Can someone explain how do you calibrate the speedo for different tire sizes in HPT 3.6?
Thank you

Different as in front to rear?
Or just different tire size from factory.
I do not believe there is any way to set a front tire size and a rear tire size seperate. When GM did factory rim size differences, the front and rear tire had tire sizes that came with the small window of like 1-3% difference so the ABS didn't freak out and cause it to engage all the time.
If you are just needing to change the tire size like normal you'd just go under the gear tire wizard in the edit tab. If that didn't work you could manual input the revs/miles stuff under the speedo tab to get your speedo corrected.

Hi and thanks for the reply.
It is to change the rear tire size. And I did change trans and diff in my c5 corvette to one out of a c6 but the diff gear ratio is the same 3:42 as what was in it, just the trans gearing is different.
I don't have my laptop with me so I'm trying to remember but in HPT 3.6 under speedo it says the "gear ratio" 3:42 which is correct
and it doesn't ask for the tire size or diameter but instead it asked I think revolutions per mile, I think that is what it said.
Have you seen that?
Thank you,

Use the gear tire wizard in the edit tab, the tire size can be found there.

Just used the gear tire wizard, it worked like a charm! I switched from 4.10 to 3.42s.... All you have to know is your tire diameter and final drive ratio.
