Hankook RS3 Tyre pressures

The short answer would be 38psi hot and monitor the wear pattern and temperatures. Adjust based on that and the feel of the car. ie the High pressure end of what Dean Evans suggested. The lower pressures will be for cars with less body roll/stiffer suspension.

Don't listen to the people saying 31-32 psi for this tyre on a standard MX-5.
You will wreck the outer shoulders, which have limited tread when they are new to begin with on RS-3's.
The first thing to keep in mind is that this is still a road spec tyre so it needs higher pressure. People mistake these for R-Specs.
You will get a sawtooth wear pattern (Middle section worn on an angle, and outer shoulder worn on an angle), which is pretty much unavoidable on a standard MX-5 being dríven to its limits. I used to do that when I had standard suspension on my SE, and still do in my Dads standard NC.


I have been using these tyres in 225/45/15 on my 04 SE for 3 Supersprints, a Marulan day and a Bathurst Conrod to Start Line run.
I have -3.25 camber up front and -2.5 at the rear. Tein Street Flex, 7KG front, 6KG rear, standard front 23mm sway bar, no rear sway bar.
I have found running them at 33-34 psi hot to be pretty good for my car and setup.
Using a laser temperature meter I achieve even temperature across the face of tyre on the working side. On the non working side, it is hottest on the inside and coolest on the outside. I beg that no one wears out their keyboard telling me that a laser temp gun is not the proper way, I already know, it gives me a rough guide.
I get a little shoulder wear on the outsides, the rest of the tyre is wearing evenly.

I will be at the club track day tomorrow, if you see this between now and then, cool, I'll look out for you tomorrow any way.
Car 13 Green NC.

Very important point Luke has made, which we've not really taken into account - suspension setup.

I don't have much negative camber on my car, so the way the tyres wear will be very different. It's a street setup done by Stu at Spinning Wheels.

Thanks Luke.

Your advice was useful took a heap off my PB throughout the day. The tyres are awesome.
