It wears 235/50 on 18s and the exact model of Toyo it currently has are no longer made.
Yes I would have said Toyo T1-Rs but as you say, no longer availableI'm lucky I have a set in hand, thinking cap on now for what next
I have in the past used Falken (something like 542 or something) on other cars

Just realised I've asked this before here (thought it sounded familiar).
The answer then was to switch to smaller wheels, which wasn't what I asked
50% profile maybe some of the problem, 18" wheels should be OK unlike 17'sThe answer then was to switch to smaller wheels, which wasn't what I asked
Could have a look for 245/45 or 255/45 more of them arround

But if you want to improve ride quality that is the answer.... The answer then was to switch to smaller wheels, which wasn't what I asked
Google TRC Tyre Calculator and play around with combinations of tyre width, profiles and wheel diameters. Although it's not perfect science it will give you a subjective comfort rating on a scale of 1 to 10 for various combinations. It'll show too that once you go below an aspect ratio or profile of around 50 to 60 ride quality plumets. I've used it in the real world to choose wheels and tyre combinations and it works.
Problem is everybody seems to want to bling up their cars with larger wheels and lower profile tyres and for the life of me I cannot understand why.
Compared with the smaller design on the same car low profile tyres cost a lot more - often hundreds more per set - to replace and not only that they are often a PITA to source with a very limited choice of brand and patchy availability.
Low profile tyres decimate ride quality as the side walls have to be made incredibiliy rigid as any flexing would result in the wheel grinding on the road and because they are so narrow and rigid the wheels are far more succeptable to damage from potholes. Low profile tyres are also, like for like far more noisy, and because of their inflexibility they feed way to much energy into the suspension causing accelerated wear on bushes and premature bearing failure. In addition to all that a larger diameter wheel is inevitably heavier than it's smaller version which adds to the total unsprung weight the suspension has to cope with and makes balancing more of a challenge too.
Quite apart from all that just drive two examples of the same car at 100k, one which has been fitted with the lowest profile tyre available from the factory and the other with the highest. I'll bet you a pint you know which one will have all the trim and fittings inside the cabin creaking and rattling like a can of nails.
On the third world cart tracks our local authorities are pleased to call roads they are a absolute nightmare - so get rid of the large wheels then choose tyres.

All things being equal 17" should give a softer ride than 18", no?(though I appreciate the OP doesn't want them)
The same with the profile ratio more available for 45% than 50%
Agree with the ride but 50 to 45 isn't going to make that much differance unlike going to 40% or 35%
