How To Fit Big Tires On Lexus RX300 / RX330 / RX350 / RX400h
Fitting a Lexus RX with big wheels is just a question of time for many fans of the outdoor activities, off-roading and those who often drive on country roads. The majority of modern SUV require some modifications to accomodate 31″ tires. Ideal setup would include 2.5″ suspension lift, .5″ strut spacers (not spring spacers) in front, 1″ strut spacers in rear, + sport Highlander rear struts for extra 1.25″ of lift.
Needless to say that aside of the obvious benefits in the off-road capabilities you’re also improving the visual appeal of your SUV. Taller and wider stance along with beefy tires create an image of a tough truck, ready to handle any challenge you can throw at it.
The driving characteristics of a Lexus RX on 31-33 inch tires will not be changed dramatically so you will still be able to maintain normal ride quality. A slight drop in the gas mileage may be noticed and it should not exceed 1-2MPG. The suspension geometry will remain the same unless you decide to go with extremely low offset, which will widen the track a lot.
*Since the suspension modifications and the installation of the oversized tires require advanced measurements and depend on many parameters, such as the vehicle sub-model, trim level, state of the suspension components, aftermarket upgrades, etc., we highly recommend to confirm fitment parameters for your particular vehicle with the sales representative of your lift and tire supplier before making a purchase. The recommendations in this article are presented for general informational purposes only, so we are not responsible for any problems with the wheel and tire fitment or any other damage that may occur to your vehicle.
