Toyo R888R Tires

[Sniper]

I love the look of these tires but the one thing I don’t like is they’re only available in 345/30R19 and not 355/30R19.
Anyone have any input on size, handling, looks, pics compared to stock tires?



Jon, I corrected size in this post

The anticipation is killing me, finish the sentence!!

LOL don’t know why when I saved, it didn’t save whole post...

Certainly -not- viper sizes... Typo ???

I can read your mind: 10mm DON'T MATTER

-5mm inside....-5mm outside. Only YOU and I will know.... dont tell anyone.

If you MUST have the 10mm "size matters in macho" and R-compound, prepare to spend +$450 for CORSA tires set. Expensive 10mm ?? She wont notice.....


Or: go 20mm WIDER on front! Nobody will notice the rears!!!

Assuming you mean 345/30/19 and 355/30/19, the Toyo’s fit as large as the 355/Pirelli’s. If you search the posts I suspect you will find the vast majority agree, these tires are suited well to Viper and are the preferred choice for all the aspects you mention above.

Some people groan about noise and others treadlife....you have to give something up to get something in return.

Notably, The vast majority of people rarely agree on anything - that should be the component to inform the answer you’re looking for.

You bet! I just sent you an email Doug - I’m hoping that I’m actually going to get out this year, May 3rd isn’t far off!

[Tay]

You will not even notice the difference. Do it!

[outnumbered]

Love my Toyo's. The new style is much quieter than the previous.

I don’t know why anyone would want the R888R over the Pirelli Corsas for street driving ’s now that they’re available. The Pirelli’s have no weakness and are really good tires..i have 16,000 miles on my second set and about 3/32-4/32 remaining.. work well in rain, quiet, good grip...

But are $

[Bill Pemberton]

My apologies BluByu but the comment that the Corsas have no weaknesses needs to be modified in one area in my estimation - track usage. Yes, they are a decent street tire , though quite expensive, but many of us have had issues with them on track. They chunk badly , especially on the front, for those really quick drivers, so many prefer other options if they plan to do HPDEs or Time Trials. Now , after saying that , the R888R has potential concerns too, and we probably had more complaints after installing these on Vipers than any other tire I remember --- they are noisy and quite a few individuals found this disturbing. The other situation that can occur , depending on the part of the Country you live in, is that they are absolutely horrible in the rain - downright dangerous. Don't believe me, just check Toyos own notices and also when referring to that, note they recommend this tire for autocross or road course use only.

That leaves ( for Gen III thru Gen V ) a couple of tires I think work great for street driving and even an occasional HPDE for those just looking for a fun time, and they are the Pilot Super Sport and the Pirelli P Zero. The PZero is alot less than a Corsa, rides well, and sheds water fantastic, and was original equipment for most Vipers. The Michelin Pilot Super Sport is an older generation tire, but the compounding is different than in the past ( noted by some friends at the Bibendum Plant ) and they are great in rain, quiet and still stick decent. Don't worry about the 345/19 size as it was what came on Gen IIIs and Gen IVs , anyway -- work fine.

Now call Jon B. and he can get any of them, but more importantly he can listen to you and decide what is the best remedy for where you life, how you drive , and what will match your budget the best also. Good luck!

I've been thinking I would go with the Michelin Sport Cup 2's for my next set. Supposed to be great for both street and track days. I might make it through the summer on the Corsa's, but they are going to be shot at that point. Never had the Toyo's and heard the same negative complaints about the noise and ride quality on the road. the only reason why I would be concerned about the rain is if I somehow got caught out in it as I typically only take mine out when the sun is shining and streets are dry.

[Bill Pemberton]

Have run the Cups myself and they are standard on GT 350s that quite a few friends run. Solid track tire , decent DOT street tire, though it also is a bit compromised in the rain, though not to the degree of the R888rs. Not a bad price for a full set and another good alternative for those who want a pretty serious track and street rubber donut. Would take then over the Corsa and R888r any day.

[13COBRA]

I've tracked on Corsa, R888Rs, Cup 2s and R7s.

Compared to the R7s, the R888Rs weren't horrible in the rain. They do hydroplane, but is somewhat controllable.

As far as an every day tire, I would prefer the P Zeros or the R888Rs. The P Zeros if you're looking for a quiet ride with 70-80% traction on full power... or R888Rs if you're ok with a little extra noise for the extra 10-20% more traction on full power.

If you have aftermarket exhaust, you won't hear the R888Rs anyways.

[sharmut]

Has anyone tried the ACR Khumos on non-acr? Excluding rain, they worked great for me on the ACR for both road and track with 2 defencies. With the factory recommended track alignment, the fronts are done(cored inside) in 3-4 sessions, more aggressive drivers cored after 2 sessions. The rear tire weight considerably more than R7s.

