It’s the weekend, and you are finally precisely where you want to be—loading up your bicycle and heading to meet up for a group ride with the boys. Whether riding on a road, mountain biking, or something in between, you are cycling, and that is all that matters.

Then, it happens a major mechanical issue. You have a flat tire. Your friends now stand around as you fumble with tubes, pumps, and patch kits. You try to get your tire rolling again, all the while knowing you’ll never be able to get your bicycle tires back to proper inflation without a floor pump.

Or, perhaps worst of all, flat tire repair is nowhere to be found. Your group carries on as you push your bicycle back to your vehicle. 

Wouldn’t it be nice if you could head out cycling without worrying about getting a flat tire? What if flat tires were a thing of the past? It would at least be one less thing to fuss about regarding your bicycle. 

Well, this reality might be closer than you think. And if you feel like indestructible bike tires could only be the work of someplace like NASA, you’d be right.

Instructables bicycle tires 

Now, we have yet to see NASA sending a bicycle into space, but we certainly look forward to tire tracks on the moon. What NASA has been doing for a rather long time is putting vehicles—manned and robotic—on places like the Moon and Mars.

As you can imagine, Mars is the last place you want flat tires. So, NASA set out to eliminate that potential. 

Fast forward to 2020, and The Smart Tire Company (STC) was founded in hopes of finding commercial uses for NASA’s tire technology. Among these uses is the company’s new METL bicycle tire.

STC gets its name from the process used to make its METL tires or Shape Memory Alloy Radial Technology. This “SMART” tire is made of a superplastic material known as NiTinol+. NiTinol+ doesn’t stretch to absorb impacts rather it temporarily rearranges its molecular structure before instantly returning to its original shape.

METL bicycle tires are airless; therefore no flat tires ever. STC boasts that they are the “first-ever pneumatic bike tire alternative to achieve a lightweight, smooth ride, with superior handling and durability.” 

Although not fully released yet, the final product will have a special integrated poly-rubber tread pattern meant to last a rider the life of the bicycle. No punctures, no tears, no flats, no problems.

And while STC’s website only teases at what looks like a road bike tire, the site lists quite a few specialty tires, including gravel, mountain biking, and commuting.

As of now, the price of STC‘s METL bike tire is unknown. But they told consumers to expect a premium bicycle tire rolling on a high-end wheel. We’ll know more as far as price, weight, warranty, etc. as the release date gets closer.

For now, if you are interested in your own indestructible NASA bike tires, plug your information into STC’s 2024 waitlist. You can find all their information on their website.

This simple camping trick keeps bugs away without harsh chemicals
Looking to keep the bugs away with a natural solution? Try sage
Camping around a fire

Modern chemical bug repellents, while generally safe, can be a great way to keep away those pesky mosquitoes. However, these repellants often contain harsh chemicals, such as DEET, picaridin, and permethrin, which have been known to cause skin irritation risks, poison water sources, or even be toxic to wildlife. The NIH reports that these chemical repellents are not safe for public health and should be used with caution. Natural bug repellents like tea tree oil work great when diluted and sprayed onto skin, but what can you do to keep the bugs away from your campsite? Here's my sage advice for saying "shoo fly, don't bother me."
Use sage to keep the bugs away

Sage is a common herb that acts as a natural bug repellent due to several compounds such as camphor, 8-cineole, and thujone, which produce a strong aroma that repels insects by overwhelming their sensory systems. It has an herbaceous aroma that's both strong and earthy, and can often be slightly peppery or woody in scent. Personally, I find it to be more pleasant than tea tree oil, so it can be a great alternative.

What type of golf ball should you use? The simple breakdown every new golfer needs
Here are the three major kinds of golf balls and which one is right for you
A golf ball sitting in grass.

When you're just getting started with golf, you may not realize that there are several different kinds of golf balls, each tailored for a specific skill level, swing speed, or other priorities. The choices can be overwhelming, but they boil down to three kinds: two piece, three piece, and four piece. So now you might be wondering, what golf ball should I use? In this guide, we're going to discuss the three major kinds of golf balls and how to choose the best one for you.

When choosing a golf ball, you'll first need to assess your skill level, swing speed, priorities for distance control, materials, and budget. These five factors aren't the only things to consider, but they will get you to a great starting point. The key is to understand the construction and performance characteristics of each golf ball. In a nutshell, two-piece, also known as low-compression balls, prioritize distance and are great for beginners. Three-piece golf balls have better control for more intermediate players, while still giving you great distance. And lastly, the four-piece golf balls, or high-compression balls, are perfect for advanced players for their precision. Here's the breakdown:
