so back when it was cool to be 140tw, we had a lot of the extreme tires rating them as such, even if their wear was fairly decent, in order to match the other tires.

on top of that, it's not really a crime to overrate how fast your tires wear/underrate how long they last. however, there is something wrong with overrating how long they will last. obviously tread wear is fairly arbitrary but I wonder how many street miles people are getting on these. If they're noticeably worse, someone may say something and these tires may get bumped out of 200tw in the future... just a thought I had

 

In general the older cars are harder on front tires, AYC actually really helps with evening out tire wear as far as I've seen - and without a rear LSD & ACD tune to balance things more dynamically, I think we are stuck with the old regular laws of doing what we can do get the car to rotate, and will just plain mean how we get the car to rotate. putting more grip in the rear, the car will not turn well in an autox situation

 

I have spend lots of time driving a full passive AWD car without any gadgets and there was no difference in the logic! You have to even the work fronts and rears are doing the best way you can or you would leave time out there.

Also, with more rear grip car will be getting more like RWD, but they still make their rears to rotate...so, I am not saying it is easy, just something that is worth doing on cars like ours (or probably any for this matter).

 

yes working the best they can - but that doesn't mean evening out the front and rear - means transferring grip from the rear to the front, for our case.

more rear grip does not make the cars handle more rwd - I know we disagree on this somewhat though, so not really relevant for this conversation.

 

I think it is a good conversation overall, so...

Evening our front heavy cars is pretty hard, but if I would have a choice between 50:50 weight distribution or 60:40, I would go for the first!

Comment about RWD car was that they have lots of grip back there, but they still make them to turn pretty well. So, even if we get more traction in the rear, car can still be made to rotate and it doesn't necessarily means more push/tighter by default..

Overall, once you push the car that gets close to 100% in the front, while doing, let say, only 40% from the rear, that car can not be pushed any more. Pushing it harder will just cook the front tires even more, while still maintaining that 100% or close to it (it can even go down). So, unless you find the way to get more out of the rear tires, you can not go any faster with given setup and driving style.

 

Did you rotate between events?

I think STR guys are getting like 150. Local STU STi said they were basically dead at 95 runs but I'm not sure he rotated them back to front.

I still only have like 38 runs on my 245s. Not sure what I'm going to do with those. Maybe they will be super fancy street tires for the IS300

I'm still torn as to getting 255's for the 17x9.5s I have now, or spending the $ on 18's. I suspect 2016 is going to be more like 2015 i.e. a very light schedule.

 

I mean weight transfer via braking, lifting, trail braking, throttle, etc. etc... Anyway, different discussion.. I'm sure as far as setup goes these guys know what they are doing.

I'm not sure either. I am probably going to just stay on 245s. No nats for me, I'm not gonna plunk down for a new set of wheels and tires just to be a little faster regionally. I'm still not crazy about the 265s decision anyway.

How do your tires look after 38 runs? I personally will be rotating every event, since I pull them off for the trips home. Hoping they last 100 runs or so, plus a track day or two... lol. may just need to go with z2ss. Will definitely be trying these out on the Mini.

 

I believe that, the CS FR-Ss were getting twice the life out of their RE71Rs than my BS Evo.

As a national competitor you should go big!!!

PS: Isn't it time someone made a 2016 STU thread?

 

for those of you getting big tire wear... what kind of spring rates are you running? 12/16? I'm on 8/10, should be considerably lighter on the tires

 

We rotate after every event, sometimes even between each half of the day depending on the number of runs (2 drivers). We also flip them. If you do both you could probably get a hundred runs and 1 track day, maybe.

 

that's about as much as I'm hoping for. i'll perhaps get a fsb in hopes of keeping the front tires a little happier

 

That is about what I am hoping for my car as well. Of course with rotations and flipping half way through which happens to be right before the next event in the spring!
I have about 60 - 70 runs on mine and they are down low on the outside edges, but other one is good so, hopefully few more runs on them!

 

It's probably time for a new thread:
