Can I Fit 33-Inch Tires On 20-Inch Rims: Explained!

You can fit a 33-inch tire on a 20-inch rim without major modification, as long as the tire’s aspect ratio is 285/58 to prevent tire ripping at high speeds. To accommodate the 13-inch discrepancy between tire and rim diameters, the tire’s sidewall should be at least 6.5 inches high. This combination typically enhances vehicle appearance and performance, with no rubbing or scrubbing issues. However, IFS 4WD vehicles may require a lift kit due to potential rubbing against the suspension spring.

This is just a glimpse of the whole discussion. Read more for details.

Can I Fit 33 Inch Tires On 20 Inch Rims?

Yes, you can fit a 33-inch tire on a 20-inch rim without doing any major modification. However, in order to ensure proper fitting and prevent tire ripping at high speeds, the tire’s aspect ratio should be 285/60R20.

Given a total diameter size discrepancy of 13 inches between the tire and rim, the tire’s sidewall should be at least 6.5 inches to accommodate both sides of the discrepancy (6.5 x 2 = 13).

This combination is generally compatible with most vehicles and does not cause issues such as rubbing or scrubbing. It can also enhance the vehicle’s appearance and provide improved performance, efficiency, and grip.

IFS (Independent Front Suspension) 4WD vehicles, however, can present rubbing and scrubbing challenges. This is because the suspension spring in such vehicles is directly affixed to the tire, potentially causing the tire to rub against the spring. To mitigate this issue, a lift kit is necessary. (1)
