SO air free tires are not solid ?

johnathansassak

Never use Airless Tires, the ones with thousands of tiny microscopic air cells, You Will Die if you do, the ****ing tire rolls right off, I got a nice fresh flesh wound from these pieces of ****, I was considering suing the company that made these tires, but thats too much of a headache, so Ill just write this bad review on how suicidal it would be to use Airless Tires

johnathansassak

Airless Tires are the most unsafe bicycle tire on the market, trust me I have the injury scars to prove it

Care to share how you spilled, Johnathansss?

meanwhile

They could but it wouldn't help. You seem to think that rolling resistance is frictional; it isn't. It's the energy needed to bend the casing (and probably the filler with the airless tyre). And extra layer would increase this.

This is also why the folk belief that narrow tyres have to be faster is wrong.

I have to agree. They are dangerous. I put a set on with high hopes of avoiding flats about a year ago.
Last ride I took with them on the bike was a hot summer day and I was going pretty fast down a hill and hit a rough spot of asphalt and the front tire peeled partially off the rim. I almost lost control and took a header.
I slammed on the rear brake and as I slowed the tire miraculously kind of snapped back on. I stopped to check it. Just some scratches on the rim to polish out. I turned around and went right home...slowly and I'm riding my other bike and not this one again until I put pneumatic tires back on.

I could have been killed! I was doing about 30mph.

Schwalbe Marathon Tires are the truth, I bought them and so far so good, they sent 1 tire to me in a 5 foot by 2 foot box with a ton of paper in it, totally toooo much packing for one tire

Accident #1} I was coming down a hill at a red light going about 25 miles per hour, all the sudden the ****ing tire rolls off on me, luckily I had some quick reaction and caught myself and just got a bloody banged up knee, otherwise it coulda been worse. Total in my pedal biking experience in the past like 4 years, where I really hit it hard biking almost every day in place of driving(I just chose not to drive from the ages between 18-22, 22 my present age) I have been in 9 significant pedal bike accidents(not just pissy scapes i'm talkin ****ed up accidents) Accident #2} 1 accident came from going like 30 mph around a bend, bad idea I fell off smacked my face off a car, blacked out got life lighted, woke up in the hospital next morning they did x-rays, checked out A OK, woke the next morning after that I was slapped with a like $30,000 medical bill, luckily I did not make enough($10.00 per hour) so I was eligble for medical assistance, medical assistance picked almost all of the like $30,000 of that bill and I only had to end up payin $157, I hit a bump in the road once flew off my bike head first over the handle bars and hit my head making a bloody bald spot on my head with some fresh flesh wounds on my elbows and forearms, Accident #3} I went too fast around a bend fell off and hit the pavement pretty hard ripping some serious flesh off my elbow and calf, Accident #4} I was coming like 34 miles per hour down interstate 70 on the side and my brakes locked up on me and my front wheel started fishtailen and I ended up flying off leaving me with another bloody bald spot on my head flesh wound on my side & calf & knee & both forearms & both elbows and I bent 2 rims and my chain costing me like $400 in repairs since I have a like $930 dollar 30 speed disc brake carbon fork Ibex Corrida Ultimate and the thing is if I would of replaced my brake calipers and such when I seen that they wore not adjusting anymore then it would have saved me like $400 dollars and I ended up having to learn the hard way and replaced the brake calipers and such costing me like $150, Accident #5} I was up in a WalMart parking lot in Belle Vernon PA a city a little ways from me and it was dark and I did not see the road bump they had in the road so I was flying along like 25 miles per hour then all the sudden I hit the speed bump flew off my bike I had to stop my fall with my right hand spraining my wrist and as far as the flesh wounds I got from this accident they were so painful that it took like 5-6 hours before the pain would subside I had a casino chip size piece of skin ripped off of my left hand palm and ****ed up my elbow pretty painfully it was just like the Jackass stunt where the do the buggy race and fly right into a curb and fly off, Accident #6} I was coming down a road like 30 miles per hour and a car from a dealership was trying to pull out but was stuck in traffic(luckily for me) and yet again I shoulda addressed the brake issue sooner..... I didn't and smacked right into the side of the car flipping on top of the hood like a wrestler flys over the top ropes the dealership said the damage was just a few dings so they let it go and my bike had a bent tire rod that had to be replaced and I walked away limping, Accident #7} Brake issue yet again coming down a hill like 30 miles per hour I smacked into a parked car and bloodied myself up pretty nicely Accident #8} The most life and death accident thus far right here, I played russian roulet with a car I was coming to an intersection and a car was coming the other way I tryed to beat the car there it was dark the car probably did not see me and I beat the car just enough to where the car hit my back wheel only spinning my pedal bike vigorously and causing me to fall off which was another $120 like wheel replacement cost but the thing was if I woulda went a little bit slower I woulda been stone cold dead I was a second away from death it was CRAZY AS HELL Accident #9} I another crazy one was one time I was riding my pedal bike in the winter and the roads were icy and I had my studded tires on but this day my studded tires were not enough and I flew off my bike onto the side of the road luckily I had many layers of clothes with a coat which cushioned my fall cause I fell chest first on the ground knocking the wind out of me. In conclusion my 9 lives are up the next one could be death so don't go fast around bends, don't pedal bike at night without lights, watch for bumps in the road, in winter watch out for ice and make sure you got some good studded bicycle tires, if your disc brakes or v brakes cannot be adjusted anymore its time to change them or else, and airless tires = garbage

You sound like a lot of the people that diss airless tires.

