I now have some K on my TR1's, come to think about it I have no idea how many, but!

First track day, they had about 200k's on them, found them a bit squishy, but got that under control by reducing pressure, high 17's.

Second track day, maybe a couple of thousand K's, far better, but still with lower pressures, very low 17's

As for on the road, my best comparison is GPSS, those who know it, will get this. They are pretty close to DJ01's, R888's, RA1's at 5am. I love 'em, by far the best road rubber I have fitted to an MX!!

CB, I am sure you will find the GROOVE, and when you do :mrgreen:

Well the jury is still out on these tyres after a very hot day at Wakefield. Everyone was slower than their best times by between 1 & 2 seconds, with the NC at the 2 second mark. So I really can’t tell yet if they match the Michelin Precedas.

What I did notice was that the tyres were very predictable once the car was turning in the corner. By that I mean that you turn the wheel and then ..........wait........ for them to respond. No instant turn in on these puppies. You need to adjust your driving to suit. Set the car for the corner, turn before you normally would so by the time the tyre reacts you are on the right line for the corner. Once there they hung on well, were predictable and allowed good adjustment mid corner if required.

On the hill climb section that has a lot of 1 & 2nd gear work and on the main circuit onto the straight, there was a lot of wheel spin out of the corners, even with the LSD. So getting the power down and drive out of the corner was a problem as I needed to feather the throttle to get them to grip.

So there you have it. Due to the hot conditions it wasn’t a fair comparison but two seconds is a long way to make up around Wakefield.

For the road however they are fine. You still notice the turn in problem but obviously it isn’t quite as critical as when you are driving at 10/10ths.

For the NC owners I think that I would stick to the Michelins as they match the suspension better than the T1-Rs, but that’s just my opinion.

Hmmm - I've got a good 25000ks on mine now, and have to say they are much better than the P-Zero Neros all through their life. I haven't had them on the track, however they are very progressive and seem to get better with age (and of course a lower tread profile). Not sure why you would have traction troubles CB - give them time is all I can say.
They handle the 160+ kWs my car is making admirably, and I definitely have better \"launch capability\" because of them... just give them time. (Of course I haven't had the Miche's on to compare them too - they may just be in a class of their own... maybe next time if the price difference isn't too great!) :wink:

As with CB, 1.5 seconds behind my best times at Wakefield on a pretty testing day.

But for the road, these tyres are sensational, very predictable, turn in is a tad slow, but you can easily adjust to this and it is a very minor sacrafice for the grip levels you will experience. And at the very edge of the fun curve, you will get a tap on the hands.

Excellent wet grip levels.

Very few $$$

= Exceptional value.

As with all things, enjoy within you capabilities.
