I have 275/55R20s on my Overland and it doesn't rub even on the lowest setting. Worst case you can get Nitto Terra Grappler G2s in the stock Overland size and they should definitely fit an SRT8. Personally I'd be more worried about 9mpg on your commute than the tires.

 

The SRT will fit any tire any non-lifted WK2 will. The massive brakes will limit the wheel choices. There were a few SRT tire discussions here maybe 6 months ago that you could try to search for. Otherwise someone should stop in within a day or two and provide info.

 

I think your math is wrong.
Stock SRT tires are 295/45-20 which are 30.45" in diameter.
275/55-20 are 31.91" so a difference of less than 1.5"

 

Yup....My math was wrong. WAY wrong.
One of the articles I read on the JGC-SRT said the OEM tires were 25" in diameter, and while I thought that sounded tiny, I foolishly accepted it at face value and kept devouring more articles.

Then, last night when I wrote my dissertation (above), those dimensions really got hung-up and made me actually start thinking about how oddly small they seemed so I went to the Pirelli site (where I also learned how to spell Pirelli) and looked up the actual specs on their P-Zero tires and came up with far more believable dimensions. After putting together a little spreadsheet (yeah, I really geek-out on things when they catch my attention) it seems like the real numbers look a little more favorable for my scenario.

OEM Pirelli P-Zero Run Flat 295/45ZR20 is
11.6" section width. 30.6" diameter. 9.5-11" rim.

My precious Falken Wildpeak A/T in 305/55R20 (aka 33-12-20) is a remarkably comparable 12.3" section width. 33.1" diameter. 8.5-11" rim.

So it kinda sounds like my fantasy just might be doable......ish.

As for my anticipated fuel efficiency....as a reminder, I currently commute at 80-85mph in a WRANGLER. Which has the gear ratio and aerodynamics of a Tricycle. I think my frankensteined JGC-SRT wont be any worse. And could actually be a bit better. Not better enough to make up for doubling the price tag.

Sooooo much to ponder.....

Not the least of which is making up some sort of excuse for replacing an Unlimited Sahara Wrangler with which I was 150% satisfied......until I saw that goram SRT. Grrrr.....

Lead me not into temptation.......(unless you also lead me to a means of obtaining said temptation).

LOL

Happy trails, all

Buy the darn thing. Figure out the details later.

 

This.

Not that mine's an SRT, but it's SRT wheels so they would clear brakes with All Terrain tires...

Oh, here's a good picture of it, the tires I'm talking about are circled in yellow:

 

The WK2 OEM wheels pretty well fill up the wheel wells, unlike the Wrangler where there is lots of room for improvement. Its something hard core jeep fans are surprised by. I don't think real 33s will fit without at least trimming some felt, flattening pinch welds, removing some wheel air dams.. If you can find tires 32.1 inch or less in diameter you have a shot, however.

As Roy suggested, buy it, figure out the details later

 

LMAO....If only it were that easy.

I would if I could but that might explain why I cant so I guess I wont.

For now.



THX again, all.

Pointless IMO. If you want a GC, get a Limited/Overland/Summit. An SRT with AT tires is dumb. Not only will the suspension and wheel/tire choice severely limit the off-road capability, the on-road performance will suffer dramatically as well by running AT tires. You'll still have plenty of performance from another trim level with a V8, and you'll save a bunch of money too!

Don't get me wrong, I'm not opposed to taking an SRT off-road, I just don't think it would be a smart decision, practically, and financially.

And a V8 Wrangler makes complete sense when you're running 40"+ tires and full lockers.

 

Now see....you had me right there with you on the common sense approach to the issue.

And then you had to go and say that V-8 in a Wrangler...and 40" tires for that metter...made good sense.

I think both are ridiculous...like putting a nitrous injector and a supercharger on a yugo.

I off-road for a living. Everyday. And I rarely find a need for 4wd, let alone clown-tires and an ever increasing number of ponies under the hood. Don't need ponies...you need mules. hahaha When you do it occupationally, you use your brains to drive around obstacles instead of using your balls to drive over them for recreation.

But that's the beautify of Jeeps....do whatever you want. Make it your own. If you want to put combat boots on a Olympic Sprint racer...go for it. If you want chrome (cringe) bling-away. If you want a snorkel on a vehicle without a sealed electrical system...have at it, looks cool. Want a cummins in your wrangler...get some vasceline and duct-tape and make it happen. The options and the opportunities are limitless.

But, again....I agree that there are likely better options to meet my needs.

Now I just have to get my needs...to ignore my wants.

 

Srt off road is dumb
Get a wk2 with 18 inch wheels, a lift kit and larger tires.
Imo, the overland with the air suspension is much inferior off road to shocks with a lift kit....
If i could, i would want my overland with reg shocks, i would install a lift kit.

 

Given 80% commute at 80+ highway, a full time lift is not that good, may as well stay with the Wrangler.

