i switched from 16" rims and tires to 17" rims and tires on my 04 V70... i am running 34psi right now and some times i still hear the tires squeal a little bit. so should i try more or less air.
thanks

Chalk the outer edge of the sidewall (up to the outer edge of the tread) and go out and do some "sporting" cornering. If any of the chalk wears off the sidewalls you need to up the tire pressure a bit.

Could be alignment. Whenever you replace suspension bits you should get an alignment.

you can check the all important details on your tiers there is a sidewall on your tiers which contains a set of letters and numbers of the form AAA/BBC-DD EEEF, where AAA = section width, BB = aspect ratio, C = construction, DD = wheel diameter, EEE = load index, and F = speed rating.
