Andrew, I have a set of R888Rs in 13" (my track set) and a set of Rainsports in 14" (my road set) you are welcome to try them anytime. The overall diameter is the same on each set and only slightly less than your 15" setup - although I am in the Peak District so maybe after a blat if you have time (a couple of miles from Yondermann's!). I actually prefer the Rainsports for road - mostly because they are super comfy, a bit more playful and don't shower my car and the one behind with stones that stick to the R888Rs. I realise I am in the minority here but I actually don't want the car to feel like it is on rails on the road.

Hmmm Yonderman's, where we all did sit and laugh about my failure to make a corner and my disappearance up a side road that just happened to make an escape lane ... which was one of the incidents which led to this thread! Thanks for the offer but I guess the wheel size and profile difference will affect things quite a bit, I'll probably just get one to check fit and then give them a try.

Concur with Jonathan, but cant help unless you can visit Australia to pick up :)

Wearwise I reckon hard track days 1 x month for 2 years and going on current rate of KMS about 15000 kms = time for new.

It is very much sticky+ soft = wear, but I am fine with the outlay to A keep me glued down, B. have huge fun on track.

Over here fourwheel drivers rave over Cooper tyres warranted to some colossal mileage, massive deep tread blocks and I think the rubber compound actually has more wear resistance than granite, thank heavens they wont fit a 7! Horses for courses.

A bit of feedback ...

Finally got myself sorted with R888R 195/50 R15 82Vs.

While changing the tyres I got the wheels refurbished at City Powder Coaters in Birmingham. They did a good job for £45 a wheel on a same day service, dropped them off at 08:30 and collected 16:30 with the new tyres fitted and balanced. Would only have been £35 for a 1 week service.

First trip out on the new tyres wasn't ideal; headed off to the local club meet, it rained most of the way there and absolutely threw it down on the way home, with plenty of standing water and then a joker decided to test my brakes by missing his right turn and slamming his brakes on hard, leaving me with effectively an emergency stop, first time out on semi-slicks in the wet.

I have to say ... The R888Rs gripped better in the wet than my T1Rs did in the dry!

Today I've had chance to take them out in the dry and find the limits. I can still lock them up if I try hard enough, but the braking grip available is way beyond what I'm used to. They feel a lot safer. They seem to be able to stop in a few car lengths and they tear up the road surface before they lock. Not that I intend to drive like that on a regular basis!

The other thing that surprised me is that intuitively I imagined that sticky rubber would mean heavier steering; they actually feel noticeably lighter than the old tyres, especially in low speed turning (and yes, I did let the pressure down to something sensible after I got them back from the refurbishers!).

Before the T1Rs I had their sticky cousins, the R1Rs. I couldn't get on with them, they were always tramlining and pulling side to side as though they were running on the sidewalls. I was a bit nervous that these might feel the same, but there's none of that behaviour at all. They feel really nice, light and accurate.

So thanks for the advice. Looks like I'm sorted and happy with the choice so far.

Andrew, how is the fit under the cycle wings compared to the ZZS?

Hi John, I haven't tried ZZS. I had R1R then for the last few years T1R. The fit of the R888R is pretty much identical to the T1R (both Toyo, both 195/50 R15 82V). I can get my fingers in to the knuckles between the tyre and the edge of the wing all the way around, and between the tyre and the wing stays on the inside on both. That's about as scientific as my measurements for I'm afraid!

Seems to be plenty of clearance and today I put about 60 miles on them in the dry. They feel good.

Thanks, Andrew.  Don't know where I got the idea you had ZZS!
