AR-PRO 170/80-15 Replacement Inner Tubes (2-Pack) — PV-78 Valve, Heavy-Duty Butyl

AR-PRO 170/80-15 replacement inner tubes (2-pack) are heavy-duty butyl tubes with PV-78 valve stems designed to fit 170/80-15 tires for durable, reliable on-road and off-road use.

These AR-PRO inner tubes are engineered for riders who need a dependable, long-lasting replacement that keeps air pressure stable and handles rough surfaces without frequent repairs. Manufactured from premium butyl rubber and fitted with PV-78 valve stems, this twin pack provides two ready-to-install tubes that match the sizing conventions of 170/80-15 tires used on many cruisers and power-sports bikes.

Will these inner tubes fit my 170/80-15 tire?

Yes — these tubes are sized specifically for 170/80-15 tires and follow standard inner-tube sizing rules, so they pair correctly with tires labeled 170/80-15. Proper fit depends on correct rim width and tire construction, so confirm your wheel specs before installation.

• Size designation: 170/80-15 for tires that match this numeric designation.
• Valve type: PV-78 valve stem suitable for common rims and pumps.
• Works with: most passenger and power-sports rims within compatible width ranges.

How durable are these tubes on rough roads and trails?

Constructed from premium butyl rubber, the tubes emphasize air retention and puncture resistance versus cheaper materials. While no inner tube is puncture-proof, AR-PRO’s heavy-duty build provides improved resilience to impacts and small abrasions encountered in daily riding.

• Material: high-quality butyl for better airtightness and flex.
• Reinforced valve area to reduce leaks where tubes often fail.
• Designed to absorb impacts and resist pinching during normal use.

How easy is installation and maintenance?

Installation is straightforward for anyone with basic tire-changing experience: deflate and remove the wheel, take out the old tube, slightly inflate the new tube to avoid pinches, and seat the tire before fully inflating. Regular checks for proper pressure and visual inspection after off-road rides will help maintain tube life.

• Included: two inner tubes ready to install.
• Tip: inflate slightly when seating to prevent pinching between rim and tire.
• Maintenance: check valve stem and pressure periodically for optimal performance.

What tools or accessories do I need to use these tubes?

You’ll need basic tire tools and a pump compatible with PV-78 valve stems; a set of tire levers and a pressure gauge make installation safer and more accurate. For roadside repairs, carry a patch kit and a portable pump as backups since butyl tubes can still puncture in extreme situations.

• Necessary: tire levers, rim-appropriate pump or compressor, pressure gauge.
• Recommended: patch kit and portable hand pump for emergency repairs.
• Valve compatibility: PV-78 works with most standard pumps and adapters.

Who is this for: Riders who own motorcycles or power-sports machines fitted with 170/80-15 tires and who want a reliable, value-packed spare or replacement. The AR-PRO 2-pack is ideal for commuters, weekend cruisers, and hobbyists who prefer the improved air retention and durability of butyl inner tubes. Choose this set if you want straightforward installation, durable construction, and the convenience of two tubes for longer rides or faster turnaround between flats.
