speed rating question

This isnt taco related but it is tire related, my dd needs new tires and walmart had some on sale, my car takes v speed rated tires from the factory and the tires on sale at walmart were t speed rated. The people at the walmart tire center strongly advised against putting t rated tires on if the car takes a v rated tire.

They tried to get me to buy some other expensive tires and i passed, partially because i overheard the 2 auto center employees arguing because they put the wrong oil in somebody's car, after i hearing that i decided i didnt want them working on my car.

If the t speed rated tires are gonna be ok on my car i'll go back, buy just the tires and get another shop to mount them.

The walmart employees told me if i put a t rated tire on a car that needed v the car will handle like crap and the tires will wear out fast.

 

I forgot to add i searched around the internet and couldnt find a definite answer
