Since it appears you already have the 614's mounted, and as already stated may have rims that are not sufficient for the higher pressure, it appears you need to do some investigating. The first thing is to find out what you do have in terms of the rims. Tredit.com is the website where they show the rims that are supplied and the weight ratings for the respective rims. See what you have and see if they are rated for 3200 pounds or 3750 pounds. If they are rated for 3200 pounds, then my understanding is you are limited to 80 psi which on your 614's would provide 3042 pounds per tire. You may also want to contact Tredit directly for confirmation. This is barely sufficient considering your loaded rig weight appears to be 13,715. Your pin weight will be the deciding factor as to whether this weight capacity is sufficient for your rig. It may be a better alternative to see if Tredit or another supplier can give you a deal on some 110 psi rated rims and go ahead and bite the bullet and make the swap. You do have some research to do before you can decide what pressure you can safely use.
