    Does anyone know if a 15"x8" 8-lug wheel with 2.75" back spacing will fit on a 8-lug 10 bolt without having to grind on the backing plate and caliper? Thanks.

    No, they won't. They will take less grinding then a rim with more BS will but you will still have to grind. Keep in mind the less BS your rims are the harder it will be on your balljoints. If you plan to wheel hard with rims at 2.75" BS then make sure you know how to change balljoints because those rims will put a workout on your ball joints.

    It should work fine. I'm running 15x10 with 2.5" BS and zero grinding and it still has a little bit of room. You might have to grind a tiny bit on the caliper but not the backing plate.

    5trucks: I'll be selling mine in about a month when I switch over to 16.5s

    i have 15x10 with 2.75" backspacing and did not have to grind anything.

    also on the balljoint thing, i have run 3 years with these wheels on new cheap balljoints. they show no slop. i used to DD it up almost a year ago and wheel fairly often. ive been told (by people on this site) they would bearly last me a year.

    I'm more worried about wheel bearings than ball joints.

    They all have a lifetime warranty, though. :waytogo:

    A friend of mine put these exact same spec wheels (15x8 w/ 2.75" BS) on a Ford D60 with dual piston calipers and they fit with zero grinding, so I would have to think they would fit on an 8-lug 10-bolt.

    As far as the comments regarding balljoint wear.........they only stickout maybe an inch more versus a "regular" wheel. Heck, a 15x8 with 2.75" BS sticks out less then a 15x10 with a normal 4"-ish BS.

    I know 2 guys first hand that have D44's with 2.75" wheels. They wheel often and have had to replace balljoints every 4-6 months during the wheeling season. These are Moog balljoints not the cheapo junkers either. I hope you won't have to but it is a concern to be aware of.

    I've got 15x10 8lug 2.75" BS on my 44" boggers. theres just a touch of clearancing on the GM D60 caliper. I have total confidence they'd slam onto a 10 bolt no problem.
