235/85 r16 Vs 265/75 r16

Post by Tobias »

Getting new set of rubber soon (currently running 31/10.5/15) i''m going to be using disco steel rims. Has anybody got any comments on which size to go for 235/85's or 265/75's? Does the extra width of the 265/75 offer any great advantage over the the slightly taller 235/85's? has anybody used both sizes before? i've seen defender owners change from 235/85's to 265/75's before is that just for looks? The terrian i travel ranges from sand to mud.

The pros are that you can safely run lower pressures. This allow better traction and floatation.

The cons are that it uses more power.

What engine do you have?? Personally, I think 285/75/16 is a great size for a Defender.

you can get a bfg mud terrain in 255/85-r16, about 33 inches tall but still not to wide. i'm a firm beleaver in narrowISH tyres as they don't have as much rolling resistance but in a tall tyre aired down will still have a good footprint. i drove all over fraser island on 750-16's xzl very mud baias and had no dramas. just my opinion

yep, you can get 255/85/16's from BFG and Cooper (STT)
Gives you a little more clearance under the diffs and a bit more width than a 235/85, with the height of a 285/75.
Can mount them on a 6.5" Rover rim, and looks stock.
Stuffs up the turning circle a bit on stock offset rims.

Hi

I have 3 sets of rims and tyres for my County, all on Disco steel rims:

* 235/85 Cooper STs
* 265/75 Cooper STTs
* 265/75 BFG AT's

I also used to run 235/85 BFG MT's.

The problem with the 265's is that they rub on the rear spring mount on full compression. I am contemplating getting the rims offest to assist with this and perhaps modest gains in turning circle and stability.

I do not notice any difference on sand between 235 and 265.

I run 255/85r16 (33") Cooper ST's on my disco with 1.41 defender gearing.
Ideal tyre size for highway/touring km's. Cuts the revs and noise down and gearing is similar to stock disco with 29" wheelbarrow tyres.
