HILLCLIMB & TRACK DAY Semi SlickTires ?????

[AIROCOBRA]

Hi Guys ,
I am running a AE86 in Canberra ----HILL CLIMB & TRACK DAYS . I am running Federal RSR 595 semi slicks 195/50/15 on 6.5 " rims . I have been happy with them running a stock 4AGE NA but recently put a warmer n/a 4AGE ( 101 rwkw ) in . Now the Federals are not quite doing the job ??

SO WHAT IS EVERY ONE ELSE USING & HOW DO THEY PREFORM ?
Here is a proforma to use , I'll rate my experience with the Federals

Tire Brand ------ Federal RSR 595 semi slicks
Size ------ 195/50/15 on 6.5 " rims
Tread wear rate ----- 140 ( usually on the tire wall in very small print )
Comments ----- Happy till went from 68 to 101 rwkw , noticed that after 15mins of constant laping at a track day that they get a bit squirmy . Overall been happy , got bang for bucks --- but now searching for more grip . I will go 205/50/15 with next ones. :thumbup:

sus toyo proxes r1r and the r 888

[Andy San]

I use r888 semis, they are 205/50/15 and I get good wear rates put of them. They are a treadwear of 100

[takai]

Im on A048Rs and get absolutely horrible wear out of them. They go off within a race or so.

The really shagged R888s i put on the car once dropped 2s a lap for me :(

[racsov]

i would start with wider wheels

[AIROCOBRA]

That's great guys keep the info coming , would be nice to know what each of you guys use the cars for--- ie track only , hill climbs etc etc .I have noticed a lot of the MX5 boys use the R888 . They are my direct competition in under 1600cc modified class and don't give much away . I DID NOT REALIZE THAT THE R888 was wear rate 100 . I know that is not a perfect indicator to establish how sticky a tire is , but it is a good start.
Regards Bob

I was lead to believe the Federal's whilst having a R-compond tread style, were not a R-compound tyre.

I have some cooked A048's and they were well past their best so not a good judge, but had just gone completly off, comparable to a street tyre in grip. Pushing 160rwkw through them was quite the task. Even with 120rwkw, could spin them up in 2nd. With 160rwkw would spin them in 3rd on undulating surface.

R888 195/50R15 with 120rwkw was a good match with the tyre comming on and not starting to go off doing 1:24ish laps around Mallala. Was on 7" rim and advise to move on from the 6.5" rim.
R888 205/50R15 with 120rwkw on 7.5" rim. Trying to get the tyre pressure right is hard, starting to go off after 2-3 laps now doing 1:22 around Mallala.

Would recommend the 205 over the 195 as it has more grip and is cheaper than the 195. I would expect that a NEW A048 would be better than a R888, but not last as long (heat cycles). For hillclimbs i would look at the Dunlop D03G's or new ADVAN A050 tyre as they come up quickly to temp.

[charged]

For hillclimbs, track sprints the new A050 seem the goods, Bridgestones, Dunlops seem next best and r888 are next

[takai]

What ive found with hillclimbs is that its extremely hard to get temp into the front tyres. In the old road car (SC AE92) i would always find myself understeering off on the first turn at Collingrove simply because the A032s wernt up to temp. Switched to C-drives and my run times dropped by 0.8s despite being a much crappier tyre.

[stouty]

Ive been using R888's i have 2tg with 92hp. ive used them for 8 hillclimbs and and 2 supersprint days and they are still good. They get to temperature after about one lap at eastern creek and dont go off over the next 3 laps (supersprint being 4 laps be session). I havnt used any other tyre apart from them so have nothting to compare with. They get up to temp quick so they are good for the hillclimbs.

[rokko_2010]

G,day
New to the forum but th r888 are the gun tire at the moment across quit a few forums. Your thred question every where turns up r888. Go for it.

[xero]

ive recently be using toyo R1R's, and are would be a fantastic hill climb tyre, they also go alright at the track too.

on the street they are fantastic and stupidly grippy (i mean stupidly grippy, like you can dive in to corners much faster than you think) when ive been on a few spirited drives. had them at MDTC as well and they were stupid grippy there too, had a few slides but that was because of the bumps on the track (if you've been there you'll understand).

ive also found them very progressive when they let go too. one of the guys i work with runs R888's on his mx5 and loves them, they provide a large amount of grip and he usually get a 3-4 track days out of them.

R1R's and adrenalins on 205/50 15's are about the same price. also R888 in 195 and 205 are about the same price.

how would you compare the r1rs to the re001s adam?

[Konakid]

After being in lawsons rig with both ^^ The r1rs def have the edge over the 001. Awesome value for money but they have a lower treadwear and dont last as long. The trade off for more grip i guess.

what he said.
the R1R have huge amounts of grip in the wet, dry, patchy whatever. biggest trade off it that i reckon ill get just over 6mths out of them not driving everyday.
RE001s are a good street tyre, but have since changed the compound since being made in australia. they used to be 170-180 tread wear now they are 220. even on the micra with 95% tread you can still break traction easily with them in the wet. this is only applicable to common sizes (185/60 14, 195/50 15, 245/40 17 etc etc) these are made in australia, the others are made in japan still (205/50 15 springs to mind)

dont get me wrong i still like adrenalins and would probably best for a skid car, but for grip and price the R1R's are impossible to beat.

[Konakid]

Got some new 195/55/15 RE001 last week and they are made in Taiwan. :(

My last pair were made in Aus, the pair before that, Japan.

[AJPS]

the 195/50 are made in japan

[xero]

i got my 185/55 14's on the micra that say made in australia, also my 195/50 15's also say made in australia...

205/50 15 are made in japan (this i checked when i was looking, was gonna take at least a week to arrive)

[AIROCOBRA]

What is the wear rate figure on the side of these tyres ------------- toyo proxes r1r and the r 888 .

