Anyone else think that they will be too small and affect the ride quality badly?
I believe 6% is way way over limits for not damaging drivetrain, think I heard max 3% off OEM but don't quote me...here is a nifty calc to show the exact diffs between the two

Re: Winter Tires- summary thread

If all 4 are the same size there is no rotational difference for the transmission and ABS to deal with. Ride may be a different story but you don't want different front and rear sizes.

Yes, that was it Thanks for clarifying. It's 3% max diff for staggering since more will toast the transfer case since it will have 2 shafts rotating at diff enough speeds...

Here is a calc for OEM (think I got yours right) 20x8x56.4mm shod w/ 265/50/20 and the SRT8 reps at 20x9x34.55mm shod w/ 275/40/20. If I am wrong just change it in the calculator.

My concern for Chevsux is not the 6% speedo/odom error (can be corrected) as much as the effective on vehicle width....the SRT8 wheels will stick out 1.1 in. more than current...besides maybe looking funny you may have a fender lip clearance issue when working the suspension and omg the debris you would be throwing at your side body...just my thoughts....

here's the best tire size calc to fiddle with:

Interesting.
There is a lot of fud out there, where folks who don't have both stud and studless winter tires try to claim superiority for whatever they sell.
One rip against studs is the [demonstrably false] claim that they have harder rubber compounds that don't handle cold well.

Of the few companies that sell both studded and studless specialty winter tires, I have the choice of believing you, or experts such as Nokian who clearly note the superiority of studs on ice, wet ice, intersections, etc.

Or, the Alaskans, Montanans, Coloradans, who drive on hard frozen icy roads that get a nice layer of liquid on them with traffic who just buy premium pre-studded tires and get rear ended by folks who claim studless can stop or turn as fast.

Re: Winter Tires- summary thread

Anyone ever run the AMP 265 50 20 on their Jeeps? I was going to go with a set of the Nitto Terra Grapple G2 265's but they are only rated M&S, where the AMP's are an all weather with the snow flake?

Winter Tires- summary thread

Hey all- I'm new to the SRT - just got a low mileage new to me 2015. I have my 265-50-20 Hankook iPikes that I ran on my old WK2 Overland. I know these are nearly identical to the SRT stock height.
My question is in regard to wheels. I can pick up some Overland original 20" wheels fairly cheap - locally- will these clear the SRT brakes and calipers, or do I need a wider rim or other offset?
Oh, and I have Googled and Binged and searched the forums, but I really only come up with people putting SRT wheels on non SRT Jeeps. Thanks for any help or links

But agreed, for typical drivers, they aren't really needed.

Worse, many of the dealer installed studs have the bad habit of coming out of the socket at high speeds. Only the Nokian factory studs avoid this and have awe inspiring top speed ratings to my knowledge. The Nokians are quite noisy, worse than any others I've used, so buy em only if you really drive enough in horrific cold ice covered roads enough to benefit from the difference.
I'd say WI qualifies as a state where they'd be needed at times, but...

"Studded tires are not permitted, except for authorized emergency vehicles, vehicles used to deliver mail, school buses from November 15 to April 1, and automobiles with out-of-state registration (only if in the course of passing through the state for a period of not more than 30 days)."

It's been that way here almost as long as I've been driving. None of the departments I worked for ran studs on their squad cars either.

Overland wheels will not clear Brembo's. Look for some Jeep SRT wheels.
They seem to be fairly common on Craigslist here.

Re: Winter Tires- summary thread

Found these local to me- owner says they are from a 2014 - I believe they are, but is there anything that I should look for that will give away replicas as opposed to Mopar original? Thanks. I also think they are 20x9 wheels- what's the name of this style?

Re: Winter Tires- summary thread

If they are mopar original they will have SRT on one of the spokes, and jeep embossed on the centre cap. Alcoa foraged on the side of the rim for the newer ones. From the pics those look like replicas, I just sold a set like that from my old SRT, they will stick out an inch or so further than stock too.

Chevsux, Why will they stick out an inch all around?
