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. Bob Wilson
