Autocross Tire/Wheels
I put 39 LBS in them cold and did not check them again... I am still just concentrating on finding the course and driving it better... traction does not seem to be an issue as much as taking better lines, finding the right breaking points and transitioning the from braking to power on smoothly to load the suspension so I can use the new found traction! But I sure had a blast yesterday. When I saw the final results I see that some of the last runs passed me in times - but I am still right in the scrum of far more experienced autocrossers with similar cars and tires. I was the fastest of 5 Minis including a JCW so I guess I have those bragging rights!
too much fun - congrats on moving up in the shark tank!
y'might try more in the back - I'm running a full STX setup so YMMV but I generally am 38/48 front to back.
better rotation with more pressure has been my experience, but it gets to be a handful in slaloms with too much.
36/36 on the street, which avoids any twitchiness
cheers,
Charlie

I believe that 15 may be the best. They are typically lighter in weight, first of all, then say a 205/50/15 willl improve the gear ratio for better acceleration. 225/45/15's would be agreat combination.
If you want to confirm the size on the tires, I think you should consult this with a good tire installer, because he knows, what fits best and what works best.

are you running those tires on the x-lites? and is your car lowered at all? do you think there would be room for a 1" drop with them? im trying to decide if my 05 mcs would fit the 225/50/r16's with 1" drop (h&r springs with bilstein sports).

When I was running R comps, the first run was usually good for either a long slide or a spin, as the back end would have no traction to speak of.
But on a warm day, and once the tires had heat - wow!
It's been much debated what the difference is in lateral G, but my own data indicates about 1.2 on stickies, and about 1.1 on treadwear 140 rubber.
Of course the stickies have much stiffer sidewalls, turn in faster, and are a bit less forgiving of slip angle so the overall driving experience changes in more ways than just max grip.
I was banished to ASP for the first few years of running the Works car (due to the "trunk kit" status of the dealer installed option at the time) and I don't regret my trip to the dark side. Too much fun.
Nice not to change tires so often though (lazy me).
Cheers,
Charlie
lol, the first run was always kinda spooky!
This is interesting, I've got nothing but grief that x-kites on't fit my 2011 R56 and that 225/50R16 will rub. Is there that much difference between the earlier R56 and the current one? Well, besides the annoying I couldn't get a LSD because they dropped the option.
Making the jump from R-Comps back to Extreme Streets. Glad to see the choices were narrowed down. Admittedly, pressing the "Easy Button" for tire choices (regarding the A6) will be missed... Seeing my bank account dwindle by $1000 twice a season won't.
