Wheel space question

Hi

I have just been offered a smokin deal on a set of 18 aftermarket rims and tires but the hub cut out on the new rims is too small for my 07 tacoma crew 4x4. If I order wheel spacers it will push the wheel out too far and look odd ... any suggestions to make these rims work .... besides machining the new rim hub cutout .... ???? the aftermarket rims are lug centric (cone) drilled as well.

So the wheels in question are hub-centric for a Chevy, right? That would be the combo that would work on our trucks, save for the 78mm hub bore they have. Just because they have conical seat lug holes does not mean they are lug centric. 99% of aftermarket wheels are conical seat.

A machine shop can further bore the hub bore out for you. I've seen it done several times on here.

thks ... I will call the local machine shop and see what it will cost .... by chance does anyone have the specific diameter and depth of the hub housing on my 07 Tacoma .... I would like to know the exact info. Also the tires are a 285/65r18 .... if I machine the rim to fit (rim offset is just over 5 inches) do you think I will have rub issues?

Tacoma hubs are 106mm.

The wheels have over 5 inches of backspacing year mean? That's cutting it really close for UCA rubbing. How wide are the wheels?

The definition of lug centric: wheels that have a conical lug seat.

It does not matter if the hub is precise, too large, or off center... conical lug pockets forces the wheel to center to the lugs and is the definition of lug centric.

I've never heard of that definition before. So you would say that if a wheel has conical seat lugs, and a precise hub ring or bore, that it is both hub centric and lug-centric at the same time?

Wheels that are not hubcentric are known as lugcentric, as the job of centering is done by the lug nuts assuming they are properly torqued down.
Centerbore on aftermarket wheels must be equal to or greater than that of the hub, otherwise the wheel cannot be mounted on the car. Many aftermarket wheels come with "hubcentric rings" that lock or slide into the back of the wheel to adapt a wheel with a larger centerbore to a smaller hub.[3]

The definition of hub centric is a wheel which uses a precise hub bore as its method of centering. The only way it can do that is if the lugs cannot force the wheel to center (factory style flat base lugs) due to allowable play. If the hub were as tight a seat as the lug seats on a lug centric wheel the wheel could not be slid on by hand due to excessively tight clearance issues.

My factory wheels (Gulf States Toyota wheels), and my current wheels (BBS's from an 04 tundra limited) are hub-centric, factory wheels, and both have conical seat lug nuts from the factory. Not all hub centric wheels have shank and washer style. The clearance issue you are talking about would only occur if the hub and studs were machined out-of-spec.

I think and easier way to think of it is that if a the weight of a wheel is supported by the hub, it must be centered by that hub, so it's hub centric. If the weight of the wheel is supported by the lugs, it's lug centric.

Here is another example of a hub-centric wheel that uses 60 degree conical seat lugs.

Here are a couple more hub centric v lug centric comparisions:

The wheel is therefore lug-centric, as the wheel is centered by the lugs rather than by the hub. There are some people who will say that driving on lug-centric wheels doesn't really matter as long as the lugnuts are the self-centering cone type, as they will adequately center the wheel. These people are wrong. Driving on lug-centric wheels means that any impact will apply shear force to the lug studs, forces at 90 degrees to those the studs are designed to handle.

A: Hub centric wheels are manufactured so that when they
are installed on a vehicle, the wheels are located directly
off of the center flange of the brake drum or rotor.
This is done to insure that the outer beads of the wheel are
concentric with the wheel bearings. The result is a much
truer, better balanced tire/wheel assembly. This is very
important with modern hightech suspension systems.


Q: What about the phrase “Lug Centric”?
Isn’t it just as good?

A: NO! Lug centric is a marketing phrase made up by the few
manufacturers who don't offer hub centric wheels.
Their theory is that if the wheels are drilled for conical seat
lug nuts, then the wheels will self locate.
Surveys have shown that most installers just hang the
wheel/tire combination on the studs and put on the lug
nuts expecting the angle of the conical seat to pull the
wheel/tire combination into concentricity.
Recent tests by several major wheel manufacturers have
shown that when the above mentioned mis-locating
occurs the studs actually bend down slightly thus creating
an artificial out-of-round condition by as much as .0025

based on the fact that the hub bore is to small??
You can't get those no matter what because they won't fit on your hubs to begin with. Those are for a chevy (78 mm hub bore)

I talked with spidertrax and they don't make a spacer with a hub centric reducer .. which would be a cool thing ... but .... no luck

http://www.spidertrax.com/Toyota-Hub...&category=9982


If I machine them, (per one of the reply posts) I am concerned with the rub issue .... I could machine them AND put spacers in but I am thinkin it will too costly and I may end up with fender rub .... think I will pass on these wheels and tires ...

Just for mention ... yes the aftermarket rims are a chev bore but they also come drilled as a conical lug mount as well ... Spidertrax makes a Tacoma spacer for that would work if I purchased conical lug nuts .... but I am concerned at the appearance with a 1.25" plus spacer as they are a big wheel and tire .... I think will go with a set of 17 tires on my stock rims and bump the series to a bit bigger tire ...

thks for everyones help on this
