Sauber believe Pirelli have brought the wrong tyres to Texas as they are "too hard" for the circuit.
The drivers had a fight on their hands on Friday keeping their cars pointed in the right direction as many slipped off the track while others spun.
The reason for this was not only the slippery nature of the new track surface but also cooler than expected temperatures which meant it was not easy getting heat into the medium and hard compounds that Pirelli opted to use this weekend.
"The biggest challenge is to get the tyres to work, as they are definitely too hard for the circuit," said Sauber's head of track engineering Giampaolo Dall'Ara.
This was a sentiment echoed up by Kamui Kobayashi, who fears it could ruin his qualifying.
"I must say I have big warm up problems with both compounds," said the Japanese driver.
"It just doesn't work in qualifying if you need ten laps to get the tyres to work. We will now go and look for solutions."
