Fustrated with tyre pressure...

[huhjared]

ok the story goes like this...
was complaining that my tyre noise is loud on my euro and everyone here thinks its because of my tyre pressure... ok accept that went to buy a tyre pressure guage from supercheapauto and being a cheap ass i bought a pen style one (metal) apparently the better ones among the cheap ones for $7/$6.99...
went to the servo to check my tyre pressure... ok pumped 32 ( as recommended for quietness) then used the tyre pressure with the pen... ITS 36...
confused as it is... went down to pump it to like 28 and it shows 32... to be on the save side... i pumped "32" from the servo which equates to 36 on the pen drove home and checked my neighbour's tyre perssure which is a new corolla... it shows 32... i am like dont think a new car with 4000ks be wrong would it???
which should i trust? servo or pen? if its the servo wont that mean that i was on 40psi for the past 2 weeks??? and that wont be true as the guys who fitted my tyres check over the pressure when it had 40psi and said its all good...

confused confused... going on a long trip to Gold Coast tom morning and wont want the tyre pressure to be wrong eating my rubber on such a trip especially when its spanking brand new...

reason for all the frustration:
just gotten the 2nd hand euro 4 weeks ago and it was supposed to be a comfy car especially when i gotten the lux version... it is embarrassing when people sit in the car and ask why is your "new" car so noisy...

The pen pressure gauge is CRAP. Return it for a dial pressure gauge instead. The Corolla's pressure reading is useless for your comparison.

lol dont buy them pen things.

[huhjared]

pffff.... yeah the thing is i spoke to him regarding his tyre pressure and he said its on 32 on his corolla... so wont that be like a standard to follow on the gauge? what about the digital pen one which is like $20 at the warehouse... saw its like $9.90 today when i went there...

[aaronng]

Stay away from the digital shit too. I bought one and it stopped working within 6 months. The dial type is the only one you should trust. I bought the $11 Aunger one from BigW, and when I compared it to a calibrated gauge (complete with serial number and all that shit), it was off by only 0.5 psi! It's been 2.5 years and it still reads as good as when I bought it.

[itshk]

try another servo

[huhjared]

I bought a dail tyre and i broke in like 2 days... hahahaha... paid $9.99 for that... the needle inside popped out... arh... anyway could you say whats the difference between your dial gauge vs the digital gauge at the servo? if you pressed like 32psi on the servo what would be be roughly reading out from your gauge?

[Crapdaz]

go to a local petrol station (not the big name petrol stations), they will have a manual air gauge pump so you can see the proper reading.

i never use the automated sh*t, trust the manual stuff all the way.

What tyres are you running?
and does it sound like your tyres/road noise(humming sound) or suspension (rocking)?
Have you checked whether or not you have rocks stuck inside your tread?

[huhjared]

humming and bumpy... so i guess its due to the high tyre pressure...

I've been driving my Dad's Euro lux for the past few days! Heaven I tell you.
Come to think of it, the stock tyres are a bit loud. Meh, beats a stripped out DC2R for noise. The 17's on the Euro make it a nice firm/harsh ride also, compared to the ones on 16's ive driven.

When you mention the automated pressure inflators at servos... i noticed...

Say i inflate the tyre to 36 psi....then i remove the hose,...and to double check, i put the hose on again on the same tyre.. and it starts pumping up from 34psi...soo its lyk soo wtf???

But back to topic, i don't think 3-4psi is goner make much of a difference in tyre noise??

[huhjared]

with the whatever tyre pressure i am running on right now its bump absorbing and quieter maybe 50% quieter than my previous tyre pressure... imagine hearing humming noise on the euro... to me that is like hearing significant tyre noise on a BMW its just not right...
