Just curious what you guys run in 60's series tires.


I have 15" ar-23's with BFG 255/60/15 and 245/60/15

I run 28lbs in both front and rear. Firestone Firehawks.

30 lbs. all-around. They just 'feel' better; I don't like a spongy ride.

Ideal inflation pressure is dependent on rim width, so assuming that your wheels are 8" like stockers, I pump mine a couple of pounds above the numbers posted on the door jamb. Those pressures are for a smoooooth and definitely not performance-oriented ride.

Pressures listed on car's sticker relates to bias-ply tires that came on it from the factory and is not relevant to radial tires. Low tire pressure in radial tires placed on a C3 (25 psi or less) will get you blow-outs when at highway speeds for significant time (more than 2 hours). Too much side-wall flexing....

Guess I should have had a few blow outs by now. I run the front at 22psi, rear 28 psi. I have felt the tires after long runs and no excessive heat. This is not a cornering machine, at least mine isn't, so flex is not a big issue. If it was I would go low profile.

My wife's Miata likes 24 psi best. Still haven't blown a tire on that either. Auto cross and spirited driving. Pump them higher and you get a rough ride and the tires will not grip properly.

On a performance vehicle I pressurize the tire according to the conditions or the ride I want.
Motocross bike manuals state 15 psi in the tires. Run that and you'll be running off the track and sliding all over the place. It's more like 7 to 12.5 psi depending on conditions.

Consider how and where you will be driving the vehicle.

My daily drivers get higher pressures for fuel economy and long life. I'm not pushing corners or trying to get the tires to hook up.
However in the snow I can get some better traction by lowering the tire pressure on the all seasons.

Low tire pressure is relative only to the load on the tire. C3s have a fairly large tire for the vehicle weight. Nowhere near the load capacity of the tire. You can read the capacity from your sidewall but most are around 1,700 lbs at max pressure. I run my 225/70x15s at 22psi front, 24 rear.

So, while running 22psi in a fully-loaded SUV is not going to end well, running that pressure in a tire loaded well below ...like less than half... its rated capacity is not going to cause any issues.

Starting in '73, they came with radials.

I put 30 psi in mine.

O.K. I'm learning......even with the different advice.....

but it's good to know I don't have to pump them up until my teeth rattle or let them "squat" either, since I've "mellowed" and prefer a smoother 6-8 hour round-trip drive on the weekend and a few hours around town during the week.

Thanks, Men.

Most modern radial tires are rated at 45psi max, some now can go even higher. I did a
driver course a few years back run by the police department and they recommended
34psi and this was a compromise between handling and comfort. They said that the
pressures quoted by car manufactures are for comfort levels not handling.
