Largest tires on 16x8's with 2" key lift?

SOM Truck · February 4, 2004

Hello everyone,

I need some advice. Is a 285 the largest tire you can run on a 2500HD 4x4 with a 2" leveling lift? I upgraded to 265's when I first bought the truck, but I'm not happy with the size increase. These trucks are so large that it still makes for a tiny looking tire. So now I'm looking at some aftermarket wheels (16x8) and considering a tire size upgrade. I'll keep the stockers with the 265's for heavy load hauling.

Any advice or experience would be appreciated.

I'm also hearing that Bilstiens are great replacement shocks, but should be used with a 1" spacer in front if you are running a 2" lift. Can anyone confirm that or have any part numbers?

Yup, 285/75/16 is about all you can do. Maybe a 305/70/16 with some trimming. But I dont reccomend it.

Thanks for the response. I'd really like more tire, but I guess it's not going to happen without a true lift... which pretty much can't happen due to clearance issues at my office parking garage. 6" on a real tire is gonna have me clipping supports.

Thanks again!

You might be able to fit it. My 305s fit w/ minor trimming and about 4-5 turns on the torsion bars. My advantage is the front end replacemment took away the bumper. I think it would fit but you would need to take it to your tire shop and see if they would let you try a set.

You have any pics of your truck with the 305's? Are they on the facotry rims or aftermarket?

I plan on installing 305's on stock and see how well it goes and then maybe add some 16X8's.

In this post, there is a guy asking about running 315s. In the post there is a link for pictures of a guy who is running those tires with keys and a block in back.

The guys is basically running 35" with keys and a bumper adjustment.

ChevyHDGert,

I run them on 16x8 american Racing and don't have any pictures but need to get some up.

I've been looking at upgrading my tires and wheels for my 2500 Yukon. What I've come up with so far is 18x10s with a 285/60/18 Nitto Grappler. The combo is about 1.5" higher than stock but the wheel diameter makes it look much larger. You can get 285/65/18s that are 2" higher than stock. From what I've seen, wheel diameter can make as big or bigger difference than tire size.

try some 255/85/16

You need to take the backspacing into account too. I don't have any rubbing with 285's on stock rims, but others with the same tires have rubbing problems on 8" rims because the backspacing was different.

This is my 03 with 285/75's I just cranked the bars and they clear fine, lock to lock. Oh and its a 1500

This is my old 02 with the same set up.

Nice banshee tungsten. I had a 92 and 96 now have a 01 raptor. Oh and nice truck

Thanks for the replies guys. I am now considering bumping up to 18's and truthfully from looking at the pictures the 285/75R16 do provide enough meat as well. I just don't want to buy another set of tires and be pissed off that they're still too small on the truck.

What are guys doing who are running the 17" take off H2 wheel / tire combos? Aren't those 305's? I don't remember the aspect ratio though.

Hummer tires are 315X75X17.

If you are looking for truck tires, the options get limited above 17" That's why I recommend the Nitto or BF Goodrich. The 18x10 wheels have a positive 1" offset which should fit within your wheelwells. Also, make sure you get wheels that are load rated for what you want to do with the truck. The load rating should be about 3,000 lbs each to match your tire ratings.
