so which tyres do you guys think are the best? say under $280 / corner (16inch)? for track and/ or road use? (when saying the best, I may think of grip on dry/ wet and whether it will last long, but not considering the comfort or noise level)

That's probably the ultimate question for tyres really isn't it? :P

/me sits and waits for a reply.

Thanks gang - the thread really took off :shock: . They have to be similar to the C-Drives I hope. And much, much better than the Marshalls (I know, I know) that are on the rear. At $167 per corner, that's pretty fair I reckon so I will give them a go and see what happens.

Yeah, was thinking about C drives when I was looking for rubber. I don't think I found anyone near where I worked that stocked them, so went for the Kumho's instead. Would be interesting to see how they compare.

You have opened a COW with that comment. :roll:

Most know that I think that the Michelin P2s are the ants’ pants for road and club track work and that Toyo T1-Rs just aren’t up to it.

Funny that one un-named Club member at Wakefield now agrees with me as his times were 2 seconds a lap slower with the T1-Rs on his NB8C.

Ain't that the truth.

Saw this thread the other day so thought I would have a look at the Kumho product. Bought a set of Ecsta SPT KU31's today.

I have run Toyos, Yokies, Michies, Bridgies, and I think Pirellies street tyres on the track, to be honest, they are not made for it, you will live on the edge and grab a hot lap here or there, in between ploughing the paddock. I don't like to Plough paddock's!

If you want track tyres then buy type R product, you will improve your times and be better off for it. But, you will have to compete with cars that have a lot more than tyres to make them go fast in club events. So now the question is What is the best Type R product for an MX-5????

KU31's in a 195/50/15 cost $100 a corner, a full $15 a corner less than the Toyo T1R's, and I will bet around $50 plus a corner less than plenty of others. $100 is cheap as, I mean really cheap :shock: :D

As for times on the track, we will see next club day.

Track days rip the guts out of street rubber, so I expect that the KU31's will be crap in no time at all, but they won't have cost that much at all, and that is a good thing!!!

CB, I think you need to get over the T1R thing, cause I think they even passed you on their way to hell.

$100 a corner, that is very seriously cheap!!!

Hi CT,
If you call a crawl from Tempe to Penrith on the M4 in peak hour a test, here is my opinion.

Very quiet, but then again I only got up to 60 so you would expect that.

I have plans for a little run in time on the weekend, starting with my local test track GPSS.

Will let you know.

Just the paper :lol:

I did a run up the Putty on Monday in the TDI, the storms certainly made a bit of a mess, trees over the road, rock walls collapsed, and the creek that runs beside the last bit was a raging torrent.

But, the road works have been finished and the road is beautifull, a work of art, best enjoyed in the cool air of the early morning, with a little fire in your eyes.

That's good to know. How were your lap times compared with other tyres?

Uhh, is that good or bad? Relative measures are all well and good when we know what we're measuring against, but I have no idea
(a) what makes a good lap time
(b) how those RT615s rate in the tyre quality scale
