    Heat cycling tyres in oven

    Always done this for new grooved radial slicks (Z214 R7 etc), but worth it for a 200TW street semi?

        Is this similar to running in a clutch or engine, which is also unnecessary yet extensively researched and championed by Motorsport nerds with OCD?

          Not really.

          There is plenty of evidence that proper heat cycling of race tyres is effective.

          In my experience, they last longer at optimum grip levels for more track days/heat cycles and taper off more slowly.
          However these were for sub 100TW.

          Tyre in question is the RE71R (200TW) but I think it's a lot lower than that in the real world.
          Original question remains, would a tyre like the RE71R provide more track days at optimum grip levels if heat cycling is performed?

            I don't have any first hand experience of this.

            But it's interesting that Tire Rack offers a service for this, $15 a tyre, but they don't use an oven, they mount the tyres on rims, and run them against some rollers.

            At $15 a tyre I would say "why not" but NFI what such a service would cost locally.

              Why can't this just be done in the first session of the day and/or at the local industrial estate on a Sunday, like everyone else does it?

                Because according the oven website the tyres need 14 days or so to properly cure.

                Probably not an issue when you throw a new set every meeting, but when you are trying to get half a season or so out of a set of tyres it could be worthwhile.

                  About $30 from memory. Probably wrong.

                    $US15 to mount them on rims and run them on rollers is cheap.
                    Much easier to just shove them in an oven and charge $30 for a little electricity lol.
                    I think the roller option would have to be more effective?

                      There's a lot of things going on beyond just the heat. My experience is that you're driving the oils out of the tyre in a controlled manner when you scrub and heat cycle tyres on your car. i don't see how baking them would do anything but make them harder.

                        Exactly. When you heat cycle them on the car you're actually stressing the fibres in the rubber. Big difference to just heating them up in an oven.

                          I looked into this recently. The science makes sense and id try it if there was a cost effective option locally. Think of it as stress relieving the rubber. There is logic to it

                            So, in theory it should be possible to do this on a dyno also?

                              Yep would be pretty much the same as the way tirerack do it.

                              Only difference with doing it on the track and doing it on a dyno / rollers is cornering stresses.
