LUOCHENGHUA 3.00-4 Inner Tube
Fits recreational gas and electric scooters and other applications using 3.00-4 tires. Best for Razor E300, E325, and similar pocket rockets or mini quads. The curved valve stem supports easy inflation in tight wheel wells. Choose this if you need a straightforward, widely compatible 3.00-4 tube for common Razor models. Caution: verify the exact model compatibility beyond listed Razor series to avoid a loose fit.
AR-PRO 12.5 Inch Inner Tubes (2-Pack)
Universal tubes for 12.5″ tires, including 12.5×2.5, 2.75, and 3.0 tires. Best for Razor Pocket Mod and similar 12.5″ scooters, Schwinn GT, Currie models. The TR87 angled valve stem facilitates inflation in tight spaces and reduces bending risk. Choose this if you need a compact, two-pack option for multiple scooters or dirt bikes. Limitation: not suitable for non-12.5″ wheel sizes beyond listed ranges.
FVRITO 4.10-6 Inner Tube (Set of Two)
4.10-6 NHS size, compatible with 6-inch rims used on go-karts, small ATVs, quad bikes, and lawn equipment. Best for heavy-duty use where durable rubber and a robust valve stem are preferred. The bent valve stem aids inflation in restricted spaces. Limitation: double-check fit for non-standard 4.10-6 configurations to avoid mismatch with 4.50-6 or 5.30-6 tires.
RUTU 18×8.50-8 Inner Tube (2-Pack)
Universal fit for 8″ rims used on ATVs, mini bikes, and garden equipment with tire sizes like 18×8.50-8 and 19×7-8. Good air retention due to butyl rubber, offering longer hold times between top-offs. Best for riders seeking longer inflation stability and broader compatibility. Caution: confirm tire exact size and rim compatibility since this is a universal fit and may not match every 8″ tire variant.
JIAYAN 110/50-6.5 Inner Tube
Replacement inner tube for 47cc/49cc mini pocket bikes and 50cc mini quads with 110/50-6.5 or 90/60-6.5 sizes. Best for small-pocket bikes that need a reliable TR87 angled valve stem for easier inflation. Choose this if your model uses 110/50-6.5 tubes and you want a two-pack option. Limitation: ensure your tire size exactly matches 110/50-6.5 or 90/60-6.5 specs to avoid a poor fit.
Buying Guide
What size do I need? Start by checking the tire size printed on your tire sidewall. Common mini quad sizes include 3.00-4, 4.10-6, 12.5×2.5/2.75/3.0, and 18×8.50-8. Confirm the tire width and rim diameter to select the correct tube.
Valve type matters. Angled TR87 valves fit better in tight wheel wells; curved valves are easier to inflate in awkward angles. For high-inflation reliability, choose butyl rubber tubes for longer air retention.
Should I buy a pack? If you own multiple machines or anticipate replacements, a multi-pack (2-pack) offers value and readiness for future repairs.
Durability and application. Heavy-use environments (lawn equipment, go-karts) benefit from thicker NHS tubes with bent stems for space-constrained rims. If your use is light, standard tubes will usually suffice.

- What is the most common mini quad inner tube size?
3.00-4 is common for smaller pocket quads, while 4.10-6 fits many lawn and go-kart wheels. - What is TR87 valve stem?
TR87 is a bent valve stem design that eases inflation in tight spaces and reduces valve bending during use. - Are butyl inner tubes better?
Butyl tubes offer better air retention and durability than traditional rubber tubes, reducing the frequency of reinflation. - Can I use a scooter inner tube in a go-kart?
Yes, if the tire size matches (rim diameter and width). Always verify the exact size before purchasing. - Is a two-pack worth it?
For owners with multiple machines or frequent repairs, a two-pack provides cost savings and readiness.
