I'm planning to get 2" wheel spacers for my 15" rims on my 91 TLC 80,a friend told me that I need to get the hub centric spacers only as the one on the pictures can't stand the weight of the cars as all the weight will be on the bolts and it will get broken if It had a strong hit
Actually, toyota hubs can be considered hub centric or lug centric. it really doesnt f-ing matter. either wheel will work, its the nut that matters.
Also why the f are you adding 2"spacers? do you just want to come back and bitch about them later?
Whether you like spacers or not, the importing thing is to make sure the lug nuts are probably torqued on both the spacer and the wheel. Locktite is also a good idea on the nuts used on the spacer.
Then why not get properly back-spaced wheels? Spacers change the fulcrum of the lever arm that is the wheel. Yes, an offset wheel does the same, but it does it with only ONE connection point instead of two.
Just introducing another failure point into the system.
^while I agree with that in concept, in practice, spacers are highly unlikely to fail if you install them correctly and keep an eye on them. I had a set of spacers hold up to a 45mph rollover (truck flipped almost all the way over in the air before contacting the ground on the opposite side, slider and tires first). Wheels stayed on, spacers were visibly unharmed and I went ahead and re-used them on the replacement rig

The reason is cost. Buying a new set of wheels with more (or less) offset is quite a bit more than a set of spacers. Quality spacers of reasonable size (1.5" or less is my personal limit) can be used with good success by keeping them properly torqued.
Of course, a wheel with the desired offset would be preferred, but for someone that already has wheels and doesn't want to replace them, spacers are an option.
Not every wheel comes in custom backspace. We use cheap $90 steel 17 inch wheels and they only come in one backspace. The rocks destroy them fast and it would be too expensive to order custom backspace wheels for replacements.
