Distance and Mounting

• Most states share a common formula for mud flap placement. Although the mathematics seem esoteric, they're simply intended to keep water and debris from slipping from under the tire and hitting the car behind at an angle greater than 22.5 degrees. In inches, measure the distance from the tire's rearmost point of contact (with the trailer fully loaded) with the road to where you'd like to mount the mud flap, and multiply it by 0.4142. Take that measurement, and measure upward from the ground at your desired mounting point; this is your maximum allowable mud flap ground clearance. Example: if you wish to mount the mud flap 18 inches from the rearmost contact point of the rear tire, multiply 18 by 0.4142; this gives you a maximum of 7.45 inches from the ground. A simpler calculation often used by roadside officials to determine angle is 5 inches of vertical rise for every 12 inches horizontal from the contact patch.
  
  

Ground Clearance

• Regardless of the mudflap's distance from the wheel center, one nearly universal rule is that it can never be more than ten inches from the ground. Many states (like Texas) have height restrictions under ten inches (usually eight inches while driving), but ten is the maximum allowable. Using the 0.414 rule of angle, maximum distance from the tire's rear contact patch will rarely ever be more than 24.14 inches.

) Does my vehicle need mud flaps/mud guards?

Answer: Non commercial vehicles (under 8,000 lbs.) need fenders or mud guards (mud flaps) within 27 inches of the pavement behind all wheels. Commercial vehicles need fenders or mudguards (mud flaps) within 10 inches behind all wheels. (ORS 815.180)

Mark

 

I got inspected yesterday just east of Yuma on I-8..DPS pick up came out of no-where. Officer was cool, liked the fact I didn't stop a hazmat load on the freeway and went down the Dateland ramp, found a wide spot and let him do his thing. Level 1, no problems. He was very knowledgeable about the electronic logs too. Handed him my keyboard, he checked 7 days back without any "hunting and pecking". Split in 15 minutes.
