Hi guys,

My stock P-Zeros are not dead after 7200 miles, but they are about 35-40% worn and I'm wanting to replace them in the near future.

First, with a 1 inch drop planned before so, what is the largest size tire I could go with on the brembos all the way around? (Width and sidewalls on 19X9 brembo rims) I am NOT a fan of super low profile tires.

The rear tires on this Stillen Mustang are about what I'm looking for as far as sidewall/width ratio goes...I just cant seem to find what size tires these are. any ideas?

 

That looks like at least a 305 width which is going to be far too wide for an our Brembo wheels.

 

Yeah I know these are too wide for Brembos but what I'm more interested in is the sidewall ratio on these tires

 

Forgive me for my comprehension fail.

 

I'd probably be looking at a 275/40-19 tire in your case. Just a little more sidewall than stock, and almost an inch wider, and about the widest tires that will work well on a 9" wide wheel. They just over 2% taller than the stock 255/40-19 tires, and there are a lot of tires available in the 275/40-19 size, including the Pirelli P-Zero tires, and they are even a little cheaper than the stock size.

 

This is a nice tool for measure the difference from stock of a number of tire sizes. I think the general rule is to stay within +3% of the height of the OEM tire to avoid any issues.

275/35/19 would work efficently over the stock 255/40/19s.

Stock.
Section Width: 10.03in
Sidewall Height: 4.01in

275/35/19.
Section Width. 10.82
Sidewall Height: 3.78

So you'll gain about 4/5 of an inch of rubber to road. And lose about 1/4 of an inch in terms of height...

You could try a 265/35... which would run you a 10.43 width and a side wall of 3.65" but in terms of which tire would be better- the 275s would fit better onto the rim.

 

Id like to see a 275/40/19 on the brembo wheels... that seems like a nice size.

I dont want to thread hjack...but if you were to get winter tires put on a brembo rim what size n brand would you go with?

OP if your dropping the car i wouldnt go with a bigger tire (sidewall height) IMO

 

I plan on going after these, they have the best reviews of tire rack and have a nice 300+ treadwear rating over the rest of the max performance tires.

set of 4 come in just under 1000, nice price too!!

 

I really, really wish Bridgestone made their RE-11s in 275/35/19.

 

The Continental DW seems like a very good choice from the reviews I've read. Not the last word in ultimate dry grip for autocross or track usage, but great on the street and in the rain. I plan to get a set for my GT next spring.

Unfortunately none of the "Extreme Performance" summer tires like the RE-11, Dunlop Star Spec, Kumho XS, Hankook RS-3, etc are available in a good size for the Brembo package wheels. Several of them (the RE-11 and XS) are made in the 285/35-19 size, and it would probably fit on the 9" wide wheel, but all the manufacturers recommend a 9.5" wide wheel or wider for that size.

 

i wish the brembo rims were 9.5 wide that would have been awesome.

 

Yeah, it's very annoying. I don't think I'd want to try to run the 285/35 on these wheels. I might get the Mustang RTR wheels just so I can fit the RE-11s.

I've seen that one before. I just wouldn't be comfortable with it as it's outside Bridgestone's spec (they specify a maximum tire width of 275 on a 9" rim).

 

u just bought nitto 555 ZR's. 275/35r19


.45" lower profile than stock 27".


the worst thing that can happen with too wide a tire is inner tire wear. it willwear out in the middle pretty early.

 

I replaced my P zeros with 275/40ZR19 all around, as my tires were about shot at 11k. However, when I take a right turn, I hear a buzzing in lower right footwell. I don't know if the tires are the issue as they are oversized for the front, and may be causing this sound from the electric steering. Dealer wasn't concerned, but I think I will have them check it a little more thouroughly after the holidays.

 

Is your car lowered at all !
