XB4 '15 tyre wear

[Hans Wynants]

Hello , i have gone from the XB4 '14 tot the '15 last month .

i mainly drive on an astro track ( Orra in Arendonk Belgium) . fully out of astro . and when dry with Schumacher minispike Yellow.

with my old 2014 i can race my tyre's untill they are almonst completely gone. the front tyres would also wear faster than the rear tyres . still have plenty of grip to drive fairly good lap times. less steering obviously butt still ok. the only times i would get in trouble was when driving brand new tyres...


now the 2015 is way different. i drive the new car in shorty setup , with at the moment extra weight on the chassis , under the rear mid axle . the difference i feel directly is that the car drives better with brand new tyres , but as soon the tyres are worn like approx 60% , the grip will dissapear in the rear! the rear of the car will slide faster and the bite when on throttle is nog good anymore...

cane someone tell me what i am doing wrong?

my setup is pritty soft . needs to be for the bumpy astro.

thanks .
