Tire Size Basics
Tire size is a key factor in Jeep customization. It affects how your Jeep drives and handles. Choosing between 35 and 37 inch tires can change your Jeep’s look and performance.
Understanding tire size helps you make the right choice. It ensures your Jeep performs well on and off the road. Let’s explore the differences and impacts of these two popular tire sizes.
Differences Between 35 And 37 Inch Tires
35 inch tires are smaller and lighter than 37 inch tires. They fit more easily on stock or lightly lifted Jeeps. 37 inch tires are larger and wider. They offer better ground clearance and a more aggressive look.
With 37 inch tires, you may need to lift your Jeep more. They can require trimming of fenders or bumpers. 35 inch tires usually need less modification. The larger size of 37 inch tires adds weight, which affects fuel economy.
Impact On Jeep Performance
35 inch tires provide a good balance between off-road ability and daily driving comfort. They improve traction without too much strain on the engine. 37 inch tires give better off-road clearance and can handle rough terrain better.
Larger tires like 37 inches often reduce acceleration and top speed. They may cause more wear on drivetrain parts. Regearing your Jeep helps keep power and performance balanced. Smaller tires put less stress on suspension and brakes, making maintenance easier.
Off-road Advantages
Choosing between 35 and 37 inch tires for your Jeep greatly affects off-road performance. Larger tires boost your vehicle’s ability to handle tough trails and obstacles. Each size offers unique benefits that enhance your Jeep’s off-road capabilities.
Understanding these advantages helps you pick the best tire size for your adventures. Focus on traction, ground clearance, and handling to see how these tires perform on rough terrain.
Traction And Ground Clearance
37 inch tires provide better traction on loose surfaces like mud and rocks. Their larger footprint grips uneven ground more effectively. This improved traction reduces slipping and helps maintain control.
These tires also raise your Jeep higher off the ground. Increased ground clearance prevents the undercarriage from hitting rocks or debris. It allows you to cross bigger obstacles without damage.
In contrast, 35 inch tires offer good traction but with slightly less clearance. They suit drivers who want balance between off-road ability and on-road comfort.
Handling Rough Terrain
35 inch tires handle rough trails well while keeping steering responsive. Their lighter weight compared to 37 inch tires makes turning easier. This helps in tight off-road spots where maneuverability matters.
On the other hand, 37 inch tires excel in extreme conditions. They absorb impacts better and provide a smoother ride over bumpy terrain. This makes long off-road trips less tiring.
Choosing 37 inch tires means sacrificing some agility for added toughness. Meanwhile, 35 inch tires offer a good mix of control and durability for most off-road situations.
Regearing Needs
Upgrading your Jeep with 35 or 37 inch tires changes its driving dynamics. Larger tires add weight and affect gear ratios. Regearing is often necessary to keep your Jeep running smoothly. It adjusts the axle gears to match the new tire size. This helps maintain power and drivability. Understanding the regearing needs prevents strain on your vehicle and improves performance.
Why Regear Larger Tires
Larger tires require more torque to turn. Stock gears are designed for smaller tires. Without regearing, your Jeep loses acceleration and power. Regearing restores the right gear ratio for bigger tires. It improves hill climbing and towing ability. Your engine runs at proper RPMs, saving fuel and reducing wear. This keeps your Jeep responsive and strong on roads and trails.
When Regearing Is Essential
Regearing becomes essential if you use your Jeep off-road or on hills. Heavy-duty trails need more torque and control. Towing or carrying heavy loads also demands regearing. For daily driving on flat roads, it might not be urgent but still helpful. Those with 37 inch tires should almost always regear. It prevents damage and keeps driving smooth.
Effects Of Skipping Regear
Skipping regearing leads to poor acceleration and sluggish response. The engine works harder to turn large tires. This causes higher fuel consumption and engine strain. Transmission and drivetrain parts wear faster and may fail. Shifting becomes rough and the Jeep feels underpowered. Long term, skipping regearing can increase repair costs and reduce reliability.

