One of the best upgrades for any offroad vehicle is oversized offroad tires. They offer more traction and more ground clearance. The only issue is that until now, the Sprinter only allowed you to install a max tire size of 33" (275/70/17). Now, thanks for the tire ROM from Owl and Renntech, you can install up to a 35" tire without issue.
Why is the Mercedes ECU tuning software needed?
The Mercedes onboard computer (ECU) checks both the wheel speed and the GPS speed the van is traveling.
By installing a tire larger than a 275, your wheels will turn slower for a given speed (lower wheel RPM) which will therefore cause the computer to think there is a problem. The ECU will then disable Adaptive Cruise Control and Emergency Brake Assist.
The good news is that Renntech and Owl finally have a fix. By plugging in the Renntech Tire ROM to the OBD2 port on your van it will change the acceptable tire size inside the van's ECU allowing all systems to function as intended. You can then remove the ROM and you're done.

Canceled Orders
We want all customers to be happy with their purchases but in the event of a canceled order, we cannot recoup the fees charged to us by the credit card companies. When an order is placed, the credit card company takes a percentage of the sale, typically 5%-6% This is money that DOES NOT go to us and we do not get this charge given back to us when we refund an order. Therefore, if someone buys a suspension and then cancels, we pay the credit card company several hundreds of dollars that we cannot get back. Although you may not have noticed, it is industry standard for larger dollar items to have a "restocking fee" of 15% or more. We do our best to charge exactly what we get charged by the credit card company when you cancel an order. In the event of a canceled order, the 5%-6% that the credit card company charges us cannot be refunded. Please make note of this before you order.
• All canceled orders over $1000 paid with a "Credit Card" will have a 5% credit card processing fee that cannot be returned.
• All canceled orders over $1000 paid with a "Shop Pay Installments" will have a 6% credit card processing fee that cannot be returned.
