Anybody else install a set of 235/35R19 Tyres on the Factory 19x7.5 SRT Rims???

It came recommended to me from a "Buddy" of mine... he even sent me pics of tire fitment and several autocross wins.



I'm just wondering how hacked off the tire shop is going to be at me.

Proof is in the Pictures:

That's a reasonably large diameter difference.

try it against our 225/45/19 size (or you can select dodge>2008>caliber srt4 in a drop down)

http://www.1010tires.com/TireSizeCalculator.asp

Those are a little over 5% shorter than ours, your speedo will be off.

I'd recommend a 235/40 or a 245/40
I'm still on my stockers, so take that with a grain of salt.

235/35?!?!? i wouldnt do it, but thats just me. 255/40 is perfect in diameter but too wide fit safely on our wheels.
On the other hand, 245/40 is perfect but the diameter is about 3/16 - 1/4 inch less, which doesnt matter IMO. 245 is what i am goin with.:bigthumb::bigthumb::bigthumb:

I completely trust my "Buddy".... I was just wondering if anyone else had done that drastic a change on the stock wheels.

I ran the calculator... and I could give two craps about the speedo error.
I want to put the most meat on the ground, and retain the stock 19" Wheels.

I am looking to run in G Stock Class in the Solo II Events this coming summer.

You should care, as it will change your overall gearing slightly which could have a negative effect. Think about it. You have a smaller diameter tire, so you now have a lower overall gear compared to the stock diameter. It will be easier to break lose a smaller diameter tire. Now that you have a .4" width increase, the two may cancel each other out and may perform no different than stock. And you're speedometer is off too.

x2 And most tire shops will probably prefer more sidewall, their easier to mount.

If your wanting more meat on the ground grab a set of 245/40/19
Its less than one percent size difference and will mount on our 7.5" wide rim, though its recommended for a 8" it will do just fine.

Nitto NT05 245/40!!!:bigthumb: they have such a stiff sidewall that u would think the profile is lower and u get "More Meat":jester:
Also, i know it cost money but get a better suspension if u wanna go around a corner better. them mopar sway help alot.

Id probly go with some Nito Invo's come spring/summer. Theyre about the same price as the NT05, but much more thread life.

Id agree going with 245/40/19.

With 245/40/19 - You are 0.97% difference (too fast)
With 235/35/19 - You are 5.57% Difference.

It all depends on the manufacture specifications:

235/35R19
Rim Width 8.0"-9.5"
25.5" Diameter

245/40R19
Rim Width 8.0"-9.5"
26.7 Diameter

245/45R19
Rim Width 7.5"-9.0"
29.6 Diameter


I don't want a tall series tire... too much flex on the sidewalls.

I am going to get a set of the 235/35R19 Tires and I'll let you guys know how it turns out, and how they perform.

They come highly recommended from my "Buddy", and I trust his mechanical input... so I won't be the first to put them on a CSRT-4.

so wait now 245/40 works for the stock rim with no issues?
The manufacture that I am looking at recommends a rim width of 8.0"-9.5" for that series tire.

So with a little extra forearm you could probably get them to squeeze on.



Another note:
I am talking about running these tires on Stock SRT 19"x7.5" Wheels, and completely Stock Suspension.

Dont think they are recommended, but I do believe 245/45 works with the stock rim.
I think that tire will fit the Stock Rim...

But that series of tire weighs almost 30 lbs....
the 235/35R19 weighs in at a little under 25 lbs.

Tyres have been ordered... they'll be here the first of next week since they are coming out of Louisiana.

I'll get them installed the same day they arrive.

We'll see how much ky I have to use to get them to fit the Stock Rim.

I've got 245/45 winter tires on my stock rims now. I've been running them since December with no issues/no rubbing.
