Did you recalibrate your speedo for the 305/30/19's?

I get the traction control warning on really hot days, with my pulls up over 100mph. I have 305/30/19's

Not yet...after I get the car retuned with the ported intake and converter I'll have it corrected.

I ran both the BFGs and the Nittos on my 2002 SS and I will agree that the Nittos performed well in DD situations (rain, etc...) where as the BFG had a little more bite but were a nightmare in the rain. Nittos also lasted twice as long and still hooked at the track (at least @ 12psi)

Any oppinions on Nitto's NT05Rs in 345/30/19's? I just bought another set of GS wheels for my car so I could run drags and stockers without dismounting tires everytime.

Good news.

jpee

Seeing that I'm not running a "Hi Horsepower car, I decided to try Nitto Dr (Not the New ones) the old harder compound... I was using MT but after doing a burn out, I found them wearing out too fast for my likeing, AND I didn't really need them...

I am Automatic, & have a stock converter, I only run 12.0x and 60' in 1.8x but I got a FULL racing season out of the Nittos, & I never removed them when I got home.. I just use them 24/7

Right now they are at the wear bars, and I have 2 or 3 races left.. so it will work out perfect...

As soon as the season is over, I'll just get another set of Nitto... Granted they do NOT hook as well as Mickey Thompson, but I don't need MT and get twice the wear out of the Nitto

If I decide to let Cartek have some fun with my hard earned $$ then I'll switch to MT...

this is great news, the r888 im running in back spin almost as much as the stock goodyears, unless the temp is 80 or higher. I've had zero issues with the 305/30/19,and if the new tire is truly 27", i believe its very close to the stock diameter.

The optimum tire that would fit and the covenient tire arent one and the same. The best traction will come from a taller sidewall so a low profile 305/19 will fit a stock rear rim but aside from convenience, it isnt better than a 305/18 for use on a widened front wheel. I dont see why anyone would be still waiting for such a tire for a stock rear fender car at this point. Its 400 to widen twon wheels and its been done so many times that I dont get why this is seen as some break through.

My car is at 959rwhp with these widened wheels and such wheels are as strong as a stock rim.

What it looks like on the car:

If anyone is that put off by sending out a set of 18's to get widened, its got to be some kind of award for laziness. This is especially true if you will be settling for second best traction by using a low profile tire to yet still avoid it.

In any event, I post for the guy who hasnt seen this thread:

Taller tires rotate slower in the rear which doesnt trip traction control. Rotating rears faster in relation to thr front does that as when your rear tires are severly worn or are smaller in relation to the front. Active handling may trigger but there are members who used a 28" tall tire in the rear at the track so it does function.

The Nitto booth was quite beautiful!

The 305's in combination with stock front tires will trigger a "drag control" message on the DIC upon relatively sudden deceleration.

You can upsize your fronts to compensate if you decide to run these all the time.

I cannot correct for this using HP Tuners...perhaps someone smarter than me can. You can change your speedometer reading with HP Tuners but it doesn't seem to correct the drag control message.

When I went to 345's out back I upgraded my fronts to 295's and I have NO active handling issues. You have to maintain close to stock ratio front to hear height.

Spin is correct, the 18" tires are better...bigger sidewall is better for drag strip use. I actually run 315/35/17's for drag strip duty.

Here is a pic of my stock tires vs my current setup. Z06 fenders allow a lot more tire.

I'm considering the NT05's for my GS. They should last longer than the R's?

G8Dave

who has them and how do i get a set..
Thanks ,Dave

Not on their website yet, would love a pair also....

I've got a set of front gumbys at Weldcraft right now. It's 235 per wheel plus shipping both ways. The total will be around $540. Still not too bad though considering it's going to look stock and I should finally be able to hook my measly 515rwhp. Best thing about the 18" is that I can switch over to some R888's if I feel like road racing.

FloydSummerOf68

Widening wheels is a great option, but not necessary if we get the 305/35/19 out. The increased overall diameter and thicker sidewalls will help offset that it's on a 19" wheel and will be more than enough to hook up some pretty serious power.

Instead of spending ~550 bucks to widen the wheels and THEN buy tires I'd just use it to buy tires

Having 18's has it's advantages though, like you said, for switching out to multiple tires because there is greater selection.

The 19" MT should offer superior traction over any of the run-flats/street tires. Spending $540 to widen wheels should be of little concern in the long run though if the car is driven rather than sitting in the garage. The tire treads on the 18" MT's feel so soft they're practically like a gummy bear compared to the stock GS-2's. They look like they'll only be good for 2k-4k miles. At that rate I'll be replacing them every few months. $$$

FloydSummerOf68

Yeah, about 5k is the most you can expect out of MT ET Street Radials.

I daily drove a set on my Fbody for a while

Called Mickey Thompson Technical today.
Per the tech they are coming out with one
19" tire. The 305/35/19 et str radial II
will be 27.5" tall, 11 inches of tread and
12.2" sectional width. I am definitely
concerned about the tire being too tall.
Also I would probably want to widen wheels to
11 inches. I would have been much happier
with a 285 or 295 that came in at 27.0 inches.
oh well.

If it had been 305/30/19, life would have been good. Is tall enough to mess up active handling? The solution would be to match it to a taller front tire, but that is making this investment.

I posted this on the General section. There is a conversation going on now. Summit racing has them available now for $333.35. plus $16 shipping. They won't be shipping till 2/16/11. I think the part number is 3723R. the size is 305-35-19. They will fit the stock rim and its a taller tire. This is a great tire for someone that wants better traction than the stock. I wanted to widen a front wheel also, but its a pain to find a chrome wheel at a reasonable price. I would have to send the repros so they can test the strength. If it fails, thats a wasted rim and a waste in shipping cost.
