i have a 91 chevy and it has a 5 lug pattern and the rims want only come in a 6 lug what would be the safest cheapest and easiest way to get around this..  

You could either do adapters, if any are made for 5-to-6 lug, or use 4x4 spindles, which are 6-lug. Sorry I can't be of more help. Anyone else have any ideas?  

Have you tried emailing the company that makes them and make sure that is the only way they come?  

Yeah, actually a lot of the time they'll custom-drill the lug pattern for you. But if they're popped out of a factory in China (you'd be surprised by how many are) chances are, they won't do custom lug patterns.  

I have a 00 GMC Sierra it has a 6 bolt pattern. Maybe someone could shine a bit of light on this for me. I Too have found a set of 20's and a Set of 22's.

The thing that has me a bit concerned even though there are many trucks out there that have large rims under them.

Is there any wear and tear on the bolts that hold the rim to the Rotors? Would/Should you have to get stronger bolts or higher rated bolts? I believe that bolts used for vehicles are rated #8. Would you need to beef that up to a #10 or would they be alright as they are?

   I dont know if this will help you out but I have a case on point for ya. Had a customer come in the shop in 1997 he had a shortbed extended cab GMC he wanted to convert it into a dually just to have a shortbed, one of a kind dually. I bolted adapters onto his exsising front and rear wheel studs (Used Loctite just on the studs holding the adapters to the truck) then bolted up Bud aluminum custom dually wheels to it. He still is drivin it today never had any problems and he has 2 tires on the rear.
I think a bunch of the success or failure comes from your driving habits and routine maintainance.It is a good idead to check your lug nut torque at least once evey 3 weeks especially on custom rims. I do on all my hotrods.  

If you're really concerned, do Stage 8 bolts. Honestly, the bigger concern for me is braking power. A lot of guys bolt up 22s and 24s but don't do anything to their brakes. If I knew I was going to keep the big rims on permanently, the very next thing I'd do is put bigger brakes on.  

You won't have any probably with the wheel studs. I personally am against wheel adapters. When bolting alum to steel the bolts will always back out. So like any alum wheel you should keep them torque but with adapters you have the wheels and adapters to back out on you...but if you do run adapters do like Escatruk said use lock tight and re torque often!!     And yeah big wheels = big brakes….That’s always a good idea.
