Help with tire sizing -- Brembo wheels
Hey guys,
I'm due for a new set of tires and am currently weighing my options on three different tire sizes:
255/40/19 (stock) 27" tall
275/40/19 27.7" tall
275/35/19 26.6" tall
I am planning on running a square setup and keep in mind I have a 3.73 gear. I value handling more than straight line acceleration if that helps any.
With the 275/40's I'm worried that the tire might be too tall. I know I should have more ultimate grip than stock, all things equal, but I'm wondering if the 40's will look too beefy or have too much sidewall squirm. I do know I'd benefit with a higher effective gear ratio... I'd probably be able to run through the 1/4 in 4th gear without hitting the limiter.
With the 275/35's I would have an effectively lower gear ratio, but I'd probably pick up some more of that turn-in feel lost with the 275/40. Just worried that maybe this might be too short of a tire, and with my already low 3.73 gear if I'd negate any real gains in straight line grip with the lower effective ratio.
And of course I could remain at stock tire sizes at the (potential) expense of less outright grip.
Thoughts?

I'd go with the 275/35. I'm running 285/35/18's which are 25.85" tall. The 275/35/19 is much taller than mine. I am lowered, so it doesn't look awkward, and you're not going to be able to tell much difference in the effective lower gearing since your change is so small. A great performance/tread life tire in 275/35/19 is the Hankook V12.

Thanks for the input. Re: the V12s, they are not a bad tire. I had them on my 370Z before but I think the sidewalls are a little too squishy for me to use them again.
I think I am going to go with the Michelin Pilot Super Sports, in which case I am limited to 275/35. The only other option would be the Continental ExtremeContact DW's in either OEM size or 275/35 or 275/40... but the PSSs outclass them in every category.

I will definitely let you know. I need to make a couple big decisions about the car first. If I don't think I am going to hang onto it much longer I will probably get the V12s. If I think I will keep it I will get the PSS.

hmm, subscribing to this one. keep us posted. i was running the gt500 wheels w/285s out back on my 09 and loved em...Im a fan of my brembo rims but the tire width limitations might force my hand to check out some forgestars....

Anyways, I am leaning towards the PSS but kind of have my eye on the 2012 911 2S, so if that happens the Mustang has to go!

Any updates? I am in the market for tires now thanks to a nail in the sidewall of my pirelli's. I have almost 11,000 miles on the tires and I don't wanna replace just one with th emileage that far off. Was gonna do two but, my dealer wants $464 a tire (that includes road hazard and install). They sell tire for $5 over cost. Going over my options now. TIA
fyi- I have a Brembo pkg car. Pirelli P-Zero I'll take all your money tires.

These pirellis truly suck. Can't wait to get some PSS's!

I actually think the Pirellis are a great tire. They have good feedback and tons of grip. The car was way faster on The Dragon than my 370Z was which is saying a lot.
The only downside is the cost and tread life.

Got the Hankooks. 275/40/19's. They look good. Price was definitely way better. I'll update on how they feel. I've only had a chance to put a few miles on them. They were fairly quiet on the highway coming home.
