Importance of matching OEM Center Bore on new wheels?
Hi guys, I'll try to keep this as short as I can.
I've just recently picked up a set of Cragar "Soft 8" Steel wheels in a 16x8 size, with the correct 8x6.5 bolt pattern to fit on my '95 Ford E250-based Sportsmobile. (RB30 layout, 2WD, 5.8L). I'm planning on mounting a slightly-up-sized (but still factory OEM optional size for E250) set of 245/75/16 Cooper Discoverer AT3's on them.
Is it absolutely critical for an aftermarket set of steel wheels to have the same, identical center-bore opening as the OEM (factory original) wheels had on them? (Such that the wheel will be truly, properly hub-centric)?
I'm sure these aftermarket wheels are made to fit Ford, GM, and Dodge considerations, which I know all have different center bores.....but I thought Ford had the largest bore (which I believe is 4.88" for 1995), and yet these wheels come with an even-larger 5.150" center bore. This over-sized center-bore opening would make these wheels be lug-centric when I mount them.
For the weight of these rigs, should I be concerned about that? I've read elsewhere several opinions that for steel wheels, it's not a problem. (And that for almost all aftermarket wheels, which are made to fit a lot of different considerations, they almost always err on the side of making the center bore extra-large.)
Hub-centric? Lug-centric? Does it matter for these rigs/wheels?
Again, thanks you guys!!!
