TIRE PRESSURE
Use the car internal tire pressure system as a guide only.

There is only one sure way to measure tire pressure and that is with a proper tire gauge which you can test for errors at a gas station using their system.
All tire should read as stated on the drivers door frame.
Tire pressure is dependent on where you live road quality and the type of driving you do it is up to you to determine the sweet spot.
I add an extra 2 P.SI. to the front wheels in all my cars.
You should verify the tire pressure and physically look and foreign objects in and including side walls in all tires for at the beginning and the end of the journey.
Rim leaks may be re sealed and re seated by deflating all tires by 10 pounds an driving the car forward and back a few feet then re inflate.
The best way to check for leaks is with soapy water in a home trigger sprayer you also might check if all Schrader Valves are functioning they could be loose or defective , there is a three way tool available for that.
Heat build up may be caused by hard driving ,under inflation, excessive hard breaking, and or very hot roads.
Tires performance change as tire wear down to say 2 /32.

apparently you have to drive it to get accurate tire pressures as they went down to 34 psi when driving but kinda defeats the purpose of checking
the tires "when cold" as Mazda manual states

TIRE PRESSURE
I guess you know when discussing tire pressure the experts are going to ~~~~~~~~~~~.
so here are my opinions which i will try to do in about 100 words of text.

As you are most likely are aware , the engineers at Mazda, after, say extensive of testing their car have come up with ,as i take it, a guide line for their standard tires which they install on their new cars, other manufactures quote different pressures for the same tire.

Most likely ever manufacture will set pressure levels at over 30 being the absolute bare minimum.

What is important here is is all about safety . Speed kills !

At 20 mph to the Supermarket or 100 mph out in the desert where temperature affect tire pressure differently in each tire on the same vehicle as do many other road and load conditions like engine weight and the type of driving .
I am not going to tell the Forum what tire press is best for their cars but i can tell the what tire pressure is best for my CX3 with my 215 Toyo tires 36F & 32 R
that is this week , now I have a problem the roads here are very hot that drives the pressure up by 3 to 4 lbs , I will change to 34 F 30 R.
You will know when you have found the sweet spot, as the car seem to float on air and steering will improve .
What bust the bubble is speed, the faster the car the greater the front end lift reducing ground tire patch.
Two passengers at say 300 lbs in total changes the tire patch and every thing else.
The next problem, is ,excessive tire wear as with under inflation the corner sidewall loose tread, we are playing with 2/32 this where thing can get dangerouse at the end of time, from on average of 10 /32 as new.
Over inflation , the center of the tire tread wears ,it is important to see the point where the tread meets the side wall when driving, it is also important that the tire tread wears evenly. Think tire patch.
What are tire tread for? it is for disapation of water on wet roads ( Here, we have Duck Ponds) to prevent hydro planing resulting in rear ending others.
I don't know, and Mazda don't know ,what condition you are driving under , only you do .
Fix it !

A16 year old girl died on here on our roads two days ago there is 30 ft of flowers an balloons on the side walk ,that will not bring her back.

Be careful, drive safe ,the life you save may be your own.

All this is off topic every body !

I don't care for hurricanes much now we are getting tornadoes my car has been through three so far
I teflon coated it with a teflon boat polish got two application so far from last year.
I have to get it painted machine grey next time i hope i don't have a problem there .
I hope i have got you on the right track with tire pressure
The Mazda CX3 is a firm ride it has got some sports car heritage.

BUMPY RIDE
This is an amended post. of #48 as deleted.

Bumpy ride is a very general description of a car performance.

No doubt that many of you have recently seen a new car in cabin demonstration on youtube video, where ,if you take you eyes of the road you will notice the drivers window/ dash board appear to rise up and down according to road conditions.

Alternatively with older vehicles, this situation, becomes more pronounced ,if one or both or the both front shocks or the suspension joints have been damaged or have seen better days .

A loose front wheel should not be ruled out .

The quick fix, owners manuals will always recommend that car be taken to a qualified mechanic.

Fact checking a car requires the expertize of a professional.

Car bounce is a serious matter.

In comparison many years ago some western style , very large heavy cars, came with very soft suspension with fat balloon tires, here is where the wheels used to bounce in the wheel wells, if the wheel did not bounce we would not buy the car.
How things have changed !
Since then, there have been many advances in car usage and design ,the ride in modern cars ,is firm, being the exact opposite of 50 years ago, engineers and manufacturers to day know what they are doing , their reputation rides on it .

