Title: what tyre tread are you using offroad?
Post by: tartanzj on May 02, 2008, 05:41:55 PM
Well I've got my spare wheels now and have to decide on tyres.

I am looking at getting some 235/85r16

My reasoning for this size is there are a little bit taller than my 31" AT's and being slightly narrower will bite down better. They are a common LR size so are pretty cheap and easy to get hold of. Also they shouldn't be much heavier than the 31's so hopefully won't increase the stress on the steering components.

My question is what do you think is the best tread pattern for purely offroad use, mainly in clay and mud conditions. They must be road legal too.

Please give me your views on your experiences

Insa Special Track: Simex copies and cheap (Paddock 4x4)

Or

Iterco Super Swampers: Never used them but 1000's of people do! Expensive though :cry:

yup. anythin with a simex or bogger tipe of pattern. be aware that you have a d35 rear axle and increased grip will cause increased stress on a weak link. 8-)  the recip tyres are also pretty aggressive.

I'm with greggmo, the axle will not take the extra stress especcially the Recips they grip like hell

The gearing will suffer badly as well, be careful you don't cook the gearbox, I did on 31's with a trailer on

Yea I'm concerned that special tracks might be too aggressive but I was hoping a few of you had used something between this and a standard MT pattern that you might recommend. Generally most of the normal MT patterns don't seem to self clean very well. Has anyone tried a diamond pattern?

When I was trying to keep my vehicle dual purpose the only tyres that really do the trick are General Grabber MT or BFG MT they are lightish and balanced and you can still drive like it came from the factory ....almost.
I tried Bronco dirt devils once. Bloody things are half the weight again and don't balance easily and then you run em as I did all the way to Seven Sisters and they have taken a different shape and are not in balance anymore, they ride like US Swampers they are not round when cold and should only be regarded as tractor tyres. Bloody good when you get there mind can't fault them for what they were designed for just don't use them on the road. Unless you want to go everywhere at 50
I've use BFG MT on my YJ OK they're 35s but at least I can hot foot it to Tong at 75. A mate has 35 SX swampers and the buggers are so heavy and out of balance that 50 is tops and you can feel all your wobbly bits wobbling as you go along.
ON a Grand that would trash the axle, trans and turn a plush ride into jello.
Only real way to have dual situation is a small trailer with your severe offroad tyres in.
Otherwise BFG MTs and let em down to 10 psi.. Iknow    it works.

Cooper Discoverer STTs - I've been running them for a good couple of years now. They are almost a true size too i.e. 33s do actually measure 33 inches tall. They are great on the road and provide great traction off road too due to side lugs and clearing sips [sp?]. Quite a sticky compound and they wear quite well too. You can also apparently air down ti 8psi but be very cautious when airing down (I don't bother).

They're re-moulds or re-manufactured which does raise the price considerably.

How do the Recip tyres measure up? Are they a true size, My BFG's probably measure around 30.5" for a 31" tyre.

Seeing how the original question stated purely offroad, I'm with Warthog for tyre choice.

The Mickey Tompson recipe patern copy like most all are undersize to what is stated. But not by a lot.

Has anybody used (or seen in use) the Kumho KL71 tyre. It looks to have slightly wider spacing between lugs compared to a standard MT pattern.

Price seems pretty good too as its not a remould.

They are very good off road IMO, the sidewalls arent the best but I aint had a problem yet. They don't seem to be wearing that well but I spose you get what you pay for..
