For those that dont understand backspacing and offset

s_dimenickel · 03-11-2008, 06:30 PM

ok im still confused by all this shit

i have a set of wheels that are 18x7
backspacing im told is +42mm which figures out to be 1.65 inches
bolt pattern is 5x110

im having an adapter made, what size adapter will i need to still keep the wheels behind the fenders.

Would a 20x8.5 with +25mm offset work on an s10/blazer?

hac327 · 03-22-2008, 10:17 PM

ok well i am just like anyone else who has posted asking if this fits and here it goes...

i got a set of ADR 18"s front are 8.5" wide with 15 offset,...the rears are 9.5 wide with the same 15 offset....

i did a dry fit and cam up with some interesting measurments,

the fronts will rub a little cause i had the truck in the air and did a full left to right test, i am sure i will rub a little on the sway bar and upper a arm if i turn the wheel just about to its max.....

the rear dry fit leaves the rim about 3/4" away from the leafspring. and i am going to have to relocate the ebrake line a little, depending on what information i can gather from a couple of posts.

should i space them out 5/16? or more? now i dont want them to stick out past the fender wells though either i need to find a happy medium i guess....

thoughts?

hac327 · 03-28-2008, 12:25 AM

so with my rear being 9.5 wide i have 6.5" backspacing?

and my fronts being 8.5 wide i have 6" backapacing?

hac327 · 03-28-2008, 01:33 AM

edit to my last post,...

rears are indefinetly 18/9.5 with 6" backspacing
fronts are 18/8.5 with 5 1/4" back spacing

and i am looking for the tires that will not stick out past the over all width of the rim past 1/2" please

dekeyser · 04-03-2008, 12:19 PM

I dont want the rims to stick out past the fender...but i dont want them tucked in either.... any help is appreciated....thanks

ugacowboy55 · 04-07-2008, 09:46 PM

i have a stock 2001 s10 i am replacing my wheels with 15x7 with a 4.5 bs i know the bolt patterns are correct and everything so i know that checks out. i plan on having 225/75/r15 toyo open countrys on the new wheels. will all of this have proper clearance and minimal rto no rub?

TwizTid · 06-08-2008, 03:57 PM

im a little confused on this backspace/offset. Im looking to get some 18 inch wheels with these specs:
18x8.5" with a 5x4.75 bolt pattern +18mm offset and 5.5" backspacing

I have a 5/6 drop on my truck and id be using 245/40/18 tires. Would this setup be ok? Any help would be appreciated . thanks

slammed3drsdime · 06-09-2008, 01:57 PM

i am gonna order the kmc novas 20x8.5 0mm offset 4.75 backspacing what problems will i have and will they work fine i have no inners and im bout to tub the front

kickflipking_04 · 07-23-2008, 08:51 PM

So when the chart on the first page says:
7" --- 0 - 4mm
8" --- 4 - 10mm
8.5" --- 5 - 15mm

Does that mean for example on the rims that are 8inchs wide +4 throw +10 ??

im hiding tire now and these are the same height

thanks jim

RuLayd · 08-16-2008, 12:01 AM

whats the deal with fwd offset?
The specs are 22" rims-
Fitment: 5lug FWD offset (5x120/5x114.3+35m)

would these work for my first gen? Turning problems? Will they stick out, do i need spacers?

DISCLAIMER: (3.5" lip on 22x7.5/22X8 and 6"+ lip on 22x9.5 and 24x10)

Thank you!

yz85608 · 08-21-2008, 12:39 PM

So a 19X12with a offset of 59mm would have a bs of 8.11"
which would require a 2.61" spacer?
