Pirelli will trial a new 18-inch tyre at next week's in-season test at Silverstone.
There has been talk of Formula 1 changing from the current 13-inch tyres to 18-inchers in time for the 2017 season.
Pirelli will be testing the rubber on Day Two at Silverstone with Lotus putting the tyres through their paces.
However, motorsport director Paul Hembery insists the test does not mean F1 will swap tyre sizes in the future.
"The 13-inch tyre is no longer relevant to the everyday road user because even an 18-inch tyre is used by standard vehicles these days," he said.
"While 18-inch tyres would be a big step for Formula One, there are many other motorsport series that already use this size, so there's scope to go even bigger than that in Formula One in years to come.
"In order to underline F1's role as a test bed for future mobility solutions, we believe it benefits everybody to have as close a link between road-car tyres and competition tyres as possible.
"That is a belief we have held ever since we introduced the low- profile tyre from competition to road use back in the 1970s.
"However, we'd like to emphasise this move is not something we are actively pushing for, as our role in Formula One is not to instigate changes.
"Instead, it's to help teams and drivers make the most out of the equipment, regulations and resources they have at their disposal, whatever they decide that framework is going to be."
