Tyre Safety FAQs: Uganda Edition
Clear, practical guidance for road users. Follow your vehicle manufacturer’s instructions and consult a qualified tyre professional whenever a tyre may be unsafe.
1. How should I check and care for my tyres?
Check the inflation pressure of every tyre, including the spare, at least once a month when the tyres are cold (the vehicle has been parked for at least three hours). Also check before a long journey or when carrying a heavy load. Use a reliable pressure gauge and follow the vehicle placard or owner’s manual—not the maximum pressure printed on the tyre sidewall. Inspect the tread and sidewalls for uneven wear, cuts, cracks, bulges or other visible damage. A tyre-pressure monitoring system is helpful, but it does not replace monthly checks with a gauge.
2. When should I get help from a tyre professional?
Get a qualified tyre professional to inspect a tyre if you notice visible damage, repeated pressure loss, unusual wear, or anything that concerns you. Do not continue driving on a tyre that appears unsafe. Use a spare only if it is suitable for the vehicle and can be fitted safely; otherwise contact roadside assistance.
3. Can I notice a tyre problem while driving?
Yes. A sudden change such as pressure loss, vibration, unusual noise or the vehicle pulling to one side may indicate a tyre or wheel problem. Reduce speed smoothly, stop in a safe place and arrange a professional inspection. Do not ignore a change in how the vehicle feels or sounds.
4. Which tyre approval markings are accepted in Uganda?
STASSU’s Uganda-specific guidance is that DOT and E4 approvals are accepted in Uganda, including for imported tyres. Importers and consumers should verify the applicable UNBS conformity requirements. Ask a reputable supplier or qualified tyre professional if you are unsure how to read a marking.
5. Which Ugandan standards apply to different tyre categories?
STASSU’s local guidance identifies these applicable compulsory standards by tyre category:
- Truck and bus tyres — US EAS 357:2004
- Light-truck tyres — US EAS 359:2004
- Passenger-car tyres — US EAS 358:2004
- Motorcycle tyres — US ISO 10231:2003
- Truck and bus metric-series tyres — US ISO 4209-2:2012
Ask a reputable tyre supplier or qualified tyre professional which standard and approval marking applies to the tyre you are buying.
6. What is the minimum tyre tread depth?
Under the Traffic and Road Safety (Motor Vehicle Inspection) Regulations, 2016 (S.I. 2016 No. 51), a tyre is a reason for inspection failure if tread depth is less than 1.6 mm in the central three-quarters of the tread pattern. This is the tread-depth threshold listed for vehicle inspection.
7. How can I find when a tyre was manufactured?
When a tyre carries a U.S. Department of Transportation (DOT) Tire Identification Number (TIN), its final four digits on tyres made in 2000 or later show the week and year of manufacture. For example, “2324” means the 23rd week of 2024. If the date code is unclear, ask the seller, manufacturer or a qualified tyre professional to identify the marking on that tyre.
8. What can affect tyre performance?
Tyre performance and condition are affected by age, storage and use. Important factors include inflation pressure, vehicle load, speed, temperature, impacts and road-hazard damage. Regular checks and following the vehicle and tyre manufacturers’ instructions help support safe performance.
9. What professional tyre services might be needed?
A tyre professional can inspect tyres and advise whether rotation, wheel balancing or wheel alignment is needed. Follow the vehicle owner’s manual and the professional’s assessment rather than assuming every service is required at the same interval. After wheel work, ask the technician to tighten the wheel nuts to the vehicle manufacturer’s specified torque.
