Wheel Size's

[Avenged]

Good Eve!

I was wondering,
if i put, say the 19" Snowflake alloy's on my car, would the size of the wheel's
give me a falsespeed reading on the dash?

i have them on mine and i dont notice the diffrence

Im not sure to be honest but, as they are a factory fit wheel I would imagine that they should be OK.

I have them on mine and the speed is fairly accurate although it is out a slight bit with the sat nav at speed, I think most speedos are though??

Im sure someone will know on here and comment soon enough.

The majority of Vectra C are calibrated for 215/55R16 (all those imported from Russelsheim are)
So long as they are 235/35R19, then the difference is negligible

This is so true, But i have found that in a safe & controlled environment That when having my criuse set at 85 mph, the gps actually came out @ 82 mph
This was on standard 215/55R16 alloys.
