Looking to change my tires.....I'm at 450whp and have more room to crank up my boost to bump hp to 500+whp.

I tried the R888 but they are super noisy and very short life. RE11 is not available in my country.....I need street tires with reasonable price.....what do you guys think of Nitto Invo 305/30/19 ? If I go with that size in rear which size shall I use in front to match?

 

id go 265/30/19. not an extreme stagger and almost a perfect diameter match so as not to throw vdc off. Also if you want sticky tires, theyll always have a short lifespan. its a sacrifice; grip for tire life. cant have both.

Also pretty sure this is posted in the wrong section and should be in wheels/tires not FI.

 

Michelin pilot super sport if you want street tires. Supra guys love them.

 

Tires aren't magic, upping the tire size isn't gonna magically increase grip. learning to launch helps ease getting power to the ground.

What is your current tire setup first off?

 

I think this where you want to look. expensive though

 

+1 for the Michelin Pilot Super Sport if you want a relatively quiet street tire that performs very well. Tirerack.com ranks it #1 in the max performance summer category.

I have Pilot Super Sports on my DD 370Z and I love them. Much better than the OE Bridgestone RE050A tires. FYI... The Nitto Invo is an ultra high performance summer tire, which is a category step down from the max performance summer tires.

As for your front sizing question... I have 305/30-19 on the rear of my G35 and 255/35-19 on the front. The diameter is within specs for the VDC and this setup worked well for me on a road course track.

 

r888 are far better than the pilot super sports.

i run Nitto 555RII with good results.

 

Of course the R888 has better grip. But the OP indicated that they were too noisy and that the tread life was too short for his liking. So if the OP wants a more "civil" street tire, the PilotSuper Sport would be a good choice (and a superior choice to the Nitto Invo he's considering).

 

PilotSport tires are $420 each in my country so it's out of the equation.

Would the 255/35/19 or 265/30/19 be a better match for the rear 305/30/19 ?

Btw my wheels setup is 9.5/10.5

 

305/30-19 a hankook RS3 , is going to be one of the best tires you can get for a combo of wear vs traction. The Invo is a great tire, but you will easily blow them off with your power.

 

Have you checked with Sub-Zero or Alpha Logic?

 

Way over priced in local tuning shops.

 

barely OT .......

I'm in the same rwhp area and need to decide on wheels/tires.

At what point do you guys think widening up the front width of wheels/tires has too much of a negative effect on handling? emailed Ravspec and asked and was just referred to 370Zs running 11" rears and 10' fronts (I think)

I was thinking of going 19" x 11" on back. prob not much difference between 9.5 or 10" on fronts depending on what wheel sizes are available from manufacturer, eh?

sort for Semi-thread jack

Then your thread title should be changed to "FI and tires... the hunt for CHEAP and QUIET traction with long tread life".

You can't have it all. You have to compromise in one aspect or another in this case. BEST TRACTION, QUIET RIDE, LONG TREAD LIFE, or CHEAP. <--- Pick 2.

 

Can't wait to test out my re-11

 

Regarding 255/35-19 vs 265/30-19 on the front wheels in combo with 305/30-19 at the rear... 255/35-19 is the same or within .1" of the overall diameter of the OE front tire fitment (26.1"). The 265/30-19 is signicantly shorter (25.3") and could cause VDC issues.

 

As I said in my first post I'm looking for 'reasonable' tires that can fit the budget not the cheapest. I do understand that there is a compromise. Let's put it this way, I'm certain that I will be going with Nitto Invos as I tried them on my Z06 and they did the job at 580hp.

My next question is which size to go in front to match the 305/30/19 rears?

 

^^ I answered your question about the front sizes.

 

Sorry I skipped your post....thanks for the info

 

You know it is the percentage from front to rear , not from aftermarket to OEM that is important right? 265/30 would actually be a better choice do to the 305/30 being shorter than OEM too.