[AJPS]

r1r 140 and the r888 100 (but come in others)

[AIROCOBRA]

Has any one out there tried these new DUNLOP DIREZZA DZ03G Semi slicks yet ??????????

[xero]

supposedly (this is coming from a few MX5 and honda fanboys) the dunlops are better than the R888's, but cost a few dollars more.

but for the best bang for your buck cant go past the R888's.

[Jonny Rochester]

These are my current options:

Toyo R888 185/60R14 $260ea (195/60R14 not listed)
Advan A048R 185/60R14 $249ea
Advan A048R 195/60R14 $259ea

Also Advan A050 would be one to get, but a 14" is not made at the moment.

I only have 14 x 6.5" rims right now. Which tyre?

[jaz_ae86]

R888 for long term usage, Yoko's for short term usage/life.
Said another way: Want a quick time first time out Yoko's. Want to be faster on the same tyres in 6 months and 3 track events later:R888's.

[xero]

+1
the yokos are a control tyre in IPRA and most of the guys i talk about them hate the yokos as they barely last one race. a couple have used R888's on test days and sprints and shit and are usually for a good couple of seconds quicker a lap and will last more than 2 events.

[AIROCOBRA]

Ok Guys , bit the bullet and lashed out on a set of 205/50/50 DUNLOP DIREZZA DZ03G ( SOFT ) Semi slicks . Holy shit ----- straight away 2 seconds quicker at local hill climb . The wear rate is horrendous --- but that's the price you pay to keep up with the Jones. I recon that you would kill them after two laps at Wakefield , but great for climbs.

[Jonny Rochester]

My Sprinter is stripped out and close to 900kg even with a cage. I am about to order the R888 in 185/60R14. It is the classic size tyre for the 80's Corollas, but is it too small? Would I be faster in 1 lap or hillclimb with a 195 tyre? I have heard a wider tyre takes longer to heat up, which is why you run smaller tyres on smaller cars. I wonder if a 195 tyre one a 7" rim would actualy be faster. The old Group-A cars were restricted to a 185 tyre on a 6" rim at one stage. I only have ~95kw at wheels now, and the front tyres get warmer than the rear when trying to go fast. I have only used old street tyres at the track and don't find any difference between 195/60R14 and 185/60R14. I think my fastest time yet has been on Bridgestone RE711 185/60R14 street tyres with only a few mm left on a hot day. Used R-spec tyres were slower (unknown age of tyres), which is why I want new ones. Sorry for the ramble.... $1000 does seam like a lot.

[Andy San]

can you get a 205/60 or 50 profile size in the R888's?

a bit more baloony, but this will work to your advantage when it comes to heating the tyre surface up.

[xero]

yeah the R888's come in 205/50.

johnny i would go a 195/50 15 if you can. again a lot of MX5 guys i know run them and quite a few of other people i know seem to go for that size on the smaller cars. other good thing is that they are cheaper in that size too...

[Andy San]

i know they do a 15 but i think johnny is running 14's (i might be wrong) don't think they do a 50 profile with a 14 inch rim

[takai]

I think they do a 55 profile.

I woudl go the 195/60/14 anyway as im pretty sure its the Medium compound over the Hard in the 55

[stouty]

I think the toyos only come in 185/60 then 205/60 for 14" rim

[takai]

Its a bit dicey, certainly that is what is brought into the country, but http://toyotires.com/tire/pattern/proxes-r888 shows other sizes and the UK site shows different again.

185/60/14 and 205/60/14 are officially brought into the country though.

[AE092]

Have used Kumho KU36's to great effect at Winton. Did 4 full track days plus one in the wet as well as 10000 odd k's on the road before I sold it for $120 (205/50/R15 size). Went to 4 year old Advan A048's and went almost 2 seconds quicker with a few other mods. Currently have Bridgestone RE55S but have yet to try them out.

[stouty]

Just looked on the Toyo site they have 185/60/14 a 205/55/14 and 225/50/14

In terested to see what a 55 profile would look like?

[xero]

185/55 14 on my micra

Sweet cheers xero looks ok think i might lok into the 205 when i get my 7" TE37's

[ae71neo]

Old thread but did you end up getting some 205/55's? Im contemplating getting some R888's in 205/55/14 and putting them on my 14x8's.

[ach_66]

I've have had a set of 195/55/R15 Toyo R1R's on my daily for just over twelve months (got em late oct 2010). I drive the car fairly enthusiastically as a daily, and have run two wakefield days (with 4 or 5 10 Min Sessions in each) in the past twelve months. They are great on the track. They do get squirmish as other have said after about 3-4 laps, but that doesn't mean you still can't turn fast lap times. On the street, as Xero has said, they are ridiculous.

I cannot speak highly enough of them, and they still have plenty of depth, I'd expect to get another 6 months out em, which would equate to about 30000 Km's. Looking to get a set of separate track tyres now, and will definitely be trying the R888's before anything else.

Hi all,

was out at canberra hillclimb yesterday, met bob with his 86, damn his fast!

so anyways i think i will be in the market for some semi slick tyres good for hillclimb/short track events

what are people using these days?

currently i have re002 on front and bridgestone super cat on rear and i need more grip! 8/6 springs arent helping either

Was good to meet you out there Tas. Is was a shame my new 86 handled like rubbish, but hey, it was it's first ever drive pretty much! haha

At that track, if you have the money ($350 per tyre), Dunlop Direzza 03G MEDIUMS are the Semi slicks most people use...... But in saying that, I set all my records using Federal RSR's.... Some people bag them out because they are not a R compound, but are great at this particular track as they dont need as much heat in them to work rally well.... They are only $120ea too
