Performance Tyre talk

[adzy]

What are stickiest tyres you have used? How many KM's did you get out of them and how did they stand up to the temperatures of track work?

Below are some of the tyres which I am currently considering for my next 1500 KM's of abuse, big cornering blocks, stiff sidewalls and lots of un-grooved rubber

Why not base your choice on a tyre review that uses a similar car? Like the EVO tyre review which uses a GTI and has the Goodyear F1 Assymetric as the top tyre and the CSC3 in third place. If you do a search you'll find the results and link to a pdf as well IIRC.

Have used RT615's on my GTI....they lasted 17000k and I didn't treally rate them. Did 2 track days in that, a bit of temp damage on second go.

Currently using Yoki Advan AD08...excellent tyre in dry...a bit dodge in the wet but not dangerous. Done about 10,000k on them and they are still going pretty good...should go close to 20,000 I reckon. Done 1 track day on these so far, handled temps very well, better than Falkens.

Used Pirelli Rosso's and Conti CS2's...both better in the wet but didn't cut the mustard in the dry.

Had a mate who swore by Toyo R1R's but that was on a Nissan GTR, they lasted well and stuck well for him.

Have seen many a road tyre fry on the track badly...Bridgestone RE050's ruined, some dodgy Maxxis absolutely shredded....my advice, if your tracking your car, go R spec tyres, well worth it. Incidentally the semi slick tyres I have owned have been way cheaper than the road tyres.

I've got RE050 adrenalins, hot street tyre and would do "ok" on the track but I doubt they would really "like" the track.

These are more expensive than R888s etc because of the built in compromise.


As Mav said, find that EVO pdf adzy

I am leaning towards the Kumho Ku36 at the moment as I have been on many forums and web sites and rarely find anything less than praise for them. I have been quoted $255 for 225/45/17's which is a pretty good price.

Should be more like $160 per tyre.

That's where I got my 205/45/16 KU31s for $100/crner.

I have a mate with these on a 180fwkw pulsar and they handle well (yes it has the Nismo LSD)

And yeah, you should be able to get them chepaer. Tempe quoted us 190 a corner for R888s..... ( I dontl ike tempe but if they are going to sell the same rubber cheaper, why not...)

Is the same rubber or is it old stock? Or imported from a country like the USA where it has a different compound and is regarded as a winter tyre? Or perhaps it's a cheap Chinese knockoff? Worth looking into before purchase and checking it against a known real one after purchase.

[schoona]

Well yeah they would be my reservations about the place too.
Burgs just got 452s from there. Will check the date on those tyres when i see him next.

When it comes time, I'll be replacing my Pirelli P-Zeros no questions asked.

I've done many a track day and I generally hammer the p*ss out of my car (particularly around corners), they do a great job. had them marbled up to all buggery, but I don't ever recall having them let go on me.

Granted I've not tried anything else, but you have to work hard - really hard - to get them to break in the dry.

In the wet - so so.

I was half considering a set of R specs the next time around (yokies), but I don't think the tradeoff will be worth it.

[gareth_oau]

Ive got the Goodyear Assymetric on my big GT-P and they are a fantastic road tyres, and according to all independent tests (and not my subjective, limited opinion) they are the best tyre out there for overall AND wet weather performance.

but they arent a track tyre.

According the last Motor magazine tyre test, they will crap all over a semi-slick in the wet (as you would expect), so its up to you to determine how important wet weather performance is, overall in your requirements

[kryten2001]

Interesting question though - R specs - Apparently the biggest trade off is noise, as well as heat cycles. They're apparently only rated to be cooled/heated so many times before they lose effectiveness (grip).... In other words, they actually lose grip before the tread runs out - if you run them as daily street tyres.

Comments?

I could live with the noise, if it's not too bad, but losing grip because of the rubber going off after xxx number of heat cycles, compared to regular street tyres, would really bum me out.

That would really suck alright, though it would be hard/impossible to generate the same amount of heat as you would on a track day when driving on the street. I guess all rubber goes off after too many heat cycles its just a matter of how tolerant they are.
Any one used the pilot sport cup's?? Dont think you could go wrong with these things at all!!

[schoona]

If price is no object i think is the motto with them....lol

[John Deere]

I would almost confidently say a heat cycle = a track day.

I dont think my Yoki's heat up on the road to anything like what they do on the track...and 10,000k's and they still grip good.

If you want to go to the track and go better and are willing to put up with small compromises when your not on the track get R specs.

Ideally if you are cashed up and can be arsed, you should have 2 sets of rubber (and wheels), but I am not and I can't so I go with the R specs.

A note on wet performance.....it is pefectly acceptable for everyday driving in the wet and for a little push, but good road tyres are better. I have broken traction in the wet n a straight line at around 80k's an hour with the Yokis (obviously giving it a squirt)...would never have done that in the CSC2 or Pirelli Rosso's. Like Gareth said...you have to assess how important wet grip is to you.....to me, I almost never push in the wet, so its fine.
