Ive been looking into getting some hub centric spacers. Terra firms sells a 30mm but I'm looking for something a little wider, anybody know a reputable company that makes wider Hub-centric spacers that can take some rough off-road driving?

 

I would be hesitant to use spacers for any, let alone "rough" off-road driving.
There are a LOT of forces happening at the wheels on our very heavy LR3s

Can you just get wider tires on stock wheels? Like 285/60R18?
Or can you explain why you think spacers will help your wheeling?

 

If wider tires will work on the stock 18s I would probably do that instead. I just don't want to buy new wheels as I really like what I have now. An I've heard that adding some width to the wheel base can help steady the car as I have a 2" coil lift setup. I believe the tire I use now is a 265/65R18, However, Im pretty sure 265 is the widest I can go unless I change the wheel

 

Lots run 285/60R18 - but I am not one of them

Search for that size and see what info/pics you find
Maybe someone who has can reply here also

 

Spacers, if not used to properly off-set a wheel for correction only, tend to create a lever with the wheel and put excess pressure on the bearings. They can also become a weak point and they themselves fail. Not a huge issue with light cars, certainly an issue with heavier cars/trucks. Just imagine how a bearing would handle a wheel moved five feet out, just for imagination. Picture that leverage. And 30mm is over an inch, so while it may not seem like a lot the math adds up. Its all a risk thing in the end.

 

275/65/18 is a good size if you want wider without issues of rubbing .
