Tyre Pressures For The Track

[AzzurrA]

Hi All

I'm heading out to Queensland Raceway tomorrow for a Sprint day, and was wondering if someone could give me some ballpark cold pressures to start off with? (Car is an R32 GTS-t)

The Tyres Are:

Front: Toyo Trampio - 205/55/16

Rear: Falken Azenis RT-215s - 205/55/16

I was thinking of aiming for around 38psi hot on the front and 36psi hot rear? How does that sound? Has anyone had any experience with different pressures, running either street or semi-slick tyres on the track and want to share their findings?

Thanks

Jason

(And yes, i did do a search but couldn't really find much on the topic)

What size rims?

I have found, starting with standard pressures of around 34-36 for road tyres works, but with semi's I know a lot use around 28. The rest now is up to you......adjust to suit your preference.

SK, what's with the rim fetish mate

rims are standard R33 rims, so 16 x 6.5

I actually had typed a rude come back, but it wasn't in my style, so I deleted it.

:lol: :lol: :lol:

If he had 205/55/16's on 9's I would suggest a lower pressure than the same size tyre on 6's.

Anyway back to the question at hand. Actually more questions, what model Trampio are they? The sidewall construction determines the tyre pressure, and that varies a lot. The Falkens will like mid 30's hot, I wouldn't go over 40, they crown rather badly on 6.5" rims.

But if they were on 9's, then low 30's would be the go. Size does matter. Sorry that rude comment almost snuck out.

All it says on the sidewall is: Toyo Trampio GU:WN

Hope that helps

Oh well, go with the same pressures (mid 30's) as the Falkens. I suspect you may have to go up a bit closer to 40m, but try the mid 30's first
