As of right now I have around 450rwhp. I have crappy continental tires that don't give me any traction. I can't decide between these two tires.

Will the INVOs be enough for my power level? The R888s I would be able to get come in 255/35 295/30 would these look and work fine with the stock wheel sizes?

The INVOs come in stock sizes and are cheaper so I am kinda leaning towards them. I don't go to the track just some spirited street driving. I just want to get the most out of the power I am putting down.

Can someone point me in the right direction?

chsmith112

Anyone?

TrenAman

both are good, not sure you can pick one or the other IMO

chsmith112

So the R888s will be fine with those sizes? Will the traction control want to come on because of the differences from the stock sizes?

I've read Toyo and Nitto are one company. The Nitto 555 are basically the same as the R888. Invos I've read are more of a good daily driver tire. My car is being returned to stock to trade for a new Z. I was also at 450/405 and the Z06 tires wouldn't hold. I don't track the car but drive as you do, and was on the verge of getting the Toyo's when I decided to trade.(Reason for trading, my rearend went out for the third time in 1 year. 2 410's and 1 390.) I personally liked the R888, should give super traction and will fit on stock rims. Hope this helps. Have a good day.

The overall tire size of the R888 is almost the same as stock and will not interfer with active handling. You can search the Toyo website for the numbers and compare.Found my sheet, the tire sizes I was looking at were 265/35/18 and 305/30/19. My statement above reflects these sizes. Check thier website for the ones your looking at.BTW my wheels are LG world challenge chromes in 10x18 and 11x19.

Does it matter how long the tires last? maybe that should help with your decision....

chsmith112

Thanks dude!!! I am looking into the toyos more and more. Nitto 555s are they r compound?

chsmith112

A little bit but not too much. As long as they last for a year I would be fine. I don't track it and it doesn't harldy ever rain here.

Invos will not hold your power level in first gear and will probably not fully hold second gear. Tons of posts testify to that. Put "Invo" in the search and you'll get a lot of reviews. R888s will have much more stick in warm weather but you'll wear through them in about 10k depending your driving style and need for rain safety.

Right now I have Continental Sport 2s which I got when I bought the wheels. They are not that great as far as performance. I wonder how much improvment the invos would be compared to those. Anyone have any expierence?

BOB EAGAN

Yes they are R compound but don't come in 19 ". Guys here use 18" wheels. I've been told the R888's are good for 8,000 miles.

i had a very hard time selecting tires last time around also. i was not very concerned with how long they would last but wanted a really good quality tire (one that would balance well. there are tons of posts on tire vibrations), lots of traction and a tire that would be good in the rain. (rains all the time in georgia). Invo's were high on my list but finally went with the Michelin PS2's. (non run flats)

i am not sure what gear you are running but you and i are making about the same power. i have a 3.90 and can not get good traction in 1st or
2nd even when it is HOT out. mind you i am not complaining. i think that is a great problem to have . overall i have to say i am extremely pleased with the PS2's and will buy another set when these wear out. i may just up the size from 285's /245's to 305's /275's.

if your car is lowered you may also want to look at the overall height of the tire you are getting compared to what you have now. they can vary by 1/4 inch or so which does not seem like much. however if you have your car lowered and like it exactly where it is now a 1/4 can make a difference.

If you arent happy with conti 2s you probably wont be satisfied with invos. Get the R888, especially since it doest rain much out there

chsmith112

Will the tire height look the same with the 255/35 395/30 as stock? I am thinking it will be pretty close since it is a wider tire which may make it look a little taller.....or am i completely wrong on this?

ETW

Stock 285 goodyears are 26.9" tall. 295 R888s are 26" tall. 305 R888s will also work on stock wheels and they are 26.5" tall

chsmith112

Will the 305 effect my handling in a negative way?

chsmith112

??????

BOB EAGAN

Don't know about road racing, for for straight line my 275 fronts and 325 rears handle great, after all they are the stock Z06 tires and I think the are stock on the 2010 C6 GS.

chsmith112

so the fact that the 305s recommend at least a 10.5" wheel doesn't effect the handling?
