Track day tyres

Post by Markl17 » Wed Aug 12, 2020 3:12 pm

Hi
I use Nankang na 2 r tyres.i have just taken them off to put the road wheels back on and noticed the front left has a ripple in the inner side wall I will post a pic but hard to see.
It looks like the side wall is de laminating but this is only a guess.it was very hot on Sunday and I was running the tyres at 1.7 bar hot.was this pressure to low or was it just the heat? It would be nice to have some opinions so I do not destroy any more tyres.
Also replacement recommendations would be helpful
Thanks mark

That’s way too low for 1500 Kls of car in that heat
You probably should have been on 32 pounds not 25
I would advise that you buy Federal 595 RSRs for track day semi slicks

I've had 5 sets of 595 RSRs and, if dry weather is forecast, usually put the wheels on the car to drive to the circuit, do the trackday and drive back on them. I'd say I got an average of around 7 full trackdays out of them with this usage. The front outer shoulders will wear most, so swapping front and rear pairs helps even the wear a bit. I've even managed 11 trackdays by reversing a set of tyres on the rims to use the better shoulders!

Beware using these tyres in very wet conditions when tread is less than 3mm. Cornering gets quite interesting!

I think I will order a set is 235/40/18 the best size to buy for stock wheels? This is the size of the nankangs I wrecked.

Looks like the pressure was too low and you might have hooked a curb.

Hi Mark,
235x40 is the best size for most on track or road.
The Federal RSRs are good value for money and can last approx 9 open pit lane track days
depending on conditions and driver. You can run them at 30 psi on road and 32 on track, they have a stiff sidewall.
You should run camber of 11/2 to 2 degrees depending on speed of cornering and front wheels straight ahead.
Curbs are there to drive on ( there part of the track ) ;)
And what Casey (Malcolm) said
Have fun
Pete

Riding the curbs is fine, it's just when you drop in the hole just beyond the curb that it can hurt.

Saw an MX-5 "track weapon" completely remove the inner bead from the rim doing this at Kirkistown, despite the warning in the briefing, and the holes being pointed-out in the pre-start track walk.

Well done, let us know how you find them.

Based on my experience and many other "trackies" on here, you'll love pushing these on track! The grip and confidence they give powering through corners is brilliant.

Are federal 595R's road legal? Can you drive to the track with them? Or do you swap them somehow once there?

Just be very careful with them on public roads in the cold and wet.

I drove around Oulton Park on brand new 595RSRs in the wet and was impressed by the grip. I found they were "OK" in the wet until the tread got down to ~3mm, then you had to be cautious.

Re: pressure, I've run dozens of track days and sprints on either Toyo R888R or Yoko A050s. I tend to set pressures 'cold' at 26psi, then let them rise up to 28 or so.
