Do you know what the ride match system/road force is?I love DTD. The certificates for replacement are the roadside hazard. Damage one and it's replaced for free. Install kit is most likely lug nuts. And valve stems are of course new valve stems. Shipping is where you save with them most of the time at the expense of having to pay for damage replacement.
The install kits are the lugs and hubrings for the wheels. The certificates is the tire replacement warranty (basically like road hazard just better) but yes the charges are necessary. IMO it's a better deal than tire rack.Are people satisfied with DTD? I usually purchase my wheels off of Tire Rack because of protected tired damage etc...
The problem is Tire Rack doesn't sell Konig, so kind of forced to go elsewhere.
Do they still offer road hazard protection?
What are all these charges and are they necessary??? Lol

They make sure the tire and wheel is perfectly matched so there isn't any vibes at all or anything. "Improves longevity and performance" according to them. Most likely snake oil, but I guess it isn't a bad precautionary.
It's basically a sophisticated way of balancing a tire that takes into account variations in the stiffness of the carcass as it rotates and interacts with the road (road force). Some tire makers in the past have used this as part of the manufacturing process, and you would see portions of the tread with grind marks on them. I view this as compensating for quality control variation. Maybe should not be necessary if quality control is good to start with.
The road force is an extra step in the install process which requires a balancer that tells us where the tire needs to mounted on the rim to give you the smoothest possible ride. It measures that lateral runout of the tire and high spot in the wheel. With those factors if they were on top of each other could look like an egg (for lack of better terms). Overall any premium tire should be road forced to get the best possible performance out of the entire unit as a whole. No tire/wheel is made perfectly round. And this extra step helps insure the best possible outcome.
