gear ratio for new rims and tires

[citus23]

I drive an '08 F250 King Ranch 4x4 with stock 20" rims and 33 inch tall tires. I drive around the country for my job and tow a 27' toy hauler. I want to upgrade my rims to a 22" Foose rim and my tires to a 35" tall Nitto Terra Grappler. I also want to put a "Ready Lift" 2.5" lift. My question is is there a perfered gear ratio i should go with? I am not sure what my stock ratio is at this time. I have several other upgrades I want to do as well including a Firestone "ride rite" system, but I will ask those questions in another forum

Thanks for the help

You have 373 gears now (stock). 35s would NOT make a tremendous difference, but you may notice it a little sluggish when towing. If you do want to change gears, I would go with 410s or 430s.

I'm running a 325-60-20 toyo on stock rim...its 35.5 tall...I put in 4.10 tows like stock even at GVW...if you drive around the country with the mud grapplers be prepared to listen to your stereo loud
