Vijay Mallya believes Paul di Resta could struggle to get to grips with the new Pirelli tyres after a dismal debut in Hungary.
Force India left the Budapest race without adding a single World Championship point to their tally as both di Resta and team-mate Adrian Sutil failed to reach the chequered flag.
However, the duo were having problems long before hydraulic leaks put them out of the grand prix as neither driver was able to get any pace out of their new Pirelli tyres.
"The tyres have played an important part in determining performance the whole season," Mallya told Press Association.
"We invested in resources to understand the tyres better and that worked for us very well, which is evident in our position as we are fifth in the Constructors' Championship.
"But after Silverstone the tyres changed. It would be fair to say we are going up a steep learning curve to try and understand these tyres better.
"In the last race in Budapest, Paul in particular struggled with his tyres all weekend. They did absolutely nothing for him. He was unusually uncompetitive.
"And you know Paul's track record. Whenever we as a team have made a mistake and he has had to start from a position he shouldn't have, he has finished in the points, but in Hungary nothing worked for him.
"So Hungary was forgettable as far as I'm concerned, but hopefully we'll get on top of the tyre situation before the next race in Belgium, and come back as strong as we were from then on."
However, Mallya fears that one of his drivers will struggle even more to get on top of the new tyres as he reckons they are not suited to di Resta's driving style.
"Yes, Paul had a problem (in Hungary), but that problem is specific to Paul. It's not a car problem because the same thing would have happened to Adrian as well.
"It's a problem we need to fix for Paul, and we know we can because Adrian was comfortable with the tyres.
"The two have very different driving styles - Adrian is harder on his tyres, Paul is softer, can make them last longer.
"Therefore, maybe it takes a lot longer for him to get heat into the tyres and for them to start functioning. It can be a whole range of things.
"So it would be wrong on my part to admonish the car at this stage."
