Kuhmo Ku36 Tyres

[Marlin]

Hey guys, I've purchased a set of these just for track days as I'm a little tired of ripping up O3G's just for messing around.

Has anyone used these and found a good operating hot pressure?

I have a 1270kg R32 GTS-t.

Cheers, Ben.

[hrd-hr30]

hehe... I have

I tried all sorts of pressures, but got my best times at about 36psi cold. They are a street tyre and don't have the construction of a semi slick hence the crazy pressures. That was on my Supra which weighed in at 1640kg with me and half a tank. Benchmark is 1:00:79 mate

I'm looking forward to see how they go compared to the DZ03 to give me an indication of the Supra's potential on proper semis. So far I think the Supra would have been faster than my Sil80 on the same rubber, but hoping to change that this weekend!

I picked up a set yesterday from a Kumho motorsport distributor in Sydney and was having a chat with him.

He advised in the 32 GTR, that i should be running at 38 rear, 40 fronts.

[Marlin]

Piss that in Harry. lol

Nah, I knew you'd used them and was going to hit you up Sunday, but never know if you're telling the truth or not LOL

So treating them like pure rag roadies is the best bet. I'm interested to see how they perform and last on a cost/pace/wear basis. Should be interesting

[nismoman]

I was thinking of doing the same and buying the KU36's for my next set of track tyres.

For the price, it's very tempting.

Does anyone know what they are like after 5 hot laps? Do they go off like a standard street tyre? Or do they hang on a bit better?

[sav man]

do they stand up to track work better than a normal roadie? i've seen plenty of roadie's start to spit out tread blocks, and delamenate after track work.

[Marlin]

Yeah, they seem to hold up ok from what I've already seen and heard mate.

[hrd-hr30]

They copped all the abuse I could throw at them with my, lets say 'excuberant' style, and lard arse Supra on numerous track days at Lakeside, and also at QR, Oran Park GP and Eastern Creek. I had previously torn road tyres to shred on the Supra.

[Noddy]

this will be an interesting thread to follow. We put a set on my bro's wrx and the little street driving I've done in it they feel better than the potensas that were on it. Should get some testing in this weekend on the backroads around mawillimbah.

[spec-V]

Have been running them for nearly 2000km. Hard street driving.

I love them!! and for less than $700 a set they will be my street tire forever (or until the special ends!!)

Still holding well... best results warm them up. about 40psi hot is where i run them for best results. Although mine are heavily stretched and on 4-6 degrees camber. Don't know if that means anything

Keen to see how you go Ben. I'm thinking of grabbing some for the STi as track rubber as the RE070's are too pricey for track work.

They're such a cheap option, and hopefully you like them as that's the sort of money I'd be happy to spend for a few trackdays a year in it.

A few guys were using them on evo X's at winton, they seemed to go off after a few laps, they tried a few different pressures 35-40 and it made no diff. They were used to R888's and RE55's. Id like to know from first hand experience or from a few other guys before i lay down any flap on some (keen to do so).

From what i can gather (all feedback not first hand) they are awesome to use as hipo street tyres but average on the track compared to their FEDERAL 595RS's counterpart.

i just put them on my rears today, i reckon they are pretty good so far

ill let u guys know when i get a chance to properly test them out

[_Ryan_]

235/45/17 on a 17x9

32 GTST, I have found them better the more i put in them, took them out at 34 cold, rubbish, 36 cold, better, 38cold, seems to be about right.

[Bozman1]

I have driven on them many times....tested them for John Mills from Kumho on his M3 at Wakey one day as well

As Harry said, they are not an R compound but are much better than a road tyre.

Best suited for someone that is on a budget or drives a road/track car and cannot be bothered changing tyres lol

If you want to go faster, you need to spend more

If you want to go faster, you need to spend more

Those words ARGH

[Marlin]

Well, did 80klm at Lakeside yesterday on the 235/45/17 KU36's.

Fisrt run I was concerned I'd made a bad decision as the were very slippery, but each subsequent run they got better.

Once I came to the decision to change driving style to suit the tyre it was actually fun.

As opposed to R comp tyres that (IMO) reward smooth and straight driving, the way to drive these was a fair bit looser, and really punish them.

Ended up with a best of 61.20 secs on what was a very hot and quite windy day and the track seemed a little "off" judging by other folk's times.

My best on O3G Dunlops in the same size is 58.63, but that was in kinder conditions.

All in all, I reckon they're superb value, they don't offer the feel of a race tyre but really hammering them made it fun! Not worrying about sliding them because they're so cheap is good too.

I messed around a bit with pressures, and found 45 hot was about on the money.

Everyone I've spoken to rates them much higher than the Federal 595RS. Seems the 595 has a very soft casing construction and even light cars squirm them around a lot. I've driven a GT4 with them on around Lakeside and would agree with that too.

[phunky_monkey]

Trent mentioned the Federal 595 RS' as possibly being better for the track, has anyone had a comparison of the two? They're pretty similarly priced so could also be a cheap alternative if not going for outright times in a championship etc

Edit: Looks like Ben answered my question above, I should hit the reply button quicker
