Thread: Biggest and best tires for Perentie 6" rims

The 235s are a little wider, but diameter is the same.

255s are generally accepted as ok on 6.5" rims. For what you want, I would just run a single set of 255/85r16s all the time. Two sets of wheels with slightly different sized tyres is a waste, for all the time and effort it takes to switch them over you'll just leave one set on. Trust me. Maybe I'm just lazy

I won't be swapping between the Olympics and the 235/85s. As described in the original post I'll be running 33x10.5R15 in mud and want an alternative tire for sand and trips elsewhere.

After doing some tire calculations

255/85R16 seem like a good size, now let's see what I can get with that size...

I wouldn't have a problem running 255/85-16 on 6" rims. They will be fine. I prefer a narrower rim as it gives you less chance or damaging the rim or losing a bead when aired down.

I have 285/75-16 (33") MTRs on one vehicle and 255/85-16 (33") Maxxis Bighorns on another. They both get used for everything: Mud/sand/road/long distance touring. Both are on 7" (modified Disco 1) rims, however the 255's could use a narrower rim.

IMHO it is better to buy one set of tyres rather than 2 sets that get old and hard and need to be replaced when half worn.

Really? I thought it would have worked the other way around? (in my head atleasr)

My idea was to get cheap all round tires and flash mudders, but if I have to replace them after little use and sitting around all year, then maybe not. How easily and fast do tires expire from sitting around?

I have never rolled a tyre off a bead. I usually run my tyres at 7 psi offroad. I have seen plenty of people roll the same width tyres off 8" rims.

Current recommendations are 6 year life for tyres. In NZ they will probably stay soft and supple for longer though due to cooler temperatures and less UV/ozone.

At the end of the day though it will probably cost you more to run 2 sets of tyres.

In the 255/85 size there are 2 main choices, BFG km2 muddies or Maxxis bighorn muddies, both go for around the 300-350 price, sometimes less.
I have the maxxis on my defender and they have been good, better than the old 235 /85 cooper st/bfg at combo the previous owner had.
The one thing to consider is the offset. I have a longer travel setup and the 255's would just rub on the rear spring mount top plate at full articulation on the factory alloys(+33mm). I have some wheel spacers to stop this(take it to zero), or you could just get the wheels at a further out offset, +20, 0 , -15 or -25.

Yup those are the only two tires google could tell me.

As for clearance 16 inch rims in different offsets are impossible to find here and Spacers are illegal unless certified. So not sure how I will get around those.

Thanks for all the information so far guys.

Stay on the stock rubber size...

Bfg MT range is good and run on of the MAXXIS numbered range for about the same performance for a lot less buck.

By way of example
The maxxis 980 is a drop on replacement for the BFG AT as fat as performance goes.
