Pointers please towards a gentle intro to green laning and off roading.

Having read the tyre wiki (which is really good) I am aware of the need to have all 5 tyres the same and not tyres with a rotational direction (as they can't be rotated except on one side - and the spare would only suit one side!). That would exclude the BFGUs unless I am looking at the wrong model of tyre - there are so many on each site!
The general Grabber AT3 looks like it would fit the bill.
So is there any advantage to getting a wider tyre and I don't want it catching on my unmodified wheel arches.
I don't want to kick off a huge tyre debate, this is just me going mainly on the road and occasional fields and lanes.
Thanks.

Grabber AT3 are a good bet or Yokoharma Geolanda A/T-S.(go-12) not much point going wider but possibly taller to gain clearance under the diff's.

If I went for Grabber AT3, which seem to be available in all sizes and profiles, how do I go taller without wheel arch issues? What profile would I look for on a 205 to 225 tyre on a 15" wheel with no mods on the car please?

205/75/15 or even 215/75/15 will go on a standard jim without any mods. 215/75 is the limit though and if you have the later type bumper they may just touch the corner on half lock. Just need to trim about an inch of the bumper. No problem with the arches.

Thanks guys, I think I might just opt for General Grabber AT3s in 195/80/15 and get a set of 5 to rotate them.

After I repaint the rims... Hammerite?

195 80 15 is a nice size mate. Doesnt alter economy much at all. 215 75 are an inch wider. More rolling resistance.

Look up 2 wheel low box mod. Puts a switch in so you can drive in 2 low. Much better for lanes.

All the best

On a standard one the 195/80 fill the arches nicely. This is marks one on a lane trip earlier this year.

Phew - I thought that might be much more of an issue for me!

Last question (maybe!) what pressures do you run on the road - and I presume you consider dropping a bit for longer off road sections?

Start at 25psi all round see how it feels
My 195 retreads i settled at 20 all round and 15 off road

I run my Grabber X3's (215/75/15) @ 20psi all round and don't bother letting them down for competitions as they work fine off road at this pressure.
