Need Some Advice.

Hey guys sorry for not being much on here but I have a few questions. I plan on doing a sled pull one of these days and need some advice for my first run. I have an automatic.

:umno:
1. Will my stock hitch be ok ?
2. I have 37x12.50 PJ's are these tires ok for this and can handle it?
3. How should I prepare for my first pull?
4. 4Hi or 4low start in 2 gear or 1st.
:thankyou2:

Thanks for the help guys let me know what ya'll think.

Pj's out to hook very well i would clap your leaf springs and run 4 low second gear and manually shift into 3rd if u have the power to pull 3rd
