    A slow tire leak was caused by an inside, cracked rim (see photo). So I had a 2,000 mile, used, 235/45R18, Tesla Model 3 tire, removed from a spare rim. This used tire is available to anyone who wants it. It's brother will be available in late January if you want the pair:

    After making a cut, the disabled rim will be sold for scrap aluminum. As for the Tesla tire, free to whoever wants it.

    I do not like the Tesla stock tires:
    • too heavy - my Model 3 weights 3,800 lbs and this tire is also used for much heaver models.
    • short life - typically rated at 36,000 miles, my first set barely made 30,000 miles.
    • high tire resistance - squishy, they cause more rolling drag than the ones I use.
    • dynamic instability - in some conditions, these tires develop a resonance with Full Self Driving that is unpleasant and can go divergent.
    I will never drive another mile on Tesla recommended tires. Too costly and in some cases, unstable.

    I’ve dealt with model 3 rims/tires: first time I laid one flat on a concrete slab it was alarming to hear a clang, the rim is wider than the tire. Tesla engineers must be aware of this. Or maybe not?

    Lug nut torque value is an eyebrow-raising 129 ft/lb.

    More a case of coming up with a rim that doesn't surpass the spec'd tire in width.

    There are tires that project outwards just to protect against rubbing the $$$$ rims. My Mich CC2s have such a feature of their design.

    Yeah, our 3'rd gen's 17" Michelins are thus, has a ring of rubber projecting further out, about 3/16" I think. Still, with/without this, the Tesla 3 is the first time I've encountered any wheel/tire combo thus.

    Cracks seem to be a 'thing' with T3s according to the interwebs - although I do not know if this is a design issue or just people who do not know how to avoid potholes.

    The torque spec isn't super crazy but it seems a little high for a fragile aluminum rim.
    IIRC the specs for my truck's 'steelies' is either 110 or 120.

    The wear rating IS interesting.
    Tyres that are 'energy efficient' are usually hard as a billiard ball - meaning you can run over a dime and be able to call "heads or tails."
    Engineering is compromise.
    You trade handling and comfort for 'efficiency.'

    Curious......
