Test drive: Poltern/Holpern give off the gas

Hi, yesterday I had a test drive of about 1h at a Kia dealer. The car was a Kia Ceed GT-Line (160ps) with automatic circuit. In itself the car was very promising, only one point I noticed, where I would like to have your assessment. This is the first car with automatic and this PS number I drove, accordingly I wanted to test the following. If I gave strong gas from the stand, came from the front wheels. “Holpern”, as if something were going through (not freaking out, but right punches). After the test drive, of course, I asked the dealer. We drove again together a few times out of line and he said that this would be normal, respectively, that these are probably the wheels that are going crazy. Unfortunately, I couldn’t record a video with the sound, otherwise I would have made it available to you. Unfortunately, I don’t really have much experience with different cars, but the previous ones I drove, just squeaked and didn’t hit so hard when I was spinning the tire. Is this normal? Normally I shouldn’t give so much gas, of course, that the tires are going crazy at all, but even if I did, I would assume that the tires will be damaged at most. But this sounded rather like the vehicle could be damaged directly.
