Q31: Range of aspect ratio for high molded tyres - Tractor Design Principles - Farm Machinery and Power Engineering- ICAR JRF/SRF 2024 | Agrigyan

• Pneumatic Tyre Aspect Ratio Classifications:
• Aspect Ratio ($AR$) of a tractor tyre is the ratio of section height ($H$) to section width ($W$) expressed as a percentage or fraction ($AR = H / W$):
• Low-section (low-profile) tyres: $AR \lt 0.75$
• Standard agricultural tractor tyres: $AR = 0.80 - 0.85$
• High-molded (tall-profile / high-aspect) agricultural tyres: Have tall, narrow carcass sections designed for high ground clearance and crop row spacing where $AR \ge 1.00$ (1.00 or higher).
• Conclusion: 1.00 or higher (Option 4).

Correct option: (4) 00 or higher
