Toyo T1R Track day pressure settings?
Discussion
I hate to be the bearer of bad news but new tyres on a trackday is a bad thing. The tyre heat is generated by the movement of the treads. The more tread depth the more heat you'll generate. My advice is to limit yourself to 10 minutes max, after that your grip will be turning to jelly.
As for pressures that depends partly on what springs and damper settings you have. I'll assume you are running on original suspension. T1-R's are not very rigid so you will need to add some pressure to get the best out of the car, I would suggest 28 rear 26 front. Don't make them too hard or you'll get 'snap' oversteer and finally, don't forget to drop them down again before you drive home.

What if you're driving hard on normal roads, are Toyo's going to over heat?
No. Track use is very different to road use. Just trust me on this one. johnbear said:
What road pressures should I be running for fast country roads i.e switzerland.
Toyo T1-R's need a little more pressure than the original fit SO2pp's due to differences in their rigidity. 24/26 is a good starting point, don't go above 26/28 for road use or it'll not cope with poor road surfaces or potholes. tvrbob said:

Hi Bob, I tried to phone you a couple of weeks ago before going on a track day at Croft.As for pressures that depends partly on what springs and damper settings you have.

If I had managed to get hold of you, maybe you could have saved me trashing four new Toyos !!
I ran with 24 PSI all day. OK when the track was wet, but two 10 lap sessions in the dry at the end of the day have taken the edges of both fronts and left all wheels with a rippled finnish! I think this is called 'learning the HARD way'

I haven't changed my number If I had managed to get hold of you, maybe you could have saved me trashing four new Toyos !!

I'll PM you from the other forum with my mobile number so that you can check if you have the right one. If you change your tyres you'll need to keep the old ones and put them back on for the TOH track day

The tyres will recover, the rippling should go once you start to use it on the road. However, nothing can replace actual tread depth!Ho Hum
