How fast am I going?

[Stroked95]

My speedo says 55, I have 4.10 gears and a 34.6 inch tall tire. Also how far off will this skew the odometer reading?
There was a site that had a calculator for this but I don't remember it. I don't think it said anything about distance traveled either. Thanks for any help

Speedo recalibration

Here is an article to recalibrate your speedo for your tire size, it's real easy

If I remember right, the stock tires are a shade over 33 inches. So, unless you swapped those gears in you should be fairly close to accurate.

Edit: 235/85-16's are just under 32. You shouldn't be too far off anyhow.

I always thought that it was 31 inches

the tire size varied though out the years mine came with 32s my buddy had one with 31 i think it could depend on the dealer too. anyway i had 3.73 with stock tires and switched over to 4.10s with roughly 35s and the speedo seems pretty accurate
