So i know that my ES350 07 has 215 55 17
i have a chance to get some new tires at a great price bran new micheline X-ice 3 winter tires that i want i was going to pay like 140 a peice for them in my 215 55 17 size.
but i have the option to get a 215 60 17 size for 105 dollars each
wondering if i go up one size will i really notice any issues ?
like i know that is going higher in the side wall.will it take any of the realiability and saftey away from the ride control ?

215/55-17 is 26.3"
215/60-17 is 27.2"

You would be 3.2% over spec.. It could be done but i would advise against.. I mean people have upsize their wheel & tires one inch above spec and have been okay for performance setups with lower axle ratios but changing tires like this is considered okay as long as you're aware your speedometer would be off and you'll be going faster than you speedometer indicates. Your stopping distances will be more lengthy cuz you brakes will work harder to slow a larger diameter tire down, acceleration will also be reduced as well.. It can be done but Most will advise against it unless you car is heavily modded for racing.. I won't do it on a regular car like an ES350.. It could be done but it will be less safe, so NO I wouldn't do it on an ES350..

It won't be a problem from a safety standpoint. The only difference you might see is a speedometer error. You will notice more difference from the tire construction than the tire size.

Note that you cannot calculate tire diameters from the tire size. Tire manufacturers do not use exact sizing when they produce tires. While 1QWKGS4's calculations are correct from a theoretical view, they cannot tell us anything about the true size of the tires. You must get the actual dimensions from the manufacturer, and those are usually on their web site or on the Tire Rack site. Tire sizes as defined by the Tire and Rim Association are overlapping so that many tires could be classified as either of two section widths and sidewall aspect ratios. It's possible that the tire 60 aspect tire you're considering is actually smaller than the 55 if both tires are in the middle of the range and one manufacturer chose 55 while the other chose 60 for marketing reasons.

Case in point: I worked for a tire manufacturer a few years ago. Our 315/35-24 and 305/35-24 tires were made in the same mold. The only difference was one had 315 and one had 305 molded in the sidewall - and the 315 was $300 per tire more expensive.
