I found some rims that are 6 bolt. The guy said the size on the rims said 15 x jj77. I don't have a clue what the jj77 means and I can not figure it out? I looked it up on the net and nothing? Someone told me that chevy's had same bolt pattern? is this true?

 

its just a manufacturing code.... chevy 6 lug and toyta 6 lug patterns are the same... both 6 on 5.5"

the rim is a 15x7

 

There may be a mixup in the dimensions, likely it is 15x7JJ:

The JJ would designate the wheel contour.

While it is true that Chevy wheels have the same bolt pattern (6 on 5.5"), you need to be careful with the ID of the hole in the wheel center, make sure its large enough to fit over your front hubs. Some Chevy wheels have smaller holes that will not fit. Also measure the backspacing to make sure it is proper for your application.

 

Cool, thanks for the info. Does anyone know which years of Chevy will fit our truck? This guy said that they were off a 80's chevy truck. Or should I just bring my spare and measure wheel for wheel?

 

there is no real what years chevy truck will fit... due to a bunch of differnt factors... do a search around here... there is something about the center bore needs to be a certain amount of mm wide to clear the toyota hubs... i dont remember the # off hand....

 

Yes, just measure the ID of the center hole of your spare rim and the Chevy one. The issue is Chevy 4x4s have a smaller diameter locking hub that Toyota uses. So some Chevy wheels have small center holes, others are larger.
