35" Tire question

bellpilot · Oct 16, 2013

Hello:
I just purchased a 2013 PW - very happy...
Question: If one adds 35" tires, do you have to re-program the speedometer like a Jeep (using a Procal Module)? Or - am I good to go without any programming?

you can figure out what speeds your actually going and live with it. but fuel mileage etc will be off.

Someone will chome in on if you can reprogram with or without using a tuner. i have no experience doing this, i just learned to live with it.

Hey there bud. I had the same question when I lifted my old Tacoma and I found a website that can help calculate the new speeds for you in relation to the size increase. You have to go per mile, but I just input the primary ones around me and went with that. The link is below:

According to my GPS,my speedometer is still reading the correct speed with 35" tires. I didn't need to recalibrate anything.
