Wheel Help Needed: Offset for 16x8"? Center bore?

[OldSkoolFool]

Hi all. I have been researching rim options for the Wedges and have a couple questions. I love the TVR OZ split 15x8" rims but do not love the limited and pricey tire options (225/50/15 right?). My plan would be to get a 16x8" rim instead and run a 225/45/16 (23.97" diameter) tire which is almost the same diameter as the 225/50/15 (23.86" diameter). The 225/45/16 has some more tire options and is more reasonably priced too.

After much rim shopping, I find myself being incredibly interested in many of ESM's (http://www.esmwheels.com/ California, USA) rims as they would compliment the Wedges very nicely. Right now, they have a 40% off deal through the 29th of this month on the rim I am most interested in which is the ESM-009R (http://esmwheels.com/index.php?route=product/product&path=59_64_85_110&product_id=125).

What I have been unable to find is the offset of the TVR OZ rims. 350i rims I thought were 23. Are the 15x8" OZ's the same? The ESM 009R 16x8" 5x112 rim has the option of 20 or 30 it looks like for offset so please advise, which would be the offset to go with? Also, what size center bore is needed?

Thanks!

Thanks for the info gents. This helps. Not 100% which model of V8 Wedge yet but will be either 350i, 390SE, 350SE, or 400SE.

Excuse my lack of wheel knowledge but does the center bore really matter as long as it is large enough to fit over the hub? So let's say the hub is 63.5, if the rim has a bore of say 66, the lug nuts will not center the rim on a V8 Wedge? Or is it more just that it is nice to have an exact bore size so it is easier to mount the rim, but not necessarily necessary?

All, thanks for the continuation of info. So again excuse my ignorance, but there are at least SOME vehicles where the center bore does not matter and the lugs DO center the rim correct? I have done my fair share of rim mounting/dismounting and feel like most vehicles are like this. The Wedge is just not one of those vehicles?

Is the center bore 63.5 on all 350i, 390SE, 350SE, 400SE? This might sound kind of silly but I might be purchasing rims before officially purchasing V8 Wedge.

For the 245's at the rear, what sidewall aspect were you using or would recommend? What offset then if say 15, 20, and 30 are the only choices? I would most likely just do 8" wide and 225's all around to keep things simple but I am open to options.

Any opinions on the ESM rims? Other suggestions for 16" rims that match the "era" of the car? I need a polished lip and either five spoke or lattice/BBS kind of spoked design.


Thanks!

Well, I chatted with the rim folks and they said having a proper center bore is necessary. So now I am not confident which way to go on this regarding some of the comments here and also with experience on some older cars (ex: Datsun 240Z) where the rim does not rest on the hub so it seemed like the center bore did not matter.

Either way, I am planning on ordering a set of rims and want to make sure I get the proper center bore machined. So, is 63.4 what I need for a center bore and that will work for the various V8 Wedges I am considering (350i, 350SE, 390SE, 400SE)? If 63.4 is not what I need, please enlighten me to what it is!

Thanks!
