Need help choosing tire size
 

My Wheels should be here in 2 days and I'm having some issues trying to decide which size tires to go with.

Wheels: front= 20x9.5 +25 rear: 20x10.5 +22

I plan on buying Hankook Ventus V12 Evo K110's

For the front I can't decide between 245/35/20 or 255/35/20 (biggest concern on the 245/35 is that the sidewall will be stretched some)

Rear - 285/30/20 or 305/25/20

Car = 2010 Roadster Touring Base completely stock, no mods...

Looking forward to your opinions...

I would think bigger. I would go with 265/35 in the front (no bigger) & 305/30 in the rear. I would possibly think about 315/30 in the rear.

It doesn't look like they make this tire in 265/35 or 315/30

225/30ZR20 85Y
225/35ZR20 90Y
235/30ZR20 88Y
245/30ZR20 90Y
245/35ZR20 95Y
245/40ZR20 99Y
245/45ZR20 103Y
255/30ZR20 92Y
255/35ZR20 97Y
255/45ZR20 105Y
275/30ZR20 97Y
275/35ZR20 102Y
275/40ZR20 106Y
285/30ZR20 99Y
295/25ZR20 95Y
305/25ZR20 97Y

Yea tire size selection for the V12 in 20" sucks. I currently have 255/35 in front and 295/25 in the rear. The sidewalls for both fronts and rear are super thin.

I bought some 285/30 as repclements for the rear to give it a little more meat. Not sure about the fronts yet.
