Light colored ring on tire sidewall

I now have just shy of one thousand miles on 4 new BF Goodrich Comercial T/A tires on my fiver rv. I have not done anything to these tires other than keeping them inflated to a cold pressure of 80psi and covering them when not in use. I have not washed them, driven in rain, applied any dressings, or otherwise.

Today, after returning home from the 3rd trip with these new tires, I was putting on the tire covers and noticed a discoloration ring in the sidewall close to the rim on only on one tire (right side of rv, front axle) and I have not curbed or scuffed them on anything. Plus, it is between the widest part of the tire and the rim so I'm sure it's not a scuff. I know this occured on the 120 mile return trip as I always keep a close watch on my tires - especailly since these are new.

I'm concerned about this since it is only on one tire and the tires are so new. I tow the rv at 70mph on interstate highways, FL heat, and it is not overloaded at all.

Of course, I will contact a local dealer but in the meantime does anyone have any ideas on what this could be.


Editorial Comment:  You're wise to have this inspected by a dealer you know and trust. From a photo only it's difficult to make an accurate diagnosis.

In spite of what you've said, I'm inclined to suspect that this ring may have been produced by something rubbing against the tire. I've seen a car where a plastic guard piece on the wheel well was damaged and rubbed against the sidewall until it was worn down too but leaving a distinct impression on the tire sidewall.

In your case, it might have been a branch or some other object that somehow became lodged in a position that caused it to rub against the sidewall and later fell or was broken off.

When you have your dealer look at it, you may want to see if there is a similar marking on the interior side wall in about the same position. If you see this, it would be vital to unmount the tire and see if there is any evidence of internal tire damage.

Let us know what the dealer concludes.
