Have TOYO changed their Block Pattern ?
Discussion
Tyre on the left is an old T1-R. On the right you have something with a much newer tread pattern that mimics all of the high performance tyres on offer from the premium brands; Conti Sport 6, Michi PS4, Goodyear F1 etc.
The theory these days being the longitudinal groves allow the tyre to cut through standing water to maintain traction and minimise aqua-planing, rather than trying to shift water out the side of the tyre. Assuming they haven't buggered up the compound I'd say you're in a better place than previously. Safe driving!

Just look at the sidewall it will tell you what it is.
As you know the one on the left is a T1R, the one on the right looks like a Proxes Sport and according to the tyre specification has far better wet road handling than the T1R so you need no worry there. Personally I would always keep all 4 the same on a car that has a propensity to swap ends if provoked.

I think there is some level of confusion here.
The Toyo Proxes timeline reads as follows:
T1S (ancient, introduced ca. 1999-on)
T1R (really old, ca. 2004-on)
T1 Sport (ca. 2009/10-on)
Proxes Sport (the latest)
The tyres our man has bought are either the T1 Sport or Proxes Sport (probably the latter)

Where does the R1R fit into that?
I have run R1Rs in the past and think they are a great tyre, but not sure they are still made, not in any size of interest to me at least.
Completely different tyre, it wasn't even called Toyo before they did an E-marked version (the ones I had back in the mid-2000s were branded as Trampio R1R). They're basically a track day/minor league motorsport control tyre that can be used on the road, a half way house between Toyo's road car tyre range and the R888 if you will.I have run R1Rs in the past and think they are a great tyre, but not sure they are still made, not in any size of interest to me at least.
Compared to the triple eights, they are a lot better with standing water but they are really not confidence inspiring when it's cold and wet outside. My personal experiences with them on an intrinsically stable Saab (at least that tended to plough straight on when aquaplaning on rain sodden motorways rather than swap ends) would dissuade me from using them as a road tyre on TVRs.
Interesting comments. I ran them on a Mazda MPS with a big turbo and 350 ish BHP.
I didn't want a track day tyre as it was my daily driver, so I wanted something that would cope with rain and had a decent amount of grip in all weathers. Anyway, I really liked them. (I ran winter tyres for half a year, so wasn't too worried about performance on a frosty morning).
Edited to add, your comment that they are a halfway house between a track tyre and a road tyre is spot on.

I use the R1R as the "Every day" tyre on my 340r, everyday being quite a lose term for such a car but you get the idea. The closest to that available for most TVR's would be something like Yokohama Advan Neova AD08. They are great tyres and if you have the money go for it.
R888, R888R, 048R, 038R some of the Khumo, Avon etc.. track day tyres are very very grippy in the dry and pretty good in the damp but cant handle standing water or extreme cold, in fact it states dont use them below 5c
Here is a small demo of my ability to drive quickly with R888 on a track with a little standing water. Having won the race before I was probably a little overconfident but you get the idea.