 

I beg to differ. I've never had any issues with my RRO lift and I commute 75% of my travel on the highway. There is absolutely no difference with the lift, the ride comfort is the same, even with my Terra Grapplers. It sounds like you want a V8 Limited with a full-time lift and 32"s IMO. It would serve you well and fit your application.

The point of the V8 wrangler isn't for "normal" applications. Check out some videos on youtube of Mel Wade (Off-Road Evolution) and Eddie (Wayalife). They do a series (presented by Nitto Tire now) called the JK Experience. Definitely not your typical off-roading, they take it to the extreme.

 

Just saying that taking a 50mph curve at 80mph with a lift can be quite exciting, a 60 mph curve at 70 may be uncomfortable..... not to mention the mpg penalty and that the kids have a hard time getting in. Spacer lifts typically don't change the ride, but the CG is significantly changed... which is what I'm more worried about. If I need a lift for an obstacle, I just pick ORA 1 or 2. But just compromising with a full time lift is also good if thats what you want and have no other choice... but thats just me.

 

I agree that there are certainly positives and negatives of both. Obviously, the decision is made most easily with the trim model you select.

 

Not interested in lifting.
Didn't lift either of my wranglers. Not gonna lift anything I ever get.
Just not my kinda thing.
Like I said, I don't off-road to play. I'm not trying to prove anything to anyone (including myself) as to how tight a spot I can get into and out of.

Allow me to ritterate the purpose of my inquiry... I was merely trying to determine potential issues of using an all terrain tire on an SRT.

The SRT suspension and clearance is fine. With skill and technique, a VW Beetle will get you most places you want to go.

My concern was primarily with the durability of the Pirelli street tires. I wouldn't expect to go rough trail hiking in feather-weight running shoes. Just as I would try to run a sprint race wearing a pair of combat boots ( as per my previous metaphor ).

I know that if I should ever actually aquire an JGC-SRT and I do ever put all terrain tires on it, I will obviously have to be less vigorous on the performance than with the street tires...the tire compounds are harder, less tolerant of higher speeds, the blocked edge treads don't cope well with high speed cornering...all those things that make a great street tire make a sucky trail tire and the inverse is true, as well.

If, however, the SRT still maintains the heart of a JEEP (which I believe is likely the case) then I think I can put the Falken Wildpeaks that I have come to love so much after hundreds of thousands of miles in all sort of conditions. I can still ride smooth on pavement, crawl over sharp rocks, roll over cactus and mesquite, and make a 1000 mile road trip to/around/from Big Bend without ever realizing that one of my tires is completely out of air...sidewalls are that strong.

Granted, I wont be drag racing against my wife's C6. I wont be proving to the state troopers that my top-end is higher than theirs. And I wont be trying to get the loose change and French fries out from under my seats with blistering 60-0 seat-belt-stretching panic-stop to show off my braking prowess.

But...I would be a bit more comfortable for 80% of my driving than I currently am with my ABSOLUTELY AMAZING JK.

Serious...absolutely no reason to even consider a different vehicle than the one I already have and spend so VERY much time in. Let alone reinvent the wheel (literally). But ya gotsta day dream about something while you're mozying around in the boonies.

wouldn't it be cool if this were an actual dilemma rather than merely a hypothetical hand-wringer....ohhh darn, whatever shall I do?

hahahah

Happy Friday, ALL.

Buy It already!

 

if I had to do it again I would get a limited with a lift kit and larger AT tires. Much cooler. Thats a jeep.

 

Wait until next year and pick up a Diesel Wrangler.

 

I haven't found any AT tires to fit stock rims, snow tires are even a challenge.

 

I know that I've talked about these so much that it seems that I must work for Falken...but I don't.

I just have a philosophy that I compliment when I'm happy as much as I complain when I'm unhappy. Some folks like to complain and forget to compliment. I'm just EXCEPTIONALLY with my Wilkpeak/Rocky Mountains (same tire, different label depending on vendor).

Take a look at the size/Specifications tab towards the bottom of this page. You see that the wildpeak is available in OEM rim size.
http://falkentire.com/tires/truck-suv-tires/wildpeak/t-tire

Odds are that it'll be special order for a 20" rim...but they are out there and are a hell of a lot more affordable than the more common brands....and have better professional and user ratings...just saying.

Here is a link to my posting about falken tires on the wrangler forum.
http://www.wranglerforum.com/f27/falken-rocky-mountain-33x12-5x15-on-chaos-5-a-209931.html
a bit verbose...but thorough....accurate...and honest.

As always...to each their own. I feel quite strongly that folks should run with whatever they like...I just happen to like these. :cheers2:

 

Yup, that's what I'm talking about,

I didn't see a second image or anything circled in yellow.

Am I missing it somewhere?

Thx

 

Am I missing it somewhere?

It was a (apparently bad) joke about the tow straps...

 

LMAO!!!!

Nah....I was just exhausted and fried...looonnnnng day in the sun.

But you have what I'm talking about. Just a reasonable A/T tread. Nothing that looks like I'm trying to "look" aggressive or pretentious.
