Hi guys

Looking for some grippy track tyres.

Car is going to be used for some track days.

205/55
225/50

or bigger? WHY ?

 

Is the car going to be street driven mostly, with some track days, or is it going to be ONLY used for track days?

If you'll be driving on the street, I'd go with Dunlop *specs, B'stone R11's, or Yoko AD08's.

If track-only, I'd go 225/50-16 front, 245/45-16 rear R-compounds on the stock wheels.
Why? More grip.

 

Car will be used for optimistically 30% track use.

Are those larger sizes ok on the standard wheels?


Anyone tried N2 filled tires on the track?

 

The larger sizes above *are* ok on the standard wheel sizes.
Depending on the specific tire model, you might end up with fronts that visually *look* much beefier than the rears with those sizes, though!

For your usage, I'd definitely go with Dunlop *Specs, B'stone R11's, or Yoko AD08's for 70/30 street/track usage.

IMO N2 fill isn't worth going out of your way for or paying much if any extra $$$ for. On a lightweight formula car with big tires with low pressures, which is *WAY* more sensitive to temperature/pressure variation, yeah, N2 would be the way to go.

 

in R888 or Ra1's most things being stock I'd go 225/245
Ra1's will have more life than R888's but they are still overkill for street
