Here are some tire sizes that might be used on a BMW 2002, listed in order of outside diameter:
(1) from Diameter stock
BMW 2002 Tire Size IndexTire size index for Classic BMW Model 2002
|195/55-14||22.4||-1.3||3, 4, 5|
|165R-13||22.7||0.0||Stock'02 size (except 2002 Turbo)|
|195/60-14||23.2||+2.2||Stock size for some E30 (3,8)|
|185/70-13||23.2||+2.2||Stock size for 2002 Turbo|
|195/65-14||24.0||+5.7||Stock size for some E30 (3, 4, 5, 6, 8 )|
- Diameter is approximate. It varies with tire manufacturer and model. It also decreases about 1.1 % from new tread (10/32 inch) to no tread (2/32 inch).
- Differential ratio is effectively reduced by this amount, e.g. with 195/65-14 tires the stock 3.64:1 ratio becomes 3.44:1. Speedometer reading is reduced by this amount, e.g. with 195/65-14 tires the speedo
reads 61.5 at 65 MPH. Speedo reading increases as tires wear (1). Speedo reading varies with normal manufacturing tolerances, typically -2/+5 % IMO.
- Slight, occasional rubbing on front inner fender walls at full lock is common with these sizes.
- Slight, occasional rubbing on tie rod boots possible on tii.
- Slight, occasional rubbing on front fender lips is common.
- Slight, occasional rubbing on front apron is possible.
- Rolling, trimming, or stretching of fender lips is required for clearance.
- E30 (’84-’91 3-series) 14-inch alloy wheels fit ’02s well and are a common upgrade. If tires are included, try for 195/60 rather than 195/65. Replace steel wheel nuts with alloy wheel nuts.
- E21 320i wheels fit ’02s poorly because of their different offset.
Comments and corrections are encouraged.
