Thread: Please help me choose tyres for my 300tdi d1.

if you just want muddies for the reason that they don't clog up in mud, then just about any muddie will do that job for 'ya.

If you want better grade of muddies that will also have half decent performance on road .. noting that most of the days drive will be on the roads to where the mud is! ... then you need to be careful of the choice of muddie.

I'm not a 'muddie' type user, I hate them. Far too much noise and (by comparison) zero grip on wet tarmac. I only ever get AT types.
Some AT tyres with a half decent aggressive tread can do really well in mud, my only experience with this was a set of Pirelli AT types that worked really well. But no longer available

Can't help with what brand to go for in terms of muddies(never had them).

In terms of size, you can easily go 245/75 16's on a D1 without any issues.
255's will rub(front) on full lock, unless you adjust the lock stops to eliminate this. But this could also depend on wheel offest(you have).

Only thing I know about Kumho muddies is that brother had a set(on a Patrol, in 33's) and they were horrendous. Punctures galore and hard to balance too.

My choice is Goodyear MTR, an excellent tyre with traction and an incredibly strong carcass. Noise and vibration is also really good for an open pattern tyre. I know the BFGoodrich is popular also.

Thanks guys, plenty to think about there. All about finding a good compromise I guess.

The Kumho MT KL71 (TyreShopOnline: Mud Extreme 4x4 Tyres) is within my budget - has anybody used these themselves? They're not available in 235/70 R16 though. Relative to the 205 R16 what difference does the extra 30mm make? The 225/75 is only 14mm greater in diameter than the 205, but I really don't think I can be bothered with this "camel cutting" business if they don't work out. Please discuss:-)

I have run a number of sets of KL71s in various vehicles and rate them very highly. They work well enough on-road to be a daily (keep them pumped up though) but don't seem to give up anything off road. Never had a puncture either. No Camel cut required for 225/75R16. I run 265/75s and only had to push the rear guards outboard a bit (extend the tie-bars at the rear) and do some very minor trimming of the return lip (not visible). A mate had to do light trimming to run his KL71s in 245/75.

I have Dunlop AT3g 245/75/16 on mine and they handle well and see3m to last well. They are an AT tyre, but have a reasonably aggressive tread in the bush.

Thanks. What is a good road pressure for 225/75 R16? Currently I go by the book ie front 26psi, rear 33psi - that is for 235/70 though.

Unrelated: Just shopping for a donut and came across roverlord.com.au - is that the guy on here? Doesn't look like he posts to NZ:-(

Mario (Roverlord) is a legend. Email him at info@roverlord.com.au and see what he can do. He has really helped me out over the years. Not sure if he posts to NZ but you could ask him for sure.

I run slightly higher than 26 in the front because I have a bull bar and TBH, get a less wandering feeling at 30psi. I have the rears set at 36psi because I have a kaymar rear bar.

The best way to test if your tyre pressure is correct is the 4psi rule. Put the pressure in you think you need. Drive for five minutes - preferably at speed. If the tyre pressure has increased by 4psi, you are at the right pressure. If it is higher, your pressure is too low and your tyres are producing excess heat. If its a less than 4psi increase, your tyres have too much pressure and should be reduced.

If you can’t be bothered, stick to factory specs. 😂

As the KL71 muddies have a centre strip for on-road I'd recommend bumping them up a bit over the factory numbers. That ensures that they mainly bear on that spine and don't hammer the lugs too much. IIRC I ran high 30s for day-to-day highway work and low 40s for heavily laden. Front and rear. I'd run what feels right through the steering wheel and seat of the pants and also gives you 4psi or less pressure increase over about 30-45 minutes of driving from cold. And don't be afraid to drop them to the low 20s when off-roading (less for sand). If you run lower pressures on-road than they'd like you'll hear and feel it, but they will feel like you are traversing a mild cattle grid at walking/jogging speeds at any pressure....
