Extreme Performance Tire Tests

AutoView's 2025 extreme-performance shootout takes three of the most aggressive R-compound-flavoured summer tires available in the Korean market - the Nexen N'Fera SUR4G, the Bridgestone Potenza RE71RS and the Yokohama Advan A052 - and runs them on a BMW M3 (G80) in 275/35R19. The SUR4G is the staple of Korean sprint racing and goes in as the domestic benchmark; the RE71RS and A052 are the imported reference tires against which it has to defend that reputation. Michelin declined to send a Pilot Sport Cup 2 / 2R for this round, citing a worry about being beaten by tires with prior test wins overseas - so the obvious fourth contender is missing, but the three that did show up cover the price/performance spectrum cleanly.

For 2025 Tire Rack have tested a bunch of extreme performance summer tires, eg 200 treadwear track tires on their new M2 in 275/35 R18.

Tire Rack split this test into multiple parts, doing some testing at their smaller test facility and also going to a big track to do a fastest lap and average lap time test.
