Suggestion: if your going for the Ricksons you might as well order them NOW as they won't charge your for them until they are built and ready to ship.
Heather is a nice informative lady but is remote to the Rickson MFG site.
A few extra words about the setup I have -
- Be prepared for "sticker shock", commercial truck tires cost 2-2.5x what LT tires cost
- I ended up purchasing a 150PSI air compressor for home so I could reliably air up these huge tires. (I run 70psi in front, 90psi in rear) Most places that provide air don't provide enough pressure.
- Lastly, the Toyo M608z's are not quiet and "sing" while on the highway. (noticeably louder than the stock tires they replaced)