You've never tried them but you read about someone who had a bad experience with them, so you jump on the 'diss wagon'.

What you don't know is that MOST people who have a bad experience ordered an inappropriate tire for their needs.

I have used several different airless tires, on recumbents, uprights and fixed gear bikes for about 10 years, with great satisfaction and have NEVER experienced, "Once they're on (which can be quite a chore) it feels sluggish and slippy."

JanMM

Can't bring myself to read this post but looking at the end of it you don't think much of airless tires, it looks like.

MilitantPotato

It is an account of all his different crashes (only one or two being while riding airless,) I think.

Purchased some tires last month from Airfree - Nu-Tech (700x28, 90PSI) against the better judgment of others. The tires weren't even made correctly. The support cords on one weren't molded into the tire all the way making it un-usable and the other has a hard spot that is so bad that the bike wants to come apart over about 12 MHP. Multiple E-mails, support tickets, calls and I received nothing in return. Visa wouldn't step in since I tried to give the supplier a chance to correct the defects and went over the 30 day time limit. Save your hard earned money for something worth having....

TRUMPHENT

I just replaced my tires with ones purchased from of all places, WalMart. Airless tires might have valid applications but, not on a bicycle. My solution to the "flat after flat" problem has been a Kevlar belted tire and a Mr Tuffy tire liner. My semi-worn Pasela TG's are now in reserve.

The new tires from Wally Mart are made by Innova, marketed by Bell. They are 700Cx35, folding and advertised with a kevlar belt beneath the tread. The box states the size as 700C x 32c-45c. I am not making this up. I couldn't see the size on the exposed portion of the sidewall until I unfolded it at home. My commuter is a cyclocross with 29r mountain bike wheels.

Frequent flats going into work are not acceptable. Solid tires are not acceptable. I can get the tires on and off the rims without tools. If I have a flat, I can get the bike back in motion very quickly with a tube change and CO2.

These tires cost me less than 14 dollars each. Kevlar belted and beaded commuter tires. That's my story and I'm sticking to it, for now.

Are any of you interested in penny farthings? You can't beat a rubber coated metal wheel.

yes

Have any of you flat prone people tried Stans notubes sealant? I've used them to convert mtb tires to tubeless. But, you can just buy the sealant. If you get tubes with a removable valve core - may have to drill the rims for Schrader, you could put the sealant inside a tube. That stuff works very well.

+1 Nu-Teck is a bad idea for a bicycle.

They don't seem to know how to make tires to their own specifications. I bought what they call 700x35 hyb, supposedly 90PSI equivalency as published on their website. My bike rode more like the tires were 60 PSI -- it was very unsettling to ride even 15 mph with the shimmy effect from both front and rear. I tried my best to believe it was the answer to flats but when the rear tire rolled off that was it. No more wishful thinking. These things are dangerous on a bicycle.

I purchased a set of Nu-Teck Airless Tires through their website. The tire size was 26 X 1 3/8 for an older 3 speed English bike. The tires arrived and although marked as the right size, were too small. This was confirmed by an experienced bike shop. I returned the tires and spoke to someone at Nu-Teck right before Easter 2011 and they agreed to resolve the problem and that was only because of the complaint I filed with Pay Pal. I foolishly took them at their word and let my complaint close. I have not heard from them since, the tires cost $87.00 and return shipping $13.00. I've contacted the Colorado Attorney General and Better Business Bureau all to no avail. At this point I'd be inclined to say Nu-Teck Airless Tires prove to be slippery whether you get to ride on them or not. Since then I've learned that tire sizing is not necessarily universal or at least with these 26" tires and I'm sure we could have overcome this problem even if we substituted pneumatic tires. Either way there is no excuse for fraud, Buyer Beware, especially when dealing with Nu-Teck.

I consider them out-and-out fraudsters. They know by now their product won't work and yet they continue to lie to customers and sell those POS things. They should be in jail.

Continental now has a similar design, and they even copied the "Plus" in the name:

Airless foams are high rolling resistance as a tire. ,
save for garden carts and trainer stand wheels.

For speeds up to 20 to 25 mph my Amerityres have preformed great! I have put 1,400 miles on one set with no problems. (also no accidents in the last 20 years) Pay attention to your rim width, depth and shape, these are not generic one size fits all! If they are the RIGHT size they CAN be a ***** to install!! As for johnathansassak, 9 MAJOR accidents in under four years? WTH are you a walking clusterf**k!? Who in their right mind would take advice from someone with that kind of record!

Lets see, when man invented the wheel it was stone, then wood, then wood with some sort of iron hoop on it and then wood or steel with solid rubber tires and finally the gods gifted mankind with aluminum and pneumatic tires. So, now in the 21st Century, we are going backwards with solid rubber tires, what is next, stone wheels? I suggest quartz monzonite instead of plain old granite, the higher quartz content should wear better.

Well, I guess we could revert to walking with some kind of animal skins wrapped around our feet.
