i have an old set of giovanna wheels i wanna sell on ebay, but i forgot what the offset was. inside the rims it says 18x8.5 and thats all the information i could find. i sent an email to giovanna with the pics of the wheels to find some information on it but they never email back.

is there a way to measure the offset of the wheel?

thank you.

 

anyone?

Yes but I’m not certain that it can be done with precision. See: http://www.tirerack.com/wheels/tech/...jsp?techid=101

 

yay. thx very much guys.

using the chart 002 provided, i found the offset to be about 32mm. that is close enough.

now off to ebay!!

thx again guys. what would i be without you ppl.

 

Positive or negative?

 

You'll find the offset stamped into the back of one of the spokes..

ET XX will be how its shown.

 

yeah... should be stamped on the back as Chris said!

 

What's the purpose of knowing the offset of the wheels? I still don't understand it. Somebody please help answer my dumb question.

 

Fairlady, the offset locates the rim in or out (pos or neg), which combined with your tire size could end up with a tire that doesn't fit in the space available. People use diff offsets to get their favorite rim and tire combo as close to the fender lip as they can without cutting the tires... If you go to eBay and buy 19x8.5 rims, you still could end up with a setup that won't fit under the fender. You need to know the offset.

 

Thanks for the explanation. slaponte

 

ok guys. i took some pics of everything i see behind the wheel. check em out and see if you can tell the offset please. sorry about the bad pics. my camera sucks ***.

it looks like "2" to my eyes.


what does JJ stand for??


im wondering if this is 3/8 or 38??


hehe. the old school. this was on my old camry. believe it or not, this design was pretty hot back then.

 

+38 offset

JJ is the safety rating... It is rated for passenger vehicles... Passenger vehicles being passenger car...

Truck wheels have different ratings...

that depends on weight...

I have a chart at work for that...

Now taht I think of it... JJ is rated for small truck / highway use & passenger vehicle...

J is highperformance alloy...

ehh.. ill look at the chart

 

ahhhhhhhhhhhhhhhhh. thank you very much!!

damn. my calculation was off by 6mm.

i always thought it was saying 3/8 with that line in the middle.

i hope i can sell these on ebay.

thank you guys and wish me luck~

 

Also thoes wheels are 18x8 not 18x8.5

 

The wheels I'm having on my car doesn't state any offset anywhere on the back of the rim.

 

yes. i just saw that couple of days ago. somehow i always thought these wheels were 8.5
