Just ordered a set of Yokohama AVID TOURING-Ss. Someone on a Prius forum I found reported an extra MPG above the OEM Integritys, and I bet they'll be MUCH better than my Wal-Mart specials Douglas XtraTrac IIs I have now.
They're also rated at 51 PSI max, much better than my current 44.

I have used them before. Did 205/75-15's on a '97 Camry for approx 9.25% over size on diameter.
At a mere 40lbs they were firm enough to get 35-36 on the Camry, great wet traction, decent light snow and OK dry traction. They were quiet too.
Inflated to 50 the solid line tread down the middle of tire makes for pretty good LRR tire.
I will be doing 205/70-15, approx 6% oversize from stock 195/70-14's.

What kinds of gains did you see when you switched? My last tank (and first with the new Yokos) surprised the heck out of me, even with some full-throttle acceleration at the local drag strip. I was going to test some intake setups, but something didn't sound right on the second pass, so I called it a day. Even after all that, I got 26.4 MPG. I'm planning on reworking my front air dam to reduce the frontal area and meet with the front undertray, so that could push me above my 30MPG goal.

Nokian is about to release a new model, called the eNTYRE:

eNTYRE Marketing stuff:
Quote:
|
Working from its winter experience, the asymmetric eNTyre features a number of traction and safety characteristics, including 3D sipes, polished grooves and five circumferential grooves for hydroplaning resistance, a “splash stopper” feature to reduce on-road splatter, and ultra low rolling resistance, and a new tread compound for all-season traction and high mileage.
|
Quote:
|
The tire will be available in the first quarter of 2010 in 26 T-, H- and V-rated sizes covering 15- to 17-inch wheel diameters. eNTyre sizes in 15- and 16-inch carry a UTQG of 700AA, while the 17-inch sizes are rated at 560AA.
|
Those are some good wear ratings. Too bad I can't get them in my size.

OK,
results from 649 mile run. 18.03 gallons for 35.8 MPG.
So far I have only installed the front 2 tires. (Yokohama Avid S 205/70-15's approx 6+% oversize.
And this trip included more local driving, 1/2 hr of stop and go interstate traffic and 1/2 hr of right or left lane closed slow downs. Its repaving season.
My RPM's are down. Now when speedo reads 65, actually like 68+ rpms are down to around 2600 instead of 2800.
It definitely took its toll on low speed(60-65) hill climbing though. At 60 rpms get down to below 2400 and it took a lot more throttle to maintain speed.
Sweet spot is at 16-17 tps(Throttle) on level grade at 65-70mph. MAP goes below 8.0, even down to high 6's to mid 7's and mpg on Scangauge hits high 30's to low 40's.
I really need to get the rear tires on, may need spacers, and get to work on aero mods to reduce HP/torque load at why speeds.
Pete

Got all 4 on now...
Back tires clear the bottom on the strut house by about 3/8 inch.
Tomorrow I will embark on a 500-600 mile 2 day journey to/fro work.
Will top off tank, top off tires at 44 front 40 back.
4 hrs of driving at a time I cant take too rock solid tire pressure.

...but what are their LRR "numbers"?
...the stock OEM Goodyear Eagle RS-A's has LRR = 0.0092 value.
...wonder how much better the Nokian EnTYRE's might be?

You mean the coefficient of rolling resistance, CRR? Most tire companies don't publish those, unfortunately.
Also, the lowest CRR I've encountered is 0.006 for Potenza RE92's, 0.0035 for race bicycle tires. |

the only CRR for Nokian I have seen is for the discontinued NRT2 which was the number two tire in the green seal report @ .0085. I hope they have improved since then.
Highest on the list was .0152 and lowest was .0062 Bridgestone B381 185 70 R14
Greanseal's cutoff was .0105. I would say low would start below .009
