Clarification on offset for wheels

[BlankMan]

Just want to make sure I understand this correctly.

The positive offset for wheels on the 8g means the rim lip sits out futher than the wheel hub, right? So getting wheels with a smaller offset - say +40 - means the outer lip of the rim, and therefore the sidewall of the tires, will be set further under the fender, right? And getting wheels with a larger offset like +48 will push the tires out more?

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel.

so a wheel with a +46mm offset will stick out like stock. a wheel with a +48mm would stick into the car 2mm than stock. and then a wheel with like a +44mm would stick out of the car 2mm

yeah think of it this way... the more offset (+), the more the rim/tire is tucked towards the center of the car. the less offset, the more the rim/tire sticks out. for instance, those cars that have the skateboard look w/ the tires out past the fender... those are negative offset rims.

our stock offset is +46.

Got it, now. I had it backwards. Thanks for the clarificaiton.

I've shopped high and large, and it is hard as hell to find +46 offset. I do find some in 17/18 inch, but I can't find any in 16''. Also, from further research, it seems that if you have a 7.5'' width wheel with +45 offset and the same wheel gets smaller 6.5'' width it will be +40. I understand the reason for offset, I just am too stupid to figure the science behind it :wink: :idea:

Heh I was wondering about this myself, seems I got it backwards myself. I found rims with +45 offset, good nuff.

[pinoyesv6]

if its small rims don't fret. im running a +38mm offset with 7 inch wide wheels 16 in wheels to be exact. no real problems so far...

[Reelax]

guys... the offset is in millimeters. +46 is the stock value. most rims for front wheel drive cars will come in +38, +40, +45 etc. so together w/ ther rim width, you can figure out if it's gonna fit. the farther from +46 the narrow ther rim will have to b to fit our wheel well. so a +38 with a 8.5" width will stick out much farther than a +45 7.0". i am running 225/40zr18 18x7.5 +45 and have no clearance issues even w/ a 2.5" drop turning the wheel lock to lock w/ no fender roll.

I am thinking to get a wheel for my 8g with this size:

Front: 19 x 7.5 with offset +53 (215/35/19)
Rear: 19 x 9.0 with offset +45 (235 or 245 /35/19)

with all rear's fenders rolled.

Will it be fit into my car???

Thank you for your opinions.

good luck with the 9 inch wheels in the back. i mean by having a low offset u run a risk of rubbing on a fender but with a wider wheel and a higher offset u run into problems with rubbing with the suspension components...

im pretty sure 9" will not fit in the rear... the highest i've seen is 8.5" w/ no camber kit... it would have to b even less if you added the camber kit. also 245 on a 9" +45 rim will rub (the strut will catch it because the wheel does not move straigt up and down and if you fix that w/ a camber kit, you would hit the fenders)... 235 would barely fit and you would have to roll the fenders w/o a camber kit as well but i think your wheels would hit the fender on big bumps.

i realize ur trying to go for the staggered look (useless on a FWD or AWD car) but realize that the front wheels are the drive wheels... you want those to be as wide as will allow. i suggest 225 in the front in any wheel height. also at a 7.5" +53 offset you are in danger of rubbing your front suspension and inner wheel wells when the wheel turns or on big hits. 7.5" +45 in the front is about as perfect as it gets (flush)

your best bet would b 7.5 or 8.0 (even 8.5) at all corners +45 w/ 225/35zr19.

one more thing is remember that if you keep the series the same (in this case 35), the wider you go, the taller the wheel since the series is a ratio of the width... a height of a 225/35zr19 is 35% of 225mm (78.75mm) and 245/35zr19 is 35% of 245mm (85.75mm). of course a 245/30zr19 would b 73.5mm tall... i think only dunlop makes this size right now. for total tire height, double the figure u get from the series x width + rim height (there is tire on top and bottom of the wheel).

So what you guys think the best offset for the front (19x7.5) and rear (19x8.5) with what size of tires for both?

Thank's guys

just try to stay close to the stock +46mm offset. also keep in mind that if u do have wider wheels in the back, ur car will look funny when u rotate ur tires. most plus sized tires are driectional, meaning they can only move front to back and back to front and not side to side like the stock tires. so yea if u still wanna rotate ur tires, u might wanna stay with wheels of the same size
