Has anyone had 275/35-19 mounted on stock rims on the front of their car?

Anyone know if it will work on a stock ride height car with no rub?

Thanks for the reply.

Is this on the stock rims?

What size and brand?

This would surely reak havoc with Traction Control.

Calculator based mathematical equations of the sizes entered,
Compare: 255 /40 R-19 TO: 275/35 R-19

Front to Rear Diameter comparison: 25.5 TO 26.85 = +1.35
Front to Rear Circumference Delta: 80.1 TO 84.37 = +4.27

Looking to pair these with shorter rear tires. Probably 305/30-19.
You should calc the percent difference in diameter front to rear stock vs new and compare the change in stagger ratios.

Stock front: 27.0
Stock rear: 26.8
Front to rear:1.0075

275/35-19 front: 26.6
305/30-19 rear: 26.2
Front to rear:1.015

Change in stagger ratio: 1.015/1.0075 = 1.0075 or 0.75% increase in stagger ratio from stock.
1% change will not throw off traction control.

I've been running MT ET drag radials all winter rear 305/35-18 = 26.4 with stock size fronts (1.5% increase in stagger ratio) and no issues with traction control.

Tire Rack shows a little difference. Stock F/R, there's only a .1" difference in diameter (27"/26.9"), which would grow to a .3" difference (26.6"/26.9). I'd say this is well within normal ranges. After reading Chas' thread, I'm still torn on what size for the fronts this summer. I wouldn't mind a tad taller tire, and width, to fill out the wheel well, and add a little grip for the road courses.
