Toyo Proxes R888R 

Simply amazing. Car makes 450whp and it hooks up perfectly with these Toyos. Came from Nitto NT555G2s, which were like driving on ice, and by comparison, these Proxes are night and day. Floor it in 2nd and she simply rockets forward. 7k rpm 2-3 shifts, no problem. Nittos almost killed me, these Toyos simply stick and perfectly match the car’s power output.

Well, I have tried many semi slick tyres in the past including pilot sport cup, r888 and recently replaced kumho V70A hard compount, which I can directly relate these to.
The wear rate might be higher on these ones, although I can't tell at this time, but ouaou! ...what a big step up in Performance!
The grip is much better with these tyres, although I put slightly smaller section in the rear of the Car and I know have 235 40 17 square instead of 215 45 fr and 245 40 rear! The cornering speed is increased, the rear traction is better, maybe there is less of warning when they will start to slide on good pavement, but not big deal, you can learn it. They warm up fast and the huge difference in relation to the kumho is on more slippery than Ideal surfaces - the traction there is amazing, the kumho's would let go without warning but these slide progressively and you have plenty of time to catch the slide! I will never go back to kumho's with this tyre and the only tyres that I might try in the future is federal fz201 or hoosiers! The cold pressure that I use is around 26psi! Last, but not least, the comfort in relation to kumho's is excellent, they absorb rough surfaces like nothing else I have tried before, I have run over a little stone and I didn't even realized it although I run kw variant 3 coilovers!

These are amazing track tires. Even feel great just driving around town, though with a 100 treadwear rating, you don't want to do that much as you will use the up pretty fast.
Do NOT drive with them when it is wet. I had to drive in a mist the other day and it was scary. They are not meant for any wet pavement at all. They tell you that when you buy them and they mean it.

These tires have worn incredibly well, way, way beyond expectations. I live in Las Vegas where it never rains or drops below freezing so run these on the street year round. I have 25k miles on them now and they are probably ready to be replaced but I will likely run them for a bit longer (no rain here). Turn in and dry traction is amazing. Turn in, in particular, is astounding. Noise is loud. Loud on the highway and really drone about 45mph pretty loud. I am used to it and don't care though. These tires plus high performance brake pads doubles the capability of my little Fiesta commuter daily car. Love it. Feels like the car lost about 50 horsepower when I put them on because the chassis can handle so much more suddenly.

Love this tires have had 3 sets on 2 of my vipers, not good on wet roads but amazing on dry roads, I also don’t care about the noise, the more than make up for it on grip!

Got my first set of these after changing up the car and moving to a square setup, used exclusively at HPDE track events. The grip and stability were phenomenal for the first 3-4 track days of the season and I set several personal bests at a couple tracks. The grip fell off quickly once the tread got down into the wear bars and gets spooky without warning when the tires decide to let go. I'll be going to a grippy 200TW tire after this - these last about as long as Hoosiers but don't grip quite as well and really only have the advantage of being (relatively) streetable and usable in the rain.

If you are in a wheel-to-wheel class, I would go Hoosiers over these. If you're in time attack, you are probably on RT660s or another similar spec 200TW tire. The only real use case I see for these is for occasional HPDE events on a car which is otherwise a weekend canyon carver. I couldn't get a full season out of R888Rs and would consider that to be unacceptable considering I live in a snowy area with a limited amount of decent weather per year, but these do grip exceptionally well if you can deal with the poor wear rating.

Don�t buy these tires if you want to compete in the rain or film vlogs on the highway. Buy these tires if you want to have good cornering and acceleration balance.

I use these tires for HPDE/Track days. They are very capable tires in dry conditions and provide superior grip to road tires, yet are more durable and last longer than slicks. If you are looking for a compromise between street tires and slicks these are for you. I would not recommend them for use in wet conditions.
