sorry if this was brought up but i couldnt find anything but if i put 30/9.5/15 on my truck ( my stocks were the 235) i know my speedo is gonna be a little off but will it hurt anything if i dont get it recalibrated?

 

No I don't think it will hurt anything you will just have to figure out how much it is off by to maby keep from getting tickets.

 

alright thanks.

 

use miata tire calculator to from google to figure out your size difference. Honestly when I put 31's on there was only a tiny difference. Like 3mph when going 50. Just depends on the percentage its off. Now MY 33's are 14% off. So when I'm going 50 I'm going 57ish and that was from the stock 235/75 size tires

 

alright thanks alot i put 30/9.5/15 dunlops on my truck with the irocs i finished it looks really good!

 

Pics or it didn't happen!
