Wheel width for 315mm squared?

[roguegeek]

I used 11" from and 11.5" rear. Both worked well with BFG Rival 1.5's at 315. I think a 12" width would be better for a 335, but I'm not sure how many manufacturers are still making that width.

How do you normally have your tires set up with the offset wheel widths? 315 squared?

I'd do the 11.5".

11.5 if sticking with 315 or 11.5 for 315 with the option of doing 335?

I was referring to the 315s with option to 335s. Originally I was thinking a 12" would be better, but interestingly Falken didn't recommend more than 11.5" on the 315. Based on dontlifttoshift's feedback a 12" setup would be more ideal even for 315s, and better especially if you went up to 335s later on. I prefer having the overall rim width (outside to outside) at least as wide as the overall tire width if possible. It'd be better if you really decide which size you want to go with first.

My front and rear offset were different, as were the widths. So while I had 315's at all 4 corners, I couldn't rotate anything without unmounting / remounting (if this is what you were asking).

I personally liked the fit of the 315 Rivals on the 11.5" width also.

Best suggestion I can make... Get one of the wheel fitment tools and the tire you plan to run and test very carefully to make sure you are getting everything correct in terms of fitment if you are going to squeeze a 335 under the car. The shape of the Camaro wheel openings make it a little tighter than the Firebird (which I had). And if/when in doubt on offset, I'd go a little conservative and use more offset (I think that's how it's stated) as you can always use a small spacer to push the wheel out if needed (as in a 1/4" size or so, don't go too conservative).

I just mounted a bunch of 315s. Falkens look way better on a 12 than on an 11. Also, not much difference between the Falken 315 and BFG 335 on a 12.

Yokohama A052s always look stretched because they don't have a rim protector molded in but I can confirm that they mount easily on a 12.5" rim and have seen them on 13s.

I am pretty sure you can run 12" wheels square on that car with that suspension so I would.

Thanks for the feedback. I'm less concerned with how they look on the car and am more concerned I'm running an optimal setup. The car will accept 12" all around, but in talking with the Speedtech guys, I'm finding everyone is moving away from 335 and sticking with 315, which is what I'm very likely going to do. I was just asking about 335 flexibility, but it's really not that important to me here. At 315 squared, you'd still recommend 12? Even though Falken doesn't recommend over 11.5?

I'm set on 315. I was just wondering about 335 compatibility, but it was just to gather info. 335 shouldn't be taken into consideration for this particular decision. Thoughts?

I would follow Donny’s experience here.

The advertised tread width for the BFG Rival 315 is 11.7”. I personally would strive to run a 315 on a 11.5-12” wheel mounting width to stay in line with the tread width. Doing so keeps the shoulders of the tire squared. A 335 on the same wheel would be “pulling over” the shoulders of the tire slightly.

Yup. Let's throw the 335 conversation away at this point then. I'm going to be running 315 squared.

Yes, I was asking for the purpose of rotation. Thanks for the details here. For this particular wheel purchase, I'm only considering 315. At this point, I'm leaning towards 11.5, but I'm all ears to hear more experience on this.
