225/35 or 235/35 Tire For 19x8

I am a little confused, i know everyone recommends to go with 235/35/19 for the front 19" wheel and 265/30/19 rear.

But, considering the particular tires and wheels that I am getting, General Exclaim UHP, and the front wheel is 19x8, the overall diameter of 225/35/19 is actually a better match for the rear 265/30/19 and more close to stock 25" overall diameter of 225/40/18 and 255/35/18.

So my question is why no one goes with 225/35/19? Besides "the wider the better" mentality. It's 3lbs lighter, it matches the stock diameter better, and it matches the popular 265/35/19 rear better. Just trying to get some input for my decision.

Here's General Exclaim specs, I posted 265/30/19 as well to show a closer match with 225/35 vs. 235/35

225/35ZR19
Load Index 88 = 1235lbs (560kg) per tire
Speed Rating “Y” = 186mph (300kph) 88Y XL Treadwear: 380
Traction: AA
Temperature: A380 AA A
1235 lbs.
51 psi
11/32"
21 lbs. 7.5-9"
8"
9.1"
NA
25.2"
831

235/35ZR19
Load Index 91 = 1356lbs (615kg) per tire
Speed Rating “W” = 168mph (270kph) 91W XL Treadwear: 380
Traction: AA
Temperature: A380 AA A
1356 lbs.
51 psi
10/32"
24 lbs. 8-9.5"
8.5"
9.5"
25.5"
819

265/30ZR19
Load Index 93 = 1433lbs (650kg) per tire
Speed Rating “W” = 168mph (270kph) 93W XL Treadwear: 380
Traction: AA
Temperature: A380 AA A
1433 lbs.
51 psi
10/32"
23 lbs. 9-10"
9.5"
10.4"
NA
25.3"
828

As you can see the diameter and revolutions/minute are closer to stock in 225/35 case. Also it weighs 3lbs less than 235/35 and that's a lot, when we're paying huge money for various lightweight forged wheels.

Thanks in advance, remember the front wheel is 19x8 I'm using

The only reason people may tell you not to use 225/35/19 tire on your 19x8" is because it does not maintain the factory stagger of +3mm from front to rear. Most may say by using a 225/35/19 with a 265/30/19 would increase the under steer characteristics of the car. However, from personal experience, I do not believe it is a significant enough change in section width to make any discernible difference in your handling. Most of the experience has come from HPDE and spirited drives on the local twisties.

Thanks for a quick response, so you think it'll be fine either way 225 vs. 235.
