Wheel Width - What would YOU do?

Recommended Posts

I'll soon be trading in my 2011 Coupe with SVTPP for a similar 2012.

 

I've already purchased a set of Ford Racing 19" x 10" SVTPP wheels for a set of "daily driver" tires. However before trading-in the car, I have the option of trading-in the car with the OE 19 x 19.5" front wheels or the 19" x 10" from Ford Racing.

 

From a sheer handling perspective, the 19 x 10 is the better wheel. Especially with a 40-19 tire, there's enough sidewall to be comfortable AND handle well with either wheel width - although the 10" wheels DO limit on the low end how narrow I can optimally go.

 

Here's the rub. The replacement cost for the 9.5" wheel is over $1,000 from the parts counter, whereas the FR 10" wheel is less than $400. From the perspective of sheer value proposition, I'm temped to keep the 9.5's for myself. For the dealer, there'll be no difference in the price it can ultimately command.

 

So.... what would YOU do - and why?

Sort of bummed to here you are selling your 2011 SVT. I've been anxiously waiting for you wheel/tire project to be completed. Looks like I will have to take the lead.

Oh, there's no interruption on that front. Still a work in progress - as I'm working through diff/gearing options to go with what will actually be a LARGER diameter rear tire too. I'm probably going to have to wind-up milling my own 6.96 ring and pinion set. :)

 

About the 9.5 vs 9.10 issue, that's what I've been thinking - as the 9.5s, better or worse, are 3 x the cost to replace - and a 10" front wheel really DOES limit the possibilities for front tires, which is fine for the track, but not necessarily what I'd prefer on the street where I'd almost prefer a 255 or 245 for a lighter feel and less dodge and pull.

Update, as it turns, out, 9.5/10 really lays at the cusp of some pretty serious decision points, particularly for anybody planning to widen the rear.

 

In addition to concerns about "rut seeking" (which probably won't be as bad with an A/S tire for street use), widening the rear by as much as we're talking will probably have some pretty severe impact upon the degree of natural oversteer engineered into the car - increasing it dramatically without ALSO widening the front too.

 

Unfortunately, we have opposing influences at play - wanting to increase hookup, but ALSO wanting to reduce the amount of rut-seeking, part of which will naturally improve through composition changes and partially though width - and even for street driving, I'd have qualms about going wider than 295 on the rear and narrower than OE on the front, a problem ALSO being how few 265/40-19 tires seems to exist - so now we're delving off into an entirely different proposition for anything narrower than 275/40-19's up front, and 255 is as narrow as most 10" wheels can accommodate - which is part of my reason for wanting to keep the 9.5s, as they can at least accommodate a full spate of widths.

 

Why do I sense I'm going to wind-up with 4 sets of wheels and tires by the time I'm done? :)

Will be sending-off my 20" rears to Weldcraft in a week or so. I just bought a complete set of SVTPP pull-offs - wheels and tires, so once they arrive and I can put them on the car, I can be free to live large on the rear, which I'm going to try FIRST with the Continental DWS 315/35-20's for everyday "street" tires - keeping the F-1 G: 2's for either the track or to place with the vehicle at resale. I'll be going with 275/40-19s in the front - though I'd even go to 285 if sizing were available, just to help maintain the over/understeer balance.

 

With now 3 sets of wheels to choose from, including 19 x 10 all-around if I so-wanted, I've really a wealth of possible combinations to choose from. I'd once considered going to 275/40-19's all-around as a more comfortable set of street tires, but the adjustable dampers should provide the benefit I would've gotten through the tires (without compromising handling) - and I can actually use a wider, but shorter summer-only or R compound tire in conjunction to finally bring-out of the 3.73 the extra torque it was meant to deliver on the track, where the smaller diameter will help to keep the revs closer to the sweetest spot of the range.

 

I'm VERY seriously considering guinea-pigging the 2011 I'm trading in to install a 4.10 or even 4.3 final drive - with the intention of dropping first gear altogether and adopting a more natural racing shift pattern - figuring it'd be worth the $500 to give it a try NOW, even if I were to give it away than do it and find out I don't like it in the car I intend to keep (at least to 2013). :)

FRPP has been testing a wider version of the faux PP wheel - wider than the 10" version. Keep your fingers crossed that it receives approval.

 

 

Would be nice if it were available in 20" x 10.5". Can't go much wider without considerably altering the offset. At <$400 a pop already, having the 19 x 10's widened may not be a bad option if Ford decides to charge significantly MORE for a wider version. With the 9 & 10 at $400 and 9.5 at $1,100, it'd hardly be unusual if Ford were to make a 19 x 10.5 inordinately dear as well.

 

I've just decided wheels and tires are going to be an ungodly expense, unless I'm content sticking with what the factory decided for me - so I've just bit the bullet - whole hog. Between 3 sets of SVTPP wheels and a set of 19" x 10" FR look-alikes, I'm pretty sure I can ensure I wind up with 3 sets of wheels that meet all my needs. :)

 

(Sh*t, I hope so, anyway).

I've got a few complete sets of wheels/tires as well. It's an addiction.

 

Sorry I can't provide more exacting information but I believe FRPP is testing a 19" x 11" version of the PP wheel. Everytime I am able to inquire I get the same response - that the wheel is on the street undergoing testing.

That'd be terrific - but I'm surprised they're going as wide as 11", unless they're going with a smaller negative offset to boot. My understanding was 10.75" was about as wide as anybody could go without altering the bump stop or shock boots, and I'd have thought Ford would've stayed well clear - to 10.5" maximum - though going to 11" makes possible a whole new spate of tire choices.

 

If the 11" involves spacers or a modified offset, they must be allowing for the fact that the outer sidewall will protrude beyond the fender arch.

 

P.S. Wouldn't it be terrific to know you could go to 750hp - even up the gearing to 4.10, and know 335's to help connect the crank to pavement could be a relative given?
