FAQS
What year to stay away from Lexus RX 350?
It’s wise to be cautious with the 2007, 2008, 2010, 2016, and 2017 models. These specific years have been flagged for a higher number of reported issues, ranging from oil leaks and transmission problems to interior components not holding up as well as you’d expect from a Lexus.
Why are 35 tires so popular?
35s do increase load compared to stock, but they’re typically much easier on the truck than 37s. That means better long-term reliability and fewer surprises. For daily drivers and family trucks, that’s a big deal. The 35-inch tire market is massive.
Is it bad to have my SUV tires at 41 PSI?
It isn’t advisable to fill your tire to this pressure for everyday driving. At max PSI, your car does not handle as well, braking is impaired, and you could risk dangerous blowouts. Over-inflation can also cause the center of your tire’s tread to wear out prematurely and reduce the lifespan of your tires.
Is 35 psi too high to drive?
Maintaining the recommended PSI range is essential for optimal vehicle performance, safety, and tire longevity. The ideal tire pressure, typically between 32–35 PSI, is set by the car manufacturer to ensure balanced tire inflation and proper road contact. Following manufacturer-recommended tire pressure guidelines improves fuel efficiency,
What is the best tire pressure for highway driving?
Maintaining the specified air pressure in your tires is essential for vehicle safety and long-lasting performance. The ideal tire pressure for most vehicles generally falls within the 28–36 PSI range, ensuring balanced tire inflation and proper road contact. Correct tire inflation improves handling stability.
