Wheel poke calculation question...

Hi,

My 08 sport wheels have a +30 offset. The Sema 4 runner wheels a +4. That's a pretty simple calculation even for me. That is a 26 mm or 1 inch difference. The 4runner wheel will have an inch more poke than my sport wheel and I've seen that stated before. But do you not have to also take into account that the 4runner wheel is a half inch more narrow? Am I wrong to think then, that the measurement from the center line of the wheel to the face is therefore .25 inch less than that of the measurement of the sport wheel, and that needs to be subtracted from the inch in offset difference? If so the 4runner wheel would only have .75 inch more poke than the sport wheel and not 1 full inch? Thanks for any clarification!

What are the two wheel widths?

 

7 and 7.5

 

Yes. Approximately 3/4”

 

Thanks for the response @gotoman1969

 

Roger that. Glad I could help.

 

@gotoman1969 is correct, rim width plays a roll and in this instance the 4Runner wheels will sit just a touch over 3/4" further outwards.
