesting comment about the sidewalls on the Integs. My first experience with them was on an 01 Highlander. When that car was about a week old, I destroyed one hitting a piece of road debris. Seeing it dismounted at the dealer gave me a real shock. The sidewalls on this tire are very thin and flimsy compared to other tires. Shortly thereafter, I had a set of LTXs put on that vehicle, and it too was suddenly handling much better. I'm not surprised at all (though alarmed) that you had such a defect. Yeah I know, business is business, so I see why Toyota puts on these bare minimum adequate tires, but really, I think they could and should do better.
