Does anyone know what the recommended tirepressure is for the 1986 Camaro (IROC-Z)?

I have a set of Dunlop low profile tires, and Dunlop recommends that you use the car manufacturers specs--- which is found in the owners manual or in the driver side door jamb. I no longer can find my manual, and wouldn't you know that the only number that is faded out on my door jamb sticker, is the tire pressure reading.

Any help would be greatly appreciated. I am tired of buying tires.

 

Start out with 32 PSI for your tire pressure. I would run nothing less and max out about 38 psi.

 

the recommended tire pressure is 30psi. for more aggressive driving use 35psi. that came right off the door sticker.

 

if u use less than 32 then u will have uneven tire wear. look at the tires. if there max pressure is 35 then put 32, if there max is somewhere around 44 then i'd put 35, i have a 86 z28 and i always keep it at 35.

 

I know you said Dunlop recomends the car manufacturers spec's, but just to be safe look on the side of the tire and see if it says any thing.
reason I say that is my rear tires require 55psi which is quite a bit higher than factory specs, and any thing short of that and they dont feel right.

 

i have 27-28 all around right now. but 32 psi is a good place to be.

 

27-28 is a good pressure for winter weather but for a summer like climate i highly reccommed 32-35 P.S.I

 

Thanks guys for the input. The side of the tire says max airpressure is 50, and when I run anything less it just doesn't feel right, but I will try the 35 psi and see how tire wear is then.

Thanks again.

 

Just because the tire sidewall says 50 psi Max, thats it MAX
and not the air pressure you operate the car with . Your tire pressure is always lower then the Max. Again 32/38 is a good range.

 

Also, keep in mind that as you drive, the friction between the tires and the road cause the tires to heat up, and as a result the tire pressure increases. I don't know exactly how much, but I definately wouldn't recommend filling your tires close to their max pressure rating. Having a blow out whiles driving, especially on the highway is not cool.

 

32 psi but the center of the seems to wear out faster than the sides so I took it down to 30 and that seems ok.

 

also remember higher psi means youll have quicker steering response but it will be easier to break the tires loose not to mention it will be a bit less comfortable driving wise.....lower psi means youll get a bit more body roll and it will stick a little harder but wont respond as quickly to steering input.

 

For all around driving I have found 30 to be the best. For Auto-X, I would go up to 45 and for street racing (hypothetically only) 25 rear and 35 front.

 

An interesting thing to note, is about the whole 'lowering tire pressure when racing'. I read an article a few years ago that stated that lowering psi in street radials actually is worse for traction, and the tire. Mainly because of the way they're designed. It said that when you lower the psi, you're actually causing the middle area of tread to suck inwards into the tire, which actually gives you less traction. Don't know how much truth there is to that theory. And of course this doesn't apply to street slicks.

 

I would suppose that if you didn't get too carried away by going to say 15 psi, you'd be allright. I can gain a couple of mpg by raising my pressure by 3 psi or lose a couple by dropping down 3 - 4 psi from stock 30 psi.
