front end sound
did anyone notice a metallic sound from the front end when they go over speedbumps or just any bumps at low speed?
it sounds sort of like the brakes are scraping, hope my rotors aren't warp. |
Check your air pressure.
Funny I had a weird noise and I checked the air pressure it was 35.
The tires should be at 45 and higer. If you look at the tires it should be maxed 51... Well I put them 45-47, noise is gone... That what helped me..... but I am not Mazda mec man....:D |
wow, 45psi seems kinda high. my owners manual recommened 32psi all around. im running at about 35 also, 10 more pounds might fix it, but i heard you'll get less traction at higher psi, dont wanna take a chance of skidding around or worse a blowout.
thanks for the suggestion... |
Look at what ther Tires say...
Says 51 Max.
Unless I am reading wrong...:dunno: :laugh: :blue: |
My front suspsension squeaks like that... the service guy said it was the bushings and it happens when they get dry.
He also said he lubed them up to stop it, but it still squeaks so I guess either I have to find the right kind of lube to use or take it back to the shop. |

The max tire pressure on the sidewall is the max safe (probably structural) pressure. If you put it anywhere close to that figure, you will exceed it when the tire warms up. Not to mention, like previously stated, you wont have anywhere near the traction you could get at recommended pressures (overinflation creates a smaller contact patch). Also your ride will be much harsher at very high pressures, and youll get very poor tire wear characteristics. When Mazda decided to go with the tire on your car, they did much testing to determine the best pressure for the desired traction, ride, and wear characteristics. Sure, those who race may vary pressures a little bit to tweak their handling, but the figure Mazda comes up with is what they considered the best compromise for what they designed their car for (sporty street driving in the P5's case). A buddy of mine used to run his Nittos on his mustang at full (sidewall) max pressure, and couldnt figure out why he kept spinning his car out on freeway on ramps...:) |

So when I asked he said " Keep it aroung 45 psi" So I said the same thing why did it say 35. From what he said that is not the low profile tire specks ,and mazda is addresing this at this time... :doh: :dunno: :crook: |

Unless you're running some special low rolling resistance tire for a zillion miles per gallon, 45 psi is insanely high.
The 32 psi number is just fine for most cars. Besides don't you think if the 32 psi was some sort of misprint, Mazda (Part of Ford [remember Firestone]) would be busting its a$$ to send out letters warning owners of blowouts and underinflated tires? Tyson |
Trust me this guy has never been wrong.

Ok thanks all
I will do that...:D

Most modern radials will work fine between 30 and 40 psi, but 45 will degrade the ride too much and may cause a wear problem. I recommend 36 psi front and 32 psi rear. |
Re: Re: Re: Look at what ther Tires say...
Originally posted by carguycw Actually, he should be fine running higher pressure, although 45 psi is probably overdoing it. Higher pressure in the front tires is ESSENTIAL for decent handling in a FWD car. Unless you have race tires, 32 psi is NOT enough to keep the front tire sidewalls from rolling over and making the car plow; IMHO you need AT LEAST 35 psi on the street, 40 on the track. This will HELP traction in the front, not hurt it. The manufacturer's recommended pressures are set to (a) make the car ride softer, and (b) make the car plow to keep the lawyers happy. It will NOT make it handle better. However, 45 psi really is too much, particularly in the back. Most modern radials will work fine between 30 and 40 psi, but 45 will degrade the ride too much and may cause a wear problem. I recommend 36 psi front and 32 psi rear. |
