Will 315/30ZR18 fit up front?

[LA STIG]

Yes they will. With no rubbing or other interference issues. My track wheels are Sidewinder II's with 315 Hoosiers on the front.

Awesome!

Is this on an ACR with CCBs?

Any issues with ABS or Traction Control on an ACR with CCBs?

Yes they will fit with no rubbing and I have the lowering caps as well. I took a passenger out once though and they did rub at the bottom of hills on the track.
I used to have a traction control problem on the first straight of the track the light would come on, and wouldn't let me give the car much gas. It would go away before the first turn, but this has somehow magically gone away so I'm thinking it was something else now...

MIne does/did this when I put the 315s on for the track. I turned off or down the TC and didn't happen anymore.

Are the tires a lot taller than the stock 295s?

According to my calculation a 295/30/18 is 24.97 inches tall. A 315/30/18 is 25.44 tall. 1/2 inch is an insignificant difference IMO.

1/2 an inch in the front of a Viper is a lot IMO. We all have our opinions tho

[cab33]

What width of wheel are you guys running with the 315's?

[Arizona Vipers]

What width of wheel are you guys running with the 315's?

The factory Sidewinders. I think they are 10.5" wide. Car pushed like crazy for me with the 295's. The 315's cured that.

[Dr.Ron]

I just got 11". I'm sure some run factory 10.5 & many use 11"

11's are better for a 315. What wheels are you running?

[Dr.Ron]

I got Forgestars from Tony (nineball). Tires aren't mounted yet though.

Because the 1/2 inch is the total diameter difference it means the car will sit 1/4 inch higher (1/4 on the bottom, 1/4 on the top). Still don't think that is too much of a difference.

oh yeah 1/4" isn't that bad at all
