help with offset.

hey guys,

can anyone tell me what offset i will need on a 15x7 set of wheels,
if i want it sitting the same as a 15x8 +25 set of wheels.

im not quite sure on how to work this out exactly. any help is appreciated.

sorry my wording isnt the best. feel free to correct me haha

thanks guys

anyway, 15x8+25 will poke 4x25.4-25mm= 76.6mm from the hub mounting surface

You'd need that 76.6mm from hub for the 17x7 to have the same poke

You'll need 76.6mm-3.5*25.4" = roughly 10mm

thanks for they website man. but im a little lost with the info. so with 7 inch width, i need to go 15x7 +10??

thanks for the help man.

pretty much.

look for +10

By sitting the same, you mean the same amount of "poke"?

The rim will stick out the same amount as a 15x8 +25 with a 15x7 +12/+13

The wheel is an inch wider, so add half an inch to each side (12.7mm). Isn't it that simple? Neglecting the degree of tyre stretch and just talking about the rim itself.

Charliebrown, I always know i can count on you

thanks for that fellas! just wanted to know exctly how i can calculate it for future
reference.

cheers
