3.00-4 Inner Tube Razor E300 - Premium Heavy Duty 260x85 Replacement Mobility Scooter Tire Tube - Perfect for Razor E300 Scooter, Pocket Rocket, Utility Dolly, Hand Truck 3.00 x 4 Angle Valve Tube (1)

The tubes were a perfect fit and easy to install. The big question, of course, is how long they will last. They replaced the original tubes which were quite under used before both went flat due to air leaking from base of both of the valve stems. Will these new tubes last any longer?....only time can tell for certain.

Good quality inner tube... fit and function are perfect for the application.

Perfect fit

Tube works great, had to spend time installing. After I found out that I could have bought tire and tube for a price lower than just the tube I purchased.

A classic, modern, battleship-gray tire, it leaves no marks on the marble floor. When filled with air, the ride is smooth and supple as it rolls over the small objects that might fall in its way. This has made my mobility scooter a pleasure to ride as I survey my acreage on fully inflated tires. What was once immobile for years and years is now mobile again thanks to this marvelous little, almost insignificant item. I would recommend it to all of my mobility challenged friends to buy this tire.

Good tires

The tube is fine. It's the right replacement product and it fixed the problem with the flat. You would not believe how challenging it is to replace the rear tube on a Razor. Set aside some time. Set up a work bench. Watch every You Tube video you can, dive in and watch your calendar's pages flip. One helpful hint: Inside the right handlebar grip is a tire valve extender you'll need to fill this tube with air after your installation is successful. I wish you no extra parts resting on your work bench when you finish.

Here's the situation,I had to replace the tube on the 2 piece hub for the wheel of my portable generator. After I delt with hurricane Irma, and had enough time to catch up on everything important, I found that after I double checked my email I received 4, yes 4 emails from a representative named James. He literally sent them or they were auto sent within 1 week. I didn't even have enough time to give a fair and impartial review on this item, because it appeared it's more important for them to get numbers instead of honest reviews. Sure the tire is no longer flat, but I also have not gone off-road with the generator or rode it up the street to see if it can handle the load. Give buyers a chance before pestering them to the point that they just give a review on your actions instead of the product.
