I have an Oglaend DBS Sport bike that needs new tires. There are 26 x 1.50 tires on the rims currently,but I tried to put a used 26 x 1.5 on and it will not fit. Too tight. What size tire should I get and where? Thanks, Paul

talk this over with a bike shop that sells rims and tires
there are several things to consider
ride characteristics change dramatically with different tire widths
legal ramifications of different front and rear tires
real advantages of wider tires as against "looks cool"
costs of new rim and wider tire against standard tires
modification plates for the wider tire
Talk it over with an accredited bike shop and find a person that has real experience and not just a salesman

Remove rear wheel from bike. Deflate tube by removing valve stem. Tire should remove easily by pulling rim of tire over the rim. IF difficult, take to local bike shop for assistance

Sue, there are lots of how-to videos out there about this. Just google "How to change bike tube" or tire, or flat. You have to remove the wheel, which is easiest with TWO wrenches - they can be the adjustable "Crescent" wrenches, but don't use pliers. You also have to remove the small screw that holds the fat little L-shaped lever to bike. Use a rag to remove the chain from the cog on the wheel. Then use the little "Tire irons" to remove the tire from the rim and get the old tube out - these come three to a set, the plastic ones are best, and you can get them at K-mart. Also, use some baby powder (talc is better than cornstarch) to make the new tube easier to position correctly in the tire - sprinkle the powder inside the tire when you have if off and put the tube in the tire before you put the tire back on the rim. It helps if you put a little air in the tube to make it a nice sausage first. And make sure you get the valve stem straight and pulled all of the way through the hole in the rim. Be very careful that you don't pinch the tube against the rim when you put the tire back on. And the hardest part might be getting a pump to hold tight onto the valve stem - using compressed air (like at a gas station) is by far the easiest method. Good luck.

Hello, there is really no problem what pattern is on the tread, you only run into problems by changing sizes. There is a really good tire sizer in the Discount tires.com site. You use some of the tools in the site and you can find out what you can use on the rims you have if you want to change sizes.

They also have a MPH calculator which will tell you about the speedometer error from changing tire sizes. The All-Terrain tires have wider grooves on them and will tend to be nosier than All-Season tires. You can also save some money on buying tires with the proper Speed rating for your vehicle.
The faster the speed rating, the more expensive the tire.

You should check your current tires and look at the speed rating for them, it will be on the sidewall. You would want the same or better as your stock tires. Watch for the load rating too!
Everybody has an opinion on Brands and surprisingly, some Brands make a great tire in one size and the same Brand, same Tire type, can be lousy in another rim size. Ford puts All-Terrain tires on some vehicles, just go to a New car lot and look at what they are installing on the new models.

its somewhat hard to explain in words

also most bike stores will probably help you out for free

Can you explain why you think the tires are too big? Do they NOT fit the rims? What condition was this bike in when you bought it? If the brake pads line up with the rims then the wheels are correctly sized for the frame.

You have to remove the entire wheel from the bike. Then change it just like you'd change a front tire... remove oneside of the tire from the rim, pull out bad tube, clean rim, put in new tube, put tire back on rim, inflat tube... good to go. There are 1,000,000 videos on YouTube to show you this process.

Inner tubes commonly lose air when stored for as little as a couple of months and quicker when cold. They also tend to dry out and leak as fast as you can pump. Replacement tubes are available at bike shops and even less than $6.00 bucks at Wal-Mart.

To replace(The long version,cause the short version not good):
Remove wheel from bike, trike, trailer, etc. and deflate tube completely. You will need 2 box end wrenches (the ones with the closed ends, because these are not sharp). Insert box end of wrenches next to each other between rim and and one wall of tire, now pry the wrenches back so as to pry one wall of tire to the outside of rim, now alternatingwrenches, slide wrenches away from each other to slowly walk one wall of tire outside of the rim, reach in and grasp old tube and pull it out. Now straight new tube out remove plastic fill cap(put cap in your pocket), reach in and insert filler into hole in rim, now working your way around with your fingers to push tube up into tire(carefull not to let it get twisted), now put cap back on tube so you don't loose the filler, now work your way around with your fingers to push tire back into rim, you may need to use the box end of the wrenchto help pry the last bit of tire back in(Just don't pinch the tube between wrench and rim while doing this, lest you now have a new hole to fix), now grasp filler so you don't loose it, add air to amount shown on tire, and RIDE ON!

Try warming the tire up. Put it in the tub with super hot water it will make it stretch easier. I did this with a twelve inch kids bike it worked sweet.
