Thanks to JonB, a new world record!!

[Dajerseyviper]

I stopped posting on here cause I simply dont like the moderation staff, leadership and atmosphere, but just wanted to share my super positive experiences with JonB. Afted spinning my car off the road into a grass median after doing a 720* spin on the highway due to hockey puck, dry rotted tires with date codes of 2008 and 2009, I ordered a set of Toyo R888's from JonB. I opted for the 295 up front, and he was $40 cheaper delivered than tire rack BUT, the tires were delivered to my installer in world record time...23 hours and 30 minutes from the time of order..That is unheard of!!!

just figured I would share my experiences!!! Cant wait to pick up the car from the install shop.. I have driven the R888's on a 550hp TT car in the past and loved them, Im sure they are great on the viper!

295/30-18 R888? Any rubbing at full lock? What's on the rear?

[dave6666]

I run 295 on an 11" wide wheel on the front and don't rub.

[stuntman]

Does a 295/30-18 fit on a factory 18x10 without rubbing?

[Dajerseyviper]

Does a 295/30-18 fit on a factory 18x10 without rubbing?

Why wouldnt it? I have the 335/30/18 on the rears. Havent gotten the car back yet to test out.

[JonB ~ PartsRack]

Thanks Rat !Many Viper owners choose 295, 305, or even 315 fronts. I have run 315 fronts since 1994, on 17" or 18" fronts. Secret Weapon.[After 22 years of Vipering, 'Would JonB Sell a tire that wont fit?!" ]

[stuntman]

Jon, so I take it the 295/30-18 fits on a factory 18x10 since you sell them? Does a 295/35-18 fit on an 18x10 on a gen 2 without rubbing or having issues opening the hood with the wheels straight?

I believe that is what the man just said.

Toyo's and Nitto's run smaller than say a Michelin. 295 is more like a 275...

[stuntman]

I believe that is what the man just said.

The question is if 295/35-18 fits without rubbing/opening the hood (on the 18x10) since 295/30-18 is a lower profile/diameter than the factory 275/35-18.

Jon didn't answer my question 3 months ago in this thread either

A lot of people seem to throw widths around without specifying the aspect ratio -which is huge determining factor of the tire's size.

In my experience, R888s run pretty wide.

We have compared them side by side and measured them. Trust me they are noticeably smaller mounted on the same width rim.

295.

30.

19.

11 x 19.

Does not rub.

Done.

I'm considering these tires. I've been reading up on them a bit. Where did you end up getting them installed? I'm not far from you and may do the same thing and order from JonB of course. I'd just be looking to do R888's in whatever tire sizes would work best on stock Gen II wheels. I may lower the car in the future as well so I guess it'd be best to get stock sizes?

[JonB ~ PartsRack]

YES and YES. Even on most lowered cars.

Thanks Octo: Even G2s lowered with springs or caps, or coilovers, a 295-30-18 front is NOT too wide in the R888.

Your experience with R888s is perhaps not as extensive as others.

You can choose R888s in 275-35 or 295-30- 18 with NO fear of rubbing........I would not recomend a 295-35-18 because it is too tall vs OE, not because it is wider than OE.......

[stuntman]

I appreciate the help, but i'm quite familiar with R888s having run them before they were in production as well as on over 15 track cars. I'm not sure what to make of your findings when:

(section width - tread widths):

Front: 18x10

275/35-18 PS2 "C1" = 10.9" - NA (probably a 10")
275/35-18 PSS = 10.9" - 10"
275/35-18 R888 = 11" - 10.4"
285/30-18 R888 - 11.3" - 10.8"
285/35-18 PS2 - 11.4" - 10.6"
285/35-18 PSS - 11.4" - 10.2"
295/30-18 PS2 (there are 3 different Porsche sizes) - 11.9" - NA/11.5"
295/30-18 Corsa System - 11.9" - 10.8"
295/30-18 R888 - 11.8" - 11.2"
295/35-18 PSS - 11.9" - 10.8"


Rear 19x13 & 20x13:

345/30-19 PSS - 13.8" - 13"
345/30-19 R888 - 13.8" - 12.5"
345/35-19 Corsa System - 13.6" - NA
355/30-19 Corsa System - 14.2" - 13.5"
335/30-20 PSS - 13.5" - 13"
335/30-20 Corsa System - 13.8" - 13.1"
345/30-20 PSS - 14" - 12.7" (seems odd)
345/30-20 Corsa System - 13.8" - 11.2" (seems odd for the tread width, maybe typo and should be 13.2"?, or maybe not from the PSS above)

YES and YES. Even on most lowered cars.

Thank you!

I'm very familiar with them (read above).

You seem to be contradicting yourself a little (post #14). Given the dimensions (above), the 295/35-18 R888 is very similar in section width, tread width, and outer diameter as a 295/35-18 PSS.

So would you still recommend a 295/35-18 on the front of a Gen 2 using a 18x10?

Excuuuusee Meeee! Sorry I did not return to see that thread's final TWO posts! I also missed pastohio's ?? about Nitrogen fill.

To elaborate, the general rule of thumb with oversizing is called a ''Plus 1 = Minus 1.'' [Or +2/-2 etc etc,] where tread witdh and sidewall ratios are the 2 variables. This is why a 295-35-18 is too tall vs a 275-35-18 OE, but a 295-30-18 is generally OK. The only Gen 1-2 'Hood Opening' issues are on the +3/-2 fitments with 20" fronts/rears, or 19" fronts with too-tall sidewall such as -35 series.

If its any consolation, I did answer about 15,000 other questions since 1994! You could always post important or neglected questions here, it seems to be a hoppin' place:

You are saying that 295/35-18 is too tall on an 18x10 for the front of a Gen 2. There are some people running around with that setup but I was a little unsure on it's fitment. It's unfortunate that Michelin does not make a PSS in a 295/30-18

I appreciate the time/help.

Now you are saying that 295/35-19 is too tall.


So does that mean that a 295/30-19 (like Dave runs) works?

FYI:

295/30-19 has a 26" OD
295/35-18 has a 26.1" OD

'Are you still beating your wife' ? "Still Recommend" ?

I did not 'recommend' that fitment at all, and I simply missed your earlier question about it. I suggest 295-30-18.

Im running a 295/30/18, fits perfect looks better than the BFG 275 which looked "stretched" a little on the front OEM wheels. The feel with the bigger tires up front really tightens up the steering and makes it feel a bit heavier if that makes sense.. Traction is SICKENING GOOD!!!! hell yeah, no more wheel hop..

Dude, give it a rest...295/30 fits and Im sure a 295/35 would fit on a stock rim.
