10" is a bit narrow, should be on at least a 10.5" and really an 11". The 315 is a touch wide and tall, especially if you're trying to match the front, what are you doing on that end?

I know it should be an 11 wide, but im trying not buy new tires since these are like new. I have matching 265/35/20. I ran these tires on my forgestar f14s

Yeah, I have MRR M600s too, same offset, 305 fits nicely, I'd suspect the 315 would be pretty good, it's only a touch bit bigger.

Though when I had my '16 (and these wheels), combined with BMR SP080s, it was pretty tight. My '19 (same wheels) I haven't touched the suspension yet, mainly because it's just so darn good with the newer PP + MR :)

OP, here's a comparison of the 305 on my 11" ET50 vs. a 315 on a 10.5 ET57:

So I'm the orange wheel, you're the green wheel, you can see mine and @Bybcous above actually stick out a touch further (mostly to account for the extra 1/2"). It's not that easy to follow but the really squared off black lines are the 305s, and the kind of trapezoidal black lines are the 315, you can see how they're slightly bulging on the wheel. I mean, I'm sure this visualization is a bit rough, but I think it's close enough to get a sense of the fitment.

The only thing I'd point out is that inner clearance on the 315 on the 10.5 ET57, up at the top (that's not a specific Mustang suspension or anything just a generic reference).

(Backspace isn't input as that's just calculated from offset and width ...)

Hope that helps, especially combined with the photos above!

A 315/35/20 tire is almost 29” tall. They should fit but that’s going to be some goofy looking stance unless you’re running a similar size up front. Even so, that’s a large diameter wheel and tire regardless of what it’s going on. I’d consider a smaller size

Wanted as wide as possible for the whipple. Taller size helps too because I have 3:73s.

That was partially my point, that the sidewall is way bigger on the rears. But you weren’t really asking about that. How wide were the F14’s?

20x9.5 and 20x11 i know the 315s are technically to wide for a 10.5 but they are like new, still 9/32 tread. So if i dont have to buy new tires that would be better lol. The wheels im looking at getting are 20" weld rts

A 305 isn’t too bad, just depends on how big it is. All tires aren’t created equal so they may be a decent fit. I have 305/35 MPSS on 11” wheels and they’re stretched a little. They’re oem gt350 wheels
