Toyo R888R Tires

[ViperTim]

Clarifying: Anyone running "R888" tires, these were discontinued some years ago, so your tires are OLD.

The newer technology is the R888R, the topic of this thread..... Tire debuted in Viper sizes in mid 2018 as I recall....

If you get caught in a downpour, with ponding/puddling, or wet snow-tire ruts, SLOW DOWN. You would likely do this on Michelins or Pirellis. Ironic that in competition events, the R888 / R is considered a RAIN TIRE vs a tru race slick. Good drivers wont pucker.

Might be old but they still hook like crazy. On my 3rd summer now with them.

I have 5000 miles on my R888R tires. Caught in a HEAVY rainstorm last fall for 50 miles. Could hardly see the car in front of me at times and had to pull over. I drove slow with flashers on. Felt pretty slippery but I was careful and got home fine. The grip is fantastic in dry weather. As for noise, on some roads, especially concrete expressways, they have a drone that can annoy some folks but on most roads I never hear them at all. Bottom line: I will buy them again. Great tire!

What sizes did you go with, and what wheels are they going on?

I'm debating tires, specifically the fronts. I've got 18x11 wheels up front (that I also need to have powder coated), and I'm torn between the 295/30/18 and 315/30/18 in the R888R.

I think you're only legally permitted to drive with your flashers on if you're alerting other drivers of a vehicle issue. Be careful, I have known a few people who have been pulled over and issued a ticket for doing the same.

[Bill W]

Thanks for the tip. I'll bet there are more than a few who don't know about this. I was in North Carolina at the time, and it's legal there (last time I checked).

It varies state to state. I got a warning from a sheriff in FL because I had mine on and I was driving through my development. I had stopped to pick up debris with my truck after the hurricane and I had them on when I went by a him. He just warned me not to go on the highway with them on. He was decent about it and I had only driven about 30 feet so just had not turned them off yet.

It's Florida so, um, yeah. Haha

I would think having tire issues would qualify as having vehicle issues.

So I can flashy lights if my heated seats are not working either. Got it. Haha

Obviously your heated seats wouldn't effect your ability to operate your car safely. Running tires not designed for rain would. Like duh. You got it now?

Steve M I went with the 315's up front on the stock sidewinders 10.5". they are badass! r888r's. it's like a go cart!

I went with 295/30R18 and 345/30R19 and wheels are Sidwinder 2s

315/30/18 (in older r888 spec) were bulgy on SW2 wheels extending beyond the front fender. However 295/30/18 r888 tires fit perfectly on my old Forgeline wheels which were a full inch wider than the SW2 wheels.

[parabs]

315/30/18 fit well on my 12 inch wide GTD1 Forgelines:

Looks like the 295 is the right choice for me...I'll just have to lower the front to make up for the smaller diameter tire.

Gen 5 SWIIs have a different offset that Gen 3/4 wheels (the pictures you post are of a Gen 3/4 car). Actually I was under the impression that the different offset would push the wheels further inboard. Maybe I'm wrong though.

Negative...the Gen 5 wheels most definitely go toward the outside on a Gen 3/4 car.

It isn't quite as apparent with Gen 5 wheels on a Gen 3/4, but it becomes pretty darn obvious when you see someone running Gen 3/4 wheels on a Gen 5. Take, for example, this picture posted by TheMadMachinist in this thread:

https://driveviper.com/forums/thread...l=1#post408175



Although hard to tell, those appear to be the Gen 3 10-spoke wheels. The rears are fine, but the front wheels look sunken in due to the offset.

Yup, you're correct. I got that confused. Gen 4 wheels on a Gen 5 definitely tuck in more. I have a friend that ran Gen 4 wheels and it was obvious they were to far in.

I can comment on the noise of these tires as I've drove them for awhile now.
I can not hear them when driving and I have stock exhaust.
The only time I hear them is when I take car out of gear when I'm coming to a stop on highway and they do have the sound of mud tires on a truck but not that loud.

[CNU_Physics]

Yeah the noise they make is really overblown on how bad it is. It can easily be ignored.

[No hemi]

I kinda like the noise, I feel like a jet on a runway

No More Understeer! Instant response.

The diff between 295 and 315 fronts is Night Vs Day....on different planets.

But 315 will spray/splash your door/sill flanks a lot more
