There are 3 different tires for the Traxxas UDR. those are, KR3, pro-line Racing, and the paddle wheels. The KR3 and the paddle tires are 15.5 inches in length.

Different Tires Sizes and Characteristics
These 3 different tires have some distinguishing characteristics. And each of them has its pros and cons. Below we have discussed all tires in detail.
So let’s begin!
Traxxas 8475 Desert Racer Wheels with Paddle Tires:
The paddle tires are best to use in the sand. These tires are quite big in comparison to the pro-line tires. Also, these tiers are an ounce heavy as well. Traxxas udr fox goes greatly with these tires.
But these tires perform best in the sand because they have a paddle-like grip on them.

And like we use the paddle in the water, these paddle tires can push through the sand as well. The Traxxas UDR aluminum chassis can be a major upgrade with these tires.
These tires are quite grippy as well. The rubber which is used to make these tires are soft and sticky. So it even grasps on loose sand and as well in the snow as well.
The Traxxas UDR chassis can handle these tires. These tires are even compatible with Traxxas UDR custom body. In fact, I would recommend you get a TRAXXAS 1/7 Unlimited Desert Racer frame side protection board.
This will provide you with proper protection from the pebbles and rocks in the dessert.
Pro-Line Racing 1/7 Hyrax All-Terrain Unlimited Desert Racer Tires:
The proline tires are the best in many scenarios. These tires are like paddle tires. But it’s hard to use the paddle tires in other terrains than sandy areas. This can be a serious Traxxas udr upgrades.

These tires have a lot of groves and cuts in them. So these tires can perform on the normal flat roads, muddy areas, and even in desserts as well. You can also use these tires whether you’re using a ⅛ or 1/10 scale RC.
The tires are a bit lighter and smaller in comparison to the other 2 tires. The length is 2 inches, which is less than the other two tires. Also, the weight is an ounce lighter than two of the tires.
Tire KR3 Traxxas 85076-4:
Thee KR3 tires are a bit basic in comparison to the other two tires. Because these tires don’t have anything special to offer. These are kind of like the pro-line tires, but a bit less capable.
Although, you cannot see these with the Traxxas udr 8s. You can also see these tires coming with the Traxxas udr kit.

These tires can be used on sandy terrains. Also, they have some similarities with the paddle tires. Other than the paddle grips, the length, width, height, and weight are the same. These tires are often seen with Traxxas udr roller.
Also, these tires need to have foam inside them. These tires can perform in a lot of terrains. So, these are UDR compatible.
Gluing the tires to the wheels is really important. Without proper gluing of the tires, the tires can slide right off.
