Installation:

Many manufacturers offer manuals for installing lift kits onto certain vehicles; however, some setups are quite intricate, requiring some welding or cutting to add some necessary components. In this case, having a mechanic or a few knowledgeable friends around will help make the job go smoother.

Additional Modifications: 

Upgrading to taller tires also means that some components may require part upgrades or some tuning to compensate. For instance, a truck’s engine is tuned at specific gear ratios to propel the vehicle. When adding taller tires, the gear ratios must be changed accordingly, since the engine has to spin significantly more weight with the new tires. You will also be required to purchase a speedometer re-calibration tool, so you have an accurate reading. Again, consult with more experienced individuals for further insight.

Highway Driving:

Larger, wider tires can sometimes result in instability on roads or a noisy, uncomfortable ride, particularly at high speeds. Also, more aggressive off-road tires tend to wear faster on the highway and traction might not be as great as you would expect on wet roads. 

Weight:

Larger tires are more substantial, which can put a lot of strain on your suspension, particularly if it is a stock suspension. Trusted, durable suspension components and lighter aluminum wheels can sometimes help to reduce the stress.
