Michelin EnergySaver A/S tires at Costco

I would consider getting the 195/60R15 size -- better and safer handling and braking, plus at TireRack, they're $7 less per tire than the OEM 185/65R15 size.

 

Yes, 195mm is the width of the OEM Touring Prius tire and 185mm is the width of the OEM Standard Prius tire.

Using Miata Tire Calculator's assumed tire rotation values for different tire sizes, the 195/60R15 would result in a 1% over-read, meaning when the speedometer shows 60 mph you'll actually be traveling 59.4 mph. No big deal.

Personally, I'd gladly trade that very slight speedometer over-read (and probably less mpg because of the wider width) for better and safer handling and braking any day of the week.

 

I also noted that the tred wear index of the EnergySaver A/S is a LOT (almost half) lower than the Hydroedge (or X-Radial). 480 vs 800 (or 740).

 

Wouldn't a higher treadwear rating mean a harder compound, hence a harder ride.

My Bridgestone Ecopia's have a wear rating in the 300s, and running 42 front 40 rear psi, I wouldn't want the ride any stiffer.

 

The compound of the rubber doesn't necessarily mean a "stiffer" ride, it could..., but the construction of the sidewall along with the compound usually changes the ride. The original Goodyears on my 07 are very soft on the sidewalls, even at 42psi, and the construction of the tire makes it very rounded from the tread over the edge of the tire to the sidewall. Goodyears wear very quickly on the edge of the treads when cornering and if the pressure is just a bit low. Michelins have a flatter tread pattern and stiffer corners of the tread. They help control during cornering and stopping. The HydroEdge tires are good and stiff (Much better handling on a PT Cruiser) and don't wear nearly as much as one with a 480 rating. I'd opt for the higher number for longer wear!

 

Please explain more about tread wear index, I want to buy the tire that last longer so which index I should buy?

 

There's not much to explain. The higher the number, the longer the treadwear. Theoretically, a tire with a treadwear rating of 800 will last twice as many miles as one with a 400 rating.

 

Thank you Jay_man2, That much much easier to understand.

My stock tires last for 62K. I just replaced with Michelin X Radial less about two weeks ago. I love these tires because it much better handling, better or same MPG (54MPG).

 

Hi. I went to Costco to replace my stock tires today. I was going to get Michelin X-Radial DT P185/65R15 ($105.99 each plus $15 installation per tire; $70 coupon can apply and will be end tomorrow by the way). Then I realized they are having X-Radial DT P195/65R15 for $94.53 each. I thought it's a better deal since 195 should be more expensive than 185? So I ended up getting those 195s on my Prius!
I see people here do suggest 195 but go with 60 instead of 65. I am wondering does that make any differences?

Thanks,
Jason

 

I believe the key is COSTCO! I put Hydroedge's on at Costco and after 25K I had a screw go from the bottom through the sidewall. Costco replaced the tire for $13.50 under there road hazard warranty. I was impressed

Did I misread the Yokohamas, that they have a max pressure of 44 psi? It tires are max rated at 44 and they are inflated to 42/40 what potential safety risks might we be adding to our drive? --TK

 

In other threads they mention that the 44 psi max is a load rating, etc. etc., and discuss burst pressures, members running psi's in the 50's, and things like that, but there's no mention of any real safety risk.

With 42/40 you may increase the harshness of the ride, may increase the stopping distance, but that's about it from what I read and personal experience.

 

Jay_man2, Yeap, there has to be some safety factor reduction between load rating, the max pressure stamped into the sidewall, and burst pressure. I've always stayed away from the max pressure, maybe because I can't tell the ride and handling characteristics differences 3 to 5 psi makes. Add to my tire insensitivity that this is my first Hybrid and first LRR tires and I'm really in the deep end of the pool. Thanks again. --TK

 

Do I understand it correctly that there is no mileage warranty on these tires?

 

I just replaced new set of tires again at 162,000 Miles so the Michelin X Radial last 100,000 Miles (rated at 80K miles).

 

Max pressure is at max load too. Not many are running max load are they?

 

i think most of us are singles, except uber drivers.
