Toyo R1R's or R888's?

[FlipFlopGriff]

Looking at a change as I'm fed up with the Dunlops and they don't seem to be wearing. Also had a few wiggles recently in the damp and I want to reduce my potential risk. I know the sizes are an issue and availability also may be a problem but i've got time. Any tried R1R's as they seem to be a happy medium between R888's and T1R's. I do use the car in the wet so not too keen on the R888's but may stick some rears on a spare set of wheels for occassional use - ie drag strip days.

Hi FFG
I'm just about to change to R1Rs at the end of the month. Had a long chat with the tech director of Micheldever at the FoS who said they're not far behind the 888 in terms of performance, but MUCH better in the wet. The Lotus boys also really rate this tyre too. Got a fitted price of £489.60 - 205s F/ 225s R.

Love my 888's to bits, best tyre i've had on the car and awesome on track! Don't really care about standing water issues cause if its raining that hard i doubt i'll be in the car!

I've had R888's on mine come rain or shine (and a bit of snow). They're absolutely fine in the wet, the only time they struggle is with standing water, and in this situation you just use a little caution as you should anyway. Nothing scary about them, you just need to be sensible in the wet. The grip on a normal wet road though on R888's is phenominal, and in the dry, the performance increase over T1-Rs is as big a jump in performance as putting on a supercharger - they're awesome!

How many miles do you get from the R888`s and i wonder how many miles you would get out of the R1R`s

Agree with that.

I did a wet T/D with a griff boy who had T1R's as opposed to my Triple 8's, he was the one spinning

I'd go with the R888's but there is a nagging doubt about their wet weather ability.
Its pretty squirmy now with the Dunlop so I dread to think what it would be like with little tread.

Don't forget the Triple 8's are a softer rubber that work well in the wet, (unless they are very low on tread!).

[Jammy Dodger]

interesting..... I'd pretty much decided on R1Rs for my new improved

R1R not to be confused with T1R

looking at the pattern I figure they MUST be better as all weather dailys than the 888, should last a bit longer too.

I wouldn't worry about life of 888's - I've had mine on for two years, done several track days on them and regularly hang the back out and they're only just starting to look like they'll need changing. When compared to the R1R, they are the same compound - the same tyre in fact, just with a little less cuts in. The only difference you'll see is with standing water. In fact, as the R888 has more soft compound in contact with the ground due to less cuts, I'd imagine that it's marginly better on a wet road than the R1R. The R1R being better in really wet conditions when the channels come into their own. Personally I'd just go R888 and just exercise a bit of caution when it really starts to rain. I've had R888's on my blown chim for a good long time though and I have no issues with it being slippery in the wet, even with a silly amount of power on tap. You just drive to the conditions...

Eann Whalley took me for a 'spin' in his turbo Chimaera a few weeks ago.
It was damp and the rears span up with ease when the boost came in delivering 330bhp @ wheels.

Not as many as I thought...according to the copper last thursday...£60 quid and 3 numpty points for not checking them more regularly

that's on the 888s isn't it ?

and no "speed awareness course" option in these circs. either

I've got to go on one of those instead of 3 points on 22/08 (otherwise i would be on 9)

Your new engine we see a few added I reckon

I did one of these last Wednesday.

Not as bad as it could be, 4 hours with a guy who is an advanced bike and car instructor. It was easy to focus his attention on driving quickly "within the law", quite interesting, (or I am turning into an anorack!).

turning into ? a bit late for that

Hmm....not getting into the debate on which tyre... I'm interested in illegal worn tyres,

last year before I dropped my car at the garage for service and MOT I checked my tyres all round, and they had plenty of tread IMHO. The garage checked them before sending for MOT, and they said they had plenty of tread..... MOT man said

This year took the car myself for MOT, got chatting with the son the of the owner who had a Griff few years ago mentioned my issue with tyres last year so he checked them before I booked in, he said plenty of tread not a problem. The bloke who did the MOT told me to get the tyres changed as they were on the limit.... I've checked them and IMHO they are no where near the limit.

Now this has happened twice, is it a case people don't know exactly what they are looking at when assessing road legal track day tyres .... tyres still on my car, have a look yourselfs when at the growl... I would like your opinions

Steve,
Personally I'd never let a tyre run anywhere near the legal limit and replace at about 3mm as this is when the performance dramatically reduces, ie stopping distance, so if you are close it would be in your best interest to replace them. I guess this ain't gonna happen by the weekend now though so lets have a butchers. Are you on the roling road?
Extract from MIRA report:
"MIRA’s research was carried out on four separate vehicles, a mid range family hatchback, an MPV, executive saloon and a high performance saloon car, measuring stopping distances at 50 mph in conditions that represented moderately heavy rain (0.5mm to 1.5mm water depth). The research discovered that tyres with a 3mm tread had a 25% better performance than those at 1.6mm. In terms of stopping distance this represents an extra 8 metres (25ft) in wet conditions. In one test, when a tyre with a tread depth of 8mm was compared to one with only 1.6mm, the stopping distance increased by 13 metres (42.25ft) - the equivalent to double the length of a typical living room."
Some video footage on Continentals site showing comparison of stopping distance of 3mm and 1.6mm tread:

There is a lot more on the web if you want to search.

Best advice on the thread . .. for whatever road legal tyre you're using.
