I need a bit of help with the new control tyre, it doesn’t mater how hot the ambient temperature/track temperature is, (It was hot at the last QLD State Round) we can not seem to get enough heat into these tyres to get them to work!
Is there anyone else in the country running the following AO48's: 195/50R16 on an AWD Racecar??
The above tyres are not the right size tyre for my car. I am running factory rims. The factory tyres size was 205/50R16. Could this be the problem???
The 48's seem to be a hell of a lot stiffer and they are a different compound!
What tyre size are you running and what compound are your tyres???
I know that NSW or VIC IP have run on the new tyre yet?

Brendon,
We are running the 48s on the WRX over here at Barbagallo. We use 245/45R17. Our first round couple of weeks ago was extremely hot. Qual and 1st race air temp was over 40C. For those tyres got up to temp nicely and were fine. In the 2nd race at night in cooler air, tyres didnt get as warm, but due to fixing accident damage after second race didnt get a chance to try anything to improve for 3rd race so again didnt get as warm as we would have liked.
Used to have 235/45R17 in the 32s that worked really well, up to temp well and lasted a whole season on a set.
Havent had a chance to do back to back test yet. 1st round was on short circuit that is only used once a year, so can't read much into it. We are hoping to do some testing next week using 32s and 48s back to back and see how we go.
Cheers

Re: Yokohama AO48 - Control Tyre Info????
So now a few have had a run on them, what are the thoughts on the new tyre and any differences with the old???
Faster or slower??
More consistent / Suffer from fade??
More shoulder wear or less??
More camber or less to make them work??
Best temperature ranges??
cheers

Re: Yokohama AO48 - Control Tyre Info????
Unfortunately for us (NSW Competitors), Wakefield Park has never been the place to make an advantage out of new (green) tyres, so it may be a little hard to say for sure yet.
Anyone using them for the first time will need to have a think about their wheel alignment settings, and adjust accordingly.
I must admit that I was a little surprised that after the weekend due to a minor brake issue (different pad compound) and a few lockups to see hardly any damage to our ones though. Well relieved I must say!!

Re: Yokohama AO48 - Control Tyre Info????
Having never run on the 32s its hard to compare but I was very impressed with the grip levels of the 48s especially on the ripplestrips and coming onto the main straight.
Re: Yokohama AO48 - Control Tyre Info????
rataz, Thank you for your help!!! You are a Legend!!!!
"rdmdog" Your coment: "Are you sure you arent getting too much heat into them Brendon?"
What is it you don't understand???
As I stated "I was strugling to get heat into the new control tyres!!" I am only new to IPRA and I thought that by posting a genuine question, I would get a helpful answer from senior members of this forum?? What give's??
Anyway, I went testing today! Based on rataz's, info I was able to rectify my problem and cut some very very respectable lap times!
I have found the new control tyre to be very sticky, just as good as the old AO 32R! I have had to set up the car differently. However, the new tyres still squeal under load, but do hang on!! So who cares!!!!

Dog is always one of the first guys to offer helpful advice and assistance, perhaps he either misread your question or thought you might have been getting them too hot - you don't have to be a rocket scientist to figure that out...
One thing is for sure - abusing people who are trying to help you won't get you far...

Hey Baby, ease up on the red pills!!
If you would like to contribute to the two test days and thought process and subsequent time myself and my team have done with the new tyres, then Ill spill all the beans. However, Im sure youll understand that the info we have gleamed from our RWD car on higher profile 15" tyres may not transfer anyway.
Maybe I should have typed "....did you use a pyro across the tread of the tyre?"
It could well be that you are the first to have a good hit out on the new tyres in an AWD LM car.
I am happy that you found a result with your own testing though.
(This reply was initially typed while Boppa was doing the same, Im a little slower on the keyboard!) Thanks for the kind words Boppa, pity you werent being so kind on Friday night to the drunken Goulburnians
It did occurr to me that we had only done one short day at Oran with the new tyres when I wrote the initial reply and as such were still thinking through what changes we would be making. Edited by: rdmdog at: 3/29/06 6:25 pm

Cool,
Sorry if what I wrote was deemed to be abuse? It was not my intention!
Anyway, I agree and do understand that no one will share info with a fellow competitor and have them run quicker than them. I had no right to ask!
You are right to suggest that the info you have acquired from testing a RWD running on higher profile 15" tyres would not translate to an AWD car running a 195/50R16.
What I don't understand is why anyone on either 14" or 15" tyres are supplied with an M compound and anyone on 16" & 17" tyres can only purchase an MH compound tyre and therefore are forced to run a MH compound. In the US, an M compound is available in 16"! You would think that there would be a differance between the two compounds wouldn't you???
Re: Yokohama AO48 - Control Tyre Info????
Check with Yokohama - the M and the MH compound are actually the same
I don't know why they are labled differntly, but the people who know say they are the same

Mr. Sceptic here
Sorry for being sceptical...but I can't see a company like Yokohama labelling tyres differently if they are the same. Sound to me like someone wants us to believe they are the same.
From an importer/distributor/supplier point of view - it's much easier to control stock quantities if there is only one stock item, instead of two.
Re: Mr. Sceptic here
I spoke to a couple of people at Wakefield for Round 1 and they were more than happy to share information. Whilst we didn't use the info specifically it was a starting point.
We started out on a this spec and then did tyre pressure checks after every race before we found a good setting for the Honda by the last race.
Re: Mr. Sceptic here
Why would we want to believe the Techs and our trusted distributors who have been doing motorsport tyres for 20 plus years when the marketing people have so obviously got it right

M- to help light early model dinosaur cars keep up with late model heavy cars than have 4wd,4ws,abs,traction control,stiff chassis,independant suspension,flybywire,larger brake and wheels .......
MH on a late model tyre probably wont burn them up during the whole race like a dinosaur will.( so another advantage, how many do late model cars need)
thankyou.

Re: M-MH
Machmech the late model cars as you pinted out are heavy, hence they need all the help they can get.
With M compound the dinosaurs probably have a good chance to do better in qualifying, and to get away early in the race.
The heavy LM cars just may last a bit better and might come back toward the end of the race IF their tyres don't go off (remeber that generally they are heavier).
Sounds reasonably fair to me, but I'd rather get to the fornt during qualifying and run away and make the other catch me than do it the other way round.

Re: M-MH
Most unlike you Simon to leave such a big gap........
Wakefiled Park Round 1
Qualifying = first LM car was 8th on the grid, 3 seconds off pole. First 4 cars were RX7's
Race 1 = first LM car was 4th (well done Scotty) but 11.5 seconds behind after 8 laps. First and second were RX7's
Race 2 = first LM car was 7th and 31 seconds behind after 10 laps. First, second, third and fourth were RX7's
Race 3 = first LM car was 4th (well done Scotty) but 26 seconds behind after 12 laps. First, second and third were RX7's
Doesn't seem to me that the EM cars need much help "keeping up".
Cheers
Gary
PS; with only 2 LM cars on the grid for the Trophy race maybe they need a lot more help.

Re.Re:M-MH
Thanks for your thoughts Gary
I agree with U2L99, the balance seems fair to me at the moment. Hence my answer above, there are +/- on both sides of the fence.
we all have our own agendas.
maybe this topic will be more relevant in 10 years time when some late model cars have had the amount of development some early models have.(thats if we don't change the rules and allow bigger restrictor that when combined with all of the advantages of a late model make early models redundant)
just my opinion

P.S Gary you haven't seen the sides of my car, I don't leave gaps un-filled.
