 Here's a good example of what I'm talking about, although he places the patch on the outside: [[https://www.youtube.com/watch?v=JC_Kf7WSa1M |sixtyfiveford on YouTube]].  Good advice about running the chords perpendicular to the tear.  If I adopt his sewing technique, then an external patch would be necessary to protect the threads?
+The patch will be adhered but can come off while mounting the tire, so have the patch opposite of where you are using the lever arms to mount the tire.

 ==== Tire Removal and Mounting ====
-Make sure to mark the position of the tire with the rim.
+Make sure to mark the position of the tire with the rim.  Many tires come with markings that should line up with the wheel stem valve.
+++++ Use lubricant! |
+There are dedicated tire mounting lubricants for sale like Ruglyde, but who wants to buy yet another product?
+Update: I ended up using straight vegetable oil.  Not messy as I painted the surface with a paper towel rather than pouring oil directly.
+Any vegetable oil works as a lubricant for mounting/dismounting.  Petroleum based oils supposedly harm the rubber.  Soapy water is corrosive.  See [[https://www.youtube.com/watch?v=JEQUlH_sTo4 |The Tinkering Old-Timer on YouTube]].  However, using vegetable oil sounds messy.  Maybe add some antifreeze to the soapy water?  Although no one mentions antifreeze, perhaps because of its toxicity.
+Silicone oil/lubricant or silicone protectant also works?  The goal for the lubricant is that it lubricates temporarily so the tire doesn't slide on the rim when in use.  Silicone lubricant does dry out, so is the residue slippery between the tire and rim?  See [[https://reddit.com/r/explainlikeimfive/comments/ywwjg1/eli5_how_is_silicone_both_a_lubricant_and_a/ |Reddit]].  Also, people who mention using it in the forums haven't had the slip experience.  There are plenty who warn in capital letters, but they don't mention having used it themselves.

+The tire bead must unseat completely and sit in a groove with a lesser diameter in order to start pulling one side over the rim.  The act of pushing the tire bead away from the rim wall and into that groove is called debeading the tire.
-Use a wooden 4x4 plank to loosen the bead of the tire from the rim, as shown by [[https://www.youtube.com/watch?v=ii8PtW8lDWY&t=150 |Smitten in the Mitten on YouTube]], then remove the tire with pry bars.
+One side of the rim may have a deeper debeading groove.  Use that side for both mounting and dismounting.  Unfortunately, this groove is usually on the outer face of the rim that you don't want to scratch.

+You can use a low profile car jack to debead the tire.  I use a concrete park bench: slide the wheel under the bench but over the jack.  May help to place a tire iron between rim and tire before lowering the jack so the tire doesn't return to place.
-Use any vegetable oil as a lubricant for mounting/dismounting.  Petroleum based oils harm the rubber.  Soapy water is corrosive.  See [[https://www.youtube.com/watch?v=JEQUlH_sTo4 |The Tinkering Old-Timer on YouTube]].

-Something else you may have on hand that works well is silicone lubricant or silicone protectant, although the idea is that the lubricant only lubricates temporarily so the tire doesn't slide on the rim when in use.

+The following is for adjusting toe on solid rear axles.\\
+{{:motorsports:alignment-plates.jpg?direct|Toe Alignment Plates}}
+++++
+++++ Easy visual toe alignment check |
+For toe, I like to use the wheels themselves for reference.  I use the tire sidewall plane as a sight on the other tire, or something pressed onto the other tire.  If the steering wheel is straight, then the sight point on the other tire will be the same on either side of the car.
+For the front wheels, it doesn't have to be exactly the same on either side, because toe-in is the difference in alignment of one wheel compared to the other.  When driving in a straight line, the caster will even out the difference to track straight.  Caster and camber are responsible for the vehicle driving straight.
+Maybe my toe alignment isn't popular because the tire sidewall could have deviation?  Maybe lasers could be used... Ha!  Found a link: [[https://nasaspeed.news/tech/suspension/setting-toe-with-a-laser-level/ |Toe With a Laser Level, Scott Gress]]
+++++
+To do an alignment on a vehicle with independent suspension, the [[https://www.subaruoutback.org/threads/effect-of-weight-on-alignment.482929/ |weight]] of the car needs to be on the wheels.
+So the wheels are free to slide, turn plates are nice because you don't have to roll the car back and forth to settle the suspension.
+DIY turn plates: 2 squares of slick, texture free vinyl floor tiles, without sticky-back, with salt applied between them.  I've been told oil and grease are too messy.
+Settling of the suspension without tools is done by push-rolling the car forward.  Does push-rolling the car forward create a drag force unlike when the wheels sit on turn plates?
+If your floor is not level, you can also [[https://www.youtube.com/watch?v=K17_oQCPASo |stack vinyl flooring]] to even out the height differences under the wheels.
+Camber and toe require the steering wheel be centered.  "If you don’t have a steering wheel lock, you can move the seat all the way forward and jam a helmet between the steering wheel and the seat."  [[https://www.onallcylinders.com/2023/08/03/how-to-check-set-wheel-alignment-at-home |Wayne Scraba]]
+If you don't have the expensive LongAcre caster and camber tool That Shop Teacher Guy has, the {{:motorsports:steering-geometry-and-caster-measurement.pdf|formula for caster}} can be had from Subearu's camber tool measurements:
+++++ Expand formula |
+caster (deg) = (180 / 3.1415) * [(camber1 - camber2) / (turnangle1 - turnangle2)]
+For a 40 deg change in turn angle,
+caster = (180 / 3.14) * (camber1-camber2) / 40 = 1.43 * (camber1-camber2)
+++++
+I don't have easy access to my wheel spindles.  I want to have a set of inexpensive wheel clamps to make things easier.  One magnet on the disc brake may be a little off, but two is good enough to make a reliable base for the laser toe-in tool and bubble camber tool.

+++++
+If you don't have a pit from which to make your adjustments like at the alignment shop, you are shit out of luck and have to raise the car to adjust camber as Subearu did.  Unless your vehicle has [[https://www.youtube.com/watch?v=CaCyi8N9XIQ |naturally curly hair]], er, I mean has "good ground clearance".

+===== Storing The Car =====
+\\
+  * Cover to protect from elements
+  * Don't use the parking brake for long term
+  * Start the car every 2 to 3 weeks
+  * Drive the car to lubricate the gear boxes
+  * Run the air conditioner
+[[https://www.youtube.com/watch?v=-Bdq5PI8s6s |How Often Car Need to Be Driven?]] by Auto Zone on YouTube.
+\\
+==== Car cover ====
+\\
+Should not be waterproof so that humidity isn't stored inside the car?  Reflectivity helps keep the car cool in the sun.
+\\
+==== Charging the Battery ====
+\\
+Modern cars have electronics that continuously drain the battery, requiring that the car be charged as often as once per week if left without use.
 A lead-acid battery, measured without load, should not go [[https://www.quora.com/What-is-the-low-voltage-of-a-12V-lead-acid-battery-before-it-takes-damage/answer/Stephen-Dudley-13 |under 11.9v]].  It only takes a dozen or so cycles under this voltage to ruin a battery.
