Volvo - For Life Posted June 14, 2007 Report Share Posted June 14, 2007 Hello,What is the recommended tire pressure for a 240 with 195/70/14 tires ?According to some information i managed to gather, the recommend tire pressure for 185/70/14 is about 36psi in one case and another one was 32psi.What is the difference between the two pressures, and what is recommended for what cases?So, does 36psi fit this size,? If not, what is the recommended one?Thanks in favor. Link to comment Share on other sites More sharing options...
Three Fat Tigers Posted June 14, 2007 Report Share Posted June 14, 2007 Personally I'd run 30-32 PSI around town, 32-34 on the highway. As for a maximum, I would not exceed 90% of the max found on the side of the tire, so that's the max minus 10%. Link to comment Share on other sites More sharing options...
Volvo - For Life Posted June 15, 2007 Author Report Share Posted June 15, 2007 Thanks for the answer. As for a maximum, I would not exceed 90% of the max found on the side of the tire, so that's the max minus 10%.I didn't understand - what is the meaning of the "max found on the side of the tire" ?where does this number located on the tire ?

maximase86 Posted June 15, 2007 Report Share Posted June 15, 2007 I also like using 32psi. Link to comment Share on other sites More sharing options...
Volvo - For Life Posted June 15, 2007 Author Report Share Posted June 15, 2007 So 32 It is ?What is the difference between 32 and 34 ? is 34 recommended for higher speed ? what changes with the change of the pressure ?I have seen a recommendation for 36 psi , it's not recommended ?Thanks.

wmartinlsmith Posted June 16, 2007 Report Share Posted June 16, 2007 i personally like to run a higher pressure, sorry im a goofball. must been the heat....also in my 850 the tires are filled with a different type of gas no just regular air... ill go get a pic of the brochure tomm.

dmelviØØ7 Posted June 19, 2007 Report Share Posted June 19, 2007 i personally like to run a higher pressure, cause the fl roads create a higher temp so the hot air shrinks in size, thats why they dont reccomend adding air to a hot tire...HUH? Hot air expands.I run 36 in mine, 215.45.R17 Link to comment Share on other sites More sharing options...
Volvo - For Life Posted June 19, 2007 Author Report Share Posted June 19, 2007 Thanks everyone.I run 36 in mine, 215.45.R17215/45/17 is "a bit" bigger This is a quote from the manual: psi kPa psi kPa psi kPa psi kPa psi kPa Sedan, USA 970 lbs 36 250 36 250 185/70T14 26 180 27 190 165-14 36 250 Sedan, Canada 425 kg 35 245 35 245 P185/75R14 26 180 28 200 165-14 36 250 Wagon, USA 1220 lbs 36 250 36 250 185SR14 27 190 30 190 175-14 40 280 Wagon, Canada 495 kg 35 245 35 245 P185/75R14 26 180 30 210 175-14 40 280 I didn't get it - when should I fill 32 and when 34 ( or 36? ).I am a bit confused - If anyone can explain a little - it will be great.Thanks again.

beckzach05 Posted June 24, 2007 Report Share Posted June 24, 2007 Normally, tire pressure is designated by the tire manufacturer. It is printed on the side of the tire as max load. Gives a weight limit and a psi limit. Until you figure out how the tires react under different driving situations with different tire pressures, run with the number on the tire - 10% (like TFT said). Mine are rated at 44psi. I'll run between 36 and 42, depending on what I'm doing. Right now they're at 36. Link to comment Share on other sites More sharing options...
Guest 850T-5 Posted June 26, 2007 Report Share Posted June 26, 2007 It's simple and pretty much describes the recommendation on the vehicle placard. Generally 30PSI is what Volvo recommends (minimum) for ride comfort, which is a little on the low side. Generally 32PSI is what Volvo recommends for speeds above 65MPH and for better handling with decent ride comfort. Generally 36PSI is what Volvo recommends for maximum fuel economy and for those who want a stiffer, more responsive ride.32-34PSI with most tires as mentioned in most cases is safest and should be within Volvo recommendations for your vehicle. Always use a digital gauge since those pop up gauges are horribly inaccurate and always check/adjust presure when cold. Also disregard what the tire says on the side since that is just the maximum allowable pressure.Anything above 36PSI for every day driving and even most performance driving is pretty much overkill in much cases. Contrary to common belief there really is no benefit running more than 36PSI in most vehicles under most conditions, except for a harsh ride, reduced traction and quicker tire wear. I have found 34PSI to be the best in 4 different Volvos I've owned, one of them also had a bunch of suspension upgrades and I drive them hard. Handling, traction, treadwear, response, braking and ride quality all seems optimal at 34PSI. Link to comment Share on other sites More sharing options...
PyROTech Posted July 12, 2007 Report Share Posted July 12, 2007 32 is a safe bet for almost all normal tires. Some cars recommend a 2 psi difference between the front and back, usually i see this recommendation on rwd drive cars (rear being higher). Also i make a determination on the temp outside and how it flucuates, such as if at night it drops to -25 and during the day its at like -5 to -10 then i go with the tire recommendation for the night time so if im driving at night im not sitting under inflated (btw it makes a hugh difference in psi if you pump em hot during the day and check the psi at night).
