Another Prius Tire Question

it depends on the tire unfortunately. there aren't mpg specs for tires, and i've seen anywhere from 3 to 10. but that's anecdotally, based on owners observations.
i would read through the tire threads and select on based on your parameters

 

I have two Prii both 2008. I’ve tried several different tires. I have gone back to the gold standard for all season tires. Best fuel economy comfort a ride quality
Bridgestone Ecopia 422 plus. best deal is Amazon $130 each ship to you. $600 4 tires including tax. Then $100 for mount and balance at your local Walmart. $25 per tire.
$725 and your done. ROTATE every 2k miles for best wear. Crap tires will be $500. These are most expensive but safer, better, quieter.
My Family is worth it. I ran these for about 5 years in Colorado and now in Kansas.

 

Getting ready to buy a third set for my Wife’s Car

 

My Altimax RT43 cost less and have better tread, traction, temperature, and speed ratings than the GY Assurance or the BT Ecopias I ran previously.

I did not notice any noticible drop in the mileage from the LRR tires and love the improved traction in the rain.

 

I run the recommended pressure from inside the door.

I can't speak for your car, but mine is quiet, and tire noise isn't an issue for me.

Your ears may vary.

 

The prior owner of my car put larger tires on my touring that are also not LRR. They are cheap Nebula Pioneers (whatever those are). I have never drivin my prius with LRR tires, but I cannot imagine getting much better fuel economy, especially with my tired old battery. I regularly cruise flat ground over 50mpg on the display, and highway trips around 70mph I average 46.

 

One problem trying to answer, the LRR labels are near meaningless: so-called LRR tires rolling resistance can vary, a lot. Some with label can actually be worse than some that make no LRR claims. You have to take tires case by case, read reviews.

 

Did you mean 20k? I can't imagine anyone rotating tires every 2k. That would be extreme overkill.

 

The whole LRR thing seems like marketing nonsense. As other have said, a LRR tyre doesn't necessarily give better fuel economy.

In Europe, tyres must have a sticker that shows fuel consumption and some other properties so you can see at a glance which ones give the best mpg. For example, a Goodyear Vector 4Seasons is A-rated for economy and B-rated for noise, so it's probably a good choice for a Prius:



You don't have anything like this in the US?

It's a bit obsessive alright

 

Another vote for General Altimax RT43. There's an RT45 now, so you may find a deal on the earlier model.
I don't get the concept of low rolling resistance. I want a tire with good traction. Can a tire have both? To get one characteristic, I think, you generally have to give up something else.

 

Yes. I meant 2K. I have all the jacks and pneumatic tools to rotate myself. I have it down to 20 minutes to do all 4 tires. During the pandemic I was delivering food to pay the bills. And by doing so I was able to maximizes tread life. I was putting 150 miles a day minimum on the car. So I did oil changes and tire roaring myself to save more money and maximize profit. I just kept it up after I got a new job and life returned to normal. Now it’s every 7 months to a year but I still do it. Just what works for me.
