Hey John or anyone else that might know, I need some of your expert advice. What air pressure should I run in a 275/35/20 on a 10 inch wide rim?? <---44lbs???? Also I have a 255/35/20 on a 8.5 rim? I think that one should be around 41????
Is this correct?
Thanks Dude/Dudes

I threw out my Tire guide.
38-40. 40 to be safe from our lovely pot holes we have and that tiny little sidewall you are running on.

I figured it from memory. lol
there's more factors involved, one important being are the tires in question SL or XL?
Standard load or extra load?
Manufactures will slightly vary, but heres an example
235/50/18 Hankook Ventus V4ES load capacity of 1609@51psi SL 97W
235/50/18 OE BFG KDWS carries a load capacity of 1609@44psi SL 97W
255/35/20 Hankook Ventus V4ES load capacity of 1609@50psi XL 97W
275/35/20 Ventus V12 Evo K110 load capacity of 1874@50psi XL 102Y 1/3" taller sidewall really matters from your different F/R size.
That being said, roughly the OE tire at 35psi carries (a total guess 1500lbs) What Ford wants
and the 255/35/20 hankook tire at 35 psi carries (a total guess 1300lbs)
So to keep what Ford wants in the tire load, you need more psi........

The tire guide book I had would give you the load rating at different psi's so you could figure out how much 1 psi changed the load capacity. I really need that to give an exact recommendation.

Run the fronts at 39.745183343691733996270975761342 psi exactly
and the rears at 34.148515571941399049189870961473 psi exactly
hope you have a large display digital tire gauge LOL

Delivery time all depends on the driver's route on any given day. Aside from Priority and First overnight packages, we do not guarantee specific delivery times. If you can't have the package left at your door, have the package held at a FedEx Office store for pickup
Its being held at a fedx store. I'll pick it up today.
Happy Birthday Nick!!
What are you half my age? That would be 28 by the way.

Happy birthday Nick.
Finally got my Redline hood struts installed today. Everything went well, but I lost one of the locking clips because I didn't fully seat it, so I can't use them quite yet. The passenger side strut will pop off if the hood is almost closed.
Fedex finally delivered my two packages. I don't know when I'm going to install the CAI and tune though. I'm going to Livernois on Thursday to do some dyno testing with the Ford Racing power pack. Sounds like a before & after dyno, but it should be pretty cool.
