I put 17s wheels off a 2017 Toyota Camry On my 99 Toyota Avalon that came out with 15s wheels. I put 215 55 r17 tires on Has no rubs and no scrubs. Anything I should watch out for will my speedometer be off or anything.
Larger wheels, even if they are compensated for by putting on low-profile tires, can potentially cause issues with the vehicle’s suspension and brakes which were originally engineered for the smaller wheels due to the extra weight of the wheel (metal). Larger wheels give your vehicle’s springs and shock absorbers more weight to deal with, so you’d have to upgrade that - but now opening up a chain reaction of further upgrades (and $$) and not worth it. Also, because of the added weight it will require a longer distance to stop. Bigger wheel/low profile tire will also make for a harsher ride as you have less tire sidewall to absorb the bumps on the road as well as increased chance for wheel/tire damage and blowouts. Fitment might seem fine at the moment, but when loaded with people and baggage it could rub. Finally, bigger wheels can throw off your computer systems (speedometer/odometer) so you’d have to adjust them to compensate.
In short, I don’t recommend doing that.
Turns out the 17s are lighter I thought about that and picked each up and the 15s were definitely heavier

There are online calculators for that.
If no rubbing, no scrubbing, … all you have to do now is check tire diameter - must be pretty close to the same for speedo to be accurate. If it’s the same, all is ducky ( … ducky is good!). Your ride will be harder, your steering response will be sharper, … you probably will like it! Mind you, it’s a ‘99 Avalon, … make sure the rest of the car is up to snuff: shocks, springs, bushings, et. al.
