Need wheel and tire opinions please

[ss camaro-monte]

So I have 20x9 American Racing Crossfires in front with the stock 245/45/20 on General GMAX RS

20x10.5 American Racing Crossfire with 40mm offset in the rear (I have two sets of these, one has drag radials) Currently on one set I have stock 275/40/20 General Gmax RS and the other I have nitto r2 drag radials 275/40/20

Here is the question: I want to go bigger in the rear either 305/35/20 or 315/35/20. There is actually still tread on the GMAX RS but my car only sees 4k miles a year and they are aging out and getting pretty hard. Been on there over 3 years now.
These are the 3 tires I am looking at for the rear when I am not running the drag radial set up.
Vredestein ultrac pro 315/35/20
Contintental Extreme Contact sport 02 305/35/20
General Gmax RS 305/35/20

I am leaning towered the Vredestein which I have heard good things about and a friend has on his car but is 315/35/20 going to fit well on a 10.5 wheel. It says minimum wheel width is 10.5 wheel for a 315 and I wanted to get some opinions from you all that have done either 305 or 315 on a 10.5inch wheel as a lot of guys with 315s are on 11 inch wheels.

Also, my rear suspension isn't stock. I have all BMR rear suspension and viking coilovers and 460rwhp. Thanks

I've run these tires ever since the car was new, except in the 315/35/20 size on a 10.5 wheel, no issues, ever! Here is a pic of them.

Did you have to move the parking brake cable or wiring harness along driver side? I am assuming you look lowered too at that time? If not I am assuming a 315 would work and since I have coilovers I could adjust up a little if it rubs. Right now I am at stock height in rear and I have the front vikings I need to put on with factory zl1 sway bar that I need to do in the next few weeks. If I can fit the 315. I would just put 275 in the front then too.
Sorry for the late reply, been adulting. Lol

No, I didn't need to move/ziptie the cable out of the way, and yes I am lowered 1.25 Pfadt springs on all 4 wheels, and in that pic have the 315/35's on the rear, and 275/40's on the front.

Ok cool thanks. I am probably either going to go with the vredestein or continental. Continental are superior but most of the tests on the vredestein are pretty darn good for about 400 less out the door for all 4. Either way it probably will be much better then what I have now as going from 245 to 275 up front and from 275 to 305-315 should make a dramatic difference.

I am probably ditching the bmr anti roll bar. It does help it hook up but it is just to damn noisy on a 90% street car. Going to put factory zl1 bars I got from FasNuf on the forum off his zl1 when he went to Hotchkis
Thanks again

Yes sir! Sounds like a good plan. I have seen on here where more and more of the guys are running the Vredestein tires and are happy with them. GL
