Trailer tire clearance

cford36 · Jul 7, 2014

I have a 7500# trailer. The concern I have is that I have noticed that it does not seem that there is room for full travel before the tires will rub the fenders. I just replaced the tires, same size but upgraded from C range to D. The tires do extended slightly outside the fenders. When fully loaded I cannot put my finger between the tire and fender, so when going over something they appear to rub the fender.

What should be the normal clearance? I am considering moving the fenders up higher for more clearance. I will post pictures when I get some.

What size tires are on it now? A 7500# trailer should have 205/75/15 or 14's. A 225 is usually too big and causes the issue you are having.

They are 205/75/15, same as the the ones I took off. Only difference is the load range, which I don't think should make a difference in size.

These are the old tires but it looked the same unloaded.

It looks like your axles are several inches too wide for your trailer frame.

Yours look like the same amount of clearance and bow legged as mine. I think your axles will hit the frame before you hit the fenders.

Here is a pic of mine loaded down and they never rub.

I have on one trailer taken an adjustable wrench and radiused the fender lip where there may be contact with the sidewall. If you do small bends at a time it looks pretty good.
