How to Address Tire Concerns

This guide addresses tire-related issues for your 2020 Toyota Tacoma, focusing on reported symptoms and modifications. From tire shine concerns to upsizing and fitment, we'll cover the common issues. As one owner shared, "Long time member first time poster, Wanted to wait til I got the new wheels and tires before I posted pics in here haha. After 2 long years of ownership and trips I finally pulled the trigger on some new wheels, Always thought the steelies didn’t match the MGM and I’m in love with the new look." (source).

Symptoms

Owners have mentioned a range of tire-related symptoms and concerns, many stemming from modifications or cosmetic care. One area of concern is dry rotting. While not explicitly a symptom, the worry is that improper tire care products may be a contributing factor. Owners are conscious of tire shine products potentially drying out the rubber over time, leading to premature aging.

Another factor discussed revolves around tire size and fitment, impacting handling and ride comfort. Owners frequently discuss traction in relation to the tire size and type chosen for their vehicle. The goal is often to improve off-road performance while maintaining acceptable on-road characteristics. This often involves upsizing tires.

The cosmetic aspect of tire care has also been raised. Owners are interested in maintaining the appearance of their tires using products like tire shine. However, they are also wary of the potential long-term negative effects of these products. It's important to balance the desire for a clean, shiny tire with the need to protect the tire's integrity.

Finally, tread compound hardening is a long-term concern. While not directly reported as an immediate symptom, this is a potential consequence of tire aging, especially when combined with factors like improper storage, excessive UV exposure, and the use of potentially harmful tire shine products. Maintaining proper tire pressure and rotation can help to mitigate these effects.

Most Likely Cause

The primary cause stemming from owner discussions is suspension travel limitations when upsizing tires without proper modifications. This is connected to rubbing issues when adding bigger wheels. This can result in tire wear and tear as well as handling problems. Many owners are actively seeking to improve the appearance and performance of their trucks through wheel and tire upgrades. This goal often involves installing larger tires, either for aesthetic reasons or to improve off-road capabilities.

The challenge lies in ensuring that these larger tires fit properly without causing rubbing against the fender liners, suspension components, or cab mounts. When the tires are too big for the available space, they can rub during turns or when the suspension is compressed. This rubbing can damage the tires, the vehicle's body, and the suspension components. Owners often have to use heat guns to solve rubbing issues, as well as chop cab mounts.

The amount of available suspension travel plays a crucial role in determining the maximum tire size that can be accommodated without rubbing. With limited travel, even a relatively small increase in tire size can lead to contact with the surrounding structures. Therefore, it's essential to carefully consider the suspension setup and the intended use of the vehicle when selecting new tires.

How to Diagnose

Diagnosing rubbing issues stemming from suspension travel and oversized tires requires a systematic approach.

1. Visual Inspection: Start by visually inspecting the tires and wheel wells for any signs of rubbing. Look for scuff marks, scratches, or worn areas on the tires, fender liners, suspension components, and cab mounts.
2. Turn-to-Turn Test: Turn the steering wheel lock-to-lock while observing the clearance between the tires and the surrounding structures. Pay close attention to areas where rubbing is suspected.
3. Suspension Compression Test: Compress the suspension by driving over bumps or dips, or by manually pushing down on the vehicle's body. Observe whether the tires make contact with any part of the vehicle.
4. Measurement: Use a measuring tape or ruler to measure the distance between the tires and the closest points of contact. This will help you determine the amount of clearance that is lacking.
5. Documentation: Take pictures or videos of any rubbing issues to document the problem and aid in finding a solution.

Tools Needed:

• Measuring tape or ruler
• Flashlight
• Camera or smartphone

Step-by-Step Fix

Addressing rubbing issues caused by suspension travel limitations and oversized tires may involve several steps, depending on the severity of the problem.

1. Heat Gun Application: If the rubbing is minor and localized to the fender liners, you can use a heat gun to reshape the plastic. As one owner shared: "Barely rubs with fender liner, I need to break out the heat gun" (source). Apply heat to the affected area and gently push the liner inward to create more clearance. Be careful not to overheat the plastic, as this can cause it to melt or deform.
2. Cab Mount Chop (CMC): For more severe rubbing, especially on the cab mounts, a cab mount chop may be necessary. This involves cutting away a section of the cab mount and welding a new plate in its place to provide additional clearance. As another owner shared: "Lift: 2.0” front, 1.5” rear Cab mount chop" (source).
3. Lift Kit Installation: Installing a lift kit can increase the ride height and provide more clearance for larger tires. However, it's important to choose a lift kit that is appropriate for your needs and to ensure that it is installed correctly.
4. Wheel Spacers: Wheel spacers can push the wheels outward, creating more clearance between the tires and the suspension components. However, they can also affect the vehicle's handling and stability, so use them with caution.
5. Tire Size Reduction: If none of the above solutions are feasible, you may need to reduce the tire size to eliminate the rubbing. Choose a tire size that is known to fit without modifications. As one owner stated, "Currently sitting on 265/70R18 Falken AT3’s, looking to move up to 285/70R18 Toyo Open Country RT Trail (pro maybe) tires. I can ask Ai all day long and get mixed answers." (source).
6. Alignment Adjustment: Ensure that your vehicle's alignment is properly adjusted. Incorrect alignment can contribute to rubbing issues and uneven tire wear.
7. Fender Trimming: In some cases, it may be necessary to trim the fenders to create more clearance. This is a more extreme measure, but it can be effective in addressing severe rubbing problems.
8. Bump Stop Adjustment: Adjusting the bump stops can limit the amount of suspension travel and prevent the tires from rubbing during extreme compression.

Parts and Tools Needed

• Heat gun
• Welding equipment (for CMC)
• Lift kit (optional)
• Wheel spacers (optional)
• Smaller tires (optional)
• Alignment equipment
• Cutting tools (for fender trimming)
• Bump stop adjustment tools
