I have a set of American Muscle 19x10 GT500 replica wheels on all 4 corners and am currently running my stock Pirelli's that came with my track package car. Obviously, they're a bit stretched but I didn't have the funds to buy new tires at the time. Now I'm getting ready to so I'm wondering if either a 275/40R19 or a 285/35R19 would cause any rubbing. I want to keep the size the same all around so I can rotate the tires.

My car is currently lowered 1.5" on SR Performance springs. The wheels have a +48mm offset and 7.39" backspacing, if that helps.

 

The 275/40's should be fine. I run that size on the stock TP wheels with no problems. They should stretch a little on the 10 inch wide wheels.

 

Cool. I ordered a set of 275/40R19 Hankooks yesterday. They should arrive today or tomorrow. I'm looking forward to getting them on. I will probably continue to second guess myself for not going with 285/35 though.

 

The 275/40 gives you a couple hundred more rpm in each gear since they are a smudge taller than stock OD. You will be going 61 when the speedo says 60. The 285/35 is the opposite. I like it with the 3.73 TORSEN. Since first gear was almost useless.

 

Cool. I didn't realize that

 

All about pulleys. Do 285/35's yeah you lose maybe 1 mile per gear but the grip is awesome and the 35 side wall feels so great.

 

Agree on this for sure. The 40 is a little squishy when I am zipping through the curves. The ride is nice though.

 

19x10 can easily mount a 295 or 305...just saying.

 

In the front, on a lowered car, without rubbing? That's the question I was asking. I know that those would fit in the rear.

 

If Vorshlag can fit 315's on stock fenders then you can too.

 

Vorshlag was using a 18" wheel. But indeed, it can be done on the front of a lowered mustang w/o rubbing. Worse case you run a spacer to correct for offset.

 

I'm planning on the same sizes considered here, for the front of my lowered '13 which will receive 19x10 AMR wheels.
Really considering the 275/40/19 size more for several reasons: A better chance it won't rub, it's taller than the 285/35 so it will raise the front-end about a 1/4"-1/3" over what I'm using now (285/40/18), and it will be closer in overall height to the 305/35/20 that I'm gonna be running in the rear.

OP, which Hankooks did you order?
I'm looking at the V12's myself ... found them for $177/tire on a weird website, waiting to hear from Discount Tire Direct if they'll price-match it

 

I went with the Hankook Ventus S1 Noble 2's for multiple reasons. The two biggest are the fact that it's a daily driver so I wanted an ultra high performance all season tire, plus they have a 50,000 mile tread warranty. The Pirelli P-Zeros my car came with are like driving in hockey pucks below 40° plus most people say they're only good for 20,000-25,000 miles.

 

Fwiw, I'm running conti dw 275/35 on 19x10 square setup and wished I had gone with 285/35. Glad I did not go 40 series. My springs only lower about 1/2" but the smaller sidewall drops it a tad further. IMO, stretch is a bit much on the 275s and the smaller OD doesn't help. Think steering sensitivity.

Btw, did you check clearance to the front upper swaybar end link bolt with 10" wheels up front?
