That said, what is best for your vehicle depends on your budget. Bigger tires cost more than smaller tires, so you have to factor in price while buying tires.

Your needs and tastes also determine what the best size is for you. Some owners run small tires on their wheels because they want a stiffer sidewall. Meanwhile, some owners want bigger tires since these give vehicles an attention-grabbing profile. Evaluate your needs and tastes carefully and select a tire that matches both criteria.
