Original size tires on 1987 Civic Si?
Can anyone tell me what the original size tires were from the factory
on the 1987 Civic Si? If someone is good at math, can you tell me what the speed difference would be, as indicated on the speedometer, between this stock size and the currently installed P185-65-R15 at, say, 60mph? Also, where can one obtain the driven gear (or whatever it is called) that would correct the speedometer for the above current tire size? Thanks a bunch. |
Re: Original size tires on 1987 Civic Si?
I have the Honda service manual for the 1987 Civic (US model) and it
confirms what the previous poster said. 175/70R13 82T to be precise.

Re: Original size tires on 1987 Civic Si?
I believe the tire sizes given below are for the non-SI versions. I
just went outside and looked at my '87 SI - the tires are 185/60R14s and I haven't changed sizes. My manual is in the garage, but again, the the non-SIs have 13 inch tires, the SI has 14 inch.

Re: Original size tires on 1987 Civic Si?
The service manual specifies 175/70 R 13 82T for the 1500 Si hatch back.
175/70 R 13 for the 1500 DX hatchback and 165/70 R 13 for the base 1300 hatch. This is also what is listed on the web site of Goodyear for that car. Are you sure your car has the original tire size?

Re: Original size tires on 1987 Civic Si?
Hmm, this gets interesting. I'm the only owner of this car. Just
took a look at the data label on the driver's side door and 2 sizes are listed: The first is the 175/70 R13 and the second is the 185/60 R14. Took a look at tirerack.com and it said 185/60 R14. Wondering now if the 14 inch was an option, not standard?

Re: Original size tires on 1987 Civic Si?
Dunno. I've never personally owned a Civic Si. I double checked
tirerack.com again and I did the search under "Shop for Tires," selected "Honda" and "1987." Then selected "Civic Si Hatchback" which stated the OE was 175/70-13 for this car. However when I searched the CRX Si, it listed the 185/60-14 as you stated. The plot thickens! Haven't seen a reply from the OP (Tina) yet, but what does the sticker on the door indicate? Either way, go with the previously stated sizing method. It works.
