  • E30 M3 EVO tire pressure

    does anyone know the recommended tire pressure on the E30 M3 EVO with 16" rims as standard?
    or ideally does someone have a pic of the tire sticker on the left door?

      there is nothing in that thread that says what the factory recommended settings are.
      i did search and did read that entire thread
      it's what some users have tested
      which is not what i asked for

        You are right. I apologize.

        Here is some info. I can't locate my M3 supplement, but here is the "Sport Evo supplement" page that you asked for.
        I converted the numbers from bar to psi. Top numbers are for 2 people, bottom is for 4, and vorn is front.

        THis is from the regular 3 series manual that comes with the E30 M3 supplement.

        I'm sure someone can post a link to it.

          thank you

          sorry if i sounded harsh earlier
          cuz i am usually careful before i post a new topic
          and i usually try 3 or 4 searches with different variations
          like transmission or gearbox etc

          i had them at 30 front and rear
          i am usually alone
          i will try 32 and 35

          why is it more for the back?
          isnt there more weight at the front so you need more pressure to hold up the weight?

            It's OK, you meant business, and you were correct!

              I would think the recommended tire pressures are to assure a bit of understeer. I kinda think you would need equal pressures front and rear..............just my take on it.

                i had them set to 30 all round
                but when i went with the recommended, it felt much better
                grippier and actually more comfortable
                i didn't push the limits so i don't know if it was tending towards oversteer or understeer.
                but i would recommend everyone with 16" 225/45 to at least try the factory settings

                  I haven't played around with pressures so much (tend to run factory values above) but I suspect the higher rear pressure is to improve stability in dynamic manoeuvres. Most cars these days state their laden rear tyre pressure at just under the maximum allowed by the tyre manufacturer to get the best result in elk tests and such like. It's difficult to run this pressure at unladen conditions though, as it tends to impact on ride comfort - not so much of an issue when you don't have most of the weight on the front axle.

                    Depends on application and what type of tire you're running.

                      Yes, I find the recommended settings are a really nice setup. I play around 32-35 in the front and 36-41 in the rear.

                      With H&R sports I have 4* negative camber in the rear so I use the higher tire pressure to give me a little bit more neutral feel. Around 33PSI front -40PSI rear mostly. Also like was mentioned above, the ride quality is best in that pressure range.
