mine: sportcontact7 (street and one lap track; on tire 0-50 degrees plus wet condition) a052 (two laps track; on tire 10-60 degrees plus wet condition) 03g h1 (track; on tire 30-90 degrees )

a052 more than 10 degrees is ok on cold tire on street

the question is how who measures it. Rarely does anyone take actual measurements while driving. For example, I measure it with a pyrometer after the descent and the readings are around 70 degrees, but I also know that in the arc on the measuring lap the temperatures reach up to 90 degrees. In my opinion, what is more important is the temperature distribution and how the rubber wears out.

NK - new carcass. weight will be similar

a052 is super tires for light cars or short stages. dunlop 03g h1 is better choice for heavier cars and longer stages.

no. 5laps its 40minutes ride. vr2 hl version is for 5 minutes stage. no longer. (i use 245/40r17 for 600kg axle and after 5 minutes tires have 80 degrees and its and of limit temperature). vr2 r7a is good but to light cars for longer stages. vr2 r9a is good for heavier cars for longer stages. but r9a is not so fast like 03g. so in soft compounds vr2 are very quick. in hard compounds there are better choices.

These are Polish liqueurs. They are slower than Polish extreme liqueurs. In general, a friend once tested the first version RGC and compared it with Cup 2, then the RaceGC average mixture was 1 second per 1 minute slower. But rain races, super soft mixture, people recommend that they are exceptionally good. so for the track I would choose extreme vr2 hl as a light car and a short test (tires faster than dunlop 03g h1 by 0.5s per 1 minute), or possibly for a rainy race the super soft version RGC. https://www.odsserwis.com/sklep/?filter_producent=rgc&query_type_producent=or https://www.odsserwis.com/produkt/opony/semislick/rgc-02-fw-225-45-r17/ https://www.zakupopon.pl/kategoria-produktu/opony/opony-sportowe-extreme/

If a guy says that on a wet surface in the rain, the A052 is faster than one of the best UHP tires, i.e. Pilot Sport 4s, then I don't know how you can say that the A052 is not suitable for rain. so Pilot Sport 4s is also not suitable for driving in the rain? unless we say that road tires UHP are not suitable for rain, only super-soft rain slicks. and in fact AR-1 and FZ201 are not suitable for rain. but the A052 is most suitable for rain because this tire is a soft tire, has circumferential grooves and will generate at least 0.9G on water.

my car 930kg has 245 rear and 215 front. can't imagine weighing 1400kg and 235mm tires. 1400kg it should be 245-265 tires without overheating them. Maybe 265 front and 245 rear like new audi rs3
