Tire decision help

[Kaisen]

I think most people on this site understand that modifiying a vehicle will affect handling and performance, yourself included, after all you are running bigger tires on your suburban.

My wheel and tire combo doesn't compromise safety or stability. And they're almost exactly the same weight as the stock LT245/75R16E tires and stock aluminum wheels.

Based on comments here and in related threads, I'd tend to disagree that people understand what compromises in safety they make when choosing 85 and 100 series tires that are 30+mm narrower than what their rigs came with.

But they still have that freedom. In Germany, for example, the TUV would never allow such a change on a freeway-driven rig. So be thankful you're in 'Murica where you can do whatever you please.

I never mentioned stability. your tires are 40 mm wider than stock therby putting more stress on steering and suspension components. The larger diameter tires also work the brakes harder, that is a safety issue. Also the bigger contact patch of your tires will put more stress on steering components and possibly make emergency manuvers unsafe

Sorry Kaisen,

all my Rigs are Streetlegal in Germany, and all my Rigs become bigger Tires...

My Pajero from 265/70 15 to 235/85 16

And my old Ford Ranger from 235/75 15 to 235/85 16

and everybody here in Germany have to bring the Rig to the TÜV for any kind of Mod.

We've been through this before.....the Sub 3/4 has the same basic suspension/platform as the Hummer H2 which was engineered for 315/70R17s.
So my Sub was fitted with H2 severe duty tie rod ends, upper and lower ball joints, control arm and swaybar bushings, and swaybar ends.
The wheels are factory H2, although the lighter stronger forged Alcoas from a rare version. This puts the geometry back where it should be.
The brakes might work harder (??), but again I run cryo-treated GM rotors hardened with Ferritic Nitro Carburizing and GM severe-duty Ceramic-Metallic pads....the same set up used on Secret Service Subs.

Good to know
I have friends there that cannot get certain wheel/tire combo approved by the TÜV on their sports cars, so I was reasonably certain it would be the same story

new tires for my rig, Yokohama Geolander 315-70-17 A/T-S. I like them a lot, they have a much nicer ride than the Kumo's that were on the truck when I bought it. The first two photos show why I needed to get new tires a bit sooner than I wanted, that was embeded up to the extractor ring at the edge of the tread area of one of the old tires:

Yeah, todays 1 ton trucks have good brakes. 315/70 r17 ain't no problem at all. Even some of the 1/2 tons are finally getting decent brakes.
