quick wheel question (or two)

Recommended Posts

hey guys 

right now i have 295/75-16s on the bronco (it an 87 i only use as a plow truck) 

 

i got a lead on a set of BFG A/Ts in 33/10.5-15s on steel rims 

(with them being over an inch narrower, im sure they will plow much better then the slicks i have on there now)

the guys said he had bought them for a 74 Jeep CJ, so the bolt pattern should be 5X5.5 , just like the bronco 

the wheels look like aftermarket wheels, so im sure they are the biggest centerbore possible, but just for the record, what centerbore do i need?

 

and can i use the same lugnuts on the steels wheels as i have been using on the aluminums? 

 

anything else to consider ? (im still waiting to hear back on the backspacing)

Yo diy,

or measure the hole in your spare. I personally would trust my own numbers.

I lost all my back spacing info when my German Host comoany took my annual fee and ran.

Thanks, I'm pretty sure the rims I have now are 4 inches of backspace, the centerbore on my spare seems to be 3.5 inches 

 

I'm sure the wheels I'm looking at are aftermarket ones, so the centerbore I expect to be quite large 

 

Can I use the same lug nuts as I have for my aluminum wheels?

Yo diy,

I don't know. Stop by a mom and pop tire store and ask.  I will look in my 96 Owners Manual, will post if I find anything relevant.

Exactly this^^^. 
All the factory wheels used the 1/2-20 tapered nuts prolly for the last billion years or so."
But the new wheels need to looked at by a tire/wheel shop for the lug nut type.

thanks mieks 

 

i picked the wheels up this morning and everything went on smoothly 

the lugnuts i have i bought a while ago 

they have the proper taper on them, and are solid, not the ridiculous capped ones ford used 

it turns out the aluminum rims i had werent stock to begin with, and they have a larger center bore then my spare, but it is the same a the steelies i bought, so the centercaps swapped over 

 

i torqued them  to 85 foot pounds, sound about right?

Yo,

"Evenly tighten 1/2-20 lug nuts to 74-133 lb-ft

NOTE: Torque specifications are for clean, dirt- and paint-free, dry bolt and nut threads. Never use oil or grease on studs or nuts."
