Toad vehicle tires wearing uneven

We flat tow a 2013 Ford Edge behind our Allegro Bus. Our new car now sounds like it has flat spots. A very noisey ride. When it came time to rotate our car tires they said it was wearing uneven because it is towed behind a bus. .....Can anyone shed some light on this.

Make sure that the tow bar arms extend and lock equal length. If the alignment and toe-in is correct on the car, and the steering wheel is unlocked so the front wheels are free to track, I don't know why your tires would be wearing excessively.

I see two possible issues.

One.. The tow bar baseplate may have been improperly installed.. For example 2 inches to one side.

Second, alignment, it may need nothing more than re-alignment, and make sure the alignment tech knows you tow it.

Finally.. Tow bar height may be an issue. If I towed that car with most tow bars, and did not use a "Drop hitch" adapter.. Very strange things could be expected due to the difference in the height of the motor home and car ends of the bar (+/- 3" is acceptable per my manual).

I agree with this. You will probably find the problem is in the baseplate.

What an unexpected nightmare. Is the only solution to our flat spots to buy brand new tires? I relied wholly on the Ford mechanic to install my Roadmaster Hitch properly on my new Ford, never thought to check his work when complete. LESSON LEARNED.

Are you unlocking the steering wheel?

FWIW, Our toad will wear the front tires unevenly and they do get noisy after a few thousand miles of towing. DON'T make the mistake of rotating your fronts to the back thinking that will allow them to wear smooth again. In my case all I got for doing that was 4 noisy tires! I've decided to just replace only the fronts more frequently when they get worn badly enough.

I believe some cars are more susceptible to tire wear than others. Several friends tow CRVs and theirs wear unevenly too. I hope you can find an "adjustment" can be made to fix yours. Ed

I'm thinking that different brands and tread patterns of tires may be more susceptible too. An aggressive All Season tread would have the tendency to wear faster in the tow situation than a summer tread with a more solid outer edge.

When I said alignment, I meant to add caster angle. Caster is what allows the wheels be self centered following the track of the RV. It also aids in handling of the car. Bad caster angle is what causes shopping cart wheels to wobble.

Sure wish I had known about tire wear on a car that is towed behind a bus. Should have checked the RV forum for more advice before purchasing a new vehicle. I would have kept my older vehicle had I known. Thanks folks for your opinions.
