I like my 255/85r16's
really depends on what your looking for..
mopar1973man drives 265/75r16 in winter and 235/85r16 in the summer for the added mileage. (both of those sizes are near equal in circumference about .2" off)
I went with my choice just cause it was an even step between the two with a little bit more added circumference which seemed to have helped with fuel mileage although I cant give you an exact number on that.

Dracozny, can you post some front and side pices of your truck with these 255's. I have been looking for a second gen 3/4 ton with these but havent had any luck. I like the way 285's look but have been thinking of going the 255 route becasue they are alot cheaper.

 

the only manufacturer for this size is cooper but you can usually find them rebranded like mine. check out the smaller tire shops in your area they usually can get you a better price.

 

I run 17's on mine and have been thinking about the BFG mud tire in a 255/80/17 but just can make up my mind.

 

Did you end up getting the BFG 255/80/17's? Any thoughts (mileage, too skinny, snow, etc.)? Glad for any info and pictures would be great.

 

Roughly for every 4 pounds of rotational mass you lose you need 1 less HP to keep rolling.

265/75 R16 = 85 Pounds per tire = 340 pounds for all 4.

235/85 R16 = 62 Pounds per tire = 248 pounds for all 4.

340 - 248 = 92 Pounds Difference...

Rotational mass (total weight) and rolling resistance (face width) make a huge difference.

 

On my old '99 I noticed a big improvement when switching from 285/75/16 AT to 235/85/16 HT. Mileage increased, slight increase on the butt dyno and the truck performed a lot better in deep snow. The best part is that they don't throw as many rocks against the truck.

 

I like my 285/75/R16.

 

265/75/R16's look alright on a stock height... I believe they come from the factory with 235-245/75 tires...

 

One tons came with 215/85's IIRC, but I think your right on the 3/4 tons, Don.

 

Because when I first got mine it had 245/75/R16's on it... I always said Dodge Wheel Wells are just massive, I got 265/75 BFG Muds now but Im planning on going to a 285/75 or a 295/75 next. I am just hesitant about the 295's rubbing?

 

No prob. You could go up to 305's before you get close to rubbing. 315's might rub though.

 

Alright. Thank ya sir Will! :thumbsup:

 

A lot of that depends on your wheel back spacing.

 

I have 285/75/16 cooper S/T Maxx like em so far. They had pretty good reviews

I run 315 70 17 on stock 08 rims on my 2wd 3/4 ton.

 

Does anyone know the max tire size I can run without rubbing (full suspension travel, etc.) on a 1999 4X4 with 3rd gen. alloy wheels?

Dealers say the 285/70/17 (~33.1" diameter) may work.

Also looking at the 255/80/17 KM2's (~33.3" diameter) but dealer was skeptical about rubbing.

If anyone knows the tread width of the 255/80/17 KM2 I'd be glad to know. Have found specs from 7.1" to 7.9".

 

I have a set of 3rd Gen alloys with 285/75x17 Nitto Dura Grapplers on my '01. Claimed to be nearly 34" diameter.

They do rub the control arm on a hard left but not too badly. I just don't crank it really hard and have had no real trouble. I also have NW running boards and with those even cable chains might not be a possibility. I believe cables would clear without the boards but it would be tough with real iron.

These tires are load range E with a load rating of 3970 lbs and also say made in USA on the sidewall. :thumbsup: :thumbsup:
