Good questions
Street-legal FAQs
Do I need the wide flares to be street legal?
In states that require tire coverage, the narrow Crawler flares alone usually won't cover oversized tires. Hook on the Street Series wide flares for road driving, then pull them off for the trail.
Can I drive on the street with only the narrow flares?
The Crawler Series narrow flares are built for trail clearance. If your tires stick out past them, you may be out of spec in states with a coverage rule. Check your state above.
My state isn't listed. What should I do?
Check your state's vehicle code or ask your local inspection station. You can also contact us with your tire size and we'll help you plan the right setup.
