anyone tried the R88R yet

[jesfirth]

as it says. any feedback yet? comparison with R888GG, grip levels wet and dry, how fast do they heat up. how long before they go off?

The R888R uses the same "GG" compound.. suspect it's better in proper wet conditions.

Thanks that's what I thought would be the case but I spoke to the technical director at Toyo last week and he reckons the R has a new compound and more grip albeit still badged as GG (medium). Toyo are not offering them in GGG (soft) or SG (super soft) though. I am interested in real life experience of them if anyone has tried a set.

If toyo are right quite a bit more grip

I will be interested to hear about your experience with them. I also have a set coming but not until May/June. I am going to start the season on my part worn R888's until they are life expired.

30 is interesting. did you run R888's at that sort of pressure as well? I run my old 888's at 21 but I guess my griffith at 980kg is lighter than a cupra? I will be interested to see if the R888R's need more pressure.

blimey 21 is low for a hot setting , I aim for 26 hot on GG compound on 888's.

Thanks Perry - that's interesting. I should probably try back to back tests between say 21 and 26 on a TD and see what my data logger comes up with.

Bear in mind I sprint so we go out on stone cold tyres - so that what the 21 represents. As a sprint is max 100 seconds they never get really hot - well maybe they do at Goodwood but not many other places.

thanks much appreciated. will try a higher pressure in practice at the next event

I have a new set of R888R's for the sprint at Prescott on the 28th. Will be interesting to see how they perform.
