Need help on rim size

I recently just purchased a used 06 pre runner and they are 6 lug with tire size 245/75/16. I found some off road rims and tires on Craig's list and they are 6 lug and the seller says it will fit tacoma and 4runner,is there anything I need to know before I purchase these rims?

 

Forgot to post the sellers rim and tire size, the off road rims are 16 rims with 245/75/16 tires, same tires and rim size I currently have.

 

Tacomas have 6 lugs on a 5.5 circle. Should be the same for the majority of 6 lug suvs/trucks. Nothing more I could really tell you unless I knew more about the wheels (manufacturer, materials used)! If you think they look good when you roll it up next to your truck buy em.

Do they come with center caps?

 

I purchased them but no center caps, and don't know what brand the rims are. What can I do to get some center caps? Or am I screwed.

 

Center is 4 3/16 circle

 

You're definitely not screwed but its gonna take some digging to find some. I'd measure again to double check. 4 3/16 is a pretty big number. I've seen 3 3/16 all over the place. Just use the Internet to your advantage. Between eBay, Amazon, and google there's gotta be something out there.

 

Well I have a bigger problem than just the center caps. I just installed the rears and they fit perfect but when I started the front it hits the brake drum. Do you have any suggestions?
