I can not directly comment on the shim kit .
I will tell ypu that my E450 was like driving on ice until
I lowered the tire pressures. The RV dealer said to use 10% above the
80lbs rating on the tires.
They were way off. My local independent trucking center conferment that to me.
I have learned to read the tire pressure tables and found more information.
Using Michelin's chart:
225/75/16E
65 PSI Single (Front) equates to the GAWR of the 4600# front axle E450 used through 2007 (chassis year)
and
75PSI works out to GAWR of the 5000# axle used from 2008 up.
65 PSI should be your front tires max pressure.
The back could be up to 80 psi depending on load.
Duel = axle lbs
70 PSI for Duels = 4440 lbs
75 PSI for Duels = 4660 lbs
80 PSI for Duels = 4940 lbs
Hope this helps.
I have found that local independent commercial truck shops understand
the E650-450 more than other shops that work on mainly cars and P/U trucks.
