Tyres.co.uk offers Michelin Primacy 5 and Bridgestone Turanza 6 in the size 215/55 R16 93V, which will fit most standard 16-inch E 320 saloons from 1997 to 2002. Be aware that certain factory variants of the wheel are approved to different specifications. You should confirm the registration and look at the fuel filler flap placard.
Information on the 320 can be found on the tyre pressure placard located behind the fuel filler flap. Once you have looked at the placard, ensure you check the specification of the tyre in question as well as the registration as approved fitments can vary with the wheel in question.
You are not obligated to purchase four new tyres for the 320, but you should purchase a pair as a minimum and fit new tyres to the rear (as per UK tyre safety guidelines) on the same axle. If you own the 4MATIC version, all four tyres must have the same specifications and rolling circumference, so a minimum purchase of four is required if a suitable match cannot be sourced.
