Hello everyone,

I've got a 1980 RX-7 running 13 in. wheels and stock tire size (185/70/13). I might be blind, but I couldn't find a recommended tire pressure anywhere on the car. Does anyone know around how much air the tires need? I can't say what pressure they're at now since I can't find a gauge to save my life, but they are definitely looking a bit flat.

I appreciate any help,
Thanks y'all.

 

Being that there are Numerous tire companies popping up since the car was actually put into production,I would not go by the Mazda info if it was on the car anyways.
The tires produced now a days, usually have a maximum inflated pressure stamped on it to go by.
32 psi is about the normal pressure to run on a regular running vehicle.
Some tires can hold up to 50 psi but that depends on what they are designed for.
You will find that the car will act differently under various different tire pressures too.
Personally,I keep my tires at a higher PSI and then when it gets lower I know the Feel of a sloppy car means that I need to put air in the tires.It's not often that happens but it is good to know.
But If you pay close attention to Maintenance and keep the tires inflated,then you are good to just keep them at whatever PSI you and your car feel well at.

 

I headed out to my gas station and checked out the pressure...20 psi on all corners! I know 32 is kind of the universal tire pressure, but I figured I'd check it out just in case someone else knew better. As expected, the right pressure = a better ride. I hadn't realized how rubbery the car felt in a turn before I filled up the tires, but at least now I know how the car shouldn't feel.

Thanks again for the info.
