The 215/45/16 rt-615k is recommended for a minimum 7 inch rim, so you shouldn't run it on stock rims
Mixed reviews on them, ok for short sharp work but any extended period on track and they go greasy
I'm going to try a set of RSRs

Ah, thanks for that. Surprising that 10mm more tyre width would mean a wider rim. No track work for me, just want a really grippy street tyre in the dry.

You getting the rsr's from tyre power?

Yes
I've got 2 sets of rims, I'll prob only use them at the track. Get some re003s for the road when they do the 4 for 3 deal.

Got the RSRs on
140 treadwear compared to re003 220, so they won't last long
Road noise, I don't really notice anything major. My pog is obnoxiously loud on jandal though.

Grippy?

Chased pressures a bit at the track last night
Pre-reading suggested a fairly high hot pressure, around 38psi, to stop side wall flex
Seemed reasonable at that didn't seem to chew them up. Front left copped a bit as it always does but not as bad as the re003. I think it may have been running the re003 a bit soft I can't remember what pressures I ran them at that track last.
The pog is normally a bit tail-y if you're aggressive through the esses with the re003 and no rsb. With the rsrs and the rsb on hard it was pretty solid.
Will probably do Collie in December on them I push a bit harder there as it's more forgiving.

Blue9N3 if you get the newer RSR-R they have a treadwear of 200 compared to the earlier RSR which is 140, so if you're worried about longevity they might suit you better than the earlier 595's.

Just noticed for the first time after 3 years that the recommended pressure on the fuel cap is 38psi....I'm assuming that's a cold pressure? Been running 34 for some time now. Tried 38. Steering much better, wheel spin far worse...

yep cold pressure 2.6/2.4 bar or vice versa from memory. Yeah if your on a decent tyre with a stiffer sidewall you will be able to get away with lower pressures that help straight line grip under power like you found. The 38psi they recommend is a one size fits all safety recommendation for monsoon, dry, snow, hot, cold for nanna and the family. While you sacrifice lighter steering, fuel economy and aquaplaning resistance you'll proabably find more outright grip on the pressures you've been running in the dry if the sidewall stays reasonable.
