Anyone running this size tire on the factory 20x8.5 wheels? I'd like a little wider contact patch if they fit, height difference is negligible

Adds ~1" diameter (+220/254ths if as labelled, to be exact-ish)

I would suggest a bit of caution. Wider in front may cause tight-turning issues of the wheels feeling as if they are climbing themselves in low speed hard turns.

Why a wider patch? I occasionally run my truck in corners. I did "my" exit/entry at 52-55mph with the rear hanging the entire way this morning with stock tires.....I don't need a wider patch as it's break-loose point is vastly predictable now.

If you want a safer bet, try 285/50r20's. It's wider, and is a direct replacement size. I'm running that size on my 2000. As Jeff suggested mount one on a front rim, and check for clearance, lock to lock. It's only slightly wider, but will give a nicer look, and handle a bit better through corners. The trade-off is a slightly rougher ride.

That would be wider but shorter on overall height. Are you sure you didn't mean 285/55? The same overall height but wider you would need a 305/50

No

For tire size:

***/YY rZZ

The formula is:
Width: *** millimeters (!)
Height: YY percent (!!) ...of the metric width...
Rim diameter: ZZ ...inches (!!!)

So overall wheel height is:

ZZ + [(*** ÷ 25.4) × (2 × YY ÷ 100)]


Inches of rim plus (width converted from mm to inches times 2 times percents height divided by 100 to convert from percent to multipliers)

Its the most convoluted mess of a measurement system known to mankind

So in short, NO... 55 "height" tires are NEVER the same height for different widths on the same rim size


Meanwhile, 285/50r20 ~= 275/55r20 ~= 255/70r18 ~= 275/70r17 (fairly close)

...also the 285/45r22 seen on 4th gens is pretty much the same 32" all over again

I have 11.50 wide up front and have no tight turning issues and that’s with 1.25” wheel adapters too
