Tyre pressures .....

Hello all,
This is my first post here. I owned an S1 Elise a few years ago and went to the dark side with a few other cars but just bought an 05 N/A Exige. I do the AEMC sprint championship so will be running the Exige in this. I have T1R’s on it so can anybody give me base set up with tyre pressures to work from. My Elise used to be VERY changeable with tyre pressures.
Many thanks,

Mark.

best thing to do is change the tyres imo :slight_smile:

Ive driven a s2 exige on track with t1rs and i couldnt believe how little grip they had. Id switch them for some 48s and start off with 22/24 f/r. HTH cheers Ed

Thanks but 048’s are not an option as I am roadgoing. I have to have 1a’s…Grrrr

A048’s are fine on the road as long as you are careful in the wet. They can aquaplane if you hit standing water at speed, but otherwise they are fine in my experience. If you intend to take your car on track, A048’s are essential as the Lotus developed LTR versions give terrific grip in the dry which cannot be matched by most other road tyres.

Erm… don’t understand, you say roadgoing?

Because the A048r�s are road tyres.
And you�re sprinting!

I have T1R�s on my car, as winter tyres, and just because they clear water well, but I don�t rate them even as a road tyre. The thing is that the car�s weight is not enough to work the rubber, and the T1R�s casing is too soft.
But hey, if you like them that�s you. I�ve played with pressures on track and couldn�t get a sensible result.
Just don�t expect to be near the front, they don�t have enough grip in the Exige/Elise.

Apart from the A048�s, tyres that I also rate highly are Kumho ECSTA V70, and they come in 3 compounds.

I think Mark is referring to the fact he’s competing in a class for road-going cars. This will restrict his choice of tyres to either original factory fitment, or a list of specifically approved tyres. A048s will not be on that list.

Thanks, but Brendan is right, I am in a “roadgoing” class. I have to have tyres in list 1A of the blue book. 048’s and the Kumho’s are 1B’s. I will just have to play with pressures and see how I get on, I know they will not be great, but in my class everybody is in the same boat !

the A048 is a standard fit to the Exige so how can they not let you have it ?

because he’s not running an Exige

I am running an Exige, but the MSA rules state I must run tyres in list 1A of the blue book. This does not take into account what is OE on the cars.

Oops, my mistake. I misread your post about your previous Elise, and misunderstood the rules

I’ll get my coat

No probs at all, you were only trying to help !

I know of a couple of sprint cars that have used T1-Rs very successfully. I can’t be much help with your pressures, but the wear on the tyre was very important. As new the blocks are quite tall and you get quite a bit shifting, but once the tyre had worn down they were brilliant.

I know of at least one person who was getting the tyres cut down to about 3mm of tread and he ran very well on them (albeit with a heavier car). Good luck to you.

Thanks, Sounds like a good idea. I think I will get them shaved then. Trouble is my first event is Sunday, so need to get things in gear !
