initial mini review of new nokian WRg2 tires

Thanks for the review. I'd be interested in hearing if your mpg improves over some time. May be my next choice in tires down the road.

 

How about tire noise?

Watch for an odometer slight over-read, as the tire's RPM is 849, while stock Integrities is 855.

 

I'm glad that I wrote "slight". Heh

 

I am also interested itn this tire. Try running the tires at 42 /40 and see if the milage improves. FishHawk

 

That's good news. These will be my replacement tires when the stock tires ware out. FishHawk

 

I have had my Nokian-WR tires for a little over 5000 miles, and just recently pumped them up to 40/42 PSI. My mileage is back to 50 MPG, same as with the original tires, and I agree, the Nokian tires are Great! Mine ore the older version, not G2

 

"also as for the difference in revolutions per mile, the diameter of the 185/65/15 tire is 24.5''. a difference of 6 revolutions per mile means a difference of 12.25 ft.

there are 5280 ft. in a mile, so the tires will actually roll 5267.75ft. that's 99.7% of actual so at 60mph, you're actually traveling 59.82mph. a negligible difference."

If I recall geometry correctly, you need to multiply the diameter by Pi, or 3.14159 to get the circumference. So, six revs would transport you 38.5 feet. (Still fairly minor).

 

so you very happy with the tire? for us prius owners how long you expect that tire to last until you have to replace it again? if it can get 3 winters out of them then that'll be pretty good!

 

I purchased my WRG2's this spring, have 3300 miles on them and the treadwear indicator is already missing the 8 (4-6-8). Perfectly even wear, alignment was checked at installation. Car handles great, summer mpg's are easily in the +/-50 range, but don't know why they are wearing so quickly?

 

Because they're a soft compound designed to work in very low temperatures. The WR is a winter tyre, not all-season. In summer the compound gets too hot and wears quickly.

Nokian make summer tyres as well. I'm going to try out some 'H' tyres (seriously, that's what they're called, simply after their speed rating) because after 21,000 miles, the OE Bridgestone Turanza ER30s (UK model) are worn out - down to 3mm tread on the front. I would try the i3, which have had good reports from US owners, but Nokian don't make them in 195/55 R16. (They're good for the 185/65 R15 size used by the 'base', non-Touring Prius.) The i3 is T-rated (up to 118mph) and are plenty for the Prius.

Nokian are working on ultra-low rolling resistance tyres: Nokian Tyres - Summer tyres - Winter tyres - Friction tyres - Studded tyres

 

Nokian WRG2 Update-
I have only 17,100 miles on my WRG2's, still handle great but wear indicator is down to 4 and under (8-6-4) already. My Nokian Hakkapeliittas, a soft tire for winter have 13,000 plus miles and still have 6 on the indicator, seem to be wearing just as well or better...I figured the WRG2's would go longer, will look for less soft tire for summer next time.

(just put on my Hakkapeliittas for the first snow of the year and it's like I have all wheel drive! All I need is a lift kit and I could go through anything)

 

Craig, if you like the Nokians and want to stick with them then look into the enTYRE or i3. Both are great tires. I've ran the i 3 and really liked them. For the money there may be better options with longer treadwear.
