My Rondo EX 2008 4 cyl. have Kia original tires Kumho Solus 16 inches P205 60R16. On the tires, the maximum pressure is 44 psi. When I check it today (cold tires) the pressure was 42 psi. How pressure do you put in yours?

The tire label located on the driver's side centre pillar gives the tire pressures recommended for your vehicle. On our Rondo EX, the label indicates the recommended cold tire pressure for both the front and rear tires to be 32 psi.
The pressure indicated on the tire's sidewall is the maximum pressure to which the tire can be inflated.
I have got 17s on mine and it states 32psi all round.
at the mo I have 34psi in them, the qustion is can this small amount of difference affect the ride quality and mpg.
Reason being is I have just put £60 deisel in at £129.9 which is 46ltrs and 10 gallon, this is filled to the top and I have only got 335miles from this, which is only 34mpg My driving stlye is mixed so not all town driving some A roads and abit of Motorway as well.
Also the ride seems alot more rough and I seem to be getting alot of road feel through the steering wheel, if this makes sense.
42psi is way too high, max should be 32 on your vehicle for 'normal' usage, slightly higher if you intend to fully load the vehicle & or tow a heavy trailer. Over inflated tyres are as much of a safety risk as under inflated ones!
Heres some 'professional' advice:
Quote:
Tyre pressure:
Correct tyre pressure can help to extend the life of your tyre, improve vehicle safety and maintain fuel efficiency. Pressure is measured by calculating the amount of air that has been pumped into the inner lining of your tyre in pounds force(PSI) or BAR pressure. The manufacturer of your vehicle specifies the suitable pressure, and it is your responsibility to make sure that the pressure is checked and corrected on a regular basis, at least every couple of weeks. It's not always apparent that air is being lost, but it generally escapes at the rate of up to two pounds of air every month. More air is usually lost during warm weather, so more regular checks are needed when temperatures rise.
Maintaining Correct Tyre Pressures:
There are three main reasons why maintaining the right tyre pressure is important.
The first is safety. Tyres that are under inflated can overheat; and over inflated tyres can lead to poor vehicle handling on the road.
The second reason is economy. Over or under inflated tyres suffer more damage than those with the correct pressure and need to be replaced more regularly. Vehicles with under-inflated tyres have increased rolling resistance that require more fuel to maintain the same speed.
The third reason is the environment. Correct tyre pressures help to maintain optimum fuel efficiency. This can equate to lower Co2 emissions coming from your vehicle than those with incorrect tyre pressures and that has to be good for the environment.
TIP: Always check the tyre pressure with a tyre pressure gauge when your tyres are cold. Finally, if you are using your vehicle to carry additional load or weight, always consult your vehicle handbook for the correct loaded tyre pressure.
As to the extra hard ride, the more air the less 'bounce' & of course the lower the profile tyre the same result. I'm not sure how well the Carens works with 17" rims however I've never been 1 to stray too far from the 'factory spec' as that's what they spend millions on design costs for!

I run my 17s at 34 PSI because at 32 I had an annoying shimmy; 36 gave me too stiff a ride, but 34 is a good compromise. I've been averaging 26 MPG over 11,500 miles.

We aren't straying from the "factory spec". The Rondo's in the U.S.A. with EX trim all come with 17 inch rims. KIA recommends 32psi and I run just a couple pounds over that for better fuel economy. Manufacturers always recommend a pressure for a nice soft ride but I'd rather give up a little bit of that for economy.

True, they would not sell the 17s as an afterfit it they had not been tested.
I have got 34psi in mine the ride seems more bumpy, but I also have lost some mpg
Thank you every body. I think I run my Rondo since the Kia dealer give me the keys at 42 psi. The only reason I found for that is because the Kia dealer don't check the tires pressure when I take it for the first time. I never think to check them before because I drove in city the most part of time. This week I check it because I am going to Ocean City MD and I want to have the correct pressure to do the best mpg. I was very surprise to have 42 psi in each tire. Now I have just 34 psi that I will try for my trip in Maryland.
Tire pressure has a direct effect on the contact patch area and ride. As pressure is increased, the contact patch area gets smaller and the sidewall stiffens. Positive results from this can include better mileage (smaller contact patch ie. less rolling resistance) and more responsive handling (stiffer sidewall). The downside is a harsher ride (stiffer sidewall), less traction (smaller contact patch), and excessive center treadwear when excessively over inflated. The opposite occurs as tire pressures decreases with one important difference. A severly underinflated tire also generates excessive heat, which can result in total failure.
The harsh ride typically is not much of a safety issue except for excessive rebound on extremely deep or sharp road topography. However, the small contact patch can cause a premature loss of traction in slippery or extreme side load conditions (obstacle avoidance/sharp turns). The key is to find a good balance between these factors using up to the maximium psi allowed (44 in my case) that suits your individual tastes while still being safe.
Kia seems to think 32f/32r is where it's at. I personally find that to be a bit low for my tastes. I have the 17s and run mine at 36f/32r. The ride is a bit harsher but the handing is much better, IMO. I also have not had any trouble regarding a loss of traction either.

Apologies to Crewzin.
The UK models were 15" & are now 16" but 17" isn't standard 'over here' & that's what I meant in my post, yet another variation in the countrywide spec list!
