What Gears For 35 Inch Tires?

When you are choosing to increase your tire size, you should not forget to change your gears as well. For example, what gears for 35 inch tires will work smoothly? Let us find out in the article below

If you have some experience running bigger vehicles, you must also be aware that when you drive a car with a disproportionately sized wheel, you will experience some loss of power. 

Bigger wheels sap the power out of the steed of the vehicle. This power deficit in the car will be very prominently visible when the car is climbing, towing, or loading cargo. 

If you wish to compensate for that loss of power, then the most efficient way is to regear the axles on your vehicle and then match the ring and gear ratio to match the size of the new tires. Ideally, you should maintain a gear ratio of 4.56 Turin with a 35 inches wheel

How To Figure Out The Ideal Gear Ratio? 

You can follow several methods for selecting the ideal gear ratio for your car. You don’t have to worry much as these methods follow some basic math, charts, or formulas. You need to decide the correct pinion and ring ratio. 

The most effective way to identify this ideal gear ratio is to lower the percentage of the tire diameter over the stock tires. For instance, if you increase the tire diameter by 40%, you should also increase the gear ratio by 40%. 

This method will help you to maintain an ideal balance between the gears. Sometimes it might not always be possible to maintain the same ratio between the axle and the bags. At that time you can go for the next best alternative. 

You can also go for a lower gear ratio than what the people or the mechanic recommend, as the ideal gear ratio is open to interpretation. Some people feel it is perfect for a higher gear ratio vehicle, and others believe it is feasible to go for a lower gear ratio vehicle.

Why Do We Need To Regear The Ratio? 

Automobile and vehicle manufacturers spend millions and millions of dollars on research and testing, then decide on a particular set of wheels for their vehicle. 

When you change the tires’ size on your car, the engine calibration is thrown off because the manufacturers calibrate the engine for a specific length of tires. We need to regear the ratio of the vehicle again after changing the tires. 

Many people make the mistake of adding different components such as power mods to their vehicles. These people end up installing bigger wheels than the stock tires. With the more extensive set of tires, the engine will have to work harder to overcome the power loss. 

It is good that there are many after-marketplaces where you can get your wheels calibrated. The axle ratio you should opt for depends on the vehicle and several other factors.

Other Modifications To Consider

While upgrading your truck or vehicle to bigger tires, you can also consider making more changes to your car. 

  • There are plenty of variables and situations in the modern vehicle, and you can change the truck’s performance drastically just by changing the engine Or transmission calibration. 
  • One of the most exciting variables for truck optimization is vehicle speed. If the input speed of the vehicle is wrong, then the gears or the computer systems in the car will not be aware of the correct time to shift the gear and transmission. Then there are things such as fueling and engine timing that the engine will also be unaware of. 
  • Changing the speedometer is a simple step that can help the car to improve its performance while simultaneously also increasing the engine’s longevity. Some products available in the market will do this calibration for you. You should remember to change the speedometer when you change the tires size and the gear ratio on your vehicle. 
  • You should install new directions with your fresh pinion and ring gear set. Changing the engine and car bearings is also another essential step when modifying your car. There are complete installation kits available in the market; you can get these kits based on the type of axle in your vehicle. Some of the items present in these installation kits are bearings, spacers, shims, seals, hardware, and other components. 
  • As you are already dabbling with axles at this stage of the modification. You can also install another axle upgrade if you wish to. The size of the axle also changes along with the size of the tire diameter.

Is It Safe For You To Install The Gears Yourself? 

In the majority of the cases, not everyone can install the gear kits themselves. It is not just about installing the gears. Instead, it is also about setting up the correct ratio for these kits. 

You can leave this task to a professional who has experience installing ring and pinion installations. The entire installation process requires some special tools, skills, and knowledge. 

The person doing the installation should know about bearing preload, improper gear patterns, etc. If your truck has an incorrect bearing preload, it will result in unwanted axle noise. It will also reduce the lifetime of the bears and gearings. 

Frequently Asked Questions

What gear ratio is best for 35-inch tires? 

Ideally, the ratio you should run with your 35 inches tires is a 4.56 gear ratio. This ratio will provide you with a decent fuel efficiency when moving at a very high speed. 

If your gear ratio is correct, you will also be able to compensate for the lost power because of the bigger wheels. The gear ratio will also give you enough low-end power to throttle through different obstacles easily. 

Is the 3.73 gear ratio good for 35-inch tires? 

You can run a 3.73 gear ratio on your truck if you want to. It is not that your vehicle won’t move or not run properly. It is just that with a gear ratio of 3.73 and tire diameter of 35 inches, you will lose some power. This gear ratio is going to slow your truck down. You are also going to lose out on some mpg. 

You can run your truck if you have no option at this gear ratio, but ideally, you shouldn’t run it at this level. When the gear ratio on your vehicle is not correct, there is also a chance of high wear and tear on the gears.

Is a 4.10 gear ratio good for 35-inch tires? 

A 4.10 gear ratio is acceptable for 35 inches tires. This ratio is decent if you get a 4:1 transfer of your vehicle for off-road adventures. When you go up from a gear ratio of 3.10 to 4.10, you’ll notice and experience a massive difference in your driving experience. 

The gear ratio of 4.10 provides a mechanical advantage to the vehicle. This gear ratio is a low-end gear ratio that doesn’t need the engine to put in more effort to do the same amount of work. 

Your engine will get more pulling power and higher rpm. You’ll find rowing, towing, hauling, and off-roading more straightforward with this gear ratio. There is also a higher fuel economy because of the higher RPMs in the vehicle.

Do you need to Regear for 35-inch tires?

Yes, you do need to regear for a set of 35 inches tires. But when you change the wheels of your truck, you will need to regear the car so that it can run efficiently. Regearing is required because the vehicle or the truck manufacturers build the engine and the truck according to a standard size of wheels. 

If you don’t regear your truck, you will see it losing power when climbing, towing, or hauling a load. Setting up an ideal gear ratio will give you more low-end power to force through such moments quickly. 

What’s the purpose of Regearing a truck?

The primary objective of regearing a truck is to improve its performance and efficiency. The regearing of the car will improve the top speed of your vehicle, fuel efficiency, and the overall conditioning of the truck. People generally switch to bigger tires for offloading purposes. 

When you switch to a set of bigger tires, there are changes required in the axle, tire rolls, tire resistance, tire rotation, tire weight distribution, etc. 

If you don’t make any changes to these components, your truck will not function properly, and you will experience resistance or drag while driving it. 

The best solution for this problem is to keep the percentage change in the tire diameter and the gear ratio constant. If you are increasing the size of the tires by 16%, you should also increase the gear ratio by 16%.

A Few Final Words

This article talks in detail about why you need to regear a vehicle. You also learn about the ideal gear ratio for your car if you run it on a 35 inches wheel width. 

Your engine efficiency needs to get the gearing ratio right. If the gearing ratio is incorrect, the engine will have to work harder. This will cause excessive wear and tear on the machine, which is not suitable for prolonging the engine’s life.
