I have 06 super cab 4x4 xlt 5.4 .Just put in 2.5 leveling kit running 265/70r 18 tires looking to go a little bigger. Think these are around 32.4 tall what would be a good size without changing rim size? would like to go around 34

 

go with a 285/75 which is a 33. if you go 34 or 35 depending on the tire you take a chance of it running. i had 315/70 on my truck with just a leveling kit. it rubbed slightly, but a little trimming and it was fine.

 

315/70 what type and brand looks like i have enough rom with out rubbing I going to look at both thanks

 

i have the bfg a/ts. here are a few pics of them on my truck with my leveling kit. this should give you a pretty good idea of flex and what not.
