Sunlite Standad Schrader Valve Tubes, Multiple Sizes

I used to live in South Florida and rode my bicycle about 5,000 a year. These tubes are a great price and easy to replace. Make sure you (1) inflate the tube just enough to give it form before putting inside the tire to prevent kinks and find and remove any obstruction that might have pierced your tire, or it will puncture the next tube. Many blame the tube, but the tire have most to do with getting flats. I make it a point to purchase Kevlar or the best puncture proof tire around, as the purpose of the tube just to hold the air, not prevents flats. That's the job of the tire.

I bought many of this brand and they all leaked immediately. I then bought shwinn tubes and that solved it.

This tire tube is perfect for my 700Cx35mm bike that I have gotten from big 5 probably 2 years ago and this tire tube did its job to allow my bike to be up and working again. I paired this tire tube with a Kenda tire 700x35mm as well and these perform together effortlessly.On my first try in inflating the tire there was a bump that had occurred on a certain part of the tire but after deflating it and inflating again slowly while slapping the tire to spread out the rubber tube it inflated just fine.I ended up testing the tire with the tire tube and it went perfectly. Even went out to try the bike for a short while as well and it works.Overall, it's a good tire tube that is cheap and did the job well. There isn't any special features such as self heal but for a cheap price I couldn't complain. It was also hard to find just a typical valve for bike tubes since I am a student that uses the bike to commute but this tire tube provided me with a schrader valve which is the classic hike used to fill the tire tube with air.

Tube appears to be of good construction, except the 32 mm shraeder valve, while a common length, is too short for some deep welled wheel rims. To pressurize the tube, I had to use a metal valve extender, since otherwise there aren't enough threads of the valve stem exposed for the pump to grab it to form a seal (even while holding it up by firmly depressing the tire against it), at least until mostly inflated. Measure your existing valve stem first, many will be better off with a 40-48mm length valve.

I have ridden thousands of miles on Sunlite brand tubes. The ones I'm reviewing today are lightweight. One of these did recently fail on me, however there was a hole in my tire that corresponded to the hole in the tube (it is very clear to me that the failure was due to debris and not the tube's fault).Match the tube you buy with the riding you do. The tubes I'm reviewing here are light, I ride them on roads and paved bike paths where there is not much debris, in these conditions I rarely experience flats.If you experience flat tires a lot, Sunlite does make other tubes that may fit your need. For Example, when I lived in Nebraska where flats due to thorns were common I ran Sunlite thorn resistant tubes (these cost about twice as much, and are quite a bit heavier). On many occasions I stopped and waited for my friends to fix flats caused by thorns without ever having a flat myself. In fact, after around 2000 miles of riding Sunlite Thorn Resistant tubes in an area known for thorns I experienced two flats, (1) a 16D nail that my tire picked up on the edge of a rural road, and (2) a broken spoke that was pushed down through the inside of the tube. Please note, my mention of thorn resistant tubes is for illustrative purposes. The product I'm reviewing is not thorn resistant.I've yet to have any brand lightweight tube last more than about 500 miles in the rear when riding 'unprotected' (light tire, light tube, no insert). Flats are a fact of life for the 'more than casual' rider. The tubes I'm reviewing do fall to the higher end of that 500 miles. If these tubes can run 500 miles with me riding on them (I'm a big/'Clydesdale' rider), then I don't think quality is an issue at Sunlite.Finally, if your tire goes flat within 24 hours of replacing the tube, you probably did something wrong. Here are some tips, learned through my experience, and the experience of those I've ridden with, that might help.1) If your rim requires one, make sure that the protective strip (usually this is a big rubber band with a hole in it where the stem goes through) is in place before you put the tube/tire back on.2) Prior to repairing a flat, run your fingers around the inside of your tire, whatever popped your last tube may still be in there (or still embedded in the tire wall/tread). Note, whatever popped your tube is probably at-least a little sharp, use appropriate caution when feeling out the inside of your tire.3) When the situation allows, a little powder inside the tire, or rubbed onto the tube, can help avoid pinch-flats. I also like to inflate the tire to about 20 PSI and then bounce it around some to help the tube settle into place before heading for full pressure.4) Don't over-tighten the nut that holds the stem in place, and make sure the stem is not sticking out at an angle before you fully inflate the tire.5) If you're on the trail, be careful with your trail pump, pushing back and fourth on the stem while you pump can damage the tube, or even your rim.

Good quality tube easy to install.

Outstanding price

I've used these tubes in the past with no issues. The last set I received lasted less than an hour. Never rode the bike. Tubes developed a leak after installation while the bike was stationary. I actually heard the tube pop and air leak out. I installed a different brand and no issues.

Bought this to fix my daughter's bike, seemed good until i inflated it. On the wheel its says 40 to 65psi, when it got to 45 it popped like a baloon. Asking for a refund!
