Advice on Tyres

[boon]

$122 each at 235/45R17 - I'll probably give them a hoon next time I need tyres.

I got KH16's 215/40(or 45 cant quite remember this late)/17 and aside from being noisy so far have been a good tyre- except weird as degrading on the left front wheel the outer edges of each tread strip. at first assumes was just guard rub; but it goes in to at least half way and only on the outer edges.

Anywho; paid 125 a corner fitted and balanced. do the job.

Kinda interested in the KU31 as well. $199/corner in 245/45R17

ku31 is the same as the zetums they just made in a different factory

I feel like these zetum things there has to be *some* kind of catch, is it genuinely a good, super cheap tyre but with poos marketing?

Guess that counts for a lot... Those achilles things used to be the super budget brand, sponsor a few drift cars and now they're desireable

Need to get yoself some sponsorship Jase

Achilles are **** but always been marketed at higher of the cheaper end tyres not like triangle/goodride etc. In the wet theyre like an RC car when you pull the rubber off the plastic rims to do skids.

Hi marky..I to was a bit apprehensive of this brand but after doing a bit of research decided to give them a try..I have done about 5000ks on them and have had no issues with them on the road..Can push on through the twistes with 100% confidence..

Tried them at manfeild playday and they grip fine for 4 to 5 laps before they go squishy..Much the same result as most deep tread road tyres..

Can't find any problems so far..

Value for money is excellent..

Dairusire;

I had RE01R too (a tyre no current road BS can match).

In road tyres the only realistic (affordable) choice is the Nitto NT05.

Superb in the dry and not as bad as you think in the wet.

Good value too, last time I looked they were less than the over-rate RE002

Soooo so so true. The RE01R was just a unbelievably good tire and I loved it.

I've now however gone to the Falken RT615K and HOLY SH!T they are GREAT. Nice stiff sidewall, Really good feel even when mildly warm, and when they are hot.... lets just say they stick like a pig to mud

$100 a corner or thereabouts for the coupe, $140 or something for the Legacy. Kindly fitted by Neil. What are your Federals worth?

Yeah i was paying about the same including shipping from Auckland for the E30, but that's just piddly 15s, not sure what 17s would be worth. I wouldn't say the Federals are the best, but as a compromise between grip and life they have done well so far. I think I have only done 2 track days on them though. And it would be fair to say that I am not overly kind to tyres.

As I understand it, Bob Jane tyres in Australia did a deal with Kumho to manufacture the KU31 (or whichever model it is) under licence with a different name. The catch is, you can't ring up Kumho and complain if you don't like them.

The zu37 are made in China as opposed to the ku37 being made in Taiwan I think. Kuhmo didn't want a bad wrap so made a new tyre brand to test out China quality control in case it was ****. Turns out it wasnt

Zetum ZU37. The ChCh guys spotted these. I just switched our BP5 GTB (225/40/18) after competing on them in numerous street sprints and autocrosses this year, wet and dry, in the coupe. I fail to see a better value tyre on the market currently. That said, you can certainly spend up to three times as much (RE050A etc) and get perhaps a scientifically measurable improvement in grip under certain conditions along with terrible tread wear.

Thanks for the advice, will look them up in auckland

Neil said that the compounds were different between the kumho and zentums... the zentums are made from a lower grade silicone or something.

They definitely seem to work pretty well at Port Rd and autox for you though... although, if you were to put some more widely proven

tyres on you may suddenly bust out an 87 second run and realise that the zentums are rubbish

Definitely not claiming some sort of magical semi slick capability. Just a good value, surprisingly grippy, hardwearing, super mild mannered tyre.

If I could pull out ~5 seconds over a couple of kilometres on tyres alone, I'd be laughing =]
