I have an '06 H3 Base. It is not (yet) leveled. This weekend some poor 80 year old man sideswiped me at ~ 10-15 mph coming off a fwy offramp.

Anyways, I have 265/75/16s on stock chrome wheels and I'm working to make the most of an unfortunate situation and ordered 20x9 KMC XD Monsters in flat black (XD77829067718).

I was recommended 285/50-20 or 275/55-20 and wanted to see if anyone had any recommended tires or their 2cents to add. I guess the 50 series would affect any spedometer variance less. But any recommended brands, etc?

Thanks!
Eric

35/12.5/20s are the only ones that are not gonna ride rough. I ran 18s with 35s and it rode worse than stock

The 285/50/20 tires would be about 31.22" diameter (smaller than your OEM tires)
The 275/55/20 tires would be about 31.90" diameter (slightly larger than your OEM tires)

My 2 cents is that either choice would look ridiculously small on an H3.
You want to have at least a 33" diameter tire or even better a 35" diameter.

Nice job on digging up a FOUR YEAR OLD "how big of tires will fit" thread. :rolleyes:

oh. so you think that even the 55 series at ~1.1" smaller diameter difference would look ridiculously small?

crap. I ordered the Yokohhama Parada Spec-X today from Americas Tire.

What would bring it closer to the orig overall diameter? 285/65/20? I don't even know if they make those.

You need a WIDER tire as you go up in diameter. Look under 305, 315 or 325 sizes.

Really, 2 pages of discussion for some rubber band tires on RIMZ!

Im sure you are a smart kid and can find a tire size converter online and type in 285/75R16. Tons of converters out there...

I have 18" wheels and heavy tires and it's Killing my horsepower, not to mention its and 3.5, Does anyone have any suggestions?? I'd be tempted to put stock wheels and tires back on, but i don't have them.

Have PCMofNC tune your PCM to adjust for larger heavier tires and other options,

I ordered some 315/75 16's for my stock wheels yesterday.
They should make the truck look beefier
