Tegan Langley called it a “beautiful miracle.”

As she wrote on Facebook, it wasn't that Langley didn't know her tires were in bad shape. She just didn't have the money to do anything about it. But while the young woman from Queensland was sitting in a McDonald's parking lot, she noticed a stranger at her window:

He asked if I knew about the state of my tires. I explained that I knew I needed new ones but at the moment simply couldn’t afford it.

The total stranger (who Langley later learned was a dad named Tony) couldn't leave after seeing her tires. Instead, he asked Langley to accompany him to the Bridgestone across the street:

Tony explained he couldn’t live with himself if he walked away from the situation knowing they were about to blow at anytime.

And Tony was right to be worried. According to the National Highway Traffic Safety Administration (NHTSA), there are approximately 11,000 tire-related car accidents every year, resulting in about 733 deaths.

Consumer Reports recommends checking your tire tread depth once a month, using a quarter as a guide. If the tread comes up to the top of George Washington's head, you have enough tread for rain or snowy conditions, but should start looking for replacements. If there is room between Washington's head and the tire tread, you need new tires immediately.

The tread on Langley's tires must have been very bad, because Tony insisted on taking Langley to the service station and fixing her tires ... as well as a few other things. She wrote:

$535 dollars, a lot of tears on my behalf, a few hugs, three brand new tires, a wheel alignment later and the offer to fuel up my car he left. No last name, no contact number, Just Tony the gentle giant with his two beautiful sons teaching them a life lesson.

What's more, he refused to accept anything other than Langley's thanks, merely asking her to remember his kind act and help someone else in the future:

Tony didn’t expect anything in return but asked me that one day when I’m in the position where I’m able to help someone I pay it forward.

After Langley shared the act of kindness online, the story quickly spread. Many chimed in to praise the anonymous dad for his inspiring act of generosity and thoughtfulness.

Though Langley doesn't know how to contact Tony, she wants him to know how grateful she is. As she wrote on Facebook:

“Tony if this ever reaches you, thank you! Thank you for your utterly selfless act, your kind words, for restoring my faith in humanity. From the bottom of my heart thank you!”
