You can fit 18-inch wheels to your Toyota RAV4 as long as you have the correct offset and bolt pattern, but we would advise checking with a wheel and tyre specialist to ensure you have sufficient clearance. This generation of RAV4 came out of the factory with wheels no larger than 16 inches.

However, fitting larger wheels is unlikely to provide better ride quality, and is actually more likely to make the ride quality worse. Larger wheels will usually require lower profile tyres, and a smaller sidewall offers less bump absorption. If you feel the ride quality of your car is particularly poor it may be worth checking the condition of your springs, dampers and suspension bushes, as this may be the cause.
