The new Toyo R888r shouldn't be operated in temperatures below 15 degree's or they will crack/lose grip but would 40-60 degree weather be ok or should I wait? If anyone has ran the new r888r in cool weather what were your results? 

 

I have a track day coming up on the 14th next month which is why i'm asking. Couldn't find much online.

 

Thanks!

I have driven in 25-40 degree weather with the r888r, however I didn't track them at that temperature. They worked fine for me and they definitely warm up faster than the MPSS I used to have. Good luck with other replies. There's someone on here named AutoxGTR who could definitely help with the tracking question.

They're fine all year round.

 

Will you have ideal grip on the in the dead of winter? Probably not. Can you take the car for a spin without attempting to push Nurnburgring style records on the street? For sure.

 

I daily drove 3 sets of R888 into the ground, through the dead of winter, even on actual snow and tons of times through cold rain.

 

There's lots of opinion given on the tire subject based off second hand research rather than first hand experiences. Take extreme words of caution you might get from some with a heavy grain of salt.

I’m on my third set of R888, never used the R(yet) and they were like ice skates under 35 degrees.

Any R compound tire is not meant to be used for any cold temperature weather. They won't soften up until they reach over 100 degrees so at least warm. On a cold day the ground is cold and the tires loose heat very fast.

 

It is possible to take some easy laps at a track and let the tires warm up then drive with more grip but it's tricky.

 

Any street tire meant for summer use is also not good for any cold weather, for cold you need at least all season tires but the best handling tire class for that is only Ultra High Performance All Seasons.

Thanks for the great info guys! Sounds like r888r are good to go in semi-cool weather but should really take it slow to learn how the tires act on a cool track/road. The weekend i'll be going looks to be in the 60's so hopefully it won't be too bad.

 

If anyone around the tri-state area wants to go it's Watkins Glen Opening next month. Not really a 'track day' but if you get in the 2nd/3rd run with the fast cars it's pretty much hot  laps. Last time i went it was an absolute blast. Beat up on a Ferrari F430 Scuderia, 600hp+ Track built C5 Vette, and a turbo miata lol...the 2010 GTR whooped my ass though (Drove a 300whp Evo X MR) 

 

Next year i'll def be running Ultra High Performance All-Seasons vs. R compound..just want to see what the car can do this year. I'm planning on attending a TON of events in the coming year. TX2k, 1/2 mile, circuit racing etc. Hope to see ya'll there!

I wouldn't drive them in heavy rain or under 40 degrees. They are damn scary in either situation and I've run them on several of my cars in the past.   I'm not even talking about the r888r's, I mean the regular r888's.

Let us know how they do...I'm burning up a set of MPSS to get them off my tire rack at a track event on the 21st then switching to a new set of R888R's until July.

This year reminds me of 2016 it had 28 degrees morning temps in the 3rd week of April,wet and cold.

[Dan_585]

Will definitely report back how they perform in cool temps. These will be going on my daily driver so hoping the rumors/reviews are true that the R888R is better in rain. 

[Ducati955]

im on the fence as well, and i think im heading in r888r direction, i use mine more in better weather but i want them to be safe in the rain as well, or if i feel like taking it out in cooler weather... are they that much better than the mpss? 

and how long will they last just for street driving and occasional spirited driving? I dont even get 4000 miles a year on my gtr.

There is no comparison for Toyo R888R and Michelin Pilot Super Sport, they do different things well.

 

Toyo R888R is a R compound race tire that is meant for track duty or road courses, it's more durable than softer rubber race tires that are better for time attack or one fast lap. As a result it can be driven on the street, limited daily use for low mileage GTRs but is better for warm weather and dry conditions. It won't last long for street use only. It's also not friendly for street use, firm riding, noisy. Limited tire sizes that work with various wheel diameters and widths.

 

Michelin Pilot Super Sport is an excellent daily driver tire with very good handling and performance in dry or wet, lasts longer for treadlife except with severe race alignment (negative front camber), has some durability for limited driving school and track use but it's a street tire and reaches it's limits when pushed especially for more modded GTRs. It's comfortable and quiet for street use. Best application is for a daily driven GTR with very limited performance driving. Tire sizes are much better for various wheel widths and diameters

 

Tire wear has to do with your alignment, style of driving, and how much performance driving you do. A track day and aggressive driving can eat through tires quickly.

thank you... I have new forged 20x10 and 20x12... i wanted to put 285/325

 

I use the gtr some what daily as better weather approaches, usually calm driving and occasional beating.. actually that happens a lot, lol.. at most its 4k miles a year, my commute is short and I have other cars i use.. im fbo e85...

I would like maximum performance for the occasional race here in there but not sure if that matters..
