Six of one! While not a common a practice with the latest radial tires, it's still being practiced.
We aren't talking 10lbs+ here, only~4 or 5 lbs.
My 2¢
get the name of the tire contact the tire manufacture show them what you just posted as well other information you responded with on this thread and see what they say. PLEASE POST THIER ANSWER!
You realize i the racing Performance world accuracy to /12 lb makes a difference why should it be any less on a daily driver. After all Performance testing is where many Tires get there designs for all of to use.
The buck stop at what the *manufacture of the vehicle say and the tire *manufacture. POST THIER INFORATION
Follow *their information and you will be safe and get the best performance out of your tires!
It is actually easy to see that what the auto manufacture recommends for a tire pressure is accurate on the tarmac. If you are using the correct best tire size for the wheel chalk can show you in only 25-75 miles what is going on with your alignment and the pressure chosen to adjust your tires to!
Adjust your tires as per the the recommend pressure in the owners handbook or the doorjamb of the vehicle. Then draw a solid chalk line across the width of the tire . Drive normally and occasionally have a look at how the chalk is clearing off.
Here are my really old pictures that I have used on forums for almost 2 decades. Unfortunately they are now water marked by photobucket . I am not going to dig out those old CD'c with the original picture I took to post unmarked pictures for this exercise on this thread. Sorry!
Front tire
Rear Tire
In another picture you can also check the tires operating temperatures and compare them to several values including road temperature and ambient to see how different tire pressure effect the temperature's. To high as well to low from recommended will increase the tires temperature during driving! This is yet another reason why we follow the recommend tire pressure.
The last item would be the safety measurement stopping. This you would need an accelerometer gauge. You can accurately measure the 60mpg to zero/stopped time and distance as well the lateral holding of the vehicle on a flat surface during hard steering. You can even measure the grip G-force of a tire and the chosen tire pressure . Tire pressure dramatically effects all 3 of these performance and safety aspects. So ya once again staying with the recommended tire pressure will give you the safest and best performance over choosing your own tire pressure to use!
If I checked with Mazda about tire pressure, I pretty sure they'll tell me that same as if I asked
about adding 'high performance' parts. A major case of CYA.
I've been running my tires hard for over 30 years. That's plus 4to5 lbs. over.
That's three season pressures, when the temperature drops down to 32° and lower,
the pressure drops on it's own to about where the door sticker says.

LOL ...oops..... another inaccurate statement from MR 2cent Dennis.....hahha !
There is a complete support and sponsorship program offered from MAZDA that even include factory engineers and technicians who assist in those that get accepted into the program. Mazda Motorsports
Dennis just for you to help you support or disclaim your information here is a few numbers you can contact regarding tire pressures!
I would include my contact number as well but we all know what you consider my information is worth! lol
we all know what you consider my information is worth!
Well we all know what YOU consider your information is worth.
For the most part, your info is usually good. A little less condescending would make
it even better.
As I've said, I've run my tires on the hard side for over 30 years. While tire life is
improved somewhat, the fuel mileage increase is likely to small to calculate.
Check with some folks that run rallies, track days, and/or gymkhanas.
I'm fairly certain that they increase their tire pressure by at least 5 lbs.
The CYA involved is unbelievable.
Sure Mazda has a motorsports division. And I'm sure that all your gadgets are company approved,.
right?
You do what you do and I'll do what has worked for years for me and those I know.
I have tried to edit out the size in the text but my word program is not being user [size=13px]friendly[/size]. So I am sure most can read the [size=13px]sentence[/size] even with the font [size=13px]structure[/size] information....

