We continue our series of articles on off-road wheels and today we are going to show you what does it take to install Ford Excursion 38 inch tires or smaller 37″ wheels. First of all, we want to go over a couple of benefits of getting larger tires. Number one is the improved ground clearance, which allows you to explore the new challenging paths on the way of your next 4×4 adventures. Second is the improved overall diameter of the 38″ wheels, which makes the truck literally unstoppable even on the paths with oversized obstacles.

Ford Excursion 8 inch lift on 37 tires
If you’ve seen Ford Excursion 38 inch tires than you definitely know how good they look in comparison with 35s. Although the installation of heavily oversized wheels requires major modifications of the suspension and driveshaft components. The center of gravity is going upwards, which will seriously change the driving characteristics of the vehicle and affect the stability. Driveshaft spacer (differential drop) is often required to help compensate for length changes due to the lowering of the axles.
The factory tires are significantly smaller, so 6-8 inch lift kit will be required to clear the new tires and ensure normal wheel travel. Although, depending on the suspension and wheel configuration trimming may still be necessary.

*Since the suspension modifications and the installation of the oversized tires require advanced measurements and depend on many parameters, such as the vehicle sub-model, trim level, state of the suspension components, aftermarket upgrades, etc., we highly recommend to confirm fitment parameters for your particular vehicle with the sales representative of your lift and tire supplier before making a purchase. The recommendations in this article are presented for general informational purposes only, so we are not responsible for any problems with the wheel and tire fitment or any other damage that may occur to your vehicle.
