Is there a maximum tire diameter the dealer can configure the speedo and odometer for?

I want to run a 33 inch tire can they adjust for that?

Thanks

i think they can do up to 35" or maybe up to 37" if i could remeber!

It depends on the truck year. Prior to 2006 there was more flexibility, I think you could program in about any pinion factor. 2006 and newer the computer/dealer programer will max out with the largest OEM tire option. Something like a smarty can program more sizes.

I believe the Smarty can go up to 44". Mine is set at 37.

Post some pics when you get it done. I always wanted to see a second gen with 19.5's.

I think it's a 285/70.

Thanks for all the help. When I put the 19.5s on my 97 all I needed was $15.00 part.

Thanks again.

I'd post pictures but I don't know how.

the newer ones, 2006/2007 and , I think. . . is 285. . . .gotta buy a smarty if you wish to program for bigger.

Not to hijack the thread, but what is the largest tire you can put on a 2005 4x4 that is stock? I do pull a 27' camper so safety is also a factor
