Hey guys, I purchased a set of CCW 505A's (amazing quality and very happy with the rims)and had them mounted and balanced at a local shop, The wheels balanced but they required alot of weight and the car vibrates like crazy when up around 65-70. I need to get these rebalanced and would like to have the wheels and tires match balanced (tires moved to different locations on the rim to get the best balance- just in case you use a different term than me) does anyone know of a good shop in the New York City area that could handle this??
Definitely sounds like they didn't balance the wheels properly. Maybe they didn't pay attention to the wheel size or something similar. Anyway I don't know of any shops in NYC, but I do suggest that you find a shop that has a Hunter GSP9700 balancing machine. If you go here you can do a search. Good luck. By the way I've used Stafford tire in Clifton, NJ a couple of times with great results, but it's a little bit out of your way.
Had a similar issue with the chrome Z06 replicas I had put on my Z. Sounds wierd, but they removed the tire and turned it 90 degrees before remounting. Still didn't do it, so they went another 90 degrees. Balanced and then had no problems.
I have heard this before but what makes the Hunter GSP9700 balancing machine so special?
This balancing machine puts a roller drum against the tire when it's spinning. This simulates the load that the tire would experience when mounted on the car.

It can compensate for a tire that has excessive lateral or radial runout, or uneven tread wear. Basically junk tires. Any tire that "needs" a Road Force balance, probably shouldn't be on a Corvette. A simple dynamic balance works fine.
all tires have a heavy spot and all wheels do as well .... the GSP9700 w load force variations testing can identify the haevy area of the tire and wheel ... when those two spots are place 180 degrees away from each other the required weight is much less.
Tire and wheel manufacturers continually develop new manufacturing methods to enhance the uniformity of their products because radial runout, lateral runout, force variation and imbalance can affect a vehicle's ride quality.
Match mounting tires on wheels is a process where a tire's installed position on the wheel is specifically selected to help minimize the final combination's force variation and/or imbalance. One match mounting procedure aligns the tire's measured high point of radial force variation with the measured low point of the wheel's radial runout. The other simply aligns the tire's lightest spot with the wheel's heaviest spot.
Original Equipment (OE) tire suppliers are required to mark the tire's "high point" while OE wheel manufacturers mark the wheel's "low point." This helps the vehicle manufacturer match mount combinations that maximize new car ride quality while reducing the amount of balancing weight.
Today, many vehicle manufacturers require the use of a temporary tag applied to tires and wheels that are removed before the vehicle is put into service. Unfortunately this means that there are no permanent marks to reference later.
There was a time when the valve stem hole on standard wheels indicated the optimum place to which the tire should be match mounted. However, with the advent of styled, steel wheels and aluminum alloy wheels, the stem position evolved into an aesthetic issue rather than being a uniformity indicator. Add to this the probability of wheels retaining their original runout after thousands of miles of use and you can understand that simply mounting the tire so the colored dot is at the valve stem is no longer required practice.
We have found that the only way to accurately match mount replacement tires on used original or new aftermarket wheels is to use Hunter tire balancers which have the ability to measure wheel runout and tire force variations under load before the tire and wheel are installed on the vehicle. Using these machines, a colored dot might be positioned anywhere on the wheel relative to each wheel's runout measurement. In the end, the markers have little, if any, relevance when replacement tires are installed.
I have some new 3 piece IForged wheels and I'm having a problem with the back wheels vibrating. I was told to go have them balanced with one of these machines.

You wouldn't still have the Tinnerman nuts on the lug stubs, would you?
I imagine yours are probably long gone, but some of the C6 guys have had problems when putting aftermarket wheels on the new cars. The OE wheels have a countersunk area where these flat washer/nuts will fit into, but many aftermarket wheels don't, and the wheel doesn't mount true to the hub and can create a bad vibe.
The Tinnermans are put on just to hold the rotors on while the car goes down the assembly line. If they're still there, cut 'em off and see if that does any good.

You and me both brother. Had mine done today and it made a world of difference.
I still had problems and I called Vince at iForged and he told me to just ship the wheels and tires to him and he would fix it.
I have a problem with a rim or tire but I can't find anyone around here that realy knows what the problem it.
