typical aftermaket rim centterbore? is 4x100mm rim compatible with 4 on 4" lugs

[northguest47]

time to get new rims for the aveo - so its 38mm offset, 56.6mm centerbore, 4x100 for the stock steelies i believe. i really like the 14" kosei k1 ts for its low weight and currently want to go with them but it appears they are 5 lug bolt pattern, so something similar i guess. now heres the funny part bear with me - i want to match the rims on my car to the ones on the aluminum trailer i am building and the half axles have a hub thats 4 on 4" with a 62.74mm centerbore so two questions arise for me 1) is 4x100mm the same/compatible with 4 on 4"? I called five shops and couldn't get a straight answer - now if you do the math 4 on 4" is actually 101.6mm, 1.6mm longer on the diameter so thats .8mm on the lugs which i assume could be within tolerance but i'm looking for corroboration on this forum from someone who perhaps has worked with trailer hubs. 2) are most aftermarket rims with a larger centerbore than 62.74? lastly, since trailer wheels are usually zero offset, i'm looking at using 1 1/2" 4x100 wheel spacers which i need to make sure will fit on the 4 x 4" hub (they wouldn't put in longer studs i asked). the half axles arrive in a week or so so i can start test fitting then.. just looking to the forum for input/constructive criticism
