FAQs
What do the numbers 245/40 R20 mean?
245 is the tire width in millimeters, 40 is the aspect ratio (sidewall height as a percentage of width), and R20 indicates it is a radial tire for a 20-inch wheel.
What does the XL marking stand for?
XL stands for Extra Load, meaning the tire is reinforced to carry a higher load capacity than a standard load tire of the same size.
Can I use these tires in snow?
The Street-H MU71 is a performance-oriented tire. While it handles standard road conditions well, it is not a dedicated winter or snow tire and may lack grip in deep snow or icy conditions.
How often should I replace these tires?
Tires should be replaced when the tread depth reaches the manufacturer's minimum safety depth, typically 2/32 of an inch, or if the rubber shows signs of dry rot or physical damage.
Does this tire come with a tread-life warranty?
Warranties vary based on the region and the retailer. Please refer to your specific purchase documentation or the Dynamo tire website for regional warranty details.
Troubleshooting
Uneven tread wear
Check wheel alignment and ensure tire pressure is set to the manufacturer's specification.
Vibration at high speeds
The tire may require re-balancing; consult a professional technician to inspect the balance and potential road hazard damage.
Tire loses pressure frequently
Inspect for small punctures, check the valve stem for leaks, or have the bead seating inspected by a tire shop.

Maintenance Tips:

- Periodic Rotation: Rotate tires every 5,000 to 7,000 miles to promote balanced wear across the set.
- Visual Inspections: Regularly check the sidewalls and tread for signs of punctures, uneven wear, or debris lodged in the grooves.
- Wheel Alignment: Have your vehicle's alignment checked annually or if you notice the vehicle pulling to one side.
