Royals' bosses want to expand after a strong first season in the Premiership.
But Wokingham Borough Council has raised formal objections to increasing the stadium capacity from 24,000 up to 38,000 seats.
Wokingham planners claim match day parking causes misery on roads across the district and would get worse.
