Hi ,
doubts about tires' pressure
bought these goodyear eagle GT+4 255/60/15 . OK , there's better stuff on the market, but the availability of tires with white letters here is quite difficult ( and price was fair for my tires)
can't find any spec about correct pressure ( nothing written on the tire itself and nothing on the Goodyear website). So I'm referring to my car's specs on the door. But I suppose that I'm making mistakes with the pressure choice.
Help please
Aldo

Hi Texas Jim,
yesterday my mechanic put in place the new spark plugs. The old sparks were OK , the problem was : 2-3 were slightly loose ( those that are more difficult to reach ). Infact I supposed that something was wrong with sparks.
Oh my god , what a difference with new sparks! Above all at low-mid rpm. now my engine runs so smooth...It desn't smoke anymore and I'm sure that the gas consumption will be improved ( good). less noise too. Instead I don't see a great difference at high RPM : but I must probably go for a larger air cleaner ( now mine is 10"), to have more air flow when the carb demands .
before replacing the last spark plug , my mech measured the compression ratio. He had some difficulties in keeping firmly the meter in the spark's hole ( due to high pressure) so we supposed that the actual compression ratio is slightly more than the value measured : we have measured 9:1 . But we think it should be about 9,2:1 . Does this value tell something to you about my engine HP?
power steering . I hear a hissing noise in the play position ( with engine OFF) coming from the control valve. No noise if I go over the play position.
I have checked the gear box watching it through the engine bay( from above): I see the shafts and levers moving without any play there
Set all the 4 tires at high pressure too
thanks
Aldo

383 Crate motor - origin unknown - I think it is safe to assume a 9.5:1 compression ratio, that's pretty standard for a crate 383 that runs on pump gas.

RE: Tire's pressure ?
DeeVee,
Is the Max pressure for the GTplus4 44psi for the 225/55VR16 only or for all GTplus4s reguardless of the size?
If it's 44psi for the 60/15, I'll be calling Shine Bros. and blowing out the guy who gave me the "wack" info.
I went to "Tire Rack" which I'm familiar with but only see the 225/55VR16, like you posted. When I clicked on "specs" I got only the one size. Aldo's tire is a 255/60/15.

RE: Tire's pressure ?
My Goodyear GT II's were 44 PSI as are my Firestone Firehawk Indy 500's - both are 255/60/15's. I agree withTexas Jim'scomment on that being the only size posted on Tire Rack, so I did make an "assumption" based on that information as well as my experience with my own tires.
Now I fully expect that you guys will give me the Benny Hill version of what an assumption is.....

RE: Tire's pressure ?
DeeVee,
Where did you get the info for 44psi for the 15s? Or is the 44psi the assumption you made? I'm not doubting your info, just wanted to know where you got it. Like I had said in another post, I had Firehawks before the Good Years I have now and they were 35psi.

RE: Tire's pressure ?
Nah, that's too easy. 
Didn't know that it originated w/ Benny Hill tho. Learn something new everyday. 
BTW, my old original Eagle GTs (early 80s)state 35 psi max on the sidewall.
