How much difference in tire size is acceptable?
If they’re too large, they could scrape on the inside of the fender every time you make a turn. As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle. Wrong-sized tires can put extra strain on your vehicle’s drivetrain, suspension, and braking systems. If the tires are too large, they may rub against the wheel wells or fenders, damaging both the tire and the vehicle body.
