Mud Tyres

I have a set of 205/70 R15 INSA Turbo off road 4x4 tyres on our Jimny but they are no good in our muddy field.  I am looking at getting a set of BKT Agrimax RT-765TL 200/70 R16 tyres and changing to 16" rims 6" width.
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

Welcome to the forum. Are you planning on using it on road at all? Have you looked at things like the maxxis m8060 trepador, they are available in 205.70r15?

There are lots of tyre options in 215/75R15, which is about the biggest you can fit without a lift.

You may also get better results with the tyre you have by lowering the pressures.

Thanks for comment Lambert. I have got the 205/70/15 INSA TURBO SPECIAL TRACK 2 MUD TERRAIN 96Q which looks a similar tread pattern to the maxxis m8060 trepador that you kindly suggested. Are the Maxxis far better in mud?

Cheers.

Hi, 
I personally think you are on the verge of spending £££ on new tyres with only marginal improvement if any. The tyes you have should be good enough if they have enough tread depth, so as suggested already try altering the tyre pressure.
Having said that some "claggy" mud is just impossible, it bungs the tread instantly and reduces traction to ice levels.
But if you want new tyres why not, best place to ask
Hope you find what you need.

Thanks Scimike, I agree with your comments and might try reducing the tyre pressure more, thanks to Saxj for that suggestion as well.  There is plenty of tread on the tyres as they are brand new, but we have been really unimpressed with them, the mud did fill up the treads and they were slicks, so totally useless.we have had to use the Disco, on all terrain tyres, to tow it out of the field. 
We don't really use the car on the road, other than fill up with fuel.  
The tyres I am looking at are tractor tread, see photo.  They will go on a 16" wheel and are 686mm diameter, which is fine. 
Thanks all.
