AO 0235+164 is a well-studied BL Lac throughout allelectromagnetic wavebands. In the present work, we show its optical R-band photometric observations carried out during the period from 2006 November to 2012 December using the Ap6E CCD camera attached to the primary focus of the 70 cm meniscus telescope at Abastumani Observatory, Georgia. During our monitoring period, it showed a large variation of DR = 4.88 mag (14.19- 19.07 mag) and a short timescale of DT- 73.5 minutes. During the period of 2006 December to 2009 November, we made radio observations of the source using the 25 m radio telescope at Xinjiang Astronomical Observatory. By adopting adiscrete correlation function to the optical and radio observations we found that the optical variation leads a?radio variation of 23 2 12.9 days.
