HIGH TIRE SCRUB
2 Double Axle (Tandem)
- Typical Capacity: 10k – 14k lbs
- Tire Scrub: Minimal
- Maint. Cost: Low (4 tires)
- *Best for Tiny Homes under 28ft. Easy to pivot into tight spots.
3 Triple Axle
- Typical Capacity: 18k – 21k lbs
- Tire Scrub: High
- Maint. Cost: High (6 tires)
- *Necessary for heavy builds (30ft+). Tracks straight on highways but fights you in parking lots.
What is “Tire Scrub”?
Trailers don’t have differentials or steering axles. When you turn, the trailer pivots around the center axle. The axles in front and behind are forced to drag sideways across the pavement.
Triple Axles have a longer wheelbase, creating severe drag (scrub) on the front and rear tires during tight turns, which can pop tires off rims or bend spindles if turning too sharply on pavement.
