Hi
I weighted my original Wheel/Tire (my fifth wheel inside the trunk)
205/55 R16 with 35 psi. The Total Weight is = 43 lbs
In past posted I read that only the Wheel weight around 21 lbs.
What about the other 22 lbs? How much weight influence the psi over the Wheel/Tire?

Sorry. How you call the wheel inside the trunk? Sparewheel?

Not enough to be concerned about. Probably a good bit less than 1 lbs.

Only 43 lbs? Thats good, I weighted mine and the 205/60-16 came in at 47 lbs. Which, if correct put the tire at 26 lbs.

I gotta find lighter rims and tires. :D

Especially for a Mazda wheel, they are normally some of the lighter OEMs.

The 16x6.5 on the '01+ Miata's only weigh about 16-17 lbs. That's for a much lighter car, but 21 lbs is HEAVY to me.

Some of the RX-7's 16x8s are only 15-16 lbs range. I was really surprised to see the 16" and 17" 6 wheels listed at 21 lbs.

Yep. But the Total Wheel Weight is 43 lbs
If the wheel weight suppously 21 lbs according some posted, the other
22 lbs are in the Tire/Air Pressure. Is not a lot?

22lbs for a 205/55-16 is a very good weight. I would guess that your car comes with Summer tires as compared to the M&S (all seasons) we get in the US.

22 lbs for a 205/55-16 is.

My 205/50-15 Falken Azenis on my Miata are 23Lbs. The 15x6 rim is only 13 lbs.

It's not the tires that are heavy, the 6 rim is very overweight.

Air pressure is actually almost insignifcant. The majority of the weight of a wheel/tire is the wheel and the steel & rubber of the tire. A quick calculation using the ideal gas law for air and an approximate volume for a 205/55R16 tire (sea level pressure and 25C temp) gives a mass of air of .12kg (.26 lb) at 25psi. If you raise the pressure to 32 psi, you increase the mass proportionately to .15kg (.34 lb). So, compared to the wheel and tire mass, there is almost no mass due to the air inside. You can easily verify this by weighing your tire, deflating it, and weighing it again. Unless you have a very accurate scale, you will not see any difference.
