Default 1/8th scale tyres.....how low do you go?

Just wondering (and I know it affects setup) how low you guys will run your tyres. I normally true to 74.5mm give them a couple of runs & trips through the truer then bin them around 70-71mm but I'm going to give a couple of sets another go this Sunday and bin them around 68-69mm.

Your thoughts?

Hi mate, I usually ditch them at the 70 mark, find the car gets a little hairy lower than that, but see, there is still rubber on the rear but the problem is the fronts, 63 is low.

I gave this a shot awhile back. If you look at the roll out chart (Mugen Seiki) you will see that 16/19 49/46 at 76mm is really close to 17/20 49/46 at 70mm. I measured actual droop of the car and reset it. In the front I was able to obtain the same droop, in the rear I came up 2mm short with the screws all the way up.
63mm Fronts, 70mm rears. On track performance; the car had more steering responce, lap times for this track stayed about the same. Some where around 15 mins of run time I noticed that the steering begain to fade and around 20 mins she was pushing like a frieght train. I had a ton of tires cut so I ran the car that race and it was fun. That was the end of scientific experiment #154879658.120347 . 70-71mm there lookin for a trash can...
