amandal Posted September 15, 2011 Report Share Posted September 15, 2011 Guys, I have recently bought a RR Sport Supercharged 06 model fitted with Continental 275/40 R20 tyres. Do you have any idea what should be the ideal tyre pressure on these tyres given the fact that I drive just by myself 90% of times. Link to comment Share on other sites More sharing options...
bmwdoc Posted September 15, 2011 Report Share Posted September 15, 2011 i would run them at 35psi front and rear and 32 in the top summer months as the heat will inflate them more. these are cold pressures. so check first thing in the morning before driving Link to comment Share on other sites More sharing options...
amandal Posted September 15, 2011 Author Report Share Posted September 15, 2011 Thanks Doc. I am currently running them on 38 psi for all 4. Sounds like thats too high. Link to comment Share on other sites More sharing options...
Gaurav Posted September 15, 2011 Report Share Posted September 15, 2011 These tyres upper limit is upto 40 when under full load. However keeping in between 30 - 35 all tires is quite appropriate. When in city as Dubai traffic keep at 30-32, its the best pressure for comfort and safety. As higher the pressure lesser the comfort you get in city over the bumps, and while on highway keep at 35 is best and you will get better fuel mileage. Let's root for each other & watch each other grow. Link to comment Share on other sites More sharing options...
nutbolt Posted September 15, 2011 Report Share Posted September 15, 2011 Every tire hold imprint for max load and max psi. Check that FYI. However 30 - 35 is quite safe range to inflate tires in Dubai hot and very hot weather. lol. @Gaurav: I doubt its 40, it should be more atleast 45 psi.
