I thought about automotive tires, but everyone claims you can't use them. I know they are of different construction, but what are the cons to using auto tires?

One of the cons that I am aware of is that the auto tires have more sidewall flex. So with a tandem axle setup...the tires are put to the extreme when parking the HTT.
Another cons is the construction of the sidewall on the auto tires. The trailer tires are made to withstand the elements longer (sun, rain, etc.).
I am sure there are more...so maybe someone else will chime in.

A 205/75R14 passenger car tire is only rated at 1532 pounds or 6132 pounds for a set of four.
An ST205/75R14 trailer tire is rated at 1760 pounds or 7040 pounds for a set of four. You lose nearly 1000 pounds of tire capacity with car tires.

I talked with a tire guy who sells mostly automotive tires. He strongly warned against using automobile tires on a trailer. What is the real reason for not using them... providing that they have enough plies, can handle the same weights, and speed rating, what can go wrong?
Enquiring minds want to know. 
NOTE;
I posted this and saw the last 2 replies after it refreshed.

Has anyone run these? http://www.walmart.com/catalog/product.d........=&tire_equivalent_load_index=&tire_size=
Seems to meet the requirements. Says its a ST at the top, but it says it is a LT tire in the specs. See this link... http://www.walmart.com/catalog/tires_res........&tire_width=175&vehicle_path=false&year=

Has anyone uses 185's in place of 175's? There is only a .7" difference in height, & .2" wider.
They are rated for an additional 120 lbs. of capacity.

No reason not to other than they're almost impossible to find.

Last fall we searched & searched for American made replacement tires. Ended up with Greenball tires from Discount Tire. So far very pleased.......they are the best we could find (Maxxis were #2 choice). Unfortunately, they are not American made. Wanted Michelins but they did not make our size (same as OP.)
Best of luck!
