Where to get gauge adjusted to correct big tires?

My tundras speedometer is off by 3 or 4 mph. I was wondering where I could get this fixed or could it be a DIY project?

 

Do I buy one that's $100 or have someone do it.

 

Ok cool. Thank you

 

I'd rather just adjust it in my head than spend that haha

 

Haha true. I am just going to head to the Toyota dealership today and see what they say.

 

Lol

 

Let us know. If that works, I'll ask them to adjust mine at my 50k mile service, but I'd say they'll want some unjustifiable amount of money for that as well haha

 

I tried to get the dealer calibrate the speedo on my wife’s 4Runner. They said they couldn’t do it. I was willing to pay so I don’t know if they can’t do it or if I need to find a new dealership.

 

Alright just went to the dealership and they said they can’t adjust the speedometer.

 

Now I went to Les Schwab a tire center place and they said you need a programmer or a calibrater. Most shops won’t do it. Bummer
