This is a buyer-beware post. If you don't care about customer support or warranty support, then don't both reading, but if you do feel this is important, then buyer beware.
I purchased a set of rims for my SUV. I went to my local shop and had a fitment done and found I need to get rings for my rotors so I would not have vibration once they were installed. My shop installed the rims and immediately, I noticed the front vibrating at about 55 mph and above and could feel it severely in the steering wheel. I was concerned and brought it back to my shop. They rebalanced my tires and the issue persisted. My personal mechanic said that the vibration was indicative of the wheels, so that is why I had my other shop rebalance the tires. I had another shop rebalance and the issue persisted. We began the troubleshooting and the original shop moved the front tires to the back - crossing them and the backs to the front. The vibration moved from the steering wheel to the front seats. My guys said that this was definitely a rim issue. The tires were original factory tires and did not have a vibration on the original rims. I proceeded to have an alignment done and the results of alignment were negligible. My guys checked and rechecked my car and all parties said it was the rims. I provided all possible info to Custom Offsets -pics and shop reports...and Custom Offsets wants more. I've spent more than $200 to do rebalancing, alignments, etc. They do not support the customer, nor do they fight for their customers in such a ridiculous instance that should be a no-brainer to fix.
Do not be fooled - they will tell you they are just the middleman, but you are the customer and they should be supporting you not the manufacturer.
Emma - while we understand your frustration, there is more context to what may have been the issue then relayed. Whether it was a balance issue with the wheels or tires, both would be indicative of a warranty related defect, and in a situation like that, we're obligated to work with the manufacturer of the product in question. That in turn means that what the manufacturer asks for in order to submit a warranty claim, we need to provide to them in order to get you replacement product. From what you're referencing, it is more likely there was a manufacturer related issue with the tires and not the wheels, however, if you still need assistance on getting this resolved, please reach back out to our customer service team and we'll help as we can.