Installation Challenges
Upgrading your Jeep with 35 or 37 inch tires offers impressive looks and off-road capability. Installation, however, is not simple. Larger tires often need changes to other parts. These changes help the Jeep run smoothly and avoid damage. Understanding the main installation challenges can prepare you for the process. Three key areas require attention: fender and bumper modifications, wheel backspacing and offset, and suspension adjustments.
Fender And Bumper Modifications
Large tires may rub against fenders or bumpers when turning or driving over bumps. To prevent this, trimming or replacing fenders and bumpers is common. Jeep owners often cut or modify plastic splash guards. Some choose aftermarket high-clearance fenders or flat fenders for more tire clearance. Bumper modifications might include trimming or changing to a design with better tire clearance. These changes ensure tires do not catch or damage the body during normal driving or off-roading.
Wheel Backspacing And Offset
Backspacing and offset control how far the tire sits inside the wheel well. Improper settings cause rubbing on suspension parts or fenders. For 35 or 37 inch tires, wheels with less backspacing or different offset are needed. This pushes tires outward for better clearance. Choosing the right wheel specs prevents interference with brakes, control arms, or shocks. Proper wheel fitment keeps handling safe and reduces wear on suspension components.
Suspension Adjustments
Suspension changes support the larger tires and keep ride quality. Lift kits raise the Jeep body higher for tire clearance. Shocks and springs may need upgrading to handle extra weight and size. Adjusting suspension geometry helps maintain steering and stability. Without these changes, tires can hit the frame or suspension parts during travel. Proper suspension tuning also improves off-road performance and avoids damage from rough terrain.
Fuel Economy And Driveability
Choosing between 35 and 37 inch tires for your Jeep affects more than just looks. Fuel economy and driveability change with tire size. Understanding these effects helps you make the right choice for your needs. Larger tires can change how your Jeep feels on the road and how much fuel it uses. Let’s explore these factors closely.
Impact On Gas Mileage
Bigger tires increase the weight your Jeep must move. This added weight means the engine works harder. As a result, your gas mileage drops. The 37 inch tires usually lower fuel efficiency more than 35 inch tires. This happens because larger tires have more rolling resistance. They also affect the gear ratio, making the engine run at less efficient speeds. Expect a small but noticeable drop in miles per gallon with larger tires.
On-road Vs Off-road Driving
On paved roads, bigger tires can make your Jeep feel less smooth. Steering may feel heavier and acceleration slower. The ride might become noisier and less comfortable. On the other hand, off-road driving benefits from larger tires. The extra size helps clear obstacles and improves traction on rough terrain. The 37 inch tires excel off-road but are harder to control on highways. The 35 inch tires offer a better balance between off-road capability and on-road comfort.
Cost And Maintenance
Choosing between 35 and 37 inch tires for your Jeep affects more than just looks and performance. It also impacts your wallet and the time you spend on upkeep. Understanding the costs and maintenance helps you plan better and enjoy your ride without surprises.
Tire And Equipment Costs
35 inch tires usually cost less than 37 inch tires. Larger tires need stronger wheels and sometimes new suspension parts. You might need a lift kit to fit 37 inch tires properly. Bigger tires also require gear changes to keep your Jeep running well. These extra parts add to the total cost quickly.
Upgrading brakes might be necessary with bigger tires. It keeps stopping power safe and reliable. Buying all this gear is an investment. Consider your budget and how much you want to spend on your Jeep.
Long-term Maintenance Considerations
Bigger tires wear out parts faster. They put more strain on your Jeep’s drivetrain. You may need to check and replace components like axles and bearings more often. Fuel economy drops with larger tires, leading to higher fuel costs.
Wheel alignment needs more frequent attention. It prevents uneven tire wear and keeps handling smooth. Tire rotation and balancing become crucial to extend tire life. Keeping up with these tasks saves money in the long run.
