A052's 295 vs 315 on 11" wheel

[PatientZero]

I'm currently running 295's on 10.5" wheels. This seems to pretty a pretty good combo at least for autocross. I bought a set of 11" wheels so I can move up to a 315. Now I'm wondering if a 295 on the 11" wheel might be the better combo. Part of me thinks getting as much rubber as possible is the way to go. Anyone have any experience?

Just tell me I'm stupid and need 315's.

Definitly go for the 315 rubber. Its the Mustang size!

Youre stupid, go 315. I run ao52s on 10.5s

It's not a straight-forward choice in my book. If you're using 11.5 or 12" rims, then knock yourself out. If you've only got 10.5 or 11" rims, then I think it's a little less obvious of a choice. At some point, you start to weigh max grip and heat capacity versus response characteristics. When you pinch the sidewalls of the tires by putting them on too narrow of a rim, they start reacting strangely in transients. The poison is in the dose. On the flip side, if you put a tire on a rim which is a little too wide, you can make a tire a little sportier. The angle in the sidewall will give it a little extra lateral stiffness, which is nice, but generally a trick for when you're limited on tire width.

I didn't want to say that but.....

I think it depends if you want to get the perfect fit, or the better lap time. The Yokohamas list 18x10.5 as the minimum for the 315's. At least with R7's in 315 I found the feel every bit as good as 295's on the 18x11 wheels, just with more grip. But then again, have seen lap records set with 295/30-19 tires on 19x9.5 wheels, not ideal, but still fast.....(fellow had Hoosiers ok to run that size on those rims)

Ya, Mad, it might just come down to this.

I usually have the courage to say things that other people dont want to... lol

315s on 10.5 ao52

Do it

 

[Mad Hatter]

If she says its ok, then it must be ok. Though looking at the pics, I would like 18x11 a little more.

 

[Frank.JD.Perez]

Honestly none of this really means anything since you already have the 11s. Just run those.

I saw the other day that those Yokohamas are pretty good in the wet?

Yes.

I barely change my driving when it's wet, they are that good.

 

[Mad Hatter]

Thats good to know!

11 is better.
I won american cup on 295 on 11.. super flat patch.
315 yoko are better on 11.
315 in 10.5 can work? Sure..optimal? No

I'm specifically asking about 295 vs 315 yoks on a 11" wheel.

315 offers almost 1" more rubber. For our 3700lbs car is a lot of rubber that will make a difference.
315 A7 are awesome on a 11" (that is what i run)
295 were good but you clearly feel more the tire limit when driving at the edge. At least what i experienced.

I guess the answer is specifically 315 is better in any make. You have the 18x11 wheels so its kind of a non problem. maybe if you were only with the 18x10.5 wheels it might be harder to answer.... (would still go with 315)

 

[Stan Whitney]

315/18 yok's are stretched on a 18x12, so 18x11would be good.

I guess the reason I ask is because the 295's are slightly pinched on the 10.5s and I always thought they would be a better fit on a 11. I also see people putting the 315's on 12's. This is where my line of thinking came from. Just putting the 315's on my 11's is probably just a no brainer and I'm overthinking it. No way would I put a 315 yoke on a 10.5. I know it's been done but it looks like a balloon.
