A little update, after my fronts wore past half way they are considerably louder. I think most would find it excessive.

245/35-18 ($121/tire)

You mentioned you run the 235/40-18 size. Is that because the 595 RS-R is wider than your typical tire (of the same size)?

The 'official' section width of the 595 RS-R is very close to the RE050A RFT (at the same size), but I've seen comments on forums that the 595 RS-R are wider in practice.

You mentioned your suspension setup above. What's your alignment settings?

Karl.

Yeah. The 235/40-18 is about the size of a 245/35 but in a sense do look a bit beefier.

I run M261 18x8.5 square with 245/35 Federal 595 r-sr up front and 255/35 in rear but it's close up front with -2* and 10mm spacers + a slight fender roll. The 245s are def closer to a 255 PSS or a 260 equivalent of most street tires (THEY'RE WIDE)

What other tires have you tried on the track (HPDE or lapping)? How do the 595R-SR's compare? Are they adequate in terms of grip, and feedback? Ive heard good things about them, and they are on the affordable side too if I recall...

If you want to spend money buy RE-71's. If you want to save alittle money buy the 595 RSR's. Are both of these tires identical? No. But for less than half the cost you get 95% of the same performance. Plus you can drive them everyday if you don't mind the noise of a Semi-slick tire
