[brendan_h]

my current rims are from the outside of the rim (faces in toward the diffs) to the edge of my rims are 4.5inch. can somone tell me what this is in degress. im getting new rims and want to get about half an inch more width so what offset do i need?

thanks

You want -25 offset. Measured some of mine this morning, 8" rim was 225mm total width, wheel mating face/surface (WMF or WMS) to inside of the rim is 97 odd mm therefore offset is approx -15.

225mm total width therefore zero offset would be 112mm

Hi,

I have done no calculations for you, but if it's a 15x8 et-25 that you are after, then have a look here:

thanks. so -25offset will get me 5inch offset?

-25mm will give you -25mm offset, or 3" 'backspacing'. (so yes, 5" from the mounting surface to the outside of the rim, and 3" to the inside)

-25 is about the max you can buy off the shelf,other then that you can get custom made or modified to pretty much almost -100mm or more. Mind you, you will run into bearing problems after a reduced period of time.

pro comp make one of the most offset rims you can get off the shelf

-89mm

What are they worth?

[weaves]

king wheels make a - 28 offset which is what i have

[ofr57]

I'm not sure not the general public price .... I'll find out
EDIT: I think thats the wrong one ... but the actual size is fairly significant

[crackatinny]

i just bort some 15x7 sunnies, -6 offset.
with the 31's, it scrubs slightly at full lock. i will need some wheel spacers for it.
but they were cheap

[brendan_h]

i can get -23 offset on some 15x8 that any good or would 25 be better?

[just cruizin']

could you honestly pick 2mm by eye, I won't be too concerned about trying to chase down 25's

Hey, I've got 15x8's with -28 offset and the 32's still rub on the springs so you'll still need to extend the steering stops anyway with most off the shelf wheels, unless you go custom or I think Rockcrawler make rims with big offset but they are pretty expensive.
