OVtune help?

Hey TW,
I am having a local guy install OVtune on my truck soon. I believe he is going to run the tune for 33" tires.
This may be a stupid question....
I currently have some 16" pizza cutters on there for winter. Smaller tires. Soon I will switch back to my 17" method rims with 275/70/17 ko2's. I think this is about 32 3/4". Almost a 33"
Will it do any harm or what have you to run that tune on my smaller tires for a month?
Cheers

 

Subbed. in the same boat. Just waiting on my 265s to wear down before i throw on 33s

 

It won't hurt anything.

 

I am in the same situation, although I haven't had the OV Tune applied yet because of this question: From what I gathered about the answer is that you can configure the OV Tune for stock size (31's), and later on without re-tuning, replace the tires with 33's without any issues? I plan on changing from the stock 265/70-16's, to 255/85-16 tires in the next few months, but was going to hold off on until I had knew what and if there were going to be any issues, as I didn't want to re-tune again (I am having someone install the OV Tune software, along with the TSB update for me).

 

you're good, enjoy your breakfast.
