Frequently Asked Questions (FAQs)
1. What is the clearance between trailer tire and fender?
When your trailer is fully loaded, there should be a minimum clearance of 3 inches between the top of the tire and the underside of the fender. This ensures sufficient clearance for potholes and bumps.
2. Can I paint plastic trailer fenders?
If the plastic fenders are made of soft, flexible materials like polypropylene or polyethylene, painting may not be possible as the paint won't adhere. However, if the fenders are made of materials like Zytel or ABS, they can be painted. Clean the fenders well, slightly abrade the surface, and use a plastic-specific paint like Krylon Fusion.
3. How do you measure for full fenders?
When measuring for full fenders, the fender should be at least 8mm wider than the tire. It is even better to have a 10-12mm wider fender. For example, if you have 32mm or 1 1/4" tires, get 45mm fenders. If you have 42mm tires, get 50 or 52mm fenders.
4. How high should trailer fenders be above tires?
In most cases, trailer fenders should be mounted at least 4 inches above the tire. This allows for deflection and prevents any road debris from damaging the tire or fender.
5. How much toe in should a trailer axle have?
The toe of a trailer axle should be set at 1/16". This slight toe-in position compensates for steering deflection caused by road friction between the tire and the road when the trailer is in motion.
6. What paint to use for fenders?
For painting fenders, choose a high-quality enamel or polyurethane automotive paint. Make sure the color coat has a flex additive to prevent paint cracking. Clean the outer surface lightly with a high-grade degreaser, avoiding lacquer thinner or enamel reducer as they can repel the paint.
