speedometer off?

[Hondafreak333]

So my speedometer is off and im not sure where to start. Its all stock on 31x10.5 15's. When the speedo shows im doing exactly 30 my actual speed is 35 and when it says im doing 60 I'm actually doing 70. Thoughts?

You are undergeared. You need a lower ratio to have it be correct. It's not a big deal, just remember that you are going faster than it says.

yep, that's about right. its because you're running larger than stock tires.

My 33s are only off by like 5 mph at 60.

Thats odd because my mom's 95 4runner has the 31's and is all stock and her speedo is right on?

Not every truck came with 31s from the factory.

My speedo is off by 20 mph with 31's. Supposed to have 225's on it and it was off 15 with those. I'm thinking someone messed with my cluster before I got it or my cluster is junk. Don't know how to tell whether it's mechanical or electrical.

I just use my GPS for speed since both my rigs are off. I'm running 33's & 4:88 on both.
