255/85/r-16

How much lift do I need to fit 255/85 r16's and would you recomend a gear change for these?

None and no. They fit without any mods. Change in gearing will be 3% or so. If you are happy now, it should be fine.

I think the speed change is negligible with the tires, my speedo is 5mph slow. I thought those tires would rub some at full steering lock.

Russell I run those tires as well, and with them my stock speedo it spot on... it was off a bit with the stock tires. As for install / purchase, lots of us use VDO vision gauges, as they fit perfect and look a bit like the existing tach gauge. Installation might be local speed shops or mechanices. The install is pretty straight forward on a '97 since you already have the right sender.

Sorry, you might need to adjust the steering stops. I don't really think of that as a mod.

Every Rover speedo I've seen read low and larger tires help fix it. If it is a problem, the VDO Vison Speedo would be the best fix as it can be adjusted for any tire size.

You won't need to adjust the steering stops, as the 255 is narrower than the stock 265. You might be able to gain a little on the turning radius if you actually adjust them in a little, (I did) but you won't need to do that to fit the tires.

I've only seen the 255/85/16 in the BFG MT.... Does anyone know of an AT that comes in that size?

I think with my wheeling style the ATs would be good enough. Given it's my daily driver, I'm always looking to better the drive.... Less resistance.

Cooper Discoverer ST is an agressive AT. It can be had in a 255/85R16. I have 265/75R16 ST-C's on my Disco which is my daily driver. Same tread pattern, thicker sidewalls. Quiet and well behaved for that agressive of tread. Great in snow. A hell of a lot better in mud than the BFG AT-KO. I don't think Cooper is currently making the 255/85 in the ST-C.

I'm currently running that size with a 3" lift. Good tire size for mud. Rocks tend to eat your rim though.

here you go. This is with about 2" OME lift (probably more like 1.5" now from time)

sent you pics via email. my set up is similar to Chris'. my pics were taken while on a RPI ramp so you can see how the articulation figures in the mix. i think this tire size works real well for everything (mud, snow, and rock). i have a solid 2" spring lift using med-duty springs and EE spring isolators.

overall i think so. im struggling with some vibration coming from somewhere (tranny or driveshaft) and so it hurts the total effect. the additonal height is nice though; makes the whole truck sit just right.

They are the BFG Mud Terrains--the road noise is acceptable, much lower than a swamper. I have not had the pleasure of a ride with the MTR's , so I don't know how they compare. Personally, I don't think it is too loud a tire--one of the quieter mud terrains. Also, the 255/85 combo is relatively light--some of the larger wider tires get very heavy.
