Just depends on what sizing they have available and what is required by a marque, series, etc. Many of the cars have very different F to R diameters. For example, the 997.
First number is the width in cm, so 2=240cm wide
Second number is the diameter in cm
Third is the wheel size in inches

Drove for the first time on slick tires. Man what a difference and what a thrill.
Car feels so much more controllable and stable. As if driving on rails.
First time and on very old slicks and even though i had a passenger with me, I was able to gain 10 seconds !!! on a previous best 2:04 lap, so are now at 1:54
...
Car looks awful with these wheels but he, if it shaves 10 seconds off per lap![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)

I do have a question about the 10 second improvement over MPSCups. IMO, that's a HUGE differential. Did anything else change since the last time you were there? Conditions? Maybe you are a much better driver

Many folks here have driven a gamut of tires on the track and, in my experience, there are only a handful of seconds between fast R-comps to slicks. 10 seconds leads me to believe something else significant changed.

Now thinking how to move on from here ...... do not have a trailer license (you need a special license here to trail over 750 kg)
Do not have a trailer and my car (volvo V70R) can only pull 1600 kg total.
So maybe this was a one off experience, but knowing me it was just a starting point
(maybe get a roof rack to start with)
Damn
ha ha

24-64-18 24 = 240 mm ( tread width ) 64 = 640 mm ( tire Diameter ) 18 = rim size
converted for standard sizes 240/35/18 is close
The size of rolling diameter for a 64 = 25.2 inches or normal for the rear of a 996 GT3
The size of rolling diameter 65 = 25.6 inches
The diameter 68 = 26-3/4 inches way to big for the ABS compared to the front rolling diameter

@ Himself. I am only tracking for one year now and had never been on a track before. Guess it's the learning curve combined with tires. Personally i feel always a bit intimidated by my GT3 even when i just step into the car in the morning heading to a track day. Kind of a nervous feeling. I have a full track day prepped E36 BMW too and i never had that with the Beamer. Guess the speed comes as soon as you are able to be in balance with the car and be less intimidated by her (him ?)
And that's where for me the slicks came in as a feeling of extra security.
So i guess at my level of tracking, it's all between the ears, and gaining speed is all about confidence. I am sure you can set the same lap times as i was doing on Pilot Sport 2 with a good driver ;-) Same track was lapped in a 944 Turbo Cup on slicks in 1:45. For true racing drivers slicks or no slicks is pure physics and math and has nothing to do with confidence (i guess)
If you're interested here my previous fastest lap (2:04) not so long ago so you can see the differences
