4.00-8 Motorcycle Tire

4.00-8 Motorcycle Rear Tire — Factory-Direct, Tube Type, OEM Available

The 4.00-8 is one of the most widely used rear tire sizes for two-wheeled motorcycles running in demanding daily conditions — from urban delivery routes to rough rural roads across Southeast Asia, Africa, and Latin America. At JABIL's Shandong factory, every 4.00-8 rear tire is built with a reinforced nylon carcass and a wear-resistant tread compound, engineered for high load capacity, stable grip, and long service life at an economical cost.

Product Specifications

Core Parameters

Applications

Daily commuting & delivery motorcycles. As a rear tire, the 4.00-8 carries most of the rider and cargo load. Its deeper tread grooves and stiff shoulder design resist uneven wear caused by frequent stops and heavy saddlebags — a common pain point for delivery fleets.

Rural and rough-road riding. The reinforced carcass and cut-resistant compound handle unpaved village roads, gravel, and debris where pneumatic tires often fail prematurely. Operators in Southeast Asia and Africa choose this size specifically for its toughness-to-price ratio.

Hot climate markets. The tread compound is formulated to stay stable at sustained high temperatures, reducing heat build-up on long highway stretches — a key factor in tire life across tropical markets.

Customization Options

As a direct manufacturer, JABIL supports OEM production of the 4.00-8 rear tire: custom tread patterns, compound tuning for specific road conditions, private-label branding, and custom packaging. Minimum order quantities are flexible, and mixed loading with other sizes (2.75-17, 3.00-18, inner tubes, flaps) helps distributors optimize container space.

Quality Control

Every batch passes a three-stage inspection before shipment:Raw material testing — imported natural rubber and carbon black verified against batch specsIn-process control — carcass stitching, calendar accuracy, and curing parameters monitored per tireFinal inspection — appearance, dimensional tolerance, and hardness sampling before packing.

Case Study

Case Study 1: Cambodia — Motorcycle Dealer Reduced Customer Returns by 35%

Client: A motorcycle tire dealer in Phnom Penh supplying 20+ repair shops across the city and surrounding provinces.

Challenge: Previous budget tires were failing within 2 months — sidewall cracks on hot roads, premature tread wear, and frequent punctures. Customers were returning to shops demanding replacements, damaging the dealer's reputation.

Solution: Switched to our 4.00-8 Semi-Block 6PR TT with matching butyl inner tubes for the majority of commuter riders. Added 4.00-8 Block 8PR for rural/provincial riders on rough roads.

Results after 6 months:

● Average tire lifespan: 2 months → 4.5 months (6PR Semi-Block)

● Customer returns/complaints dropped by 35%

● Repair shops began recommending the dealer's tires specifically

● Monthly order volume grew from 200 pcs → 350 pcs

"Before, my customers always came back complaining — tire cracked, tube popped, tread gone in two months. Now they ride 4-5 months without issues. The shops trust my brand and my orders keep growing." — Tire Dealer, Phnom Penh

Case Study 2: Nigeria — Moto Taxi Operator Cut Monthly Tire Costs by 28%

Client: A moto taxi (okada) operator in Lagos running 30 bikes, each carrying 1–2 passengers for 80+ km daily on mixed urban roads — potholed asphalt, sandy side streets, occasional unpaved shortcuts.

Challenge: Okada riders are the toughest test for any tire — heavy loads, long hours, rough roads, heat. Previous 6PR tires were wearing through in 2–3 months, and punctures were a daily occurrence causing lost revenue from downtime.

Solution: Upgraded rear tires to 4.00-8 Block 8PR TT with butyl inner tubes. The 8PR's reinforced sidewall handles heavy passenger loads, and the Block pattern provides grip on Lagos' unpredictable road surfaces.

Results after 4 months:

● Tire lifespan: 2.5 months → 3.5+ months (8PR Block)

● Puncture incidents: daily → less than 1 per week per bike

● Monthly tire replacement cost per bike: reduced by 28%

● Downtime from tire issues: virtually eliminated

"Okada work destroys cheap tires. The 8PR Block is the first tire that actually lasts under real Lagos conditions — heavy passengers, bad roads, sun and rain. We've standardized it across all 30 bikes." — Operations Manager, Lagos Okada Fleet

Case Study 3: Philippines — Tricycle Delivery Fleet Upgraded to Tubeless for Zero Downtime

Client: A motorcycle delivery service in Cebu operating 20 bikes for parcel and food delivery, 60–100 km daily, mostly on paved urban roads.

Challenge: Tube-type tires with inner tubes meant frequent pinch flats (tube punctures from road impacts). Every flat = 30–60 minutes downtime = delayed deliveries = customer complaints.

Solution: Converted to 4.00-8 Rib 6PR TL (Tubeless) for all rear wheels. No inner tube = no pinch flats. Small punctures seal automatically rather than causing instant deflation.

Results during 3-month peak delivery season:

● Flat tire incidents: 4–5 per month (TT) → 0.5 per month (TL)

● Downtime per flat: 30–60 minutes → 0 minutes (slow leak, not sudden blowout)

● Delivery delays from tire issues: eliminated

● Rider confidence: dramatically improved — no fear of sudden flats during rush hours

"Tubeless changed our operation. Before, a flat meant a stopped delivery and an angry customer. Now, even if we get a small puncture, the tire holds air long enough to finish the route and swap at the shop. Zero complaints." — Delivery Fleet Manager, Cebu
