Having followed modern hatches on ultra low profile tyres, the "handling precision" is used to avoid pot holes and other imperfections. It certainly isn't needed to drive along public roads at even dangerously high speeds.

My 2.5 tonne SUV on 19 inch, 55 profile tyres, will hustle down a road at indecent speed and a lovely ride.
Civic Type R handles the rather bumpy Nordschleife public toll road just fine: https://youtu.be/QYV3yWshHLI?t=109 Hustling comfortably at 245 km/hr, and easily taking sweepers at 185 km/hr.

Does your SUV really provide the same level of enjoyable handling precision in either 185 km/hr sweepers, 60 km/hr hairpins and everything in between, as afforded by the 35 profile tyres?

I made the mistake myself of replacing the factory 225/40 R18 tyres on factory 18x7.5" rims of an earlier model Civic Type R, with 225/50 R16 tyres on Mazda RX7 16x8" rims thinking the smoother ride of the 50 profile tyres would have no handling drawbacks.

I was sadly mistaken, as it was very much like driving on balloons. The high profile tyres produced a lot of unwanted movement and even increased body roll, as the tyres contribute to the overall spring rate. The 16" wheels had to go, as this was totally unacceptable. #-o
Where do you do 185km/h (115mph) on public roads? Just want to make sure I'm nowhere near you... :lol:

My SUV gives me handling that is entirely suitable for public roads, particularly as most of the time one is in traffic on poorly surfaced tarmac. The ride/handling balance is excellent. That t also works well when off road or towing is a bonus too.

I've been in and driven cars on public roads on ultra low profile tyres. Generally, it's an unpleasant experience. On the odd occasion that one finds smooth tarmac with no traffic on it, they can give a few moments of silly fun, but the speeds are generally very much in licence losing territory before the supposed benefits of the "precision handling" can be felt.

I don't know. Maybe I'm just getting old... :?

Never 185 km/hr. However there are plenty of 50-100 km/hr bends in the countryside in the mountains, where precise handling is preferred. Hairpin bends in particular are taken well below the speed limit of either 80, 90 or 100 km/hr. Nothing worse than a vague front end and/or excessive bodyroll IMO.

If I require a luxury car for transporting people, luggage, dogs etc, I will acquire one. I would quite like a large wagon with a manual transmission. :)

That's the Civic Type R's *cornering* speed. :)

The low profile tyres appear to help with handling precision.

.... Thoughts on the news the 2021 18” tyres are based on the rejected 13” 2020 prototypes??