[Bill Pemberton]

The ACR Kumhos are pretty reasonable , but remember you need an 19 inch up front too......so limits the Snakes that could use them.

I used to live in Calgary. Miss it a lot. I still try to get back whenever I can. Sounds like the Viper community in Alberta is really growing.
When I bought my RT new back in 2000, the registry told me it was the 7th Viper in the Province.

[Bruce H.]

I agree with Bill but will point out what causes the Corsa to chunk and how I have avoided that while successfully running out front with the fastest on track for years, ACR-Es and now the GT2RS being obvious exceptions. The front tire edges can be destroyed in short order by going on track under-inflated, heating shocking the tire, and sliding the fronts too much...all of which kills those edges, and some or all of which many drivers tend to do. The trick is to warm them up a bit slower to avoid shocking the tire with some warm-up laps, bleed down pressure as the tire heats up rather than start low and increase to your target hot pressure with increasing heat, and to use a slow in/fast out corner strategy that avoids excessive sliding and overheating of the front tire edges. And if you don't think a skilled driver can be really fast in a Gen V on track without over-sliding the car through corners and killing the tire edges than I think that is beyond the scope of this thread. Also, I'm careful not to expose the tires to cold temps as strictly recommended by Pirelli, and don't know if cold temps can make them more prone to chunking on track in the future.

Corsa is a fantastic streetable tire that will perform great on the track for those that want one set to be really competent for both uses, but you do have to manage them as I describe. If you need a tire for time attack or to get the fastest possible lap time choose something else. Those not willing or able to make accommodations on track should also choose something else...and accept the street compromises that choice involves. I'd use a different tire myself if I were willing to compromise on street use needs.

And if you think you'll find a tire that does both without compromise, well, good luck with that

I ran the 911 Turbo on track last summer starting with the new OEM Pirelli P-Zeros and had to come well off my Viper/Corsa pace in corners (as expected) due to less tire grip. Then I swapped on Michelin Pilot Sport Cup 2 that were obviously much faster than the P-Zeros, but honestly felt about the same as the Corsas in grip and handling characteristics. But where the Corsa retains track grip for me until the front tread is gone, the Sport Cup 2 lost noticeable grip in corners with less use, heat cycling out with a ton of tread still on all tires. So then I could drive slow or replace. I had previously debated trying Sport Cup 2 on the Viper for this year but in the end longevity won out over the last possible 10th in lap time, particularly once decided to make the trip to Miami for the now cancelled NVE and I didn't want to have that contribute to the tire prematurely heat cycling out.

My 2 cents.

[Bill Pemberton]

Will just say if Bruce is getting that kind of wear out of a Corsa the rumors have to be true that he is not only fast, he is also smooth, ha!!!

That is good info Sir! I tend to be kind on my tires as well and have been very happy with the Corsa's on the street for spirited drives. Haven't tracked my '16 yet and basically was going to just try to figure things out as I go. Smooth is fast in most cases as you pointed out. Surprised the Sport Cup 2's didn't last as long as you had hoped.

[Bruce H.]

I am smooth but really aggressive in the brake zones, braking hard but for a brief period, partially because that tends to keep more heat in the rotors and less transfer to the calipers and fluid, but also to manage the tires better on entry and through mid-corner. Works well for lapping days.

I did forget to mention the impact of track pavement on tires, which is brutally coarse and hard on tires at some tracks and easy on others. Three track buddies each chunked good left side tires in one day at one particular track (brand new Corsa on my TA, brand new MPSS on a C7Z51, and MPSC2 on 911 GT3) while another in an BMW gutted E30 race car showed minimal wear on his used Nitto NT01s. That factor would definitely impact results of different tires.

[sharmut]

It's not a surprise to hear the CUP-2s heat cycle out sooner than one would expect. A fellow track buddy mentioned the same results on his relatively stock C7 Z06.

A track buddy with an AMG GTS heat cycled out his factory MPSC2 half way through the 3rd track day and just parked it, said car was too dangerous to drive. Another time he had Dunlop Sport Maxx R-compounds on it with some track days and when I took it out, he warned me first, and the back end was so loose it was very unnerving. Never had either experience in the Viper on Corsas even when worn down to the wear bars.

Bill, thank you!
Tried to send you a pm back but seems like every time I post on this forum, it cuts 90% of my post out when I publish it.



I am not concerned about driving in rain or the little louder noise. I don’t track my car.
TBH, I am sold on the looks of this tire and the performance on dry pavement is a bonus
