New Semi Slicks - Do they need "running in"?

Postby 85AW20v » Wed Jun 18, 2014 11:21 pm

What are peoples thoughts. Got the first round of the Taupo Clubmans Winter series and a new set of Achilles 123's. Any particular do's and don'ts? Only the second set of brand new rubber I've had on the car in the 14 yeas I'e had it so not quite up with the play regarding this.... :?
See ya

I've always done some road km's on new semi slicks, unless they're super duper softs (which a 123 isn't).

I have always given mine a run at say 70% to get some heat into them and get rid of the release compound , then let them cool down .
then they are usually good to go .

best time around Manfield to date : 1:19:91

"Understeer" is when you hit the fence with the front of the car.
"Oversteer" is when you hit the fence with the rear of the car.
"Horsepower" is how fast you hit the fence.
"Torque" is how far you take the fence with you.

Yeah - 1 medium heat cycle followed by a cool down
Probably find a qualifying session will do the job as usually you don't get more than 1 or 2 fast laps due to traffic
I used to think that the orange and green tictacs gave you special powers. The orange ones would make you stronger and the green ones would make you faster. So i used to eat some green ones and run around my lounge as fast as i could, then eat the orange ones and try to pick up the sofa. I wish it were true!

^^ what kinloud said. Give them some good time to cool down also and remember to recheck pressures for the first couple races.

Only don'ts for semi's are;
- Never use silicon/tyreshine on sidewalls
- Store out of the sun in cold dark place
- never force it in, you won't be doing anyone any favours..

That made me laugh!! Achilles couldn't be supplied by Sunday so now going with Nitto NT01 which are probably a better option anyway. Only the second set of new tyres I've had on the car in the 14 years I've had it!! Had access to lots of used Targa tyres but there aren't many Targa cars running 14 inch tyres anymore.
See ya
