I had a tractor that had three of the eight studs broke off never had a problem with it. if you lost 2 of 5 that might be different.
you can always pull hub and usually studs can be knocked out with hammer and punch and put in new studs.

Here's a few options I can think of:
Get a longer, slightly undersized bolt, nylon lock nut, and washers and rig it if the backside of the hub is accessible and if you're comfortable with the remaining bolts doing most of the work holding the wheel on the hub.
If you have a tap and die set, try retapping the holes in the hub and cutting fresh threads on the bolts. This can often work if the cross threading only occurred at the start of the threads on the male and female ends.
If you don't have a tap and die set, individual taps aren't too expensive, and retap the hole in the hub and get fresh replacement bolts with good sharp thread on them.
If the threads were buggered up all the way through the hole in the hub, it may be necessary to go up a size by boring the hole with a slightly larger drill bit and tapping it with a new larger tap, and fresh larger bolts.
If it's threaded studs on the hub that are buggered, I think Bruce offered a great approach by knocking the old ones out and pressing a new one in.
Those are the best DIY repairs I can think of at the moment. Hope these ideas are of help! :)

If the threads are not in the hub, the lug bolt will have knurling that is pressed into the hub. If the that interface is compromised at the hub, hole now making it too large for the standard lug bolts knurling, options may be limited. It is possible that another application would have the same length or longer and a slightly larger knurl diameter. But just because we want that doesn't mean that they make that particular stud. A spot weld on the edge of the bolts head to secure it is an option. But it sounds like the threads have been buggered. Sometimes in a pinch a castellated nut put on in reverse can clean the threads of damaged bolts. Using a thread cutting file might be difficult depending on how close the bolt circle is.
