AR-PRO 170/80-15 Inner Tubes 2-Pack — Heavy-Duty Butyl Rubber with PV-78 Valve Stem, Reinforced Walls

These AR-PRO inner tubes are built for riders who need durable, high-quality replacements that restore tire function quickly. Made from premium butyl rubber and fitted with a PV-78 valve stem, the pair is sized specifically for 170/80-15 tires. Whether you keep a spare for the road or need dependable tubes for daily use, this set balances strength, flexibility, and ease of use.

How durable are these inner tubes for everyday riding?

The AR-PRO tubes use heavy-duty butyl rubber known for strong air retention and resistance to repeated flexing. They’re designed to withstand typical road and light off-road impacts without prematurely sagging or blistering.

• Premium butyl compound for long-term air seal.
• Reinforced wall thickness to resist pinch flats.
• UV- and ozone-resistant materials to reduce aging.

Will the PV-78 valve stem fit my rim and pump easily?

The included PV-78 stem is a common straight valve size compatible with most motorcycle and power-sports rims that accept this valve type. Its profile allows quick inflation with standard air tools and hand pumps that accommodate PV-style stems.

• PV-78 valve stem for wide pump compatibility.
• Secure valve seating to minimize leaks at the rim.
• Threaded cap interface for easy tightening and protection.

How do these tubes perform during installation and maintenance?

AR-PRO inner tubes are manufactured to consistent dimensions so installation is straightforward: partially inflate to remove twists, position inside the tire, then seat and finish inflation. The butyl composition simplifies repairs and patching if needed.

• Pre-sized for fast, no-fuss fit in 170/80-15 tires.
• Flexible enough to avoid pinching during mounting.
• Patch-compatible for field or shop repairs.

What advantages do I get from a 2-pack instead of a single tube?

Buying a 2-pack gives immediate backup coverage so you’re prepared for a second failure or can replace both tubes at once for matched performance. It’s cost-effective and reduces downtime compared with buying tubes individually.

• Extra tube stored as an emergency spare.
• Matched-age replacements for consistent handling.
• Better value per tube compared with singles.

Who is this for: Riders and mechanics who need dependable replacement tubes for 170/80-15 tires — including commuters, leisure riders, and light off-road enthusiasts — will appreciate AR-PRO’s balance of durability and value. If you run tires of that size and want a plug-and-play tube with PV-78 compatibility, this two-pack is tailored to keep you rolling with minimal fuss.
