I’ve run 265/35/19 fr, 275/35/19 rear in AR1 and also 275/35/19 square on stock wheels. It’s fine to run these sizes, you can check on the Nankang website for confirmation 👍

@@samellio I see. Also have you tested A052 in stock sizes? I'm seeing that they are also avalible

I've run a few sets of A052's but in 18's and part worn. Coincidentally, I'm picking up some A052 in 245/35/19 and 275/35/19 tomorrow that look almost new. The52's are fast tyres but in UK are very expensive and wear out very quickly. When they're worn they pick up punctures so you don't want to use the last bit. Time wise, I never beat any PB's on them but the ones I used had been raced on and were nearly dead. I'll try a couple of sets of nearly new A052 now, so interested to see how they do 👍

I’m afraid not, it looks to be more of a road tyre.
