which 4wheeler has a hub to fit car wheel bolt pattern
none that i'm aware of, but wheel adaptors are relatively cheap, and also relatively easy to make if one isn't available for your particular application.
Get the tape measure or a tire shop multi template and check out the ATV bolt pattern. Some of the Honda ATVs use a 4 bolt, about 4 inch circle that matchs the small Honda car wheels from Civics. The about 5 inch circle Subaru 4 bolt wheel will fit on some older Kawasakis. 5bolt wheels? the 4x4 units seem to match the Ford F150 or early Jeep, Dodge 5.5 inch circle wheel pattern- understandable as it is a old industry standard from Willys days. A couple small 2 wheel drive ATVs with small hub 5 bolts similat to Toyota and small GM- chrome custom car wheels for the Toyota were put on the ATVs as cheap fancy work and fit. The 4 bolt, 4 inch circle is a standard hub from the prewar Austin days- Nissan used them for there licensed production and it is common enough. A 4 1/4 circle?- Early Chrysler compacts used that size, might find a few of the wheel is salvage yard yet. 5 bolt 4.5 inch circle is standard Ford and some Dodge pattern. 3 bolt hub? Rare in US but was a French standard on small Peugot and Renaults, have seen a couple of ATVs- maybe Bombadier production?- that had them, makes sense for cost reasons as 3 bolts is about minimum for reasonable strength and don't have to drill extra hole, insert stud. Some of the ATVs used on streets as 'Implement of Husbandry' get the car wheels put on them when they are used for weed spraying and paint wagon pulling, snow plowing-- local Yamaha dealer has some crossreferences charts in his shop, tire shop also had a couple this wheel fits this offroad vehicle lists. .
