can either use the OE 195/45/16 or the 182's 205/45/16. lots about tyres on here - they came on 195/45/16 Contisports originally, which are still avail for about 60/70ea. few other options in 195/45/16 for similar money. not sure, but think the Toyos may be a bit cheaper, and are a popular tyre anyway
OE tyre on the 182 was the 205/45/16 Michelin PE2, which are silly money in comparison (£90+ea). Hankook V12s are popular in the 205 width and similar money to the 195 Contis (got some one at the moment and they're fine - hoping they'll last longer than the Contis, which don't seem to wear well)
probably just best to stick with a well recognised brand
