Title: Offset question (warning contains an image)
Post by: Jeeper Creeper on April 13, 2009, 04:39:52 PM

I'm thinking about buying them but have that nagging feeling they might be wrong offset. All those chrome wheels I see on the net seem to be quite a deep dish and those don't look so deep. Can you guys tell from that pic if they are going to be OK for my TJ? It's too far for me to just go have a look at them and the seller don't seem to know much about them.

Thanks

EDIT: If I do go to buy them how can I tell what offset they are?

If they came off a Jeep, then they'll be fine on yours.

normally to measure the offset its a simple case of putting a straight edge on across the inside edge of the rim and the measure to the bolitng face of the wheel.

what are the size of the tyres ?

if they are 33x12's then they would most likely be on a 4" offset which puts the wheels further out in the wheel well, the other option would be at least 3" but should fit anyway

Concur with Dave....But 3.75 is also an option.

Just out of interest, do deeper dish wheels stick out more? I was checking on eBay but most don't mention off-set or back-spacing, made me wonder if they are all the same...

I don’t know if this helps:

Looks like the less back-spacing the more they stick out.

Thanks

Those look similar to mine .... American racing 767s I think... They will either be 8" width rim or 10" width rim and will be 3.75 to 4" offset and will  both fit a 12.50 x33 or 35.
You will be fully covered by a 7" arch and almost covered by a 6" arch.

I was told they are Rock Crawler with 33x12.5x15 Kumhos.
