Fitting 55 profile in place for 60, any real problems?

[codenamecueball]

So I've got a 2020 Hyundai Ioniq with 16" wheels, 205/60/16 Michelin Energy Savers on it. One has a slow puncture, one has a screw in it just beyond the repair area. As I'm in Scotland and for some reason an energy saver costs £170/corner, it's time to swap all four tyres for all seasons.

When I first looked, Costco thought my car used 205/55/16 which the previous generation did, but the facelift went to 60. Dropping down to 55 profile tyres takes the price of a CrossClimate 2 down from £160 to £80.

The speedo already overreads quite a lot so not concerned about that, but will I notice the 10.25mm difference in ride height? Am I taking any actual safety risk using tyres out of OEM spec?

Edit: I also meant to post this here, but must have clicked the wrong forum...

The insurance company may not be keen.
Put the values in here to check how the speedo reading will change.

According to this, only the EV Ioniq uses 205/60s, the rest of the range uses 205/55s.

What does the sticker on the car say (using on the B pillar or in the 'fuel' cap)?

It is the EV and the sticker in the B pillar says 205/60R16

The price for that michelin energy saver tyre is nuts.
It should cost about £90 like the 205/55/R16 version, it was standard fit on F30 era BMW 320d/EDs -- but I see it's about double the price for some reason.

Contemplate a 215 width if cheaply available, to get close to the original rolling radius, use a tyre size comparison calculator.

They are about the same price.

EV's tend to be heavier, sometimes their tyres are specifically marked EV.

What load rating does the vehicle state is needed, and does your new tyre choice comply ?

92 vs 91 on most tyres.

Doesn't matter - got a deal on some 205/60s which made them about £108 a corner, fitted at my house today. Job done. Thanks all.

Warranty implications?

There isn't a 10.25mm difference in ride height, there is a 10.25mm difference in overall wheel/tyre height but only half of that sits on the road, so it will be 5.125mm lower, so no, you won't notice it.

If your speedo already reads high, it will go higher, but you could always fit one of these & calibrate it using gps speed from your phone.

ETA, didn't get down as far as your conclusion, sorry, but left post in case it helps others.

The difference between 60 profile and 55 profile in that size is 2.05mm in diameter. So ride height change of 1.025 mm, I guess the decimal point was 1 position out.
