There are many reasons to get bigger tires on your vehicle. Getting your vehicle to sit higher, get over larger objects on the road, or even just for a more aggressive look are some of those reasons.\u00a0<\/p>\n\n\n\n
Bigger tires can have a negative effect on a vehicle’s fuel efficiency or miles per gallon (MPG). This is because larger tires can add more weight and increase rolling resistance, which requires the engine to work harder to maintain speed and ultimately burns more fuel.<\/p>\n\n\n\n
In addition to the increased weight and rolling resistance, larger tires may also require a change to the gearing of your gears in your differential. This is necessary to keep up the efficiency of your vehicle. When you add a lot of weight to the vehicle you may want to look into regearing because the vehicle was designed to be most efficient at a particular range of weights. To keep it short the vehicle\u2019s engineers designed a car to work one way with specific-sized tires and for the most part for a specific weight. When you start to mod your vehicle (which you should do!!)<\/strong> then you are throwing your vehicle out of spec.\u00a0<\/p>\n\n\n
