Speedo WAY off!

[sector6]

based on what you said, you should be travelling slower than the posted speed limit if referencing your spedo. Worried about getting pulled over for driving too slow?

no, it's not that I'm worried about going too slow. I can't trust what speedo says. I try and do what "seems like" (say 45mph) but I just never know for sure. Just waiting for one of these dick eaters to fuck with me. :D

EDIT: Diggin' your e30 M3, very nice looking!

Thanks for the replys...
Without running out to check, I'm pretty sure they are 195/60/14. I'll double check after I get out of work.

Edit: would running 195/60's vs 65's really make it read that far off though?

You said stock tire size, but early E30s actually have a smaller diameter tire. so what size are you running?

changing the transmission and diff wouldn't make a difference either since all BMW speedos use the same toothed wheel sensor.

Well GPS isn't the most accurate method of checking your speedometer.


What is your actual tire size? A lot of shops will put 195/60/14s on cars and thats incorrect. 195/65/14 is. 205/60/14 is slightly undersized, but only a little.

Hi guys, Hope someone might have some insight into this problem...
My car, 89' 325is all original motor/tranny/rear end/ stock wheels and stock tire size.
Problem: Speedo is reading 12mph faster than I am actually traveling. I calibrated it with my buddies GPS. When I'm going 50mph, the speedo reads roughly 62mph???

This is a major kick in the dick as the cops around here are BALL BUSTERS!! If everything is original spec how can it be so far out of wack? Only a matter of time before I get popped by the PO-PO!!

Not sure what to do on this one...
Any ideas?

Thanks!!
