taller tires for comfort

[Loco_Nomad]

I tried to search but didn't get any specifics, will 255/45 R19 fit 2014 Model S RWD with air suspension? anyone can post few pics ? will upsizing help with road noise and make my car more comfortable? sorry, noob here

With those bigger tires, you'd get 1.234567% less wheel revs per mile.

Wouldn't it be nice, if that would get you 1.234567% more range?

Too bad they are wider - the aerodynamics would likely eat-up any gain.

For lower noise, just shop tires with good rating in quietness. Keeping the pressure little lower also makes the ride quieter and smoother (but more floaty).
Wider ones may be helpful if traction is a concern, but 245->255 of the same tire will be below sensible difference.

If lower motor rpm would have helped efficiency they would have used a slightly different gearbox ratio. People with ICE often fixate on lugging the engine in the false belief lower rpm is efficiency because going faster is less efficient. Well going faster is less efficient because of aero losses, it isn't rpm ICE or electric.

Added chassis height and tire width would both have some negative efficiency effect.

The suggestions about researching quiet tires and lowering pressure are spot on Tire Rack has a good reviews feature that will help. Lower pressure within reason may impact efficiency and wear out the tire a little faster.

Buy Continental Silence - I'm on staggered 21's (MS), was on pilots sports - the conti's reduced noise by about 30% - according to my ear.

They're only made in 21", 275/30 and 285/30

Tried today, stock 19" wheels, 235/55R19 fit great in the back... HIT THE CONTROL ARM at the top in the front. Tires would not be able to rotate. Couldn't buy the set b/c of that unexpected annoyance.
