20” RTR Tech 7 Wheel on Dark Horse?

[ChitownStang]

So, I have a non-hp Dark horse that I want to get an all-season wheel tire setup for 6 months of colder weather here in Chicago.
Never had 20” wheels in my last 3 mustangs.
Just ordered staggered setup mounted from tire rack and I’m second guessing.
RTR Tech 7 w/ Continental DWS 06 sport tires
20” 9.5”wide 275/35 fronts
20” 10.5” wide 315/35 rear
How will this ride, corner , etc?
Much less rolling weight per wheel.
It’s should look aggressive and fill wheel well more, but anything bad about this setup other than looking awesome?
$3200 mount and shipped to my door

on running 20's: a little on the thin side vs what you can fit underneath the car, but otherwise rides a little more rough due to larger rim, not really that noticeable though. more tread on the road will always handle better vs what you've got

on winter use: if you plan on driving in snow, dont bother with AS tires, keep your old set of rims and slap some winter specific tires on them.

No snow driving, just cold and dry days.
I did last 4 winter season on these tires with my Mach 1 , but 19’s 275/40R19 squared.
This will be the widest tires on rear I’ve ever had , and biggest diameter ~ 1” larger on rear.
What do you mean thin side” the side walls?

no just width wise, you could easily go up to 20x10 with 285s with no issues up front.

I thought the front rear rake would be aggressive with this setup.
It’s how Steeda sells their 20” setup for their Trident wheel tire combo except their wheels are 10/11” so little wider wheel same tire size

Aspect ratio is the word. Decent all weather tires, especially those for deep snow areas, have tread wrapped around part of the tire's sidewall. Low aspect ratios obviously limit that.

Have them on my 24 GT with the exception being 305's on the rear. I have been pleased with the ride thus far.

Looks great! So 305/35r20 ?
I will need to look up the diameter to see how it compares to the fronts

Yes fronts are 275/35/20 and rears are 305/35/20

They don’t have that size in the DWS

 

[ChitownStang]

I’m just hoping the increased height in the rear won’t mess up handling.
Also , will speedometer be an issue ?

The wheels/tires in the pic are my summer setup. They are 20x9.5-275/35/20 and 20x10.5-305/35/20 with Continental ExtremeContact Sport. I have a winter setup which are 20x10-275/35/20 and 20x11-315/35/20 with Continental DSW06. Low speeds the speedometer is fine but highway speeds it's about 3-4 mph off.

So do you like the summer or winter setup better or you can't really notice?
Looks like the Michelin's all-season have a 305/35r20 but substantially more money, $160 per tire.
Both say ideal width is 11 but the range is 10.5 at low side.

It's close, but to me my summer setup is a lil bit better in terms of grip. Both perform well in wet conditions. Imo both the Continental and Michelin are great can't go wrong with either. I chose the Continental because they're slightly less in price.
