some questions
 

I just bought a schwinn mountainbike because i wanna go riding and maybe even take my nephews out for bike rides because i wanna get healthy because at the age of 22 (there not my real nephews just really close family freinds) having a blood preasure of 160/100 or a standing heart rate of 130bpm is preety bad.....

So my questions are as followed

1. Will Airless tires from this site work or no? http://www.airfreetires.com/shopping/c-14-26-inch.aspx
2. Should i go airless or tubeless
3. and finally: How secure are these 2 options

I know it would make more sense to carry tubes and pumps but il be riding on highways and offroads 30miles+ from my house and i wont be able 2 carry those all the time nor will i have the space to.

Im just really needing something so i dont need to worry about flats or punctures

thats why im considering airless more then anything but i was told im stupid if i buy them

can someone please give me advice i want to do airless because im convinced it will not pop but what do i do can someone help asap cause if i need to order stuff i wanna order soon.

I agree with the responses you got in the mechanics forum:

Neither. I'd get some puncture resistant tires(e.g., Marathon Plus) and you should be good to go.

You can carry tubes and pump all the time. I do. I have a frame mounting pump with built in gauge w/ reversible head for schrader and presta valves, and I carry both patch kit and a spare tube. When I go riding with a group, I attach extra panniers and a big 1st Aid kit goes on one side, with some water and snack bars, and I have tools for chain, headset, pedals and standard 14mm/15mm for axle nut, spokes, and standard 2.5mm - 10mm allen and spare tubes in sizes for other riders I'm supporting.

The key to avoiding flats on rural trails is to avoid riding over brush and thorns. Riders must pick a line and ride over durable surfaces that have no growth. I help with large annual bike ride that happens every October down near San Jose. We get thousands of riders that day. The sides of the trail are lined with dried goat head thorns in October. And few tires can withstand that. My record is extracting 19 thorns out of one boy's tire, and since I didn't carry such a small spare tube for such a tiny bike, I had to patch the tire. 8 total patches. The tire held air for the last 4.5 miles and he made it back. But why did he get all those thorns? Because he didn't concentrate on holding his line and swerved around back and forth, and ran over a big patch of thorns.

It might be such a hassle that the instinct will be to get no-flat tires. But there is a reason why 100% of the folks in Mechanics forum said "no" to no-flat tires. Because they ride like crap. So if you actually want to go riding and what to enjoy it, you'll stay away from such tires. Even mr. tuffy tire liners ride like crap. If you had a chance to ride decent tires (and yes, they cost more and aren't likely available at Walmart) you'll agree, they ride a lot better than any of those tires.

For most trails, though, I've yet to have a puncture on an MTB tire in years. Road tires yes. But MTB tires have knobbies and thick tread. I haven't had to fix any MTB flats due to punctures in years.

The less weight you carry the better off you will be. I wouldn't go on a long ride without a pump attached to the bike frame and a spare tube or at least a patch kit with glue. I absolutely despise "thorn-proof" tubes. They are stiff and awfully heavy. Anything that adds weight to a wheel has way more effect on a bike's efficiency than comparable weight added to the frame (ask a physicist why!). You can carry all of this in a small bag attached to the bike.

The weight of the tube is probably irrelevant (the whole must have light wheels thing is completely over-blown unless you're racing). What may not be irrelevant is that thick tubes/thick tires will have higher rolling resistance and that can slow you down significantly at lower speeds.
