If you are planning on having a set of dedicated trial tyres, you may want to think about whether there is really a benefit in running expensive tyres like BFG MTs - the likelihood of wrecking a tyre is much higher, especially in quarry sites, so you may be better with a cheaper alternative and treat them as disposable.

Personally I have used more aggressive tyres for competition work where the rules allow - I'm currently running Malatesta Kaimans (essentially a copy of the old Simex pattern) on my Gen 3 - they're incredible in deep mud and also shrug off rock damage very well.

Just a thought...

That’s a good point, I have had a look at other makes, including Maxxis (they don’t seem to do any MT in the size I am looking at) and Insta Turbo, but I have always kept clear of remolds.  The other question is what I can find local to me, I don’t really want to buy tyres on the internet, then find a tyre fitter, I would rather get the tyres and fitting arranged together if i can.

I have had more brands of tyres on my Jimnys than any other car, the last set Maxxis Worm Drive have been the most expensive, but I have to say the best so far, so I don’t mind spending a bit more for a known quantity and something that performs.  I used to race a large sailing dinghy, we went through buying more cost effective sails until a good pal said, if you aren’t winning races you never know if it’s you or the gear and if you use the same as everyone else and still don’t win, at least you know it’s you.

As I mentioned before, I am open to all ideas, so thanks for your post and keep the ideas coming.

Generally remoulds are the tyre of choice for trials events, as much more aggressive tread patterns are available. In muddy conditions they will easily beat names brand MTs like BFG KM3, General Grabber X3 or Toyo MTs.

The best tread pattern can vary for different terrains to some extent. Not sure what size you'd for your Jimny. In Japan they seem to run 6.50 x 16 which is a size you can get in mainland EU, but pretty much no chance in the UK. A 205/80R16 is quite close, which is what I'd like. but you'd probably want a lift and 16 rims.

As a rule I find tall narrow tyres work best in the UK off road and usually offer better turning for trials sections.

On my Land Rover I trial with a set of 7.00 x 16's, while for general use I run 33.10.50R15's.

Sadly remould tyres and decent aggressive ones are not easy to get in the UK currently, so choice is a bit limited.

Something like this would be a good trialling tyre:

A couple of quick questions, how long did it take you to fit and did it change your insurance?

Robin

Me & my brother fitted the kit. Think we started about 10-10:30am in the morning and finished about 5pm that day, with a lunchbreak. You could do it quicker, but we didn't rush and hadn't done a Jimny before, so had to figure some bits out.

This was 4 springs, 4 shocks, extended brake lines, including a new front subframe and the LED headlight adjsuter.

The next weekend we fitted the castor correction bushes. Which only took a couple of hours.

Insurance was no problem, no additional cost, just listed on the policy. I'm with LV.

Ok so it's time for me to be that guy again. If I understand it you're being motivated by a couple of things first being beaten by land rover products in competition and secondly by having dragged your diff guard.

First off trying to win in an open class at any level of motor sport is simply an expression of who has the deeper pockets. You turn up in a jimny having spent a few thousand pounds on it and win, yay! I turn up the following week, having seen your efforts, and I have spent 20 times as much on a very special ibex and you never podium again unless you match my investment. Motor sport is almost as good a way of becoming poor as being a farmer is.

Moving on. The diffs on a jimny are not as delicate as you think, certainly not like a land rover, so from a protective point of view guards are rather debatable. Not to say they don't have a place if viewed as a skid to stop objects snagging as they do that quite well. However they are not exactly close fitting and there is the material thickness they are made from too. So effectively by going for the bigger tyres you are looking at you are returning the diff height back to where you started but you are having to buy a lift kit and bigger tyres to do it, which is both expensive and puts additional strain on the rest of the car. Of course this also assumes that the tyres you buy are actually the size they say they are. My renegade at5 are 5 to 6mm smaller than my worn duelers and in turn they were 7mm smaller than the bfg urban I used to have but they are all 205.70.

Ultimately it's not my choice but you have asked for opinion.

To some extent I agree about money and motorsport. But I’d say less so for trialling. Very often well driven standard Land Rovers best modified ones. 

I don’t know the regs where DrRobin competes or the types of trials. But as a rule smaller vehicles often do better. But more challenging terrain favours Land Rovers. Due to standard tyre size and better suspension flex on a Land Rover. 

For instance. My brother and I setup and RTV a few years back where a number of Jimny’s and other Suzuki’s entered. I heard complaints that it had been setup with lockers and 35” tyres. I interjected and pointed at a completed standard pickup 90 and said we’d setup in that. 

Good job I got the diff and transfer case breathers done....

Not at all Lambert, in fact thanks for been 'that guy', your opinion is always welcome.  The thing is I realise I am not going to win or at least win very often and to be honest, most of the others at the local club have been doing it for quite a few years, even if you plonked me in one of their vehicles, I still wouldn't win.  My interest in a lift is just to get a bit further through the stages or complete a few more, I can put up with been mid-table or even last.

The rules at the club are fairly loose, but you have to drive there and the vehicle has to be road legal, plus there are no prizes, not even a trophy, just a good friendly day out.

I can't see myself spending multi-thousands trying to make my Gen 4 be ultra competitive, as you point out it would be self defeating and if I was going that route and sticking with a Jimny, I would be buying/building a special, that's definately not happening.
