Mud Tyres

If you are finding that Insa special track are running out of talent in a field then there's really not much else that I can think of that will do much better. It must be really very wet and or clay conditions? Also and this is not meant nastily are you sure the 4x4 system is functioning correctly, it's just that I'm a hill farmer and I travel perfectly adequately on road pattern tyres on my land as long as I don't deliberately drive through the obviously soft ground and carry a little momentum.

Just looking at the bkt you mentioned above and the speed rating is limited to 25 mph which as I understand it is illegal for use on a vehicle that can exceed that speed. Plus it being an agricultural tyre is going to immediately be of interest to the constabulary if they see it on a car in the local petrol station.

I have searched for 6 x 16 and you just can't get them in UK 
You can import from Japan if you have silly amounts of money
 

Are you digging in and creating deep ruts, or are you spinning on top of the ground?
My only real experience with the Jimmy is trialling so we obviously get directed towards the worst ground conditions, we often cross deep ruts, or try to steer out of them, it's hard to imagine conditions that would defeat the Jimmy unless you have ruts which leave you high centred.
In my experience the one thing the Jimmy doesn't like is steep climbs with an axle twister involved, here I think the light weight is a disadvantage. The Jimmy's in our club very rarely need recovery.

Has anyone any experience of these tyres, or know any better mud tyres suitable for the Jimny??
Where can I get some steel 6" width 16" dieameter wheels to suit Jimny?

Thanks

I just want to check. The tyres you say you have are these?


If so, they are very aggressive mud tyres. You are unlikely to find much better.

A full on Ag tyre might offer a bit more traction, but it is likely to be marginal.

Can I ask, what type terrain/mud are you driving on? Are you in the UK, if so, what area?


You also mentioned about a Discovery on AT's rescuing the Jimny. I assume you meant to drove on the same ground with the Disco?

This would then lead me to also ask:

-Has your Jimny ever been any good off road or have you only just got it?

I ask this as maybe it isn't a tyre thing. Are you certain that 4wd was working? If the vehicle was in 2wd with open axle diffs, you would essentially have 1wd. Which on a slippery muddy hill would get you know where.

Pretty sure it is legal to run lower speed rated tyres. You'd just need to notify your insurance. e.g. Many modern SUV/4x4's have pretty high top speeds, but you can still legally fit and run Mud Terrains on them with lower speed ratings.

For example, my 4.6 Range Rover is rated at 124mph top speed. I believe a set of BFG KM3 MTs are Q speed rated which is only 100mph.
