Cushion vs pneumatic tires: traction, comfort, and capacity
Tires are central to performance and safety, and they influence whether electric forklifts or IC forklifts make sense for your site.
- Cushion tires
- Profile: Smooth, solid rubber bonded to a steel band
- Best for: Smooth, dry indoor floors and tight turning radius
- Pros: Smaller turning circle, lower chassis height, typically lower cost
- Cons: Limited traction on rough/uneven or wet surfaces; lower ground clearance
- Typical truck classes: Class I (electric sit‑down, cushion), Class IV (IC cushion)
- Pneumatic tires
- Profile: Air‑filled or solid pneumatic; larger diameter
- Best for: Outdoor, uneven, or debris‑laden surfaces; ramps and gravel
- Pros: Better shock absorption, traction, and ground clearance
- Cons: Air‑filled versions risk punctures; solid pneumatics cost more but reduce flats
- Typical truck classes: Class V (IC pneumatic); many electrics now offer pneumatic or solid pneumatic options
Pro tip: Don't mix tire types on the same axle. If your facility spans indoor smooth floors and outdoor yard work, consider dual‑fleet (cushion inside, pneumatic outside) or electrics configured with pneumatic/solid pneumatic tires where appropriate.
Total cost of ownership (TCO): where money is really made or lost
While sticker price matters, TCO usually decides the winner.
- Upfront costs
- Electric (lead‑acid): truck + battery + charger + battery room equipment
- Electric (lithium‑ion): truck + Li‑ion pack + high‑rate charger; higher upfront but efficient
- IC: truck + initial fuel storage/equipment; generally lower upfront
- Energy/fuel
- Electric: kWh cost × usage; potential off‑peak rates and demand management
- IC: LPG/diesel price × gallons consumed; volatility can swing costs quickly
- Maintenance
- Electric: fewer moving parts; lower planned maintenance; Li‑ion reduces battery maintenance
- IC: engine, transmission, exhaust/aftertreatment (diesel), coolant, oil, filters
- Labor and uptime
- Multi‑shift electric strategies: battery swap vs opportunity charging; choose policies to avoid downtime
- IC uptime is simple with spare fuel cylinders or on‑site tanks
- Incentives and sustainability
- Utilities and local governments may offer rebates for electrification
- Emission reductions can support ESG goals and customer requirements
- Residual value
- Condition, hours, and battery health (for electrics) heavily influence resale
Which should you choose? A simple decision framework
- Mostly indoors, 1–2 shifts, tight aisles, food/pharma, cold storage, or air‑quality concerns → Electric forklifts
- Multi‑shift with short breaks, need minimal runtime planning, outdoor weather exposure, rough yards → IC forklifts
- Mixed indoor/outdoor: Consider electric forklifts with pneumatic/solid pneumatic tires; otherwise a split fleet
- Heavy loads and attachments: Check residual capacity charts; IC forklifts often favored outdoors, but heavy‑duty electrics are increasingly viable
- Limited electrical capacity or no space for charging/battery rooms → IC forklifts or lithium‑ion electrics with fewer chargers and opportunity charging
- Strong sustainability targets and noise reduction goals → Electric forklifts
Battery choices for electric fleets

Forklift comparison FAQs
- Are electric forklifts powerful enough for heavy loads?
- Yes for many indoor applications up to common capacities around 12,000 lb; heavy‑duty electric models exist for higher ranges. Always check the model's capacity and residual capacity with attachments.
- How long do electric forklift batteries last?
- Lead‑acid often supports a full shift per charge with proper sizing; lithium‑ion can run multi‑shift with opportunity charging. Battery lifespan depends on cycles, charging practices, and environment.
- Can electric forklifts work outdoors or in the rain?
- Many are rated for outdoor use with appropriate enclosures and pneumatic or solid pneumatic tires. Confirm the IP/weather rating and avoid standing water.
- Is propane cleaner than diesel indoors?
- Propane generally produces fewer particulates than diesel, but both create emissions that require ventilation and monitoring indoors.
- Cushion vs pneumatic tires: which should I choose?
- Cushion for smooth indoor floors and tight maneuvering. Pneumatic or solid pneumatic for rough, uneven, or outdoor conditions.
- What if I run three shifts?
- IC forklifts are easy to refuel quickly. For electric fleets, choose lithium‑ion with opportunity charging or plan lead‑acid battery swaps and charging infrastructure.
