Hello gurus! I've got a quick question about tire pressure for my Nokian WR-G2 SUV tires on my 2010 Outback. The dealer recommendation was 32/30 (what I used on my stock Contis). With the new Nokians, though, I've noticed worse gas mileage at that pressure (21-23 mpg instead of 23-26 mpg).

I've got a big trip from Central Valley, CA to Seattle, WA coming up and I was thinking of upping the tire pressure to improve mileage. I don't want to compromise safety, though, considering the gnarly Oregon passes I'll be going through.

Any recommendations on what to up the tire pressure to? 38/36? Or should I just leave it be...

I run 36-38 on my Saab and Volvo on the WRG2s. I am not sure what the safety issue would be. They completely tear it up in the snow. I am getting a set for my '13 this week to replace the Conti's which I will run in the summer.

I run the WRs all year round on the Volvo in the Northeast and get 50k miles out of them.

zero safety concerns. running +5psi is no big deal, I do it all the time, quite common.

I have used many sets but not on the OB. On the variety of vehicles i ran them on I always ended up around 36psi though.

I run 41 psi on my WRG2 tires, In talking to Nokian they recommend 40-44 PSI. Tires maximum rating is 51 PSI. I have found I get better wear, no loss of traction, and gas mileage was better. Fisrt set I ran at 38 PSI and wore the outer and inner edges, which is common on under inflated tires.

Do you keep front/rear both at 41 PSI? That pressure makes more sense considering the tire max of 51 PSI (esp if Nokian recommends 40-44).

Thanks for the feedback!

As long as the wear is even, no issue bumping up the PSI some. I run my MXV4 at 35F/34R which is the same ratio as the door sticker, but much more comfortable feeling to me.

I would suspect that no matter what, the WRG2 won't get as good MPG as the stock Conti's though...the Conti is designed for MPG over all-weather traction, and the WRG2 is designed for traction before MPG.

Actually all of Nokian's tires are designed to be Low Rolling Resistance, the WR-G2 included. If you think about it, it makes sense. Nokian is Finnish. In Finland, the winters are much, much more harsh than here, but gas is also much, much more expensive. So they make a tire that is good at both.

I ended up going with a tire pressure 41f/40r. I leave today for Washington from California. I'll update later how it worked out...
