Tyre pressures for "mixed" tyres?

General General Lotus Talk

My Exige is about to do it’s first trackday under my ownership :slight_smile:
It currently has partly worn A048’s on the front and newish 888’s on the rear.
I know this is not ideal but as the fronts still have a bit of life left in them and as I’m far from being a driving god, I’m going to run like this until the fronts need replacing.

Can anyone tell me what cold tyre pressures I should be starting out with?
From reading previous threads, I’m guessing 21 front and 23 rear but would like someone to sanity check that.

Thanks in advance.
Steve

Edit to add - car is an S2 Exige S

are you at Combe on Thursday?

get them hot and adjust them through the day

don’t think 48s and 888s are different enough to consider pressuring them differently to having say 48s all round

No, not at Combe, I’m going to the Motorsport Events day at Odiham at the end of the month. It’s local and hopefully will be a smooth introduction to Lotus handling :slight_smile: (I’ve been driving Caterhams for the past 10 years)

Scosh, what should I be looking for pressure wise, when the tyres are up to temp? 24/26?

i use 26/28, though i’m no expert

With A048’s I use:

23 front, 26 rear in the dry
26 front, 29 rear in the wet

Excellent - that gives me something to aim for.
Cheers guys
