Just to make something clear..

R1R is not semi slicks..they are extreme performance tyres..they are step down from Semi slicks..similarly to 595RSR

But of course as you go up the range of performance tyre, the handling in wet will slowly go down..

I've driven the R1R before (fronts only)..I drove from KL to Perak..and after tracking out..I drove up to Gohtong and back down to KL (all teh way raining)

I can say..I didn't dare to go above 80kmh

The tread as I reached KL was about 30% I think

No offense bro..but RSR still not semi slicks..Extreme tyres..that's why still road legal..

More info here

I'm also looking forward to these tyres..but 205/45/16 is about 500/pc last quoted in ZTH @_@

I also gatal..but...$$$$

I can't say much..lol..haven't used any of the 4 tyres you mentioned..

I've only used R1R (2nd hand) at the fronts only at Dato Sagor track..

I guess the all rounder is the PS3? More durable..definitely can't go near the R888, a step lower than the R1R..

I'm guessing the PS3 and T1R is within the same class..but I'd go for the PS3

But don't take my words for it..hahahaha xD

Look at it at a different point of view..

All rounder in terms of grip, durability

Or

Awesome Grip in dry, low treadwear, low wet-grip

Yeap..140..

Extreme tyres treadwear is between 140-160+- range

As for semi-slicks..they are below 100 ratings (depends on the type of compounds)

Theoratically possible for 28k..I guess? Haven't tested it personally yet =P
