Default 15b of air in the left ft tire = no noise

100% newbie here I have never owned any type of 4wd/awd . I got my first subie in April of this year It had a broke tb its a 1998 6/97 Impreza .got it running and had to put a set of tires on it , I have been chasing a loud wine . I have replaced the rear axle bearings . with no help But I have found out its as quite as a mouse with 15Lbs of air in the left front wheel but with 30 you cant stay in the car . Before I go and spend a lot of money any one been here . coasting its way worse. than lets say going up a hill.

Please take a breath and use your words. Put down the phone and get on a real computer. Use sentences and explain what you're talking about. Out of your garbled mess, I'd ask are all 4 tires the exact same size.....like all the numbers, such as 205-55-16?

hmmmm
so a half flat tire solves the road noise issue?

sounds like a solution to me.
Similar issue with my windshield. Always gets dirty as hell.
I'm removing that lousy thing this weekend.

All tires are 205/60/15's now . There were 3 different sizes when i got it ,and were replaced with a new set. And yes left front at 15 Lb's shuts it up . We don't have many AWD cars in Mississippi so i don't relay know what to do . Of course you can you tube Just about anything and I see a lot of people describing A center diff Bering .

(1) nice. Must have had a smart previous owner. He knew that 3 different sizes is the limit of mismatch for AWD. Four sizes. . . .no way. . .but 3 works.
(2) totally agree on the susposto pop also. No doubt.

Please slow down.
Please use full and complete sentences with punctuation and proper phrasing.
Please get off your phone.

And always, ALWAYS, ALWAYS susposto pop also.

ALWAYS

I'd bet that at a minimum your center diff is toast.

Did you replace the tire that you have running at 15psi as well with the other 3 ?
The reason I ask is you could have a separated tire and with more air in it, will cause the bulge / separation to pronounce itself more.
That is if the noise is coming from the tire, also would think the post above could be correct about center diff.
Subaru has 0/32nds tread life difference policy straight from manufacturer, thats why if you go to most tire shops with a flat tire ( that cannot be repaired ) or seperated tire you are stuck buying 4 new.
So if running 3 different size tires at different tread life's for a significant period of time. There's a strong possibility, you may have an issue with your differential.
