Was very productive...started day with 6 session old rubber then put another 8 sessions on them..so they were spent... never dropped out the 46s. Made afew changes that kept the kart as good as could be given the tyre. Should work on the race tyre.

So I reckon you had about 180 odd laps on them by the time you binned them? Seems about right what we found when going through tyres. After that many laps, fit for the bin :unsure:

I know you can of course gain a few tenths from new rubber, but what's the rest of the degradation ratio like? I assume first 20 odd laps they are optimum then fall off slightly. But do they stay in that window up until they are fit for the bin, or do they slowly degrade with each session?

Fair enough! Is it mostly club members on Sunday test day? Not many eBay specials I hope? :rolleyes:

With the sports theres a 5/6 lap window that your achieve the optimum lap...there then drop a tenth or two in that first session

Your next session will be about 4 tenths slower... by 4 sessions to 5..your be half a second to 8 tenths off that first 5 lap optimum lap.

Also as they get older they take longer to switch on... so a goal was to keep times within that 8tenths time def despite age of tyre. Its bloody hard to do.lol

Now that is some great information, top man Chris! For sure something to keep a note of for future reference.

My last PB set on new tyres got smashed by 4 tenths when I put my rebuilt engine on (Also on another new set of tyres). The last time out testing I was 4 tenths off my current PB with a set of tyres which are a few months old with 130ish laps on them.

So that encouraging to know a new PB is for sure in reach on the right day with a new set of boots for sure!