Today many want high performance tires , what does that tell you.

Some owners will modify their cars changing out wheels and tires there by increasing un sprung weight, causing an energy transfer.

In order to save a on gas cars are much smaller and lighter in weight all in the quest for performance ,the car chassis are a thing of the past. now the car body does the bouncing.

The energy has to go some where.

I own a CX-30 Turbo Premium. There is a lot I like about the car, Looks good and fast. BUT, the suspension is completely insufficient. I can hardly believe how awful this car is on bumpy roads. The car shakes and you feel everything through the rediculously skinny steering wheel. I am not sure what's worst, the front end or the rear end. Tires and tire pressure is NOT a fix for this situation.The design team should be FIRED! Hope it doesn't shake apart before I want to sell it in three years or so.

I bet the new rear-wheel drive models will have them. I would put money on even the CX-50 having it, even if it is based off the CX-30.

according to reports the CX-50 is based on the CX-30 so not sure what the differentiating features will be. If they opt for rear multi link this would go a long way to improve ride quality, but not so sure as I find the rear does not exhibit the “hop” like the CX-3 does. There is a fair bit of cowl shake even with wider / softer tires.

I think they did a superb ride-handling compromise with the 1st gen Mazda6 but dang that car had the turning radius of a school bus and my only real complaint about the car.

I am planning on getting a strut tower brace to see if it improves and maybe coil overs.

i still firmly believe the CX-30 stock tires are a big factor, that and adjusting tire pressures down a bit was quite dramatic (read my earlier posts in this thread).

IRS only appeals to enthusiasts. The average car buyer has no idea. Mazda is clearly targeting the average car buyer. Mazda put the money in the interior where it counts. Mazda needs to sell vehicles, not please a diminishing number on enthusiasts. I'm an enthusiast so I'm not attacking anyone.
If the buyer doesn't do a reasonable test drive, well, that's not on Mazda.
Times have changed. People's expectations have changed. I don't blame Mazda for needing to sell vehicles to stay in business.

Over on the Mazda 3 site several posters ,who have had both, say the twist beam gen 4 rides better than the IRS gen3. I have had both and to me which rides best depends on the tires and the tire pressures so I do not think the twist beam is mostly responsible for the 3's or 30's brittle ride. Better tires at lower pressures made my 3 livable but it will never be a car to do well on a bumpy road. It's stiff for better or worse to prioritize handling and has considerable unsprung weight.

Regardless enthusiasts or not the suspension on this car is awful. My mom 2007 Toyota Camry is better on the bumps. There is no excuse for that.

I've got no problem with the suspension on my CX-30, so it's only "awful" to you. Comparing it to a 2007 Camry doesn't prove anything, two completely different vehicles. Now if you compare the ride of the new Mazda 6 to a new Camry then you have a fair comparison.

Ride can change slightly over time as you get more distance on the vehicle.

Also on a side note, when I was checking out vehicle before purchasing, I test back to back to CX-30 vs the Kia Seltos and one of the things I really noticed was the much more solid and composed ride the CX-30 had over the Seltos over the exact same road surfaces and one of the many reasons that swayed me to the CX-30.

Good lord, seriously? I have never been in a Camry that rode well (haven’t been in the newer ones, mind). It seems like there is such a lack of stiffness in the chassis that to be competition between where the front and rear of the car wants to go , bushings wear fast so there is a lot of harshness, rear end bottoms out with passengers in the back seat, mushy steering… could go on….

But hey if you like the ride who am I to judge peoples preferences.

Basically if you don’t like the ride of the CX-30 go to a tire shop and ask for tires with the best ride comfort. It will transform the car.

I've got to agree with Random. If you're comparing anything to a 2007 Camry, I sure hope the comparison doesn't find similarities. At least now, I understand where you're coming from.

Just add a couple of inches to the wheelbase, 4 inches to height , and IRS to the 30 and you are making another CX 5. I am ate up with curiosity about what's going on with the CX 50. Could it be a taller and more space efficient but less sporty than the 3? That makes some sense as the Toyota they are making on the same line reflects that configuration and the length splits the diff between CX5 and CX30.
