I request pictures!

You've seen the picture I took before... you know, in the thread where you called me an evil evil man. :flipoff2:

I'm dancing back and forth between the 235/85/16 and the 285/75/16
Also trying to get a good measure on my rims to see if the 235s will fit
And I'll post a few more times and then post some pics
 
Rick;

285s will kill your on highway performance, there's just too much rolling resistance in them.

255 85R 16s are about 33.5 x 10.50, so they are both taller and a little wider than the 235 85R 16s. These are both a heavy duty tire with low rolling resistance, and typically are a D or E rated tire - good for gravel roads and heavy loads. They also typically run at higher pressures - max pressure will be as much as 80 PSI with a good running pressure in the 42 to 50 PSI range.

Toyo M55s and MTs are nice, the M55s will pick up stones a lot (think Bowmen driveway - lots of small stones what will get picked up and tossed out all the time). The Coopers are a very good all round choice in either size and tend to run at somewhat lower pressures than the Toyos.

The other option for 15" rims are the 33x10.50 offerings of a few manufacturers - essentially the same size as 255 85R 16s, but with somewhat less load carrying and a slightly softer ride (operate at lower pressures, usually).

MTs are not very good in icy conditions. The Coopers will do better given snow/ice. M55s - do well, but the stone picking up issue is something to think about, really.

Under an inch difference in width between 255 and 285, and that is going to increase rolling resistance so much that it is going to 'kill your on highway performance'?...I don't beleive that story.

Rolling resistance doesn't affect performance that much, it is a 70 series brick being pushed through the air after all, and the difference between the two tyre sizes would create only a very small difference in overall performance, if even noticable.
 
got 285/75/16 on mine and I do like them but would like to try 255/85 16 next time. I run kelly safari TSR close to dura trac bu less money . A very good value
 
Thanks!
Well, I was happily going down the 235/85/16 road and had narrowed it down to Michelin LTX MS2 or BFG AT
Now I"m considering the 255/85/16 option again. The greater height would be good. I've been a fan of the LTX MS over the years but they don't come in 255/85/16.
I'd like to avoid the stone chuckers - especially since I just had the windshield chip repaired from someone throwing one at me.
Anybody make something like the LTX MS in the 255 size?
 
diff-locks? Looks like a nice truck.
You'll have slim choices finding rims but there are a few out there with the correct offset.
I hate wheel spacers so I would say research them a bit. You can buy some plain janes right from toyota.
They look half decent too.
 
Thanks, Unfortunately no diff-locks!!!!
I'm thinking of just using the rims I have - they are 16" and measure at 7" wide - even though they look wider.
The little studs around the wheels are coming out - thinking of just pulling all of them out and being done with them - anyone done this on these wheels?
 
7" rims are perfect for 255 85s.

Try Justin Hollett @ B & H Tire in Chemainus (say you were talking to me) - 250 246 4731.
They carry Toyo & Cooper, among others.

255 85s are limited in who makes them, but they are an interesting size option.

235 85s are made by most manufacturers - so lots of selection.

Thanks, John
Yeah, they will also be fine for the 235 85s
Any advantages of the 255 over the 235 other than the diameter and I'm assuming resulting fuel economy?
 
I run 255/85/16 bfg muds on my 74. Should I air down to 25psi for driving in 5"to 6" of snow? Any ideas.

Air down to whatever you wan to, but if you air down below about 20 PSI, you have to keep your speed down.

In deep snow, I'd go to 10 or 12 PSI, and in reallllllly deep snow - 255s are the wrong tire to run.

With 33x12.50s in deep snow, I will go down to 4 - 6 PSI or even lower as required. You have to keep your speed very slow when aired down that much, and when you're back on a hard surface, you'll need to put some air back in if you want to go any where.

okay,
tires, ice radials for winter. lots of info on this site about which and why.
stock truck then run the 235/85/16 Nokian, Blizzack or even CT ice radials.
change to a summer tire come spring.

i run a 32" ice radial in the winter and a 35" tire in the summer. 2.5" lift is a nice goal for next year once you are used to your truck.

lock the hubs BEFORE you need them, you can shift on the fly at any speed in and out of 4wd. if the hubs are not locked then you get this really not cool grinding noise that sounds a lot like money.

ice radials are great in deep snow as well as i have found when wheeling in Alberta foot hills for a few years. smaller ice radials will go further than huge mud tires.

2 sets of rims is nice too, easier and cheaper to just bolt rims on than getting tires changed all the time
 
Thanks everyone!

I had a great chat with Justin (John's recommendations) and was heading back to the 235/85/16.
And then the recommendation by crushers confirms this.

Thanks crushers for the other tips - much appreciated.

This may help. Left to right. 235 85r 16, 265 75r 16, 285 75r 16, 33x10.5 r15 and 255 85 r16. First three are toyo M55, fourth is a bfg mud and 5th is a half worn old bfg mud.

I prefer the 285 as the tread opens up enough for descent wheeling and I don't believe economy will suffer that much. The 255 is a good mix between height, traction and fuel economy. The 235 is great on road but packs up off road. The 33x10.5 is great also, except for carrying capacity. It all depends how you are going to drive this truck. As Crushers says if it's for winter driving, there is no substitute for a winter tire in any size.

Take care.
