Quality + common sense = wheels spacers stay on
Ching Chong spacers + stupidity = wheel fall off truck breaks

 

This guy knows!

 

I'm running 1.5" spacers on 35x12.5 Federals. I made sure to buy hub centric, aluminum spacers that say they have grade 8 hardware (verified from the stamps when I received them). They were on eBay for like $200 for the set of 4 or something like that. I had to buy them after buying my tires, nobody in town knew of a set of rims that would let them clear with the rubbing I was experiencing. Firestone told me to pick up a set of wheel spacers so I made sure I got good quality spacers. They've made it through jumping curbs (not at speed), hitting bumps fast to give a bit of an airborne feeling, hard cornering, I hit a small median at around 20 while turning and broke a CV axle (couldn't see it and it was in a weird spot in an empty parking lot), and have played around off road with them. No issues. Spacers push the wheel out and cause the same effect on the hubs as a wheel with negative offset would. Just make sure you buy quality and make sure everything is torques appropriately and you should be fine.

 

I don't see these being anymore scary than a set of spokes. I had a car that I put a set of 20" 180 count spokes on. They can with the wheel adaptor that fit over the lugs and the rim slid onto the adaptor. The "center cap" is what held them on. I torqued them at all needed intervals and ran them for 4 years. Never a problem.


I'd think the same would be said for the spacers.
