I want to increase ground clearance with larger tire

Can you describe "high speed breaker" in more detail? Are they there to slow traffic down?

 

That is way too much.

Changing tire sizes seems extreme, comes with drawbacks. I'd advise to just slow to a dead crawl, or avoid such roads (if possible). That's my tactic here (they're called speed bumps in North America). Typically they're 3~4 inches, and especially if they're very abrupt, the only way to go is dead-slow.

Even if you increase ground clearance, while you may clear, if you're hitting them at any speed they're causing stress to wheel bearings and suspension.

The ones I particularly dislike go across the road on a diagonal, causing you to rock side-to-side, hard on the neck.

 

Yes, diagonal is best for low cars^^^

 

You'll need to install a 40mm lift kit, in order to install taller tires - otherwise they'll rub and possibly rip out your plastic inner fender liners.

Look at this website: PRIUS 2016-2022

 

Coil-over modifications are the most expensive option and it messes with your alignment. The body lift is the least expensive option and any alignment issues can be adjusted out without replacing additional equipment. Going beyond a 40mm lift will require additional suspension equipment and adjustments.

IMHO; find another 'expert'; it sounds like this guy wants to empty your wallet. Those lift kits are also available in the European market and probably the Asian markets - you just need to do some research.

That link (#7) answers all your questions, including maximum tire size.

 

Yes going up to a 60 series tire would be the easiest way to raise your ride height some. You can alwa try them and see if they rub.

 

The lift kit looks so cool !!

 

I had these lifts installed on my ‘22-Limited
It sat so low that my wifey would scrape front end entering & exiting standard residential driveways, retail centers, and parking lot space concrete bump stops.
The 1.5” lift did the trick.
It set me back abt $900 after the parts ($300 for discounted blemished spacers), installation ($500), and alignment ($100).
But it was worth it.
I didn’t add larger tires to the equation.

P.S. could I have installed myself & saved $500? Probably, looks very straightforward in the videos

 

If you have the tools and everything yes it's a very easy installation, especially since your not taking apart the shock assembly so you don't need a spring compressor. The biggest pain was taking apart the rain tray in front to get to the upper three bolts. It only took me about 4 hours to do the entire suspension on this car.

 

Congratulations on your lift kit. One reason it was difficult to guarantee that 215 60r 17 tires would not rub is that they are 2.6 inch in diameter more than your 215 45 17 tires.

Tire Size Comparison

There are posts here at priuschat about custom wheels and tires that fit without rubbing in many different sizes and the accessories needed if they are too big and do rub.
@black_jmyntrn may have some suggestions for you with your lift-kits and what size tires are possible to install without the worry of rubbing with the many possible rubbing spots for your particular needs.