2) A little less condescending would make
it even better. Many who know personally me and are also on forums will contest I am this way in the real world as here on this forums and other forums. I dont BS around and I don't really put up with inaccurate information on a thread I am participating on! I do not purposely try to be [size=13px]condescending[/size] , insulting or any other [size=13px]description[/size] of that type.
3)As I've said, I've run my tires on the hard side for over 30 years. This only means that you may be doing thing incorrectly for that time period?
4) While tire life is improved somewhat, EMPIRICAL speaking and DATA can back this point up that increasing tire pressure on factory wheel byond the recomend manufactures values will wear areas of the tire unevenly and prematurely then designed.
5) the fuel mileage increase is likely to small to calculate. Actually Dennis this is one point you got it right. [size=13px]Mathematics'[/size] comes in to play along with aero dynamic's and friction resistance. By increasing tore pressure you lessen the [size=13px]contact[/size] area on the [size=13px]road[/size] by narrowing the tread. This mean less and I simplify only to save me from having to type for the next 20 [size=13px]minutes[/size] the [size=13px]technical[/size][size=13px]dissertation[/size] , the rolling resistance thus increases MPG.
6) Check with some folks that run rallies, track days, and/or gymkhanas.
I'm fairly certain that they increase their tire pressure by at least 5 lbs. How can I even start, Dennis most guys are running track only combination tire and wheels, they dont care about wear and MPG and NO THEY DON"T just jack the tire pressure without considering thing like traction suspension setting the road course itself weather conditions and temperatures of the air tarmac and ambients...to name only a very few... As I have said and posted I race professionally in NHRA,SCCA and a couple other sanction events. We are always adjust tire pressures for best possible times on the track . On my [size=13px]daily[/size] driver specifically my MAZDA 3 factory tire and wheel I use recommended tire pressure from MAZDA.
7) The CYA involved is unbelievable. = What does CYA mean in a text? Slang: Sometimes Vulgar.cover your ***. See cover (def. Not really sure why you always use this CYA it make no sence unless you are assuming that tire [size=13px]manufactures[/size] and the automaker do this to you [size=13px]personally[/size]? I guess who knows with you? lol
8)Sure Mazda has a motorsports division. Yes they do and if you contacted them the people that answer the phone are polite and extremely helpful and supportive. Try it sometimes you may get more appreciation for MAZDA
9) And I'm sure that all your gadgets are company approved,.
right? Um there is no such thing as approval or not anywhere that I am aware of. And if you are refereeing to the WARRANTY on my MAZDA I am fully aware of what I have and will no longer have covered should I need to utilize MAZDA warranty program on my 2018 Mazda 3 in the future. Maybe you should go look more carefully at my thread and reconsider you comment based on what I have actually left or installed on my MAZDA. Maybe now just maybe I considered the mileage before leaving anything that my effect the warranty. You may be surprised to notice I have started numerous projects but how many have you seen finished and left on the MAZDA?
10)You do what you do and I'll do what has worked for years for me and those I know Dennis, Dennis, Dennis.... lol This is always an argument, the thing is when IO am on a forum and someone does something that is not safe then I am compelled to write about it. You see your unsafe service and DIY could cause not only your car to be damaged but you could cause an accident that could effect others in the capacity harming them or there personal property like their vehicle.

"3)As I've said, I've run my tires on the hard side for over 30 years. This only means that you may be doing thing incorrectly for that time period?"
The other possibility is that there is something you can learn from other's experience.
I've run my tires hard (+5) for well over 30 years. the is not 'dangerous'. And the wear
pattern looks normal at the end of their lives.
Mazda, like all vehicle manufacturers, set their tire pressure recommendations with a compromise
in mind between smooth ride and optimal handling. You know this.
I choose to move the scale slightly more toward the handling side.
I'm no racer by any means, but I've know a few and even that link I posted stated that
those that push their cars in rallies or track days, increase their pressure.
I think you know what CYA means and product manufactures go to great lengths to keep
their behinds out of court.
Your quote (mostly) "Off road parts or performance after market parts disclaimers keep most manufactures out of court!" .. End Quote (mostly). Well you can guess why and I can say you are WRONG again.! It is not exactly what they are there for. They are there because most DIY should not be installing them and most DIY are the ones that blame the product and not their lack of experience with tools and installing parts and maybe even a little practical common sense. LOL
I dont use disclaimers except when it comes to some regulation in some states about what they classify a modified part is. And also I engineer and develop parts that will work for the most part no mater who and what level experience installing parts are. . In in 40 years I have never been in court because of something I made and sold! NEVER !
As for you blanket response about most all increasing the air pressure on a road track , auh ok LOL! you dont race so I accept that you really dont understand or know why this is not true!
You win I can't debate anymore with the level of experience on the subject of tire pressure that you have .
You can respond and have the delightful champion last word... I have no more to contribute in this thread .
On my last car - 2017 Audi A4 Allroad and some previous cars that I had, I always followed the recommended tire pressures that were in the manual. There they listed the particular pressures for the particular type tire as well as what the load would be - normal of full. At least on the Audi, the pressures listed on the door are max tire pressures. I ain't no tire expert, but tires are literally and figurately where the rubber meets the road and I adhere to the recommended pressures. Just because some people have not NOTICED a problem - hydroplaning, longer braking distance, shorter tire life expectancy, does not mean these issues are not present. I mean how can you measure that braking distance or any of those issues would be present? So that's why I rely on the recommended tires pressures as well as conversations with people at Tire Rack. Using the recommended pressures and checking them frequently, costs me nothing more and gives me a sense of security.
