Upgrading Tire Size....thoughts

[Whipple Bullitt]

Your numbers are right.
Without the lowering it would have accepted 20in I’m pretty sure

19 inch 9.5 in the front and back? That would be the only way to get the 305 in the front right? and is that 30zr 19?

305 is too wide of a tire for 9.5” wheels. It’s going to bulge. You can go 10.5” up front for a 305 tire. Would recommend going 19” if you go that route

You mean for the 305/315 setup? A 19-inch rim @ 10.5 for the front and back?

Okay, I'm back. After trying the 265/40R19 and 285/40R19, and recently gaining more horsepower, I was convinced by my mechanic that I need better tires.

if I go with this wheel size (20" x 9.5" 20" x 11 ) what size tire could I run in the front and back?

I bought used gt350 rims and put 305/30 19 all the way around, fit great. Conti ec2's hook hard, feels like driving a go cart. I think the the fronts are 10.5, rear is 11.

I’d do 19x10.5 up front for the 305 and 19x11 in back for the 315

30zr or 35?

30zr or 35?

Either one, whichever you prefer. 305/35 is a tough size to find, pretty limited options in a summer only tire.

 

[Whipple Bullitt]

Not much 35 stuff in 19in, lots in 20in.
A warning though, if you’re going 305 on the front get some kind of splash guards on. Unless your world is 100% clean asphalt. Rear quarters will get sand blasted.

I’m gonna go 295 in the front

Gonna keep it simple with these.

Need something to allow me to increase the tire size and show off the drilled and slotted rotors.

Hopefully, they aren't too heavy. I think someone in here commented about the weight of certain rims, impacting handling.

Hey Golgo69,

A Great choice. I have 4 sets of these in stock.

Also have some weights, per wheel:
Front (19"x10.5")32 lbs (14.5 kg)
Rear (19"x11")31 lbs (14.1 kg)

Not too bad for an OEM wheel. There are certainly lighter wheels like out there, Velgen, APEX, and Billet Specialties come to mind, but for street use, these are great.

To answer the question of weight: Yes, a lighter wheel and lighter brakes will improve the handling characteristics of any vehicle. This is called unsprung weight.


Lower unsprung weight improves handling, acceleration, and braking because it reduces the inertia the suspension must control and allows the wheels to respond more quickly to road changes. For example, lighter wheels (like the Ford Performance PP2 wheels mentioned earlier, at ~31-32 lbs each) enhance responsiveness compared to heavier ones.

All that being said, this is more of a concern in race applications (Autocross, HPDE, Track)
On the street, the difference is there, just not as noticeable.

If you need help placing and order or have some more question, I can be reached at EXT 2170 and [email protected]!

Awesome Man. Thanks! I definitely will be sending you an email!

Quick question. Didn’t the PP2s come with 305s on the corners? Did they come with staggered rim sizes?
just curious

I believe that’s correct on the tires. Wheels are 19x10.5 front and 19x11 rear

Man, I started this thread in 2022!!

Well, it's over now!

After over a year of your suggestions (which are greatly appreciated), I finally got bigger rims and tires. I worked with Sergio from Steeda (above), who helped me immensely!

They came in on Sunday. I went to a shop, had the tires mounted and balanced, then took them home and put them on. I'll get an alignment today. Please excuse the tires looking a little ashy.
