TAC 9 Tire, Tube and Rim Strip Combo Package for the old-school vintage 27×1-1/4″ (32-630) road bikes is the perfect solution for restoring or replacing the rubber to it’s original style and feel on your vintage steel road bike. Vintage steel-framed bikes have been a favorite among cycling enthusiasts and include brands such as; Schwinn, Peugeot, Fuji, Raleigh and others.
Unlike aluminum or carbon fiber bikes, steel absorbs impact energy created from rough roads and bumps. With the lighter framed alloys and carbon frames the impacts actually resonate through the frame and ultimately to the rider. With steel it is more dense and actually absorbs the shocks of impacts with little-to-no vibrations to the rider. Therefore, the steel frame is a favorite among urban and commuting riders.

Here you will discover overlooked procedures and situations when changing a bicycle tire and/or inner tube. Most people take for granted what it takes to safely and properly inflate a tire from a complete flat. We always suggest taking your bike to a professional mechanic or bike shop for any repairs.
INSPECT: It’s imperative that you inspect your tire and rim before installing your new inner tube. A puncture can occur due to a sharp object protruding through the tire, a damaged tire or if the rim strip on the rim is worn or out of place and not providing protection from the spoke nipples against the inner tube.
Step 1: Inflate bad tube: With the defective tube removed from the tire add enough air to detect where the hole may be. An inner tube can expand much bigger when it’s outside the tire. By identifying where the leak is can help you identify where the puncture occurred in relation to the rim or tire. Then you can put more emphasis on inspecting that region of the tire or rim.
Step 2: Tire Inspection: Sometimes when a thorn or sharp object punctures a tire it can break off leaving a sharp end protruding inside the tire but not visible on the outside. Without verifying the inside of the tire is free from debris there is potential for a sharp point to puncture your new tube. CAREFULLY run your fingers around the inside of the tire to ensure there are no sharp objects protruding to the inside. Inspect the outside of your tire for any obvious holes, tears or a damaged bead.
Step 3: Inspect Rim Strip: Rim strips protect the inner tube from the spoke nipples in a single-walled rim or from the holes in a double-walled rim. Rim strips can be made of rubber, cloth or vinyl. On a single wall rim it is recommended to use the rubber rim strip but a cloth rim strip with adhesive will work too. On a double wall you can ONLY use a cloth or vinyl rim strip since it provides more rigidity over the spoke holes. Rim strips vary in size and are usually measured in millimeters. A rim strip should be the width of the bottom inside of the rim and not too wide to interfere with the tire bead hooking onto the rim.
Step 4: Tire Inflation: VERY IMPORTANT STEP! This is where most failures occur by do-it-yourselfers, they POP an inner tube during inflation. Here is why. The tire is designed to “hook” or “bead” onto the rim and in technical terms it’s called a “clincher”. Sometimes a small area of the tire will not hook all the way onto the rim and as air pressure (PSI) increases the inner tube is filling every area it can get into inside the tire and rim. The inner tube is looking for any paths or voids it can find until it can’t find anymore. At this time the tube literally cannot stretch any further even though air pressure is still increasing. However, if the tire didn’t get a complete hook/bead on a small section of the rim the inner tube will push on it until the tube finally slips out where the tire wasn’t completely beaded to the rim. When this happens there will be very loud POP and you will see a huge tear in the inner tube. Some say the tube failed and “split at the seam”. Tubes do NOT have seams. They have mold lines that appear to be seams but they are not. Anyway, a tube literally cannot just POP from inside of a tire. It has to have an escape route like a hole or tear in the tire. But in this case the “escape route” was between the tire and rim due to the bead not hooking completely on the rim. Furthermore, there have been many instances of a tube literally popping while the bike is parked or after the first few miles. The reason for the delay is because the tire was beaded enough initially but since it wasn’t completely beaded it finally slips out a period of time after installation.
-HOW TO PREVENT A TUBE POP: Inflate incrementally and cautiously! Add 15psi and inspect the tire bead to rim all the way around AND on both sides. You’ll see a mold line on the tire you can use as a reference to the rim for an even and complete bead. If it looks good then inflate to 25-30psi and reinspect. If there is a section not completely beaded then release some air and push the tire bead into the rim until it is even. Once you have an even bead after the 30psi check you should be a go for full inflation to the TIRE’s recommended pressure rating. Then do another inspection all the way around and on both sides. An inner tube can only expand to the volume of the tire. The tire & rim are the only limiting factors for pressure.
If you do pop a tube or feel the tube was defective we will replace it free of charge. Simply message us via your order in your Amazon account so we will have your order ID.

Kenda K35
27 x 1-1/4″
ISO/ETRTO: 32-630
Maximum Pressure: 90psi
Be sure to verify the ISO/ETRTO (32-630) on the side of your old tire. This is the most important specification when finding a replacement tire for any bicycle wheel.
What is the ISO or ETRTO?
ISO (International Standards Organization) are standards that engineers use in designing and manufacturing everything.
ETRTO (European Tire and Rim Technical Organization) is the European standard for pneumatic tires and wheels. The worldwide bicycle industry now uses it as the standard for tires and wheels.
ISO/ETRTO: 32-630
32 is the width in millimeters
630 is the diameter in millimeters. The 630 is the most important number because it decides if the tire will mount on the rim. The tire and rim must be the same dimension.
27 x 1-1/4″ TAC 9 Inner Tube 32mm Schrader Valve
TAC 9 bicycle inner tubes are quality high pressure tubes manufactured with quality butyl rubber.
27 x 1-1/4″
Schrader Valve, 32mm length (1-1/4″)
Reinforced Valve Stem
Removable Valve Core – Tube sealant can be added.
High Pressure, can withstand the pressure rating of any tire.
Rim Strip, 13mm Rubber
Rim strips protect the inner tube from the spoke nipples on the rim. Without a rim strip, or one that is in bad condition or not properly in place, the inner tube will form around the nipple and thin making it very vulnerable to failure at that point. Eventually it will fail if not properly installed. We recommend with any tire replacement that you also replace the rim strip.
Rubber
27 x 1-1/4″ diameter
13mm wide (1/2″)
Packaging, Why Twist the Tires?
We package TAC 9 Tires in a twisted manner which reduces the package dimensions in half. In no way will it harm the tire or the steel bead. By reducing the size of the package it will reduce the cost of the delivery carrier in half due to dimensional weighting calculations. This in turn keeps the retail cost much lower!
