hey is anyone running the 51 series procomp rock crawler rims on a sierra, i want to get them for my 86 drover in 15x7 and will be running 30" tyres, but i dont now which ones to get in regards to offset and backspace. the three types listed on the website are:

offset -38mm backspace 2.5"
offset -6mm backspace 3.75"
offset 12mm backspace 4.5"

i dont know much about rim sizes but i think i probably need the second size. any help ?? cheers guys. anton.

They take forever like 6 months they say 6 weeks not true. I have the 15x8 with 2.5 backspacing they are fairly wide. Depends how far out the guards you want them?

6 months geez that sucks, my old man gets em in 2 wks i dont really want them to stick out heaps i will be running extended flares but i just dont want them to rub on the inside.

Got these on my 89 wt with the 3.75 backspacing. They fit fine and with 235s they poke out enough to keep the zuk looking pretty grotty. They dont look too illegal but if I got pulled over by someone in a bad mood they might try pinning me for it. I'd say go for it. Wish I knew they made a bigger offset, when I bought em the told me 3.75 was as far as I could go. Unless they meant that was all they had in stock. Took a few weeks to ship em from memory.

Mine were made on ordering so that adds time. They are pretty much just a cut and flipped rim so you could buy 15x7 and make your own offset. I'd love to go further but can't be bothered and gotta finish my other car
